Is your AC unit properly gassed up and functioning correctly? Do you receive the occasional warm or hot shot of air when you turn on your AC unit?

If so, chances are your AC system needs attention in two areas: regassing the condenser, and/or the electric fan may need replacing. The re-gassing of your AC Condenser is a very specialised job and should only be undertaken by a qualified technician.

The other vital and important component to your AC system is the Thermatic^® Electric Fan. It effectively pushes or pulls air through the air conditioning condenser to assist with heat transfer thus providing refreshing, cool air into your cabin. The AC condenser is the major component and functions as a heat exchanger for the AC system, converting the refrigerant from gas to liquid so it can flow through the AC system.

The heat generated can only be expelled if a strong efficient Thermatic^® Electric Fan is installed, stating that a strong Thermatic^® Electric Fan with a high wind force (CFM Cubic Ft/Min = ft3/min) is essential to keeping the AC condenser cool so it can continue to efficiently convert the gas into liquid and keep the AC system functioning as designed. The stronger the air flow across the condenser, the cooler the air which can be generated inside the driving compartment. A defective or inefficient electric fan will be detrimental to your entire AC system.

Davies Craig warns that a proliferation of imported fans has emerged over recent years which are very similar in appearance while having dubious performance. Consequently, these units are not fit for purpose as they do not generate sufficient, effective CFM required to produce sufficient cool air flow through your vehicle’s air conditioning system.

Davies Craig has been manufacturing high performance Thermatic^® Electric Fans for more than 50 years and offers a wide range of Thermatic^® Electric Fans manufactured from strong, heatresistant 66 Nylon/glass, offering high air flow, low profile and low current draw. They also now have a three-year warranty.

Davies Craig says every one of its Thermatic^® Fan models have been put through exhaustive durability and certified wind tunnel tests to ensure each delivers high, accurate air flow and CFM (ft3/min Cubic Feet per minute).

Every model can be installed in either ‘pusher’ or ‘puller’ configuration by simply reversing the blade and polarity for bi-directional air flow.

Davies Craig also recently introduced four High Power and four Brushless Thermatic Electric Fan models to complement the existing Thermatic
Electric Fan range. It says each of these models delivers a 40 percent
higher CFM than their standard equivalent models and importantly, enjoy the same mounting profile. Models are available to suit 12V and 24V electrical systems.

All Davies Craig’s Thermatic Fans offer reverse polarity allowing each fan to be installed either in front (pusher) and/or behind (puller) the condenser.

Davies Craig Electric Water Pump ~ size and performance.

It’s said that size doesn’t matter. Vehicle engines are supplied in a variety of capacities and have done so since they first rolled off the production line. One can head into a car showroom or log-on to a website and be greeted with engines from a mere one litre to 7.5 litres! Therefore, each car’s cooling system designed for a specific engine capacity will require a differing cooling system.

How It Works Without An EWP^®.

Let’s take a quick look at how a mechanical water pump system operates. Whilst an engine is not running, there is no coolant circulating through the engine, as the radiator or heat exchanger requires coolant to be physically flowing through the radiator core to “exchange heat” and keep the engine at a manageable temperature.

When the engine is running it drives a belt-driven mechanical water pump which is generally mounted on the front of the engine block. The engine’s mechanical water pump design propels coolant to and from the radiator. In simple terms, heat soak occurs when the engine or its components remain extremely hot, even after turning off the ignition. The downside to the old mechanical water pump system is that once the engine has been switched off there’s no coolant flow with the result that ‘heat soak’ develops. Higher capacity engines, or engines underload generate a lot of heat and therefore really need a more efficient method of cooling. This is where a Davies Craig Electric Water Pump (EWP^®) can make a huge difference. Which model Davies Craig EWP^® will best suit my engine for the optimum cooling performance? Check out the Davies Craig website, www.daviescraig.com.au https://daviescraig.com.au/electric-water-pumps  

What About Performance?

Davies Craig Pty Ltd is a renowned Australian owned and operated manufacturing company of 50 years standing and offers a wide range of automotive aftermarket Electric Water Pumps and Electric Booster Pumps. The so-called EWP^®s are ranked in reference to the coolant flow capacity, litres/gallons per minute. There are currently four Electric Water Pump models and it’s important to note the intended usage against the flow rate per minute. There is models, EWP^®80 that will generate 90 litres per minute, EWP^®115 generating 139 litres per minute, the EWP^®140 generating 147 litres per minute and the EWP^®150 generating 162 litres per minute. The EWP^®150 is intended to be used in high performance, turbocharged/supercharged and large cubic capacity engine applications.

For example, your vehicle has a fuel injected 350ci or 5.7L Chevrolet V8 engine. It’s been “chipped” for better performance, then obviously an EWP^®80 which is intended for an engine capacity up to 2.0 litres, t wouldn’t be suitable. On the other hand, the EWP^®150 which pumps out 162 litres per minute would be the matching product to suit.

At the other end of the spectrum, installing an EWP^®150 into a 2.0L engine, this model more than manage this engine but would be an ‘overkill’ for this engine. That is, of course, presuming it’s a stock engine and being used for nothing other than normal driving. Hook an EWP^®150 to a race-spec 2.0L being used in a drift or burn-out competition.

One significant advance in fuel economy, emissions reduction and power train performance lies within one single area of the vehicle: the engine’s cooling system.

Electronics and new digital technologies are playing a greater role today in the management of vehicles’ engine cooling system and delivering outstanding results! Traditional mechanical cooling systems rely on an engine-belt-driven, iron-age mechanical water pump, a restrictive thermostat, and a radiator — all of which add considerable weight and consume the vehicle’s engine power. While these mechanical systems have met basic cooling system needs for several decades, the pace of change for engine cooling is evolving as fuel prices escalate and increased Government Regulations focus on reducing vehicle emissions.

Advanced 21^st Century cooling systems such as Davies Craig’s range of remote mount Electric Water Pumps, Electric Booster Pumps and the LCD EWP®/Fan Digital Controller enable internal combustion engine (ICE) to operate at more regulated temperatures with far greater efficiency.

A Davies Craig Electric Water Pump (EWP®) combined with a LCD EWP®/Fan Digital Controller provide more precise thermal management for ICE and hybrid powertrain systems.

These smarter cooling systems feature high performance Electric Water Pumps, such as a Davies Craig’s Electric Water Pump (EWP®), patented LCD EWP®/Fan Digital Controller and Electric Booster Pump (EBP®) to complement Electric Thermatic® Cooling Fan/s. The installation of these Davies Craig components reduces engine parasitic power loss which is achieved by controlling and varying the coolant flow rate independent of the engine's speed. This improves performance in demanding low speed, high torque operations, including towing and off-road driving conditions. Importantly the LCD EWP®/Fan Digital Controller, at the same time, provides heat soak protection as it continues to operate the EWP® and Electric Thermatic® Cooling Fan even after the engine is switched off!

Davies, Craig’s range of Electric Water Pumps (EWP®) can deliver between 3% to 5% improved fuel economy, while further lowering environmental impact by reducing emissions. Such benefits are achieved as these more accurate thermal management systems enable engines to reach optimum operating temperatures faster, thus increasing more efficient combustion.

In addition to engine cooling, the EWP® and indeed the range of Electric Booster Pumps are suitable for charge, water-to-air coolant circulation for increased performance and hybrid vehicle power train cooling and thermal management for electric vehicles.

Electric Water Pumps and Electric Thermatic® Cooling Fans coupled to the LCD EWP®/Fan Digital Controller can be simply be retro installed to most engines and offers the optimum engine cooling efficiency. Engine management systems are evolving rapidly, and thermal management systems such as the range offered by Australian manufacturer Davies Craig Pty Ltd are constantly evolving to keep pace.

The performance, efficiency, and environmental benefits provided by enhanced cooling management technologies are compelling. These advantages will become even more crucial as stricter environmental regulations are introduced, along with consumer demands for more fuel-efficient vehicles.

Car came a with a brand new short block, so while building I added a slightly hotter cam and went for full fuel injection. When finished, it was around 205bhp at the wheels, which was pretty lively in a car weighing in at 670kgs.

One issue I had early on was cooling, there are two headers in a very small engine bay, and the maximum frontal area of the radiator is limited to around 11 inches, which quite honestly is too small for a mildly tuned V8.

Cooling while the car was moving was generally ok, but being stopped in traffic would see the engine temps rise quickly, and the fan and rad would really struggle to keep temps below 100 degrees when the pump was spinning slowley.

Having tried different cooling layouts, and even installing the highest possible flowing fan it was time to make the move to an EWP^® to increase the rate of coolant circulation while stopped. Happy to say that the Davies Craig EWP^® solved all of the issues, and the car now stays at a very steady temperature in traffic.

The install was interesting, I opted to go for the full mechanical water pump delete and make my own blanking plate. Due to the routing of the alternator drive belt this also meant that the water inlet was at a challenging angle, this was solved using a thermostat housing from a hummer! The pump was placed as low as possible, and the controller installed under the dashboard, and is used to control both EWP^® and fan.

Tyre pressures and tyre temperatures are two crucial aspects of vehicle safety and performance, yet they are often overlooked by many drivers. A tyre with low pressure and increased temperature leads to reduced fuel efficiency, decreased handling, and an increased risk of accidents. Fortunately, modern technology has brought us the Tyre Pressure Monitoring System (TPMS) to help us stay informed about our tyre pressure and temperature levels. Davies Craig’s TyreGuard 400 TPMS is a very economical product which can prove to be an excellent investment in both a financial and safety perspective.  

What is TPMS?

TPMS, short for Tyre Pressure Monitoring System, is an electronic system designed to monitor both air pressure and temperature inside a vehicle's tyres. It continuously measures the tyre pressure and temperature and alerts the driver if any tyre is underinflated or indeed losing pressure, which could lead to potential safety hazards. TPMS plays a vital role in promoting road safety and prolonging tyre life by ensuring proper tyre inflation and temperature.

Davies Craig’s TyreGuard 400 TPMS uses individual pressure sensors mounted on the valve stem of each tyre to directly measure tyre pressure and temperature. Each sensor sends real-time data to the compact TyreGuard Monitor located in the vehicle’s driving compartment, which then displays the information on the led screen for the driver's convenience. The TPMS provides accurate pressure and temperature readings and can detect a gradual pressure loss.

Significance of a Davies Craig TyreGuard 400 TPMS System

1. Enhanced Safety: Correctly inflated tyres are essential for optimal vehicle handling and braking performance. TPMS alerts the driver when tyre pressure drops significantly, helping to avoid potential accidents caused by underinflated tyres.
2. Fuel Efficiency: Maintaining the correct tyre pressure improves fuel efficiency by reducing rolling resistance. With TPMS, drivers can easily ensure their tyres are appropriately inflated, thus saving fuel and money in the long run.
3. Extended Tyre Life: Overinflated or underinflated tyres wear prematurely and unevenly. TPMS keeps tyre pressure in check, leading to longer lasting and safer tyres.
4. Environmental Impact: A well-maintained vehicle with proper tyre pressures emits fewer greenhouse gases and reduces its carbon footprint. TPMS indirectly contributes to a greener environment.

Benefits of a Davies Craig TyreGuard 400 TPMS System

1. Real-time Monitoring: The TyreGuard 400 Monitor provides drivers with immediate feedback on their individual tyre pressures, allowing one to take prompt action and avoid potential tyre-related issues.
2. Easy to Use: Once installed, the Davies Craig TyreGuard 400 TPMS is hassle-free. It automatically monitors tyre pressure and temperature, eliminating the need for manual checks.
3. Cost Savings: By maintaining proper tyre pressure, TPMS helps save money on fuel, tyre replacements, and vehicle maintenance.

TPMS Maintenance Tips

1. Regularly Inspect Tyres: Despite having a Davies Craig TyreGuard 400 TPMS, it's essential to inspect your tyres visually at regular intervals for any damage to tyre walls or other abnormalities.
2. Respond to Alerts: Never ignore a TPMS warning light or alarm. If the system detects low tyre pressure or high temperature, act promptly to either inflate or repair the affected tyre(s) as required.
3. Replace Faulty Sensors: TPMS sensors can fail over time due to battery depletion or other issues. If a Sensor malfunctions, replace the battery or unscrew the sensor and replace it.

Conclusion

The Davies Craig TyreGuard 400 Tyre Pressure Monitoring System (TPMS) is a vital safety feature that helps drivers maintain correct tyre pressure and stay safe on the roads. By alerting you to potential tyre issues in real-time, TyreGuard 400 TPMS ensures optimal vehicle performance, improved fuel efficiency, and longer tyre life. Embracing this technology and following regular maintenance guidelines will not only save money but also make our roads safer and the environment cleaner for everyone. Stay informed, stay safe!

TyreGuard 400 TPMS owner Mr Graham Humphries sent in the following article on his experiences with his Davies Craig TyreGuard 400 TPMS as he and his wife Judyth are travelling in outback South Australia -

“I was driving from Blinman to Arkaroola in the northern Flinders Ranges, 183 km of dirt roads. I was travelling with another car/van combination as well as my own.

The roads had been well maintained and there were signs that recent work had been done after the previous wet weather.

We were about 90 kilometers into the drive when we came across a road crew currently grading the road. Plenty of rocks and gravel were encountered during the road works. I felt relieved that we made it to the end of work without any issues, just mud across the front of the van.

Each time we came to a cattle grid I would take it very easy as many of the grids needed attention as the grid service was above the road service. On one of the rough grids, I called our companion to say slow down it is rough. At the same time my TPMS was going crazy showing that I was losing air from a right-hand rear tyre.

I was able to pullover, and sure enough the tyre was going flat. I was glad I had the Davies Craig TyreGuard 400 TPMS as it saved the tyre from being destroyed. On reaching Arkaroola the tyre was able to have a puncture repair, cost $60.00. Should I have needed a replacement tyre I would have had to wait as they did not have my size tyre in stock and the cost was $373.00 for a new tyre.

I am thankful we made the investment in a Davies Craig TyreGuard 400 TPMS. This investment has paid for itself, not only in money but time and convenience. Who would want a TPMS kit I hear some people say? Ï know immediately when my tyre is going FLAT. A huge shout out to Davies Craig for this truly great product.”

Hand made South African 2-Stroke, 500 to take on the flats. 

An Adventure of some note! Bonneville 2024.

Occasionally we bump into some really interesting people. This time round, the enthusiastic gents from Alpha Performance Bike Tyres in Silverlakes gave us a call and invited us for a cup of coffee. “There’s an interesting project on the go as we speak, you’d better come and grab the story…”

South Africa’s Team Matjien and engineer/pilot, 67 year old Koos Zietsman plans to break the world land speed record on a South African made 498cc 2-stroke machine at Bonneville next year.

Ever heard of a partial streamlined?

You can look it up if you like, but as we understand it, it’s a fared bike and the pilots body needs to be visible from the side. 

Not sitting inside, but riding on it, as you would on a conventional motorcycle.

Yes you read that correctly, a 498cc two stroke partial Streamlined built in SA.

And then, when they remove the bodywork, he can also enter the naked class.

Engine:

There is a little bit of borrowed tech going on.

Koos and the team are using the clutch and gear arrangement from a KTM 690. Nope, not the bottom end, just some internals, minus the starter.

Everything else is being made from scratch, casings, crank, barrel, cylinder head, radiators and exhaust system.

A massive 12v Davies Craig Electric Water Pump (EWP115) sends coolant through some big radiators made by Universal Coolers to keep temperatures under wraps.

Methanol is to be supplied by a rather fierce 44ml round slide Mikuni Carburettor, complete with an electric pump and a regulator. Methanol is the fuel of choice because it’s stable, the boys have all raced with it and it helps to cool the piston.

Speaking of piston, that’s a Wiseco piston from a CR500. With an 18:1 compression ratio. “Ludicrous” in Koos’ own words.

The guys are actually3d printing a transparent barrel and cylinder head and sending water through it with tiny little balls to ensure that the flow and cooling is optimised.

Koos getting measured and mocked up for the SA built Matjien....

Chassis:

The team is building a hand made steel trellis frame from 30ml mild steel tubing. It’s easy to work with and can be welded on site.

The 17” wheels are courtesy of a CBR, as are the forks. The team has imported a set of Brembo brakes and will be manufacturing the full floating brake discs.

Rake will be at 30 degrees and they will fit a damper up front.

Out back you’ll find a custom Bilstein shock, made in the UK, just for this bike. Tyres are by Michelin, sourced by the friendly guys at Alpha Performance Tyres in Silverlakes. They are rated to 270KPH plus.

They plan to mount the hand made aluminium fuel tank and the engine as close to the centre of the bike as possible in order to keep the weight close to the rear wheel. 

It’s all about finding traction.

Bodywork will be custom made in SA 

Here’s Koos’ take on the records

“The interesting thing is that the FIM world records are WAY lower than the AMA records in this class. Maybe we bring back a brace of new records, Maybe racing grabs us by the balls and we come back with lots of experiences and memories!”

Team Matjien. 

That’s the name of the team responsible for this madcap adventures – a team that includes some very impressive credentials:

We’ve introduced you to Koos, lead engineer on the project. He will be piloting the land speed bike in August 2024.

He has roped in 2-Stroke development engineer Neels Van Niekerk. 

Joining them is Gear design engineer, Piet Van Zyl who has experience working on projects for the likes of McLaren F1 cars.

Whilst Riempies is tasked with riding that 500cc 2-stroke bike (go and see that feature in Dirt And Trail), at The Roof, he also happens to be an optronics design engineer.

Hans Fouche is an F1 Aerodynamicist. 

Fox Keet is the CAD designer for the LS498 engine for Bonneville.

The frame design engineer is Jock Pretorius who completed Roof bronze as a complete novice in 2022.

The team is rounded off by Ryan Raubenheimer who is a vehicle dynamics simulation engineer.

It’s  all been worked out really scientifically, we don’t even understand half of what they are doing to get it right, but you need to understand that these are not your average braai mechanics. 

This bike should be the real deal. We look forward to keeping you posted!

After years promoting the virtues of motorsports, public relations guru Mike Drewer has been racing for himself across the salt bed of Lake Gairdner in South Australia.

Drewer is well known among Adelaide's media and motorsport organisations for his tireless work promoting the likes of the former Clipsal 500 and the Formula One Australian Grand Prix.

Since retiring, the 70-year-old has been altering a 1964 Volkswagen Beetle for himself.

This includes "chopping" it back to make it more aerodynamic and installing a Subaru motor, fitted with a Davies Craig Electric Water Pump (EWP150) along with an esky he fills with dry ice for the turbocharger's intercooler and a Davies Craig Electric Booster Pump to assist with coolant circulation.

"The original Volkswagen Beetle had about 45 horsepower and mine has about 300 horsepower, so it's a beast of a thing," Drewer said.

"It's like driving exceptionally fast on a well-maintained dirt road with a drifting surface," he said.

"There is no traction on the salt. It's very, very hard but it has no grip, and because it's such a vast salt lake you do get side winds and things like that, so it does capture your attention."

Recently Mike and son Tom returned to the salt flats of Lake Gairdner in ‘The VW Beetle Beast’ and set a Land Speed Record for it’s class. Drewer stated, “The car has an intended speed of more than 320kph which remains the goal”.

Tom is the current record holder in the Blown Fuel Competition Coupe and Sedan - /BFCC category, recoding a speed of 145.578 (mph)

I was building our Model B engine with a Vintage Riley 4-Port Head, I realized that I had a problem finding or repairing the original Riley Water Pump. I had thought that the Riley used a Model B Water Pump (I’m smarter now), and while the Riley Water Pump looks similar, it is much larger than a Model B pump. The Riley Pump core was good but finding the parts to rebuild it would be challenging if not impossible, and I would still be using an 88-year-old water pump and nearly a 100-year-old cooling technology.

My next option was to use a modified mechanical water pump from another vehicle or use an Electric Water Pump. A drawback of a mechanical belt driven water pump is that it runs at a speed based on the engine RPM regardless of the engine temperature and cooling requirements. With a vehicle travelling at high speeds, the engine requires less cooling as ram air is assisting engine cooling, however the engine speed is higher, and the mechanical water pump is providing high coolant flow and using more engine power. In heavy traffic, or in my case, mountain driving, the engine is running lower RPM and the pump is not providing adequate coolant flow, not efficiently cooling the engine. Drag Racers and Performance guys have been using Electric Water Pumps for years to save horsepower, provide water flow to cool the engine while is not running and possibly to save weight. Based on these factors, I began reviewing the available electric water pumps.

I chose the Davies Craig Electric Water Pumps (Made in Australia, available in the US at Summit and Jegs) because they are readily available, and the electric pump does not rob any horsepower from the engine, and they provide the correct coolant flow based on engine requirements, not RPM. I used the Electric Fan because it is much safer, does to take power from the engine, and is only in operation when needed. The Davies Craig Electric Water Pumps are available in flow rates (rated in Gallons/Minute) of 21.1. 30.4, 37.2 and 39.6.

There is a chart on the Davies Craig Web Site: https://daviescraig.com.au/electric-water-pumps to help identify the correct size pump based on the engine size and application. They, and their operating Temperature for the 21.1 gal/min pump is -4 °F to 248 °F , and for all their other pumps it is -40 °F to 268 °F and pumps weigh from 2 to 2 ½ pounds. The prices for the pump alone range from $150 to $190 and for the kit with the Electronic Controller range from $340 to $400. Davies Craig EWPs are available for 12 Volt or 24 Volt operation, they are not available for 6 Volt systems.

The Davies Craig Controller is a microprocessor with a display, that is 2 9/16" wide white-on-black LCD screen displays system status (including temperature set point, pump, and fan on/off, and warnings) and doubles as a coolant temperature gauge. Single-button programming makes it quick and easy to change the target temperature at any time. You can set the target temperature in 1° C increments from 40° C to 100° C (104° F to 212° F). Davies Craig also provides Electric Fans, however any electric fan can be used if it is wired correctly. With the Digital Controller, the speed of the pump is managed by the controller which both varies the speed of the pump faster or slower and the actual run time, based on the selected target temperature. The Controller is pre-set to 185° F from the factory as the target engine coolant temperature. I reset the target temperature to 170° F for this engine. Davies Craig recommends that the setting be 9° F above the normal thermostat for the engine where the controller is installed. When the ignition switch is initially turned on, the pump will run a self-test to check the pump, and sensor connectivity, then will run at half-speed (15.2 gal/minute), at a rate of 10 seconds on, and 30 seconds off until the water temperature reaches 36° F below the set target temperature. Once that temperature is achieved, the controller will run the pump at half speed , 10 seconds on and 10 seconds off until the water temperature reaches 9° F below the targe temperature. The controller will then monitor the water temperature and adjust the pump speed from 50% to 100 % to the maintain the target temperature independent of the engine speed. The Digital Controller will operate the engine’s electric fan automatically (if installed and wired to Controller via a relay) once the engine has reached 5°F above the target temperature. Another benefit is that the Controller allows the Electric Water Pump and Electric Fan (if installed) to run after the engine is turned off for either 3 minutes or until the water temperature reaches 14°F below the target temperature to properly cool the engine.

I installed a Davies Craig EWP115 (Nylon) (Part #8930) 30.4 gallons/minute Volume Pump and Controller (EWP 115) on our Speedster which has a Model B Engine (215 cu in), an original Riley 4-Port Head, Isky cam, Electronic Ignition and two 45 DCOE Carburettors. During my installation, I used the front part of an existing Model A Cooling Pipe and hose to the radiator, then attached the hose to the pump and installed a Water Temperature Gauge Sensor to monitor the Coolant Temperature as it enters the engine. The Water Temperature Sensor for the Digital Controller (supplied with kit) is installed in the upper radiator hose to measure coolant temperature as it leaves the engine. The pump is installed in the lower radiator hose and is not hard mounted to the frame or engine. During the installation, the existing water pump will need to be removed or bypassed so it does not interfere with the new cooling system. Any thermostat will also need to be removed.

The Davies Craig Water Pumps and Kits with the Controller can be ordered from

• Jegs: (https://www.jegs.com/webapp/wcs/stores/servlet/SearchResultsPageCmd?q=davies+craig&storeId=10001&catalogId=10002&langId=-1 ) or
• Pegasus Auto Racing Supplies: (https://www.pegasusautoracing.com/group.asp?GroupID=COOLPUMP )

Pegasus also has various hose adapters that are helpful as the Davies Craig Pumps use 1 ½ inch hose for their input and output ports. I know many have used Electric Water Pumps to cool their engines, but this application was new to me, and I thought it may be helpful to others. I selected this engine cooling option because I liked the concept of using an Electric Water Pump and the Controller to regulate the water flow maintaining the correct cooling for the engine based the actual engine requirements. It also does not take any horsepower from the engine, and when an Electric Fan is used, it is much safer, and again, does not take horsepower from the engine.

After the engine had idled in traffic, the water temperature taken from the top hose, was 177° F when I shut the engine down the electric water pump and electric fan continued to operate. I monitored the temperature on the controller, and the temperature dropped about a degree every 3 seconds until the engine was cooled to a more reasonable level. I am very pleased with how the Davies Craig Water Pump and Controller is maintaining the engine temperature. I would recommend as this setup as a viable option when looking for a more modern cooling system.

*A big Thank You to Bob for putting this together. We appreciate him sharing this information as its a terrific story and will help others considering the EWP conversion.

Jason Ferraro, founder of Renner Automotive based in a cosy warehouse conversion in an inner eastern suburb of Melbourne is now applying his 30 years of experience and skill building the iconic 356 Speedsters. Jason initially built a beautiful Ford GT40 replica and has now set about recreating 21^st Century 356 Speedsters with innovative high-tech chassis, high-powered, water-cooled, fuel injected, turbocharged engines and sophisticated drivetrain systems.

The first four Renner Auto 356 Speedsters have now hit the road having gone through the rigorous ADRs, approved engineering certificates, road tested and fully legally registered for everyday road use.

The genesis of these modern-day 356 Speedsters begins right here in Melbourne, Australia! Chassis, engines, and all components come through Jason’s front door with Jason and his small team taking on the assembly work.  These classic 1956 Porsche 356A Speedster recreations have all the high-tech mechanical and electronic systems incorporated along with the wonderful ‘creature comforts’ every modern-day sports car has to offer including heated seats, air conditioning and blue-tooth technology. Ferraro holds Australian manufacturers in very high regard and is installing PWR radiators and turbo charger intercoolers in each of his cars along with Melbourne manufacturer Davies Craig supplying Thermatic Fans, the EWP115 Electric Water Pump and EBP40 Electric Booster Pump and advises: “PWR and Davies Craig are both tremendous partners in our Speedster recreations and are among the many excellent local suppliers we use.”

“We commenced the Speedster development project two years ago and all first four of these vehicles have been delivered to clients,” he says. “Components for the next four Speedsters are well on the way to completion and we plan to produce a further eight each year.

“Although we modelled and designed our vehicles to closely resemble the original item, we sell them as a Renner Auto Speedster. You can’t recreate a vehicle from scratch and name it a Porsche, and it can’t leave our workshop with Porsche badges. We can however carry out a ground-up restoration on a Porsche and this car can clearly retain all the iconic Porsche markings, badges etc, as a restored vehicle. We had an original Porsche 356 Coupe in the workshop, which we are completely modernising internally, and therefore this vehicle retained all its Porsche classic emblems.”

“Original classic Porsche Speedsters are continuing to appreciate in market value and can sell for upwards of A$700,000. 

Ferraro speaks with great enthusiasm for his business: “Renner Auto is celebrating the high point of automotive design, the period between 1950 and 1965, through the building of new cars that pay tribute to that period’s styling. These vehicles possess the styling that make them an instantly recognisable classic. By using advanced manufacturing, we build a modern chassis, engine and electrical system that makes them as advanced in technology and up to date as new vehicles.”

Ferraro adds, “I purchased the 3D printer two years ago. We 3D print prototype and select production parts using this equipment, and it has enabled us to implement OEM (original equipment manufacturer) solutions at volumes that were not previously viable. As well as the 3D printing and supporting CAD design work, I do a lot of general workshop operations, such as TIG/MIG welding and composite work.”

Dream machines - How it works at Renner: most clients are local and after scheduling an appointment, they’ll come into the workshop for a site visit. Ferraro says that some clients have even ordered their vehicle build on the spot. Several of Renner’s custom vehicle projects have seen clients investing over one million dollars to create their dream vehicle.

Ferraro uses a wall display of 3D-printed Speedster models for clients to choose the vehicle’s external colour and upholstery.

“I provide an estimated price and time frame to the client, and we often run on an open book costing model.” says Ferraro. “We use 3D scanning equipment to digitise the vehicle structure and then commence the 3D CAD design of all the vehicle systems. Then we install the modern internal components in the body, so that it resembles the original vehicle with a high-tech engine and a modern internal operating system.

The recreation of a classic vehicle takes up to 2,500 hours to build and there are usually up to six cars being built at a time. Significant time is spent on vehicle R&D and fit-out.

“Clients are involved during the build both via Zoom, regular newsletters and now face to face, post COVID-19 lockdown. They get very excited, like we do, when their custom-built vehicle is nearing completion.”

We have also completed the other metal assemblies that make up the cars and they have already been e-coated and zinc yellow plated. Every component is correctly coated so there are a few!

Radiator:

Radiators are usually manufactured from aluminium, copper, or brass. They are made up of many small diameter tubes with fins attached. Notwithstanding the materials used, radiators are basically of two types: crossflow and down-flow radiators, depending on where the tank is located. These designs allow the radiator to exchange the hot engine coolant temperature with the ambient air, with the assistance of the cooling fan thus reducing coolant temperature before it re-enters the engine.

Water Pump:

The mechanical water pump circulates the coolant from the radiator through the cylinder block, heater core, and cylinder head. Eventually, the hot engine coolant enters the radiator again and allows the radiator to cool its temperature. Mechanical water pumps are mostly driven by the engine, they can also be replaced by an Electric Water Pump (EWP®) to improve cooling performance and efficiency.  

 Thermostat:

The Thermostat is a temperature-controlled valve that only allows coolant to pass through the radiator at the manufacturer’s set/targeted temperature. When the Thermostat is closed, it redirects the coolant through a by-pass passage to recirculate the coolant through the engine which assists to bring the engine up to operating temperature more quickly. The Thermostat is a crucial component within the cooling system and should not be removed unless you are converting to a Davies Craig EWP® with a Digital Controller. Without a Thermostat or a Digital Controller installed to regulate engine temperature, the results may be low coolant temperatures, longer warm up times and can lead to overheating. 

Cooling Fan:

The performance of the radiator is heavily dependent on airflow. A Davies Craig cooling fan is used to supply airflow to the radiator when the ram-air produced by the moving vehicle is not sufficient. In modern vehicles, the cooling fans are typically electric but previously the fan was from the mechanical water pump The mechanical belt-driven fan is regularly removed and replaced with a Thematic Electric Fan to free up engine power and improve cooling performance.

When it comes to controlling Twin Electric Fans there are several options available.

You could just wire the electric fans to run all the time, however hooking them up with relays that are temperature controlled is a much better idea.

Davies Craig offers a rage of Digital Thermatic switches, like the #0444, #0445 or #0435 that will not only turn the fan on with temperature but stagger their start-up for a 2 staged cooling approach to help reduce the initial current spikes.

The #0500 offers the same 2 stage approach, however with some extra wiring you can turn this 2-stage control into 2-speed control. Giving your cooling system the ability to run both fans at a low and high speed.

The low-speed functionality allows for a further reduction in current spikes and noise compared to the 2-stage approach, while also moving air through a greater surface area. This helps to improve the overall stability and control of the temperature.

Who would have thought, that back in the ‘60’s two young Aussies Daryl Davies and Bill Craig would carve out a niche in Australian automotive aftermarket history with their innovative work developing Australian automotive and air conditioning electric fans? From very humble beginnings Davies and Craig, both of whom were qualified commercial airline pilots formed Davies, Craig Pty Ltd almost 50 years ago. This Australian owned and operated company commenced as a manufacturer in the automotive and air-conditioning condenser cooling fan industry sectors producing a range of innovative Thermatic® Electric Fans.

While much has been written about the utilization of Davies Craig’s Thermatic® Electric Fans as cooling fans fastened to the front or back of literally thousands of radiators around the world very little is known about the extensive use of Thermatic® Electric Fans in the air conditioning industry. The role played in an air conditioning system by the electric fan is vital and must offer adequate air flow to complement the heat exchange provided by the condenser which, combined with an adequate compressor and evaporator should give you cool, refreshing in the vehicle’s driver/passenger compartment.

Let us examine the air conditioning system and put forward some questions relating to the condenser, the electric fan, which, along with the evaporative cooler and compressor are the most vital A/C components.

Firstly, does the size of the condenser matter? The size of the condenser is determined by the core size of the radiator. The larger the better; fill as much of the radiator core size as possible. The evaporator absorbs the heat from inside the vehicle, and the condenser dissipates the heat. One cannot oversize a typical condenser.

Secondly, what is the general affirmation, mechanical or electric fans with air conditioning? The key is air flow, and a large electric fan or twin fans will deliver a high CFM ft³/min. Be careful when selecting an electric fan as the primary cooling fan-many just do not have the air flow capacity. One should examine the use of either Davies Craig Thermatic® Electric Fans, 14” high performance or 16” Electric Fan, mounted flush with the radiator core and set up as a ‘puller’. You will require a minimum of 2100 CFM ft³/min. of airflow. Depending on the vehicle, if you can also install a ‘pusher’ fan as a secondary fan on the condenser core, this will increase the air-conditioning performance at low speeds or idle (traffic).

Thirdly, what determines the size of an air conditioner evaporator? The amount of available space is the key factor here. You install the largest unit possible that will fit into the available space. Several factors also come into play. First and foremost is the size of the interior you are trying to cool. The second factor would be the amount of physical space behind the dash in some cases. Keep in mind that when the system is on high and working to its maximum capacity-say, on a 40°c day, it is easier to turn the A/C down than to turn it up!

Fourthly, are there any suggested engine/cooling system modifications necessary when adding air conditioning? You need to ensure you have a high-performance, high CFM ft³/min. Davies Craig Thermatic® Electric Fans, and a high volume flowing mechanical water pump or install a suitable Davies Craig Electric Water Pump and finally, at least a double row aluminium radiator. Should you select the Davies Craig Electric Water Pump be sure to opt for the Combo which offers the LCD EWP/Fan Controller, the electric adjustable thermostat. We strongly recommend the addition of a safety switch, which allows A/C system pressure to engage the electric fan/s in conjunction with and independent from engine temperature.

Do you recommend mechanical or electric fans? Electric fans are preferred because sufficient airflow must be maintained at idling or low ground speeds. Airflow supplied by a mechanical fan changes with engine rpm and can be insufficient at low-engine rpm and absorbs horsepower. With most cars and light trucks, the installation of a Davies Craig Thermatic Electric Fan/s is a great choice to free up horsepower and decrease fuel consumption. If the vehicle is to be used under "extreme" conditions, such as towing, high powered electric fans are essential. Keep in mind that the only time a fan should be necessary is when the car is at idle, low speed or standing still and an automatic Thermatic Switch should be installed. Today's Davies Craig Thermatic Electric Fans are producing more CFM ft³/min. than ever, and 2,000 CFM ft³/min. are common.

Do you recommend internal or external automatic transmission coolers? Most vehicles today are fitted with some form of transmission oil cooler. Usually the manufacturer has built in a cooler under the radiator the transmission oil cooler under the radiator module creates additional heat inside the radiator. These can prove to be inadequate given you are circulating hot transmission fluid under an already very warm radiator or installed a small core in front of the radiator. These may be adequate for normal driving conditions. An external or auxiliary Davies Craig Transmission Oil Cooler keeps unnecessary heat out of the radiator and is essential for towing as additional heat will be generated and must be compensated if you are to maintain acceptable transmission life.

What interior modifications do you recommend when adding air conditioning (tinted windows, insulation, etc.)? The single most important factor in improving the efficiency of a climate-control system is how well the vehicle is sealed and insulated. You must keep the engine heat and outside heat out of the interior of the vehicle. Keep one thing in mind-air-conditioning systems do not make cold air; they remove the heat that is in the air, Tinted windows help reflect the hot sun, assisting the air conditioner cool the vehicle more efficiently. Proper weatherstrip and door/glass seals will also help isolate the interior and lessen the load on the A/C system.

What are the most common air-conditioning installation errors? Not preparing for air conditioning in the planning stages, lack of insulation, and not allowing for appropriate space. The evaporator requires a certain amount of space and can be remotely mounted if necessary. Overcharging or undercharging the A/C system. Condensers must be mounted with the manifold tanks in a vertical orientation. Ensure you seek advice from a fully qualified specialist to assist you with this process. Under-sizing the evaporator to the vehicle-especially on finished vehicles can be an issue. Customers constantly call stating they only have so much space left, so they'll take whatever will fit. They don't like to hear that they really need to move other components around to get an evaporator large enough to do the job.

Southern Air
The biggest error is the incorrect installation of the water valve. Many people think that the water flow is from the water pump, but it's from the intake manifold or my favorite place, the cylinder head. If you use the port between numbers 7 and 5 on the head, you have one quarter of the heater hose to run and this is the hose you install the water valve on. Our electric four-way valve helps solve this problem.

The second biggest mistake is the over- or undercharging of the system.

Vintage Air
The most common installation error we deal with is improper system service.Modern 134a systems must be properly evacuated and charged to operate at maximum efficiency. Failure to properly charge a system will result in improper operating pressures, unsatisfactory duct temperature, and overall poor system performance.

The second is failure to properly install and insert the thermostat capillary tube. This results in improper coil temperature sensing by the thermostat, which leads to coil freeze-up, reduced airflow from the unit, and poor duct temperature.

Finally,

Maintaining adequate air flow at various speeds is essential and can be complex. Scoops, lips, deflectors and recessed panels can be used to improve air flow when the frontal area of a vehicle is less than ideal.

To function efficiently, the air stream on the front side of the radiator/needs to be higher than the air stream behind it. High pressure forces ram-air through the core

The next issue that requires serious attention is the fan. Engine-driven fans must have a circular shroud to be fully effective, says Davies, Craig, which states the blades should have no more than one inch in clearance to the shroud. Some mechanical fans can reach a blade stall at high RPM, causing a ‘wall’ which prevents air from passing through it. As such, Davies, Craig says the installation of a temperature-controlled, radiator mounted electric fan, in the majority of cases, as a replacement, is far more efficient.

For this reason, consideration should be given to vehicle’s use for both low speed cruising and higher speed operation to ensure the effective channeling of air to the radiator while operating in both circumstances.

Nearly all modern-day vehicles have an electric, temperature-controlled fan as standard equipment at the rear of the radiator and all modern electric fans have a standard circular shroud to maximise efficiency, explains Davies, Craig.

Pay attention the fan’s motor power (watts) and the published (CFM, Cubic ft³/min), the specific fan produces, usually the larger the electric fan the higher the CFM. Davies Craig publishes all the specifications and dimensions on its website, www.daviescraig.com.au

Some electric fans may be enclosed in a metal or nylon cowling (referred to as a shroud) which is designed to be rear radiator mounted only. Speeds of 60kmh or under, electric fans are most effective due to their total operating independence from engine revs.

Ram air intake driving above 60kmh, a fan is not as necessary, says Davies, Craig, which states the use of a cowling can be problematic as encompassing the entire rear radiator core can inhibit air flow at speed. If there is a build-up of air pressure in the fan cowling or engine compartment, air flow across the radiator can stall, causing higher engine temperatures.

For example, Davies, Craig notes that an electric fan and cowling that covers the entire core should have "trap doors", usually made of silicone, rubber or nylon, installed to assist with cooling efficiency. When cruising at low speed these trap doors will stay closed to prevent bypass. While at speed, the doors will open to allow more air flow and prevent the cowling from damming the air.

Since the engine compartment must be able to maintain pressure differential as a vehicle’s speed increases, many original equipment manufacturers install air dams or other wind deflector devices to increase the pressure at the face of the radiator and block the air from passing under the car.

Davies, Craig states an electric fan’s operation is not ‘complete’ without an appropriate Digital Thermatic Switch. Using either a Davies Craig Thermatic Switch or LCD EWP/Fan Controller will activate the electric fan/s at set/targeted temperatures.

For fifty years Davies Craig has been manufacturing Electric Thermatic^® Fans which have transformed the cooling capabilities of thousands of vehicles with their efficiency of low current draw and high air flow. Offering 8”, 9”, 10”, 11” Brushless, 12”, 14”, 14” and 16” High Performance in both 12v and 24v models these cool fans suit high powered and conventional daily drive vehicles.

So how do I find out which Davies Craig Electric Thermatic^® Fan suits my car?

Davies Craig has made this process extremely easy –

A). Jump onto our website, www.daviescraig.com.au

B). Click onto “Fan Selection Guide” in the grey banner on the top of home page. C). Place your vehicle make and model in the spaces provided or measure your radiator core dimensions (width, height and depth, (being the distance from the front of the engine to back of the radiator core).

The “Fan Selection Guide” will simply give you the appropriate fan options for your radiator to make a safe and correct choice.

1. Davies Craig Electric Thermatic^®Fans are reversible (Excl. Brushless models) which means they can be mounted either upstream or downstream as illustrated.

1. In general, one large fan may have stronger airflow than two smaller fans. Where the radiator is rectangular, or space is tight there may be no choice but to fit two smaller fans; choose the largest fan that can be accommodated in space available. The fan should be mounted offset from centre of the radiator to clear engine components when mounted in the downstream position.
2. Mount your fan directly to the radiator core and as close as possible to the hot water inlet for maximum cooling efficiency.
   Note: Fans should not be fitted on opposite sides of radiator core unless these are offset such that the airflow of one is not interfering with the airflow of the other.

Aussie Manufacturer Davies Craig Pty Ltd has been at the forefront of the automotive cooling business for almost 50 years! 

As well as developing Thermatic Electric Fans, 1996 the company turned its attention to engineering a unique rock-solid range of remote-mounted Electric Water Pumps, the company also supplies a broad range of compact Electric Booster Pumps. Some of these EBP models find their way into water-cooled turbocharger kits. There is also a growing trend to make use of the compact remote-mounted Electric Water Pumps with some inter-cooler and turbocharger applications!

There are many benefits to utilising a cooling system for a turbocharger and plumbing in an Electric Booster Pump (EBP®) or Electric Water Pump (EWP®). We all know heat, more specifically heat-soak can shorten engine, turbocharger, supercharger life and can destroy engine components.  An appropriately plumbed cooling system for your turbocharger or supercharger will provide significant benefits to performance and well worth the effort required to install an adequate cooling system.

What does engine coolant really do?

Liquid cooling improves mechanical durability and extends the life of a turbocharger. Many turbochargers are designed to be sufficiently cooled by air. Other turbochargers are specifically designed and have built-in ports. Consequently, coolant and/or oil can be pumped through the main body. How can we tell the difference between an air/oil-cooled turbo and an oil/water-cooled turbo? If the turbocharger’s housing has threaded ports on either side, at 90° from the oil inlet/outlet flanges, it is probably a liquid-cooled model. To meet durability targets a turbocharger needs coolant running through its system. The major advantage of liquid cooling is coolant can be circulated after hot engine shut down. Heat generated in the turbo housing and exhaust manifold soaks into the centre section of the turbocharger. If coolant is not plumbed through correctly, the extreme heat can potentially destroy expensive turbocharger components.

How does liquid cooling work?

The process of a liquid cooled turbocharger can be orchestrated in two ways. During normal engine operation coolant flows through the turbocharger via the mechanical water pump. However, thermal siphoning can pull some coolant through the turbo’s centre housing or it can be pumped through properly routed coolant lines. Remember, a mechanical water pump stops when the engine is shut down which means coolant effectively stops circulating. This is where an auxiliary Davies Craig Electric Water Pump and/or Electric Booster Pump can be installed to assist with the component cooling process.

Heat built up in the centre housing is transferred to the coolant via conduction just like the cooling effect that occurs in a typical water-cooled engine through the built-in coolant capillaries. If coolant within a turbocharger flows freely after absorbing heat, it will circulate through the cooling system drawing colder coolant into the turbocharger along with it. In this way, the intense heat that has soaked back into the turbo after engine shutdown is removed from the turbo components and avoiding serious damage without assistance from the engine’s mechanical water pump.

How does liquid cooling extend turbo life?

Turbochargers generate an enormous amount of heat. Heat-soak is a huge factor with turbochargers, can ‘kill’ them fast and must be brought under control after engine shut-down. Heat originates in the exhaust system and during solid use, high exhaust temperatures unload enormous quantities of heat into the exhaust manifolds, turbine housing, and turbine wheel. While designed to manage extremely high temperatures some heat will want to naturally dissipate into the less heat tolerant centre housing and associated components as they are all inter linked. While the engine is operating and oil is flowing through the turbo’s bearing system, most of the heat generated may be cooled by the oil, preventing damage to the bearings and oil seals.

Obviously after engine is shut-down oil flow stops and so does the exhaust flow through the turbine. But intense heat is still evident in the exhaust manifold and turbine housing and it must be dissipated fast. The heat can only dissipate via conduction into the turbo’s centre and the exhaust pipe or radiate into the surrounding air under the hood. A small amount of heat will be transferred naturally to the surrounding air, but the majority will transfer from the turbo housing into the centre housing since the centre housing is at a lower temperature. Additionally, some of the heat will travel from the turbine wheel into the shaft and out towards the bearing system.

During the cool down phase heat creeps via heat soak into the turbo’s centre which lifts heat into the turbo’s centre. The temperatures of the centre housing, oil seal, bearings and any oil remaining in the turbo are all elevated above the normal operating temperatures, since the oil flow is no longer available to dissipate heat. Therefore, there is a greater risk for damage to the turbo during heat soak after engine shutdown.

Does your turbo have adequate cooling?

The above has given you a basic overview of the functionality of a liquid cooled turbocharger.  We have also outlined that extreme heat is generated during operation and you can now understand the consequences of insufficient cooling. Turbocharger components can start to rapidly degrade at temperatures above 150°c (300°f) and risk permanent damage when exposed to these temperatures.

These temperatures may seem low when one examines exhaust gas temperatures which can reach 980°c (1800°f) and upwards in a high horsepower turbocharged engine. Examining liquid cooling specifically, the water jacket inside the centre of the turbocharger housing which is designed to keep all component temperatures below the limits to prevent premature failure. When coolant is not used or not plumbed correctly, component temperatures can easily go over limits and ultimately result in catastrophic turbo failure.

What is the right way to set up a water-cooled turbocharger?

Water-cooling a turbocharger does not need to be a complex project. The damaging effects of heat soak can be prevented from destroying the turbocharger through proper installation of the appropriate lines in the cooling system. The turbo’s coolant lines should be plumbed into the engine’s existing cooling system and can be teed off of the heater lines if they are still present in the vehicle and convenient. Engine coolant can be deployed without any concern. One can use 50/50 glycol/water mixture with most turbochargers. To receive the most benefit from water-cooling, the turbocharger’s centre housing should be rotated around the central axis (the shaft) so that the water ports are at an angle of approximately 20° from the horizontal. This is necessary to promote the thermal siphoning effect discussed earlier.

The coolant input (colder side, from the engine’s cooling system) should be plumbed into a port in the housing. The hotter output coolant returning to the engine’s cooling system should be plumbed into the higher port and allowed to travel “uphill” to the engine’s cooling system. Ensure there are no kinks in the return line. Select a port on the side of the turbocharger as an outlet. Coolant plumbing, colder coolant entering the low side, leading into the rotated centre housing and exiting the higher side, will reduce the formation of air pockets and allow unrestricted flow during hot engine shut down. The full benefits of a Davies Craig Electric Water Pump will be realised, and internal turbo temperatures will be minimized. The high temperatures in the centre housing can be reduced by as much as 50°c (90°f) when the centre housing is rotated to allow the hotter outlet coolant to exit from the higher port. With this brief explanation as to the benefits of adding an Electric Water Pump and circulating engine coolant through the body of any turbocharger during and after hot engine shut down should convince the sceptics of  that water cooling is a critical element to the longevity of the unit’s components.

Several differing types of coolant lines can be utilised and there are several guidelines to follow. Be sure to use hoses or lines that are rated to at least as high as 120°c (250°f) or higher in some cases. The lines or hoses should be compatible with coolant and -AN fittings are recommended for simple, leak-free installation. Steel lines or flexible lines can be used but ensure they will cope with normal engine vibration. Most automotive engines are water-cooled, which means plumbing in a water-cooled turbocharger should be straightforward.

In summary, water-cooling is an important and straight forward requirement for turbochargers that are equipped with water ports. The consequences for overheating a water-cooled turbocharger can be terminal and destructive. The reward for a thoughtfully laid-out water-cooling system in good working order is a turbocharger that will be allowed to live the longest life possible under the extremely demanding conditions that it must withstand. Putting in some thought to examine appropriate coolant connections for your turbocharger, should reward you with excellent performance and longer life in your vehicle.

The decision to build a 6-wheeler using a reversed Kombi torsion housing as the lazy axle and make a tray bed big enough to carry a beetle was relatively simple. The headaches started when Stuart decided to install a Leyland V8 engine. Engine coolant does not usually go with air-cooled VW Kombi’s and we all know why.

With an incorrect, ill-fitting radiator, a leaking mechanical water pump, discovered as soon as Stuart added coolant. The carburettor being another challenge as it was too high and came through the tray floor, not ideal!

So, a new radiator was sourced from Ferntree Gully Radiators and a new EWP115 Electric Water Pump Combo Pack from Davies Craig which Stuart upgraded to an EWP150 recently. A custom-made intake manifold with a new 45mm weber and the V8 motor was ready for action!

After a quick test run it was decided to send the motor across to Hanz at Highport Heads where he stripped it down and freshened up the internals, excellent work!

Stuart has now had his Kombi Hauler on the road for well over a year, ironed out all the bugs (no pun intended) and this lazy axle work horse is now being used for the jobs it was designed for – carrying beloved Volkswagens, Country Buggies etc. around the state and indeed the country!

The Davies Craig EWP/Fan Digital Controller is now mounted in the cabin just below the gauges and Stuart grafted the LED warning light into the dashboard. The Controller is an excellent addition as he can now read his voltage, engine temperature, fan control etc from the driver’s seat all the important options Stuart has never had the luxury see on a normal Kombi dashboard.

During the build process Stuart called on a number of good people and he would like to give a big shout out to:

• Should you leave the existing mechanical water pump in place, we would recommend you examine the Product Selection Guide for the most appropriate model.
• All models will operate in conjunction with your existing water pump.
• Ideal for racing engines as you can install an isolation switch and allow the EWP to run-on and circulate engine coolant after engine shutdown.
• The EWP will drive the coolant through the current water pump. If you are not removing your engine thermostat then we suggest you drill 2 x 5mm holes through either side of the plate to assist with circulation.
• Our recommendation - delete the mechanical water pump (remove the impeller from the water pump jacket or place a blank off plate with a 38mm inlet) and thermostat from the engine
• Full installation instructions are provided with each kit.

In our series of FAQ's answered, this is Part 1 of 7 We explain in simple terms the benefits of a Davies, Craig EWP.

Davies Craig’s remote-mounted Electric Water Pumps (EWP®) can be installed on the bottom radiator hose and can replace or will operate in situ with the existing mechanical water pump.

• Old mechanical, belt-driven water pumps run directly off the engine and sap engine power.
• As a performance or booster pump accessory that increases power sent to the drive wheels
• The engine cooling is improved with an EWP® by having a higher flow rate at idle and low engine speeds when there is little or no ram air, and when the engine is switched off.
• Improves cooling capacity and fuel economy offering a more consistent coolant flow
• Will eliminate damaging heat soak after a hot-engine shut down
• The significant improvement - the power the mechanical water pump absorbs from the engine increases as the cube of its speed – therefore when the pump speed doubles from idle, say 600 rpm to 1200 rpm, the power it absorbs increases 8 times, then another 8 times going to 2400 rpm and so on up to 10,000 rpm. This extra power and torque you are releasing by disabling the mechanical coolant pump, is delivered to the drive train.
• Electric Water Pumps can be hard wired into your vehicle’s electrical system or you may opt to use the LCD EWP/Fan Digital Controller which forms part of the EWP® Combo Kits.
• The LCD EWP®/Fan Digital Controller (Part # 8002, if ordered separately) used with either model EWP® will greatly enhance management of coolant flow, commensurate with the rising and falling of engine temperature as well as temperature controlling the operation of the electric Thermatic Fan/s.

The EBP^® have a standard, strong nylon/glass impregnated impeller driven by a brushless, long-life motor. This totally removes brush wear encountered with conventional electric motors. This design ensures an airtight seal between the pump’s impellor and volute chamber and the brushless motor. The magnetic fluidity generated is transferred through the dividing wall of the pump body, moving the pump impeller through the multi-polarised permanent magnet in the rotor assembly. The only moving part, the impeller, is floating and rotating in the coolant. The pump chamber is hermetically sealed for trouble free operation. All pumps have 19 mm (¾”) inlet and outlet. The pump’s long-life brushless motor has few moving parts, a very low current draw, high flow capacity and low noise emission. The numerous EBP^® applications include:

• Booster for car/SUV/bus heater and LPG (butane) systems
• Water-to-air intercoolers
• Circulating pump for solar applications
• Water-cooled motorcycle & Go-Kart engines
• Air/water superchargers
• Household irrigation
• Caravan/camping applications

Causes of Failure

An engine’s mechanical water pump works by being rotated at speed thanks to a belt drive or pulley system. A set of blades attached to the inside of a plate spins the coolant and sends it through the engine via internal passages and into the heat exchange, or as it’s better known, the radiator.

Presuming an engine is correctly maintained throughout, a pump should last for a couple of decades. But more likely is the chance of failure from a number of sources.

Deposit Build Up

Using straight H2O in a car’s cooling system is regarded as the absolute no-no of no-no’s. Water boils at 100 degrees Celsius and water on its own, going from cold to boiling to cold will bring out the various particles of chemicals. Mixing water and coolants can also change the fluid’s structure.

These won’t be cleared out of the cooling system unless a full flush is performed, and therefore will coagulate in the engine chambers, the tubes, and on the blades of the impeller. Visual identification can be as simple as looking at the colour of the fluid by lifting the radiator cap or looking inside the overflow bottle.

Leakage

Although gaskets, the materials used to seal mechanical parts such as the mechanical water pump onto the engine’s body, are made to be long lasting, it’s that longevity that can cause failure. In simple terms, age will eventually see the material, be in cork, or more likely a heavy paper, wear our and potentially lead to failure.

Leakage will be the most obvious sign, both on the ground, and around the join of the plate. Let alone, the fluid levels will drop, and the ability to flow and cool efficiently is diminished.

Mechanical Failure

A pump itself can fail internally, due to any number of small but crucial manufacturing issues. A spindle or shaft misalignment, the quality of the metal used, even the bearings that allow the fan and shaft to spin, can end in failure.

Although it can be hard to hear, a mechanically failing pump may make enough noise to help identify a potential issue. A visual identification may be a varying in the motion as it’s spun, with a centre section appearing to move in its own circle rather than staying put.

Another mechanical reason may be as simple as a misalignment of the pulley belt during installation. Although initially looking to be aligned correctly, time will have the effect of the belt pulling the unit more and more out of its correct place.

Engines aren’t the only things we can keep cool and Davies Craig is proud to announce a new transmission cooler kit for the Ford Ranger, Mazda BT 50, and related vehicles that are fitted with a Ford 6R80 transmission. This includes the Mustang.

What Is A Transmission Cooler?

As much as a car’s radiator, or heat exchanger, swaps heated fluid for cooler thanks to air flow, a transmission cooler does, in essence, the same thing. The difference here is that these keep the fluids, generally a type of oil, in a transmission cooler.

A gearbox is one of the hardest working parts of a car. Whether it’s a manual or an auto, it’s always spinning whilst an engine is running, and can generate some considerable temperatures. They’re mostly found in a car’s engine bay and not far from a radiator.

What causes Heat?

Everyday driving. It’s really nothing more complicated than that. From the engagement of Drive or first gear, through the range of ratios, from stop start driving to long distance country driving, a transmission is always working. More heat comes from the peak hour driving situations where cogs are engaged up and down the range, and airflow is minimal.

Heat is also caused by extra loading on the driveline, such as slow driving in sticky conditions such as mud, snow, or when towing.

Davies Craig Transmission Coolers

We offer two types of transmission coolers. For vehicles made before 1990 there is the Davies Craig ultra-cool transmission cooler. For vehicles after 1990 there is the hydra-cool, and this is also suitable for pre-1990 vehicles. The ultra-cool system works on a tube and fin design, where the fins exchange heat from the oil filled tubes. The hydra-cool is a plate and fin design, ideal for more compact spaces and for air-cooled applications.

Our New 6R80 Transmission Cooler

The Ford Ranger and Mazda BT50 are the main market targets for our new 6R80 transmission cooler. However, there is a wide range of vehicles that use the same transmission. These include the Ford Transit van from 2015 to now, the Mustang from 2011 to 2017 with the V6 or EcoBoost turbo four cylinder, and the SZ TCDi Ford Territory from 2011 to 2016. Part number 1006 is what you’ll need to look for on our website.

It’s both compact and lightweight at just 1.6 kilograms, and our transmission coolers can reduce temperatures by as much as 33 degrees Celsius, which means a longer lifespan for your transmission.

Car engines come in many sizes and have done size the first rolled off the construction line. One can head into a car showroom and be greeted with engines smaller than a bottle of soft drink, the size of a family aimed milk bottle, or bigger.

What this means is that a car’s cooling system that is designed to be a one size fits all will be good for one engine but not necessarily for another.

How It Works Without An EWP®.

Let’s take a quick look at how a mechanical system works. Whilst an engine is off, there is no cooling happening, as the radiator or heat exchanger requires fluid to be physically moved through the vertical chambers that have thin vanes attached to “exchange heat”.

When the engine is spinning it drives an impeller that’s generally mounted at the front of the engine block. That in turn is attached to a belt that is attached to the steering and alternator units. The engine’s design is such that a pair of thick rubber pipes send out and receive fluid to and from the radiator.

The downside is that once the engine has been switched off then there’s no energy being directed to create a flow. Bigger engines, or engines put under stress generate a lot of heat and therefore really do need a more efficient way of cooling.

This is where a remote-mounted EWP® or Electric Water Pump can make the difference. But which sized pump will be best for the cooling performance?

What About Performance?

This is where it gets a little technical. Davies Craig, one of the largest suppliers of after-market EWP® items, names their pumps in reference to the amount of fluid per minute. There are currently four remote-mounted electric water pumps and it’s important to note the intended usage against the flow rate per minute. There are 80 litres per minute, 115 litres per minute, 130 and 150 litres per minute. The highest flow, the EWP150®, is intended to be used in high performance or large engine applications.

Let’s say you’re driving a vehicle that has a fuel injected 350ci or 5.7L Chevrolet V8. It’s been “chipped” for better performance. A remote-mounted EWP80® is intended for engines of up to 2.0L in capacity, therefore it wouldn’t be suitable for a performance V8. Therefore, utilizing such a pump would be unsuitable and would affect the performance of the engine and its cooling system.

At the other end of the spectrum is using a remote-mounted EWP150® on a 2.0L engine. It would do a superb job but is a definitive case of overkill for the engine. That is, of course, presuming it’s a stock engine and being used for nothing other than normal driving. Remote-mount an EWP150® to a race-spec 2.0L being used in a drift situation then it would be fine.

There are typically four common Small Block Chev Overheating Problems.

Thermostat

A critical part of a car’s cooling system, particularly in cars now considered to be vintage, is the thermostat. A general design feature is of a disc in a housing, and as an engine’s mechanical heat warms the coolant in the cooling system, a material, most likely a form of wax, will liquefy and move a small cylindrical rod. This rod’s movement opens a plate that would block fluid flow through a radiator and then allow that flow to run through the vanes of the radiator and use passing air to cool.

A common SBC overheating issue is the failure of these heat activated mechanical parts which leads to a lack of coolant being circulated for heat exchange. As a rule, these parts are easily replaced and can make an instant difference in respect to fixing a SBC overheating issue.

A Davies Craig  LCD EWP®/Fan Digital Controller can be a more viable alternative. Mechanical thermostats are effectively preset to activate at one temperature. A Davies Craig LCD EWP®/Fan Digital Controller can be preset to allow flow at up to five different temperatures, meaning more flexibility and allowing a tailor-made application depending on engine size and usage.

Radiator

Depending on the capacity of the SBC, a radiator, or heat exchanger, may be of a smallish size or it could be quite broad. The size provides a certain surface area to airflow, meaning the larger the size then naturally a larger area exposed to the air. However this can also be detrimental.

A common SBC overheating issue is airflow over the radiator being blocked by a number of materials. Dirt, dust, leaves, and even insects that pass through a car’s front grille will get stuck on the vanes and thin metal plates that make up a radiator’s design. Because airflow is disrupted, and the metal itself isn’t directly in contact with the air, the temperature differential changes and the thermal efficiency decreases. As a result, a SBC overheating issue can occur.

Spray-on degreaser, a stiff brush, and a pressure hose should be sufficient to clean the radiator and allow for proper airflow. This should be enough to address this particular SBC overheating problem.

A Davies Craig Thermatic® fan can also assist. Available in different sizes and with the flexibility to be mounted on the front (to push air through) or the rear (to pull air through) a radiator, these high-efficiency units can potentially overcome any form of airflow problem for a dirty radiator.

Air to fuel mixture

This is one for the older SBC overheating problem book. Oddly enough, fuel can be considered a cooling component even though its main purpose is to be ignited and used to provide power. Older cars using “carbies” are more prone to overheating thanks to fuel and air mix matters and SBC overheating issues are no different.

Although a throttle cable moves an actuator on a carbie that releases more fuel through the venture and into the cylinders, wear and tear can see the mechanical parts incorrectly deliver fuel.

As a result, a “lean” mixture, where there isn’t enough fuel vapour in relation to the air in the cylinder, will burn hotter and can lead to cylinder damage. Think of a hot day where a hose with a mist attachment is turned on. A low flow makes little difference but a higher flow of water, making more mist, makes for a cooler localized air temperature.

This is effectively the same as what can happen inside a cylinder and overheating from an incorrect fuel to air delivery mix can be a common cause of SBC overheating issues.

Water pumps

Mechanically driven water pumps rely on the rotation of the engine to spin a pulley that rotates an impeller to move coolant. In order to move coolant efficiently the engine needs to be moving all the time and at a good rate of revolutions per minute.

This is an immediate downside in a mechanical sense as slow or stopped traffic means the engine’s rotational speed is low, and therefore moving the mechanical impeller not very much at all. Heavy traffic situations also mean little to no airflow through the radiator.

An Electric Water Pump, or EWP®, from Davies Craig is an immediate solution to the limitations of a mechanical water pump. Many SBC overheating issues can be alleviated by the fitment of an EWP®, as they can be more energy efficient by not sapping mechanical energy and can be set to activate independent of an engine’s working nature.

This means they can pump fluid independently of an engine’s revolutions and can be programmed, via a digital controller, to move coolant even after an engine has been switched off.

And because they can flow at rates of up to 150L per minute, instead of a limited flow rate from a mechanical pump, a Davies Craig EWP® (and in conjunction with an LCD EWP®/Fan Digital Controller and Thermatic® fan) is effectively a complete solution to a SBC overheating issue.

These iconic GM V8 engines are becoming the ‘transplant/crate’ engine of choice, renowned for their light weight and basic high horsepower output. The Davies Craig Electric Water Pump Header-Adaptor, coupled to one of the EWP®115, EWP®130 or EWP®150 Electric Water Pump Combo Kits frees up the parasitic power loss inherent with mechanical water pumps! This Header-Adaptor replaces the belt-driven mechanical water pump, provides more efficient coolant flow, engine warm-up and cooling, eliminates heat soak and increases engine horsepower.

For its research and development program with this latest innovation, Davies Craig purchased a Walkinshaw V8 Commodore equipped with a LS engine. The prototype of this latest version was installed along with a EWP®150 Electric Water Pump and LCD EWP®/Fan Digital Controller and rigorously road tested for a number of months. During this period the car was placed on the world-renowned Dyno Dynamics’ dynamometer at its Bayswater Headquarters and given a very solid work-out. The throttle response was the first most noticeable improvement, once the belt-driven mechanical water pump was removed. This advanced Davies Craig EWP® Header-Adaptor allows end-users to enjoy superior engine cooling technology using Davies, Craig’s Electric Water Pump (EWP®) and the LCD EWP®/Fan Controller Combo Pack.

Deleting the existing mechanical iron-age water pump from the front of the engine block also frees up valuable space, allowing for the installation of a high performance 14” or 16” Davies Craig Thermatic® electric fans!

EWP® Header-Adaptor Kit (Part #8670) consists of the following components;

• 1 – Adaptor Block
• 1 – Adaptor Back Plate  
• 2 – Adaptor Spacer
• 1 – Plate Gasket
• 4 – Spacer Gasket
• 1 – Outlet -16AN to 38mm (1½") Hose Fitting
• 1 – Inlet -12AN to 38mm (1½") Hose Fitting
• 1 – Inlet Plug -12AN
• 2 – ½” NPT 19mm (3/8”) Hose fitting  
• 1 – Heater Return fitting
• 2 – Hose Clamps
• 1 – Screw-type Belt Tensioner
• 1 – 6PK1560 Belt
• 11 – M5 Flange Bolts

ADDITONAL COMPONENTS (NOT SUPPLIED)

• Davies Craig’s EWP®150 Combo Kit, Part #8970 (recommended)
• Top/Bottom Radiator Hoses (Retained)
• Mechanical Water Pump Bolts (Retained)
• Heater Hose and Joiners (if required) 

The LCD EWP®/Fan Digital Controller mounts comfortably in the vehicle for instant visibility and access, monitoring your engine’s coolant temperature and a suite of other specific functions. These include monitoring of the EWP® and Electric Fan operations, voltage, high and low temperatures as well as diagnostic checks of the Thermal Sensor and set/targeted temperature.

This LCD EWP®/Fan Digital Controller Part #8002 is now supplied in a ‘slimmed down’ more compact version with extra solid mounting options at both the top and rear of the unit, along with the existing Velco patch. The Connector Plug is now hidden at the base of the Controller.

The LCD screen shows the present engine coolant temperature at a glance! There are also symbols to indicate EWP and Fan operation, current voltage and audible alarm if the set/targeted temperature exceeds 10c or if coolant temperature has not reached 40c within 5 mins of ignition.

When used in conjunction with a Davies Craig Electric Water Pump (EWP®) this Digital Controller allows your engine to warm up quicker as it 'pulses' the EWP® until the engine is warm and then controls the pump speed to maintain the target engine temperature. The controller will also run the pump after engine shut down to eliminate heat soak (3 mins or until the temp is 10 deg C below the target temp).

The LCD EWP®/Fan Digital Controller is factory set to 85c and can be simply set at any incremental temperature between 40c and 110c. Set the temperature you desire, normally at the manufacturer’s thermostat temperature and allow the Controller manage the rest.

The brass Thermal Sensor equipped with a ¼” NPT thread can be mounted either in the top radiator hose with the Nylon Adaptor supplied, the top of the radiator adjacent to the hot water inlet, the thermostat housing or manifold close the coolant outlet on the engine.

Coolant flow emerges as one of the last aspects of an engine’s cooling system to be addressed; but typically, this is where a majority of cooling system problems originate. A stock standard mechanical water pump has excessive impellor clearance and straight impellor blades, usually open front and back. At low RPM, this style of impellor produces insufficient coolant flow resulting in an engine overheating. At high RPM the same style impellor generates cavitation and aeration, again resulting in an overheating engine. There’s a misconception, slowing down the mechanical water pump and thus the coolant flow may result in the engine operating cooler. When, in fact, it may only reduce possible cavitation. The most efficient method to circulate engine coolant is with an electric water pump that is monitored by an electronic controller that senses coolant temperature and varies the coolant flow commensurate with engine temperature. Davies Craig’s range of Electric Water Pumps (EWP®) with highly engineered swept-blade impellors and tight clearances in the volute chamber alleviate the possibilities of cavitation as the coolant flow is more evenly increased as the engine temperature increases and so on. The heat-monitored speed control of the Davies Craig Electric Water Pump, which is managed by the LCD EWP®/Fan Digital Controller is an engine cooling solution with multiple benefits; eliminates high/low RPM during acceleration and deacceleration, offers full coolant flow after hot engine shut-down as the EWP® and an electric fan will continue to operate for at least 3 minutes or until the engine is 10c below your targeted/set temperature. This prevents heat soak and possible hot spots that may form in the cylinder heads which can have dire consequences.   

The next issue relating to air flow that requires serious attention is the fan. Engine-driven fans MUST have a circular shroud to be fully effective. The blades should have no more than 1” clearance to the shroud. Some OEM mechanical engine-driven fans can reach a blade stall at high RPM, causing a ‘wall’ that prevents air from passing through it. Hence the installation of a temperature-controlled, radiator mounted electric fan, in the majority of cases, as a replacement, is far more efficient. To function efficiently the air stream on the front side of the radiator/needs to be higher than the air stream behind it. The higher pressure is used to drive the air through the radiator core. If there’s a buildup of air pressure in the fan cowling or engine compartment, air flow across the radiator can stall, causing higher engine temperatures. For this reason, thoughtful consideration should be given to vehicle’s use for both low speed cruising and higher speed operation to ensure the effective channeling of air to the radiator while operating in both circumstances.

Nearly all modern-day vehicles have an electric, temperature-controlled fan installed as standard equipment at the rear of the radiator. All modern electric fans are supplied with a standard circular shroud to maximise efficiency. Attention should be given to the power (watts) of the fan motor and the published (CFM, Cubic ft³/min), wind force the specific fan produces, usually the larger the electric fan the higher the CFM. Australian manufacturer, Davies Craig publishs all the specifications and dimensions of the entire range of 12v & 24v Thermatic Fans and Thermatic Switches on their website, www.daviescraig.com.au

Some electric fan models may be enclosed in a metal or nylon cowling (sometimes referred to in some circles as a shroud) which is purposefully designed to be mounted on the rear of the radiator, only. While driving at speeds of 60kmh or under, electric fans are most effective due to their total operating independence from engine revs. With a clear air intake in front of the radiator driving above 60kmh a fan is not as necessary. The use of a cowling can be problematic as encompassing the entire rear radiator core can inhibit air flow at speed. If there is a build-up of air pressure in the fan cowling or engine compartment, air flow across the radiator can stall, causing higher engine temperatures.

For example, an electric fan and cowling that covers the entire core should have "trap doors", usually made of silicone, rubber or nylon, installed to assist with cooling efficiency. When cruising at low speed these trap doors will stay closed to prevent bypass. While at speed, the doors will open to allow more air flow and prevent the cowling from damming the air. Since the engine compartment must be able to maintain pressure differential as a vehicle’s speed increases, many original equipment manufacturers install air dams or other wind deflector devices to increase the pressure at the face of the radiator and block the air from passing under the car.

In conclusion, an electric fan’s operation is NOT ‘complete’ without an appropriate Digital Thermatic Switch. It is vital the electric fan is automatically activated when the engine temperature reaches the manufacturer’s thermostat temperature and the heat transfer of coolant leaves the engine to the radiator or in case one is using a Davies Craig LCD EWP®/Fan Controller, the electric fan/s will activate at +3c above your set/targeted temperature which again, should be set at the OEM’s thermostat temperature. There are too many stories of ‘cooked’ engines when the vehicle owner forgot to activate the manual override switch. Remember the temperature gauge in the vehicle is a ‘guide only’ and by the time this information has made it to the gauge the engine temperature may have risen to a critical level.

Chris has fitted a Davies Craig Electric Water Pump (EWP®) and a Thermatic® Fan specifically to counteract the older British cars propensity for serious overheating in stationary traffic. Although he doesn’t specify which model EWP®, Chris does say it’s a larger flow model in order to cope with the flow demands of the larger engine. And as a customer service offering for those that seek out their specialist services, Chris always recommends that the owner should fit a Davies Craig EWP® for exactly the same reason. Chris sees it as insurance, that peace of mind to ensure that there are no overheating problems.

The Geelong Revival is a huge motoring event that brings car watchers and car lovers alike to the city of Geelong once a year. But it’s not just a motorshow, it’s a chance for companies and car enthusiasts to share their stories.

Davies Craig had a strong presence at this year’s event and took time out to speak to some of the people about their cars.

Greg Bass is the owner of tuning house, Top Torque Performance. Greg was at the Geelong Revival with the company’s 2004 Subaru WRX STI. The company campaigns the car in the Australian tarmac rally championship, an event that tests cars to the limits and requires some serious cooling.

There’s a Hi-Po 2.0L turbo four under the bonnet that pumps 380kW to all four paws via a six speed sequential gearbox. Greg specified a Davies Craig Electric Water Pump (EWP®) and Thermatic® Fan for this powerhouse machine and says the extra control over the flow through the engine has been of real benefit. Greg also enjoys the ability to have the system flow at his discretion and says it’s been completely trouble free since the combination was installed. So successful has been the install that they’ve decided to fit the exact same equipment to another of their cars to ensure it, too, can maintain top performance and withstand engine heating..

Australian Jake “Driftsquid” Jones is one of those and showcases his immense talent regularly around the country. Jones recognises the strain that the engine and cooling system is put under during a full power drift session and he’s called upon Davies Craig to be the main cooling suppliers for his RB26 powered RBM3.

Strengthened internally, the engine has a massive redline, and can spin to 10,000rpm. Jones says that the engine is constantly near that number during a session and naturally needs a solid source of cooling. In this case, he’s specified a Davies Craig EWP®150. Capable of flowing 150 litres of fluid per minute, this is the highest flow EWP® we have in the range and is intended for use in high stress environments, just like that which Jones works in.

Jones points out that the engine still looks like the factory fitted water pump is still on the engine but clarifies that it has actually been disassembled, and , the pulley that attached to the pump remains  as part of the belt system that spins the car’s alternator. It also means, he says, that because it’s the standard belt he can be assured of availability almost anywhere and not rely on a custom set.

Jones then points out that the thermostat is removed due to the fact the EWP®’s own sensor system takes over temperature monitoring duties. The radiator for the engine in the RBM3 is located not up front near the engine, but at the back of the car, inside the boot.

It’s here that Jones showcases the clever design of the radiator’s air intake, with the roofline funneling air down where a section of the rear window has been removed and replaced with a custom design channel that directs air into the finned alloy radiator. On the underside of the radiator is a pair of electric fans complete with shroud to maximize air flow. On the driver’s side and housed neatly in the rear quarter is the EWP®150.

Jones mentions the design specification of the EWP®, in that the bottom hose of the radiator plugs into the front centre section of the EWP® and the outlet runs back to the engine. He’s used high strength alloy connector and braided hose for strength and durability. He mentions the accessories that are included in the EWP®’s kit allow easy fitment of the hoses and connectors.

Being a drift car driver means he’s all too aware of heat soak. Jones points out that the electronics of the system allow him to manually engage the cooling flow, but also allows programming of the EWP® to continue flowing for up to three minutes after the engine’s been shutdown, or when the fluid reaches a preset temperature. The benefit, says Jones, is that it really minimises potential engine damage.

Jones unboxes an EWP®150 kit, part number 8970, and takes delight in pointing out that the kit includes everything that should be required to install the EWP®. That includes the digital controller, wiring loom, temperature sensor for the top radiator hose, and a comprehensive set of instructions for the kit.

Jones wraps his excellent presentation with a surprise gift for his viewers.

Davies Craig are offering a discount of 35% for viewers with a special discount code of ‘JakeChristmas2019’ via the daviescraig.com.au which is available until December 22^nd, 2019.

The event sees vintage aircraft take to the skies, a range of automotive suppliers and restorers showcasing their wares, plus a child friendly transporter in the form of The Little Blue Train. There’s also a broad range of food and beverage sellers to help create a well-rounded and entertaining event.

The centerpiece of the Revival is the quarter mile sprint and the vehicles that compete are of a very diverse range. The winner of Sunday’s Classic Top ten Shootout was Noel Inman. The car? A 5.0L powered Model T Ford. 2^nd place was a Camaro, 3^rd a 1965 Mustang, and 4^th was a 1956 FE Holden. The grunt came courtesy of a 5.8L V8…

Davies Craig Sales & Marketing Manager, John Benson, was also at full throttle as he showcased his very own Porsche 550s Spyder replica. Not only is John’s Porsche 550s Spyder stunning to look at, but this James Dean inspired replica also delivers. It packs a punch with a 2.5 litre horizontally opposed, water cooled, fuel injected boxer engine, and John has fitted an alloy Davies Craig EWP®130 Electric Water Pump Combo kit, and a 14” HP Thermatic® Fan coupled to a front-mounted alloy radiator to keep it running cool. John also participated in the ¼ mile sprint activities on Sunday and finished a creditable second in class, zooming down the strip in a creditable 13.80 secs.

Having the Spyder on show gave the Davies Craig team the opportunity to showcase just how the Davies Craig LCD EWP® & Fan Digital Controller operating in tandem with the Electric Water Pump and Thermatic® Fan works effectively and efficiently to modulate engine temperate to potential car enthusiasts.

“It’s with these sorts of vehicles that owners look to us for specialist cooling advise to meet their cooling needs.  We’re able to discuss the product range we have and recommend the right products for their individual car or build project.” Explained John.

“We’re also excited this year to take the opportunity to do some video interviews with owners and talk about their cars and the equipment they’ve used.

This gives us real time, real world, feedback on how our customers have implemented and installed their choices of EWP®s, fans, digital controllers and other products from our vast range. This in turn allows us to discuss options that might further improve their setup; perhaps a bigger fan, a newer controller, or a better choice of EWP® for the kind of engine and driving being done.” John said.

Davies Craig loves events such as the Geelong Revival as we showcase our range by having a display stand. This allows people that may not be aware of our products to see and feel our EWPs®, spin the electric fans, and ask our experienced staff questions.

Big Block Chevy engines are known for their easy going, low stressed nature, producing prodigious amounts of torque at the same or lower revs than the extremely popular Small Block Chev engine. The Big Block Chevy engine is heavier, larger and produces longer strokes compared the Small Block engine. This has made the BBC an attractive engine for Hot Rodders and muscle car enthusiasts alike.

Davies Craig Electric Water Pump for Big Block Chevys

Davies Craig has specifically developed an Electric Water Pump, or EWP®, for the BBC engines. The standard water pump on BBC engine is  a belt driven unit, and the pump is located at the front centre of the block. However, there is a separate kit for the BBC, as the fitment is different.

The Davies Craig Adaptor Kit for a Big Block Chevy engine is listed as part number #8621 and #8620 (the difference being the color of silicon adapter hose). This will require a separate Electric Water Pump (EWP®).

The Davies Craig Chev Big Block EWP® Adaptor Kit

Listed as part number #8621 the kit comprises hose clamps, a silicon-based hose, o-rings, adaptor parts, and more, in order to fit a Davies Craig EWP® to a BBC.

Again, just like the SBC (Small Block Chevy) it’s recommended to utilize either the EWP®115 as the minimum, or the EWP®150 with an LCD EWP® & Fan Digital Controller plus a single or double set of Davies Craig Thermatic® Electric Fans. The EWP® and number of Thermatic® Electric Fans will depend on the location chosen inside the engine bay and the application the BBC is being used for. If the BBC is something over 400ci, it’s best to select the EWP®150, with its 150 litres per minute flow ability.

Davies Craig supply the EWP®115 and EWP®150 Electric Water Pumps with 38mm OD (outside diameter) inlet and outlet ports. There is flexibility too with the alloy versions of these pumps having internal threads milled in. These are of an AN16 standard for common use in internal threading.

If your radiator hoses have a larger inside diameter (ID), we can supply 3mm and 6mm (part no. 8510/8511) Rubber Adaptor Sleeves to suit.

The installation procedures will be very similar to those as provided for the SBC. The kits come with a comprehensive installation sheet and our website also has tips and hints.

Davies Craig BBC Header Adaptor Kit.

The BBC Header Adapter Kit (Chev Big Block EWP Adaptor) is almost identical to the SBC kit, but tailored for Big Block Chevy engines. This is part number #8620 and again is designed to route cooling liquid through the manifold system of the BBC. This requires the removal of the mechanically driven water pump, and installation of a suitable Davies Craig EWP®. Again, depending on intended usage either the EWP®115 or EWP®150 should be sourced, along with our digital controllers and Thermatic® Electric Fans.

The SBF has resulted in what is now recognized as a somewhat iconic engine, however, some older engine blocks may have cooling issues and may require a full block clean.

Davies Craig Electric Water Pump (EWP®) for SBF 302.

Davies Craig supply a Header Adaptor Kit for the 302ci Windsor Ford engine. Part number #8640 includes a replacement plate for the mechanical water pump, a replacement gasket, screws, elbow adapter and O-ring, plus our comprehensive instruction sheet.

It’s suitable for the 221ci, 260ci, 289ci, and 351ci Windsor block.

It’s recommended that a Davies Craig Thermatic® Electric Fan and LCD EWP® & Fan Digital Controller also be installed for a complete cooling system upgrade.

When it comes to our EWP® range, smaller capacity engines would suit our EWP^®80, however to be completely safe, our EWP^®115, EWP^®130  or EWP^®150 will be ideal. Although the EWP150® may seem like overkill, the fact that it will flow 150 litres per minute means that the risk of overheating is drastically reduced.

Electric Water Pump (EWP®) Installation for Ford 302

As always, safety is paramount when working with mechanical and electrical parts. See the steps below for an overview of how to install an Electric Water Pump on a small block Ford.

• Disconnect one terminal from the battery (if feasible as this depends on the vehicle), and ensure the work area is a clean, and dry, location.
• Disconnect the hoses connected to the radiator and drain the fluid into a clean receptacle. This may allow it to be reused, depending on its quality. Make sure the hoses are kept, as some of the hoses can be reused.
• Remove the drive belt as this allows access to the mechanical water pump’s bolts to remove the plate. Keep the bolts and give them a clean. It’s here that a good clean of the face where the pump was located needs to be performed.
• Put the gasket onto the clean face and bolt the plate back in. Don’t forget a bit of adhesive and sealant will help ensure no leakage.
• Install the supplied adaptors, clamps, and o-ring on the plate as per the included instruction sheet.
• Then install the temperature sensor - this is the part that takes over from the thermostat. If your engine has a heater return outlet, then an adapter will be required and this screws into the front of the EWP®.
• Cut and fit the radiator hoses to the radiator, EWP®, and plate as required. The temperature sensor should connect to the upper radiator hose and should be inserted between two sections.
• From here, mount your chosen Davies Craig Thermatic® Electric fan.
• Connect your digital controller as per the instruction sheets.
• Check out all mounting points for a quick tighten, refill the radiator and reconnect the battery.

What Is a Mini Cooper?

Travel back to the early 1960s and the Mini has quickly become a cult car.  Designed by Sir Alex Issigonis, it became famous for its ‘bigger on the inside than it looks’ space, its funky good looks, and in Cooper Works specification, a lot of muscle for a small four cylinder engine car.

BMW bought the name and in 2000 relaunched the Mini range. This includes the John Cooper Works GP Kit.

                             This Mini Cooper S, AKA ‘The Bomber’ utilizes a Davies Craig EWP®150

Electric Water Pump (EWP®) for a Mini Cooper

Although not a common installation, the EWP®80 would be the preferred Electric Water Pump for a Mini Cooper. For a range of engines that have a small capacity, the Davies Craig EWP®80 becomes the ideal choice to take over from the existing engine driven water pump. There have also been several ‘pocket rocket’ Minis which have been fitted with an EWP®150, though fitting these might be a little trickier due to space limitations.

Issues known with original Mini equipment include the temperature sensor. Made of a plastic material, the sensors are known to wear and fail. Our temperature sensor kit, part number #0409 would make a perfect replacement for the OEM (original equipment manufacturer) part.

The kit includes a sensor, compression fittings, and clamps.  The EWP80® itself can be purchased on its own, or more conveniently with a complete kit to make installation more feasible.

Due to the limited available space inside a Mini Cooper’s engine bay, some specialist work may be required to ensure a perfect fit. A benefit of using a Davies Craig EWP80® is its small size and light weight. At just 900 grams and made from super strong nylon, it’s a durable and lightweight addition to your Mini Cooper’s cooling system.

           Not a Mini Cooper, Still a Mini! Ollie Scull’s 1985 Mini Mayfair is equipped with a Davies Craig EWP®150.

What Is the Chevrolet LS?

Chevrolet has a long and solid history of developing V8 engines. They come in what are known as small and big block, which refers to their capacities. The LS name goes back to 1995, when Chevrolet re-engineered their long running small blocks.

Built in a 90 degree V8 configuration, the performance oriented LS engines are built using aluminium as the main material, whereas the “normal” engines are iron blocks.

General Motors defines the history of the LS as Generation 3, Generation 4 and Generation 5 as LT, or Gen III, Gen IV, and Gen V.

There is little in common with the previous versions of the Chevy V8. Just the rod bearings, lifters, and bore spacing are carried over from the preceding versions.

Davies Craig EWP® For LS Series Engines.

Davies Craig has specifically developed an Electric Water Pump, or EWP®, for the Chevrolet LS Series  engines.. The standard water pump on an LS engine is a belt driven unit, and the pump is located at the front centre of the block.

Our solution for the Chevy LS engine is a full kit of parts that simply needs to have an EWP® added. The kit itself provides the full range of additional parts required to fit a Davies Craig EWP® plus an installation will utilize some of the original equipment.

The Davies Craig LS Header Adaptor Kit Installation.

Listed as part number #8650, the kit includes alloy inlet adaptors, hose clamps, silicon hoses and more. What is required is an EWP®, and it’s recommended to be the EWP®115 as the minimum, with the EWP®150 the preferred choice, plus a LCD EWP® & Fan Digital Controller, which becomes your new electronic ‘Thermostat’. As always, safety is paramount when working with mechanical and electrical parts. Disconnect the positive terminal from the battery (if feasible as this depends on the vehicle), and ensure the work area is a clean, and dry, location.

Drain the coolant from the radiator into a clean receptacle. Then disconnect the radiator hoses. The LCD EWP® & Fan Digital Controller will take over the duties of the thermostat.

Make sure the hoses are kept, as some of the hoses can be reused. Remove the drive belt and this allows access to the mechanical water pump’s bolts. It’s here that a good clean of the face where the pump was located needs to be performed.

Install the two Alloy Adaptors supplied, clamps, and T-joint as per the included instruction sheet.  Then install the Thermal Temperature Sensor..

A Y-shaped hose is included which connects to the Alloy Adaptors. It’s now that your chosen EWP® should be attached; it may also have required some preassembly and should go into the “bottom” of the Y.

We’re on our way to finishing the installation. Reattach the belt, check all the clamps for the right tension, trim the top and bottom radiator hoses to length, and reattach. Refill with anti-boil-anti-freeze coolant ensuring all the air has been expelled from the cooling system. Reattach the battery terminal removed earlier.

Davies Craig also recommends a Thermatic Electric Fan to complement the EWP® and LS Adaptor Kit. The most suitable fan can be found on the Davies Craig website.

Davies Craig has plenty of assistance and a broad product range when it comes to supplying Chev LS engines with an EWP® and accessories.

Factory equipment in BMWs is generally of a very high standard. In fact, a high proportion of BMW engines utilise a bespoke electric water pump. There are some recorded instances however, of OEM fitment equipment failing due to the internal materials collapsing.

Most applications of a Davies Craig EWP® and accessories being attached to BMW engines or BMW bodied cars are in motorsport areas.  Norwegian born drift racer Joachim Waagaard campaigns a BMW M4 fitted with a Chev LS2 engine pumping 600 horsepower and cooled by a Davies Craig EWP®150.

Seattle based J. Houser rebuilt the front end of his BMW 2002 after a minor collision. He kept the stock radiator but upgraded his cooling to a Davies Craig EWP® and LCD EWP® & Fan Digital Controller for reliability. In his own words: “The beauty of the controller is that I can set the engine temp to whatever i want and it stays rock steady, whether it be mid-winter or mid-summer.”

Peter Carrol, a BMW Club instructor, also uses and recommends Davies Craig EWP®s. He says: “On the S54s, (an engine built between 2000 to 2006) we remove the water pump impeller and ring. Then we shim the thermostat open. This flows so much better and the resulting cooling is much better. We don't have a problem with the engine not coming up to temperature. S54s run pretty hot. After warm-up water is usually around 88-90C.

The recommended EWP® for the S54, suggests Peter, is the EWP®150 and a suitable LCD EWP® & Fan  Digital Controller

As an option to provide cooling for a new BMW, Davies Craig’s range of EWPs®, Thermatic fans, and even OEM replacement fan clutches for their mechanical fans can be found on our website.

Potential Issues with BMW

Reliability is a word normally associated with BMW cars and parts. But, like anything mechanical, there can be some issues.

Engines and radiators (heat exchangers) utilise a fluid called coolant. It’s a brew of liquids and chemicals that is designed to transfer heat away from the engine at temperatures above the boiling point of water. However, it’s very nature can mean it finds its way through flaws in engine blocks or via engines that have failing gaskets. This means that the engine, radiator, and water pump could be subject to impending failure and won’t be working as efficiently. The telltale signs are greenish hued streaks on the ground underneath the engine.

As most BMWs use electric water pumps already, the signs to look out for here are unusual noises and an increase of temperature at standstill. Most electric water pumps in the BMW range have plastic internals. General wear, tear, and heat related fatigue can see the plastics break and shatter. This, naturally, can lead to those parts making their way into the internals of an engine for an expensive rebuild as a result.

Benefits of a Davies Craig Electric Water Pump (EWP®) for BMW.

It’s been found that these the regular water pumps tend to fail upwards of the 100,000 kilometre mark. As a result, the change to a Davies Craig EWP® and associated products could be a life saver for the BMW’s engine and cooling system.

By fitting a brand-new Davies Craig EWP® system, this immediately takes a potential OEM (Original Equipment Manufacturer) part out of the equation. Some BMWs can be notoriously expensive to service and repair, especially in the engine bay, hence fitting one of our EWPs and digital controllers can save the hit to the bank balance.

And because we offer a range of EWP®s with different flow rates from 80 litres to 150 litres per minute, we can potentially provide a better working system than that originally fitted to your BMW.

Moving air across the vanes of a radiator, or heat exchanger, is crucial to keeping an engine as cool as possible.

Vehicles come off the production line fitted with a belt driven fan, the belt being attached to pulleys which are attached to the engine. Often, these designs have a mechanically driven fan attached to the nose of the mechanically driven water pump and the fan has a type of clutch that allows the fan to speed up or spin down and come to a stop by itself.

For the general market, this setup proves sufficient for standard vehicle use on standard roads.  However, as a mechanical fan runs off the engine, its performance is reliant on the engine running above a specified RPM, with no excess stress in its environment.

When outside factors that create a high stress environment are introduced, a typical mechanical fan does not sufficiently maintain a suitable engine temperature.

Other factors of a mechanical fan that cannot compete with the efficiency and performance of a Davies Craig Thermatic® Fan include: they are less energy efficient, they are often less aerodynamic due to the design of the fan blade, they are often placed in an unsuitable location in respect to the radiator, and they are often lacking a shroud to assist in directing airflow.

A Davies Craig Thermatic ® fan runs off your car’s electrical system making it more energy efficient and reliable than a standard issue mechanical fan.

Benefits of a Thermatic® Fan

There are multiple benefits of fitting a Davies Craig Thermatic Fan® to your engine. As describe above, they run on the electrical system meaning their function is not restricted to when the engine is running and are more energy efficient.

Furthermore, when you have a requirement for greater cooling capacity, two fans can be fitted in an upstream/downstream configuration. In this situation, we recommend installing one fan in front of the radiator on the driver’s side of the car (headlight side), and the other diagonally opposite on the back of the radiator, on the passenger’s side of the car (engine bay side). 

To further enhance the functionality and usability of the Thermatic Fan®, a Davies Craig LCD EWP/Fan Digital Controller (8001) can be fitted to allow greater control over the fan’s activity. The controller can be set to run the fan at all times, only when needed, and/or to run on after the ignition is switched off.

Fitting a Thermatic® Fan

When it comes to finding and fitting the right electric fan or fans to suit your car, there are a couple of areas to look at. The thickness of the radiator is the first aspect to consider. A thicker radiator requires a greater airflow through the vanes.

Secondly, the shape of radiator itself must be considered. As a rule, one large electric fan will do as good, or a better job than two smaller ones. However, a wider than taller radiator may negate a single fan fitment, therefore two smaller diameter fans can be mounted side by side. It’s here that the research teams have provided a unique and groundbreaking solution. Davies Craig Thermatic® fans for cars are built to have reversible blades and hubs.

Davies Craig Fan Design

The design of the Davies Craig Thermatic® fan blades supersedes that of the standard fan in two ways. The blades are shaped to be both more aerodynamically efficient (reducing drag) and less likely to vibrate and cause supersonic shock. Supersonic shock is where the ends of the blades reach a velocity approaching the speed of sound, and therefore, not unlike many WW2 fighter planes that crashed due to the phenomenon not being understood, shake uncontrollably.

The blade design we use has them straight out from the hub, and by curving the struts that are inside the shroud housing, airflow is increased and airflow noise is decreased. Also, when it comes to the tips of the blades, we’ve looked at the aerospace industry and the work put into the winglets on the ends of the wings on aircraft. Those stubby little winglets decrease air turbulence and balance air pressure as the tips rotate past the shroud.

And because we know not every engine is the same, Davies Craig offers six different fan diameters, from 8 inches to a large 16 inches. This means there will be at least one or two electric fans that will be ideal for your engine and radiator size. Couple this with our extensive range of digital controllers and there is a fan & controller package perfect for your vehicle that will far outperform your existing mechanically driven package.

As a rule, they’ve turned out to be either  lighter and more fuel efficient, or, when placed into cars for motorsport purposes, the SBC gets a harder workout.

As a result, a good cooling system is needed and Davies Craig has just the right product to help keep an SBC running at an optimal temperature.

Which Electric Water Pump Should I Use For an SBC Engine?

After some solid research, it seems our EWP®150 has become the Electric Water Pump, or EWP, of choice. Some have chosen, for their specific purposes, the EWP®115, with 115 litres of flow per minute. Unsurprisingly, many installers have also chosen to use one of our digital controllers.

This makes perfect sense, and makes the pairing an ideal choice for an SBC electric water pump installation. Their relatively compact design and basic structure allows for comparatively simple swaps, and then makes installation of an EWP® and controller just as easy.

When Should You Use an Electric Water Pump For an SBC Engine?

Some SBCs were known to have some flow issues when it came to cooling. By bolting in an EWP®150, with a flow rate of up to 150 litres of coolant per minute, these issues are easily tamed. A benefit of using a Davies Craig EWP® is the fact the pump can be bought with a kit that covers all aspects of installation. Then there’s the weight reduction, with an EWP®150 weighing less than 1.2 kilos.

Drivers can choose to use an EWP® on its own to replace the mechanical water pump built into the SBC.  Kits and parts allow the connections on the engine’s mechanical pump to be bypassed and blocked off, ensuring flowing is via the EWP® solely. Due to the flexibility of the packaging, an EWP® can then be mounted anywhere between the radiator and engine. Depending on the engine bay of the car the SBC is going into, the EWP® can be left free between the hoses, or mounted into a chassis rail, or perhaps an internal wheel arch.

Or, an owner can choose an all-in-one adaptor kit, such as our Header Adaptor for Small Block Chevs as an ideal accessory to an EWP® on its own. Here, the kit supplies the clamps, pipe, and bolt-on adaptors for the Small Block Chev, which means all that is required is a couple of spanners, a screwdriver or two, and of course, a Davies Craig Electric Water Pump.

Controlling Electric Water Pump in SBC Engine

By using a digital controller for a Davies Craig Electric Water Pump, a driver can then set the controller to continue flowing coolant through an SBC after the engine has been powered down. This is ideal for motorsport applications.

A controller can also set an EWP® and a Davies Craig thermatic fan to run from a preset temperature, such as those occurring during city stop-start traffic. With most Small Block Chevs running a belt driven fan, it’s highly recommended that a Davies Craig Thermatic fan be installed to replace that.

An EWP®150 from Davies Craig has been engineered to cope with power variances, meaning it will cope with voltage as low as 3V or a high 15V. It’s also engineered to cope with huge temperature changes. This means a drifter in Norway can start their car in conditions as low as -40Celcius and deal with heat in the heart of a desert up to 130Celcius. And being made of powder coated aluminuim, it’s strong, lightweight, and easy to clean. It’s also available to buy on its own, or in two kits, one of which includes the digital controller.

Davies Craig has plenty of assistance and a broad product range when it comes to supplying SBC engines with an EWP® and accessories.

One of its’ convenient benefits is that it can be installed to bypass the engine’s own built in mechanical pump without the need to remove the mechanical pump in the first place. Best bought as one of the many kits available from Davies Craig, the procedure to install the EWP® and bypass the mechanical pump becomes easy to do.

A bit of prior planning will be required. Head to our distributor page to find your local store to purchase  the relevant kit  for your particular car’s cooling system.

As always, the car should be in a parked position and the ignition off. If possible, the battery should be temporarily disconnected. Depending on the layout of your car’s engine, the bolts holding the mechanical pump should be loosened to allow the drive belts to be removed. As there will be coolant being released from the pump being removed, a bucket of some sort should be placed directly underneath to assist in minimising wastage and mess.

The pump may be “welded” to the engine due to age and heat soak. A thin implement such as a flat head screwdriver may  need to be inserted between the pump housing and engine, to gently  lever off the existing pump housing. All care should be taken here.

Remove and disengage the mechanical water pump’s belt. Depending on the design of the mechanical pump, there may be different ways of disengaging the impeller. This may need some extra bolts being released to remove the impeller.

The pump housing should have the pulley for the belts, once the housing is reinstalled and tightened down, the belts can be put back into place. The housing will have inlet and outlet ports. These will need to be blanked off to ensure the EWP® is the only source of moving fluid through the system.

Install the EWP® as per the instructions provided in the pack, and if the battery had been  disconnected at the start of the process, now reconnect. Start the car once everything has been cleared and cleaned, and check for leaks.

Our final instalment will be: How to install the EWP® whilst removing the mechanical water pump.

When used as an auxiliary to your engine’s standard issue mechanical water pump, a Davies Craig Electric Water Pump will increase the flow of coolant through your engine, particularly when operating under high stress conditions or elevated temperatures. In fact, both the existing belt driven mechanical pump and the Davies Craig EWP® will pump through each other when running alone and they will boost each other when ruining at the same time.

Beneficially, when running together they will actually pump more than the sum of each pumping alone.  

To cater for the variety of engine capacities and the varying demands different engines must withstand, Davies Craig HAS developed 4 sizes within ITS EWP® range; the EWP80, EWP115, EW130 and EWP150. Refer to the table below for sizing and suitability information.

Installation consists of placing the EWP® in the preferred operating position where it cut into the lower radiator hose AND is wired directly to the battery. A section of approximately three to four inches, depending on your setup, can be cut from the hose and the EWP inserted into the gap. Securely clamp the EWP®’s inlet to one of the remaining sections or hose, and the outlet to the other.

From here, a temperature sensor or thermal switch can be inserted into the upper hose connection at the radiator. This allows the EWP TO OPERATE WHEN TH EENGINE TEMP REACHES YOUR CHOSEN CUT IN POINT WHILE THE mechanical pump continues TO OPERATE NORMALLY..

This adds increased capacity and effectiveness to your engine’s cooling system. While driving at speed, the mechanical pump will be the primary fluid mover using energy from the engine belt, but at idle the engine’s speed drops dramatically SO THAT mechanical pump  flow  IS just  15 to 20 litres per minute.

With the Davies Craig EWP® fitted and operating, when the coolant temperature reaches a pre-set limit, the EWP® is engaged and supplements the mechanical pump with an additional flow of 80 to 150 litres per minute .

Furthermore, if the EWP® is wired directly to the battery, when you turn off a hot engine, the EWP®  will continue to run and wash out heat soak, cooling down the engine evenly until the engine temperature reaches the pre-set temperature less 4c.  After the EWP® turns off, the heat may still transfer and the EWP® will turn on for another shorter period and run for about 30 SECONDS at a rate of 6/9 amps, which draws very little from on the battery.

Our next instalment will be: How to install the EWP® whilst keeping the disengaged mechanical pump in place.

Both the existing belt-driven mechanical pump and the EWP® will pump through each other when running alone and they will boost each other when ruining at the same time. In fact, when running together they will pump more than the sum of each pumping alone.

You set the temp switch to the temp below which you want the engine to run. If the temp goes above that set temp, the EWP® will turn on and run until the engine temp is 4 degrees c cooler and then switch off.

When the engine is idling the existing belt-driven pump may be producing 15 to 20 l/min coolant flow rate.  The EWP® will kick in with another 80 to 150  l/min.

When you turn off a hot engine, the heat in the exhaust manifold passes to the block and the engine temperature actually increases after you turn off the engine. More heat goes into the side where the exhaust manifold is located. If the head is alloy and the block iron, they will expand at different rates. In any case, the head will tend to twist to accommodate the difference in temperatures, and then the head or the head gasket will be damaged.

If the EWP® is wired direct to the battery, when you turn off a hot engine, the electric water pump will continue to run and wash out heat soak and cool down the engine evenly, until the engine temp reaches the set temp less 4c.  After the EWP® turns off, the heat may still transfer and the electric water pump will turn on for another shorter period. The EWP® may run for about 2 minutes all up and at 6/9 amps there will be very little drain on the battery.

This set up will eliminate heat soak and the engine damage associated with it as well as significantly boost cooling when the engine is running, especially at idle.

In addition, with the old mechanical pump and a thermostat set up, the thermostat is partly closed most of the motoring time and in a cool climate at highway cruising, it is always about 90% closed. As a consequence, the flow and pressure being generated by the mechanical belt-driven pump and paid for with power and torque, are choked at the thermostat and wasted. This system has worked reasonably well for a long time but it is not smart. With your EWP® and digital Controller, power and torque is never wasted as there is no choking (no thermostat) and only as much flow and pressure as is required is produced.

We are starting to see the allowance of EWPs® in formula racing mostly to prolong the life of engines with the run on after hot shut down to eliminate heat soak. In any case, we cannot stop progress, the use of drum brakes or cross-ply tyres seem to be decreasing in racing runs. 

Our EWP®s are designed from scratch to be easy to use and easy to install.

Part of R&D is working out where best to place an EWP®.  Most are easily fitted to the lower radiator hose of your car. The hose will absorb vibration and take the weight of the EWP®  and also insulate the EWP form engine vibration.

It’s best to ensure that the pump is lined up with the radiator inlet and outlet of the radiator. ... that the belt-driven mechanical pump  can

Another reason why the pump is located low down is to ensure that minimal air intrusion occurs. The air in the coolant flow will affect the efficiency and possibly disturb the impeller’s work rate.

Should an installation be desired in the upper radiator hose, the pump’s outlet must be pointed upwards. Again, air getting into the system should be minimised.

Wiring will be dependent on the choice of installation. A wiring diagram in the kit shows how each plug connects, and how a digital controller, to be fitted in the cabin, is wired.

As there are a couple of mounting options, our next installment will be using an EWP® as an auxiliary pump to the mechanical pump.

The booster pumps flow lower rates than the EWP®s and are intended to be used in areas such as go-kart engine cooling or aiding in flow between a radiator and intercooler. All of our parts come with a comprehensive instruction sheet.

When it comes to our EWP®s, for this project we’ve selected the EWP-80. But where exactly does it go? How do we determine how to best utilise its capability?

A decision to be made is whether to use it to back up the engine’s mechanical pump or to use it as the primary source of coolant flow. Then do we use it on its own or do we use it with a digital controller? Then that way the pump can be set to run on command, or it can be, like a mechanical pump, run constantly.

Depending on which option is chosen, location and method of fitment will largely vary. However, one standard in installation will be common. The lower radiator hose is where nearly all EWP®s will be fitted and this is where, perhaps, using one of the installation kits would be a more logical fitment choice.

Our next instalment will be on the installation process.

Our EWP®s are great on their own, however in order to increase their efficiency, they can be partnered with our EWP® Kits and EWP® Combos. For the sake of keeping things easy for an example, we’ll look at a warmed over 2.0L four cylinder engine.

For engines up to and over 2.0L, the EWP®-80 and EWP®-115 will be just fine on their own.  Our EWP® kits come with the pump, and the parts needed to fit them without any extra controllers. There are also rubber sleeves, hose clamps which will assist in adapting the EWP® to larger hose sizes and the relay wiring harness.

However, the combo adds in a controller, a temperature sensor, and an adaptor to fit.  There are a number of controllers to choose from, such as the EWP® and Fan Controller (part number 8001) with this particular unit able to vary the pump’s flow depending on the temperature of the engine’s coolant.

A driver can set a temperature range of 40 degrees Celcius (104 degrees Fahrenheit) to 110 degrees Celcius (230 degrees Fahrenheit). This means that a warmed over 2.0L can do its thing and be assured of plenty of flow from either pump. Even better, thanks to the EWP® being powered by electricity and not the engine’s motion, it can be set to continue to flow after engine switch off.

Davies Craig also offer header adaptor kits which may, depending both on engine and application, suit your choice of EWP®.

Our next article will focus on the pump’s location and installation.

The classic car movement is a strong force in the automotive world. ’57 Chevys, 1970 GT-HOs, E-Type Jags, for example, populate forums and car shows. Every now and then though, a hidden gem pops up, and it’s a sure bet the owner goes to great lengths to make it both look good and help it keep its cool.

Graphic designer Anthony is one of those people.  Pride of place in his garage is occupied by a 1969 Datsun 1600 four-door sedan. It’s in classic white enamel, has a set of louvers in the rear window, rolls on stylish aftermarket wheels and rubber for extra grip, and features a pair of bonnet pins to keep the lid on the transplanted, turbocharged, Nissan FJ20 engine.

Anthony has not held back on keeping the original look but he’s cleverly masked the substantial upgrades this “pocket rocket” has under its skin! Suspension has been upgraded, the drivetrain behind the engine is stronger, and cooling is taken care of via a new alloy radiator and a Davies Craig EWP®80 Electric Water Pump unit.

Anthony’s passion for his car is shown in the way he speaks, and when he describes why he chose the FJ20 engine over the newer SR20, he brings out one key reason. The FJ’s block is well respected for its internal strength and therefore its longevity. But he knows only too well that keeping an engine as cool as possible goes a long way to that longevity.

He’s not gone hard on upgrading the engine’s internals, though. Anthony was more concerned on the cooling and specifically chose a Davies Craig EWP®80 for one key reason. Size. With the petite little Datsun’s engine bay full of…well…engine, and other bits, the Electric Water Pump's compact size made it a simple choice.

As a result of its size, and where Anthony has been able to mount it in the bay, the look of the installation, complete with belts, spark plug wires, and the pipes from the EWP® itself, help to keep the engine bay aesthetically clean and also maximizes engine bay airflow. This means that hot air isn’t kept near the block and assists the cooling system to do its job.

The car has been given some fair testing too, says Anthony. Skid pan driving, track days, and the like, have found that the Electric Water Pump, currently the smallest Electric Water Pump Davies Craig manufacture and supply, has been up to the task.

Even freeway traffic in the height of summer, when they’re more a carpark than a freeway, hasn’t found the EWP®80 wanting for efficiency in its current sate.

By that, says Anthony, he’s planning on some changes, both cosmetic (such as period wing mirrors) and technical. An upgrade to the engine’s tune will be done and to work the Electric Water Pump (EWP®) more efficiently, Anthony is installing a Davies Craig digital controller. Depending on model, these can be used in conjunction with an Electric Water Pump, and especially in a performance turbo engine’s setup, to keep cooling fluid flowing after engine shutdown, or to bring in an electric fan at a pre-set temperature.

Using Davies Craig’s EWP®80 has given the Datsun and its heartbeat confidence in all driving situations, and as Anthony explained, its compact size has enabled him to keep his vintage machine’s engine bay looking clean and tidy and is a ‘marriage made in Heaven’ for the Anthony and his beloved Datsun!

Cars have come a long way in the last century, with engines moving from a crank handle start to a battery powered ignition system. Brakes have moved from a lever and block to a high pressure hydraulic system with anti-lock smarts at each corner. Cooling has improved, with water being replaced by specifically formulated coolants and made to work with iron and alloys and moving that coolant has been the subject of research over the last two decades by Davies Craig.

What does this mean, though for the “every-day driver”? Mechanical, engine powered, mechanical water pumps tend to do the job just fine, and as they should after one hundred years or so. But Davies Craig know that their Electric Water Pump systems work just as well for Mum and Dad as they do for the drag and drift car racers or men out on the salt flats seeking speed records.

Let’s consider for a moment that the family car is in good condition but aging. Wear and tear may mean the components that help keep the engine and its internals cool may be under threat of age-related fatigue. It’s here that a brand new, electrically powered and controlled, water pump will step in to fill the breach.

They’re lightweight and efficient which means incremental fuel savings. They don’t require the engine to power them, which means fuel savings AND less strain on the driveline. Because they’re electronic they can be set to come on and perform at the driver’s discretion (when partnered with a Davies Craig LCD EWP/Fan Digital Controller), not be on operating time. And for those that just want to be sure, to be sure, they can be set to run on after the engine has been switched off, which means any residual heat can be continued to be flushed away.

And because they come in different flow rates, they can be fitted to a wide range of engines. From the humble 1.3L to a turbo 2.0L, from a straight six to a thumping V8, a Davies Craig Electric Water Pump (EWP®) will be there to suit your daily driver.

Check out our range of EWP®’s and controllers on our website. If you have a daily driver that’s a few years old and you’re using a Davies Craig setup, drop us a line and send us some pix.

Our Electric Water Pumps are designed to either supplement or replace the standard mechanical water pumps fitted and built into the car engine. But which one to select? We have four pumps to choose from and the clue as to their capacity and how much they flow per minute is in the name.

EWP®80, EWP®115, EWP®130, and EWP®150 are the names and the numbers are the flow rates, in litres per minute.

The next step is to match up the flow rates with engine size.  For a standard 2.0L engine, the EWP®80 would be fine. As a rule, the EWP®115 will suit engines from 2.0L to 3.5L in capacity. For 3.5L to 5.0L our EWP®130 will keep the engine cool and calm, and for anything larger, our EWP®150 will stand up to be counted.

However, these are for what could be considered unmodified and street driven cars. Go off-road? Have a car that’s a track day weapon? Perhaps it’s a car that’s packing a modified straight six and a block that’s no longer a spring chicken.

Here we would recommend that bigger is better. The EWP115® would be a starting point however, in a play it safe consideration, the EWP®130 and EWP®150 should be in the list.

Our next article will focus on the pump and how to match it with associated equipment such as a digital controller and/or other parts.

Drifting has proven to be a fantastic testing ground for Davies Craig products, and Swedish drift driver Andreas Forsberg knows the value of using premium cooling products.

Like many drifters, Forsberg powers his motorsport desires in the form of a Nissan coupe, and in his case the extremely popular Silvia or 200SX. Motivation comes from the opposition, a tried and proven Toyota 1JZ. The base engine came in a 2.5L or 3.0L size in a straight six configuration. Early donks were a non-turbo, with later motors featuring a pair of CT12A turbos. Power in standard trim was 206kW and peak torque was 363Nm.

Andreas says his reworked engine makes a hefty 650 rear wheel horsepower and torque is a gearbox testing 783Nm. When lighting up the tracks, power hits the ground via a Mid Valley “dog box” with four forward gears.

But it’s the engine that needs the cooling and Andreas said Davies Craig’s Electric Water Pump (EWP®) was a natural fit. His specifications for an EWP® were simple: small, easy to fit, and able to be mounted close to that monster engine to maximize fluid flow as quickly as possible.

Reliability and history also appealed to the affable Swede, with Andreas stating unequivocally that he chose Davies, Craig as they were THE number one in the business.

On the other side of the border is Norwegian drift team Sindre Davanger Racing. Sindre was inspired by the Fast and Furious Tokyo Drift film, and in May 2013 found himself a Nissan 200SX. Sindre campaigned the car with its then SR20 engine before slotting in a 2JZ twin turbo “donk”. These were well known as being the driving force in Toyota’s legendary Supra.

Sindre says that on pump petrol the revamped engine develops 500 ponies at the rear wheels, enough to have the 200SX fitted out with a fiberglass body and a proper tube-frame chassis. With a twinkle in his eye Sindre wouldn’t divulge the torque figure, but hinted at a substantial figure that the BMW sourced gearbox and diff could handle. Weight distribution and cooling has been aided by the team moving the radiator to behind the driver’s seat, with Sindre saying the Davies, Craig EWP® were the only choice to feed cooling fluid to the rear.

Again reliability was seen as a number one priority. Sindre had asked around, spoken to other drivers, and the feedback was overwhelmingly DC. An attractive local price sweetened the deal, says a smiling Sindre, and in competition conditions he reports that there have been zero issues, taking as much pounding as the powerful 2JZ engine with 6262 turbo and 1400cc injector system can deliver.

Davies Craig is recognized worldwide for their range of Electric Water Pumps, Digital Controllers, Thermatic® Fans, and more. Here are two great examples of how a Davies Craig EWP® cope with the rigours of extreme motorsport, and if they work here, they’re good enough to handle your car.

For the most part, the air we breathe was the source of cooling. This was quite appropriate when engines were fitted to aircraft but not so for the automobile which frequently had no forward movement.

Yellow Pro Shop recently installed a Davies Craig EWP on their GT86.

Heat exchange devices, radiators, came into being and were connected to engines via various hoses. In order to move fluid through the radiator and to exchange heat with the atmosphere, the earlier mechanical engines firstly relied on thermosiphoning. This is a method of passive heat exchange, based on natural convection, which circulates fluid without the necessity of a mechanical pump. With the increase of engine sizes and power outputs the engine needed a device to pump the fluid and mechanical belt-driven water pumps were added.

But it was becoming clear there was a need for alternative power sources and refinement of coolant flow through the engine  was required. Immediately this opened up a whole new area of research and development, along with cooling options for different types of engines.

An electric water pump can be made to be a simpler device, in a better way, than a mechanically or engine driven unit.  Also, too, the Electric Water Pump  can be made to be smarter than a mechanical driven device.

Davies Craig Pty Ltd is a 50-year Australian owned and operated based company that offers a multitude of ways to electrically cool automotive engines.  Through constant research and development, Davies Craig offers a wide range of Electric Water Pumps (EWP®), Thermatic® Fans, and LCD EWP®/Fan Digital Controllers.

The Electric Water Pumps (EWP®) themselves are designed and engineered to flow a constant coolant flow through the engine and radiator, totally independent of engine revolutions. There are four Electric Water Pumps (EWP®) flow rates, of 80, 115, 130, and 150 litres per minute of constant coolant flow. movement.

Rios_racing with a Davies Craig EWP on their engine before getting boxed up for a trip to France.

They’re a compact size which means they can be simply located on most engine’s bottom radiator hose inside a car’s engine bay.

But to really take these (EWP®s) to the suitable level, the appropriate flow rate to suit your particular engine capacity needs to be considered. For example, the EWP®80 Electric Water Pump is suitable for engines of up to 2.0L in capacity.

Do you have something along the lines of a bigger four or a smaller six? The EWP®115, and EWP®130 Electric Water Pumps will be fine. But to really be sure, or to cope with larger  engine capacities and in high stress motorsports situation, the Davies Craig EWP®150 will hold its own.

In order to make this all work there is the patented Davies Craig LCD EWP®/Fan Digital Controller which allows you to set/target your engine’s operating temperature. It can be programmed to manage the speed of coolant flow, commensurate with engine temperature, through the cooling system and will also control coolant flow after the engine’ ignition is switched off.

With advice from our qualified Davies Craig consultants, there is a EWP® Combo Kit to suit virtually every application and vehicle. All EWP® Combo Kits are designed for simple do-it-yourself (DYI) installation anyone with the basic mechanical knowledge. (check out our YouTube channel for help with the installation process).

As always, Davies Craig remains at the forefront of producing the world’s best Electric Water Pumps (EWP®) and associated engine cooling equipment. We’d love to hear from you about what you’ve fitted from the extensive Davies Craig list.

Unlike the others, the answer to what is an electric water pump is surprisingly simple to divine.

An Electric Water Pump, or EWP®, is an electrically driven unit that pumps water or more commonly called engine coolant. There, sounds simple. But wait, there’s more. One immediate benefit of an EWP® is in the name, the word ‘Electric’.

Because it utilizes that amazing and invisible power, an EWP® isn’t reliant on the spinning of a crankshaft, the rise and fall of conrods, and the pulsing of injectors. They work as long as there is juice in the battery. This means that if a car or truck or bus has been running for a while and the ignition gets switched off, a control device can keep the EWP® running-on after hot engine shut-down. This is especially crucial in automotive high load areas or in motorsport.

Consider a drift car, running a high revving petrol engine and fitted with a turbo. A talented driver can pound a drift car around a circuit and the engine will be constantly working hard. The driver gets to the end of their run and switches off. A mechanical water pump them immediately stops working. This means cooling fluid is no longer pushed through the engine internals and through the radiator. This can lead to severe damage to the engine and potentially the radiator as well.

Another benefit of an EWP® is the constant pressure and flow rate. An easy comparison is a child’s toy fan. Blow gently upon the vanes and it’ll spin slowly. Give it a good huff and it’ll spin hard before winding down. That’s a mechanical water pump, rising and falling with engine revolutions.

An EWP® suffers not from this, and EWPs from Davies Craig, with flow rates of up to 150 litres per minute, will CONSTANTLY deliver flow, as they’re not dependent on a crankshaft and belt to spin.

And because they’re electrically powered they’re not sapping energy from the engine, allowing this extra power to go to the drive wheels. This means less strain, better fuel economy, and longer lasting mechanical parts. The EWP®s are a good deal smaller, which means less weight, better efficiency, and can be mounted in certain positions to help tidy up an engine bay.

Is it worth mounting EWP^®s? In order to make sense of this, what is the difference between ‘series’ and ‘parallel’ when it comes to installing a pair of EWP^®. A simple way of looking at this is Davies Craig Electric Water Pumps can be installed in either in ‘series’ or in ‘parallel’. Using the car battery as an example, as illustrated below…

Batteries can be connected in either series or parallel like EWP’s. So, to acquire 12 volts, two x 6-volt batteries must be connected in ‘series’.  The same two x 6-volt batteries connected in ‘parallel’ produce 6 volts, but the current doubles. Relating these scenarios to EWP installations/connections to an engine – if we resemble head capacity to voltage, and flow rate to current, both types of connections have certain advantages;

Two EWP^®s connected in ‘series’ (in line) doubles the head capacity of a single EWP^®, while the flow rate remains the same as with a single EWP^®.  Two EWP^®s connected in ‘parallel’ (side-by-side) doubles the flow rate capability when compared to a single EWP^® while the head capacity remains the same as a single EWP^®

For example, Davies Craig customers with high cubic capacity, high horsepower engines are having marked success with two x EWP®s mounted in line. One is controlled by a Davies, Craig Digital Controller (Part no 8001) set to the engine’s targeted/set temperature and wired to the ignition. The other EWP^® is operated by one of the Davies Craig Thermatic Switches, Part #0401, #0444 or #0500, wired directly to the battery and set to switch on at a few degrees above the Digital Controller set/targeted temperature, which should be set at a similar temperature as the manufacturer’s thermostat temperature, which can be removed or 2 x 5mm holes drilled in the plate.

Let’s say that our totally nuts hi-po engine really pumps some serious horsepower. It probably means that cooling is good but could be better. Investigation shows that our current water pump is struggling and could do with a boost.

To be on the safe side, some high flowing units are investigated and let’s say the Davies Craig EWP150 looks like it might do the job. But we can fit two EWP115s instead to achieve around 230 litres of total flow and a pump that kicks in at a pre-set level to back up the first one.

This is where operating two EWP^®s becomes like our battery analogy. One pump will flow 115 l/min, but you want two to flow approx 230 l/min, which way do you go?

In series two EWP115s will look like they’re flowing approx. 230 l/min, but it’s actually only the capacity that doubles, not the physical flow rate. In ‘parallel’ these two EWP^® combine to flow the full 230 l/min yet appear to be, effectively, one EWP^®.

Here we have a pair of EWP^® that on their own will do a great job but only with engines producing less power than a performance engine. Two smaller EWP^®s though can add that extra flow rate needed and can be set for one pump to continue flowing fluid to assist in the cool-down process after engine shut-down.

Are you running more than one Davies Craig EWP^®? Show us yours and provide some background on our social media outlets.

This is important because if we make a claim that a product will do something, such as our EWP® 150 pumping 150 litres of fluid per minute, we should be able to back that up.

Recently we put our EWP® 150 to the test, and in order to really put it under pressure, we added in a factor of competition. We took one of our competitor’s water pumps and put the two up against each other to see if their claim could be backed up.

The competitor’s pump is said to pump 55 US. gallons per minute. In our lingo that’s 45 gallons per minute, or 208L per minute. The EWP® 150’s rate was tested at 40 US. gallons per minute, which equates to a breath over 150L per minute.

As it turned out, the Davies Craig EWP^® 150 not only drained the test tank quicker than the competitor, it did so by a good margin. Adding to this was the compact size of the EWP® 150 in comparison to the competitor. Attached to separate pipes the Davies Craig EWP® 150 is clearly more compact and also quieter in its operation.

What does this mean for the consumer? It means that our R&D, and our engineering and design teams, combine to say that our claim of 150L per minute is completely provable and that a more compact and lightweight unit can certainly do the job in a manner demonstrably more able than larger units.

It’s impossible to understate how critical cooling is in motorsport and Joachim Waagaard knows this only too well. Joachim, you see, is a drifter.

No, not one of the battered and travel weary souls that hop from train to train in search of a better life, he pounds a BMW M4 around race tracks at 45 degrees to the straightaway, leaving plumes of smoke from his shrieking tyres behind him.

Waagaard hails from Norway, a country not known for drifting. What drivers from that snow-locked country are known for is rallying, and the soon to be 30 year old (November 14 is his birthday, if you want to send a card) started in motorsport in his tenth year of life. Like so many, he followed the path of go-karts before moving into the heavier metal of car racing, and this started at the age of just 17.

Waagaard started in the technically demanding motorsport of drifting just a few years ago as part of the Powerdrift Norwegian Drift series. He made his mark upon the scene with a Chev LS3 powered Mazda RX-7.

This brought him to the attention of the organizers of the Goodwood Festival of Speed event in 2015, marking the first time a drifter driver from Norway had been invited to perform at this hallowed event.

Recently, Waagaard has made himself present on screen with a stint that placed him in a Sach’s commercial on the ice with his BMW M4, as well as having the opportunity to be a stunt driver in a new Bollywood film. To top off an already remarkable year, Waagaard and his team were filled with excitement after getting their hands on a race truck where his trusted M4, along with spare parts and other drift related necessities are now situated.  

His current car is substantially modified from standard, running a 6.6L Chev LS2 V8 pumping out 620hp and 815Nm of torque. With the strain that a drift event puts on engines such as this, Joachim has selected Davies Craig to be his cooling supplier via our Davies Craig EWP^® 150 system. With up to 150 litres of coolant per minute being fed through the radiator and engine, Joachim knows that this setup is just what he needs to keep cool as his 2015 BMW shows its might as it’s punched around the track.

Davies Craig is a huge supporter of motorsport and is able to lend vast reserves of experience to people, teams, and companies around the globe. We’ve been to the salt flats of Bonneville, worked with British universities, and run with Aussies here in Australia.

Aftermarket companies have come and gone, and with Davies Craig due to celebrate the big five-Oin a couple of years, it means we’ve been doing something right. There’s ongoing R&D to ensure our existing products remain at the leading edge of their field, and improvements built in to upcoming designs so they’re on the mark when they’re ready for sale.

One place we’ve been to, the Bonneville saltflats, was along with Greenspeed Research from Idaho.  They’re a little different in that they took a tilt at speed records with a vehicle powered by biodiesel.

Running a two door ute, and fitted with a pair of Davies Craig EWP^®150’s, the green machine saw top speeds of over 240 kilometres per hour. The renewable energy powered racer was able to complete a number of trouble-free runs at around the 150-170 mph mark. The team gained valuable insight into what kind of immense pressure running cars in this extreme environment have to deal with, and the requirements to stay cool. There’s a good chance they’ll be back at Bonneville this year, and we’ll be there to help.

John Crowhurst knows all too well how Davies Craig’s EWP^®150s work. John runs a vehicle that is, to say the least, both unusual and historic. Our EWP^®150s are bolted into a chassis of car that’s largely hand built, looking like a blower Bentley from the 1930s. Power comes from a piece of aeronautical history.

Based on the same engine that spun the propellers of Spitfires, and sporting the same name as Britain’s first frontline jet fighter, Meteor, John called in the help that Davies Craig provides with their products, and the EWPs help cool his engine, all twenty seven litres capacity’s worth.

We don’t mind a bit of tarmac action either. Along with the normal assistance provided to car buyers, caravanners, and the like, we’ve worked with straight line speed demon Josh Backes to help his drag Chevelle keep its cool.

Capable of flattening a quarter mile in just 11 seconds, thanks to a 400ci V8, Josh had fitted a Davies Craig EWP^®150 and a Davies Craig 16 inch puller fan which went a long way to lowering his once plus 12 second times. With drag race engines also needing to stay as cool as possible, even in a short run thanks to heat soak afterwards, our tried and proven in combat equipment that’s helped people like Josh, John, and the good people at Greenspeed, will be there to help your car stay cool in just about every environment.

Davies Craig use a step by step procedure, and here is how it works for the Coyote Adapter kit. No step, however seemingly silly, has been left out.

Step One:            Remove the radiator cap then disconnect the bottom radiator hose to drain the coolant from both the radiator and engine into a clean tray. If the coolant is clean and free of foreign matter it may be reused. Retain the bottom radiator hose, you may require a section of this hose to complete your EWP^® Coyote conversion.

Step Two:            Loosen appropriate water pump hardware and remove drive belt. Disconnect heater return hose and remove the mechancial water pump from the Engine Block.

Step Three:        Retain the bolts from the detached mechanical water pump as these will be required to attach your Coyote EWP^® Adaptor Plate. Clean the surface of the engine block to ensure it’s free of the old gasket and any grime and coolant.

Step Four:     Pre-Assembly – take the Coyote EWP^® Adaptor Plate and place the small O-Ring provided over the surface of the inlet. Secure the 38mm (1½”) Straight Adaptor onto the Coyote Adaptor Plate with the 6 x M5 Screws provided. When mounting the Straight Adaptor to the plate ensure the O-Ring is properly positioned. Take the large O-Ring and place in the groove located in the rear of the Adaptor Plate. Find a clean pair of gloves and use some quality cleaning products to ensure the front of the engine block is as clean as possible, especially around the area where the gasket will sit. This is essential to ensure a good, tight, fit for the new parts, and minimize dirt entering the engine’s internals.

Step Five:    Slide the Coyote EWP^® Adaptor Plate Assembly into the open profile on the engine block where the mechanical water pump was positioned, ensuring the large O-Ring sits in its groove and mounting holes align with those on the engine block. Secure plate in place with existing hardware.

Step Six:  Secure the 90° Hose to the 38mm (1½”) Straight Adaptor with large hose clamp provided. Then slide the In-Line Adaptor into the bottom end of the same hose and secure with large hose clamp supplied. Then secure the bottom radiator hose (if serviceable) to the In-Line Adaptor with a large hose clamp supplied. Secure but do not fully tighten. If required, place one 3mm rubber sleeve supplied on each end of the In-Line Adaptor. Do not tighten.

Step Seven:   Pre-assemble the Heater Return Adaptor to the EWP^® inlet using Teflon tape to prevent any possibility of leaking. Align the EWP^® with the bottom radiator outlet. Ensure your EWP^® is located as low as possible relative to the bottom of the Radiator outlet to assist with bleeding trapped air. Use a small portion of the bottom radiator hose to secure the EWP^® to the radiator outet, (the remainder of your current bottom radiator hose may be suitable for this purpose). Connect the radiator hose with a large hose clamp (supplied) to the EWP^® inlet. Then fit the other end to the bottom radiator outlet with a large hose clamp (supplied).

Step Eight:          Remove existing Heater Return “T” piece from Mechanical Water Pump. Connect this piece to the Heater Return Adaptor using heater hose and clamp, (supplied).

Step Nine:    Connect the second 90° Hose (supplied) to the engine coolant outlet. Join the 90° Hose to the top radiator hose using the second In-Line Adaptor Nylon and hose clamps (supplied). Fit the new belt (supplied). Take the other 90 degree radiator hose and connect and clamp to the 90 degree hose on the adapter plate. 

Step Ten:   Once you are satisfied with the initial assembly and alignment of your EWP^® and EWP^® Header-Adaptor Kit conversion, proceed with final assembly ensuring all hose clamps, screws and bolts are sufficiently tightened to prevent   leaks.    Be careful not to over-tighten. Place the new Davies Craig Electric Water Pump next to the open end of the radiator hose, ensure a clamp is on that open end, and push the EWP's connecting plug into the hose. Clamp and allow for adjustment if necessary. It’s here that the Davies Craig Electric Water Pump then has the ½ inch heater hose plugged into the front top hose connection. This is the heater return hose adapter.  Again clamp and allow for adjustment.

Step Eleven:      Follow the LCD EWP^®/Fan Digital Controller installation instructions to complete this part of the EWP^® conversion. Using the T shaped heater return plug from the existing hardware, refit that to the appropriate hoses.

Step Twelve:   Refill the radiator but not replace the radiator cap at this point. Then start the engine. Your EWP^® and EWP^®/Fan Digital Controller combination will commence its pre-programmed ‘test’ mode and operate the EWP^® at full speed for 5-10 seconds. Turn on the vehicle’s heater (if applicable) to the maximum setting. Run the engine for approx. 10 minutes while carefully monitoring engine temperature. Top up coolant level as required. Switch off engine. If you are satisfied your cooling system is completely free of air, replace the radiator cap. Restart engine, run up to operating temperature checking all fittings are secure and observe for any leaks. Switch off engine and re-torque any fittings and hose clamps if required. Check coolant flow in the heater lines. N.B. If you find the heater is not functioning correctly, you may be required to fit an EBP15 Electric Booster Pump, (part #9001) to the heater line.

Mount and clamp the bottom radiator hose to the front of the Davies Craig EWP^® which is the section that also holds the ½ inch heater hose. Finish the installation by connecting the Davies Craig LCD EWP®/Fan Digital Controller to the Electric Water Pump and mount the EWP^® following the instruction sheet. Check all mounting bolts and clamps, and tighten as required.

Final Step:           ‘Road test’ the vehicle, running the engine up to operating temperature. Again, turn the heater full-on to assist purging of all air from the cooling system. Allow engine to cool down, check coolant level again, topping up if required. Please repeat the above process until you are satisfied your engine’s cooling system is totally free of air, all hose clamps and hex cap screws are tightened satisfactorily to avoid any leaks. You should check your cooling system thoroughly after 20 hours of operation.

If you are having any difficulty with your Installation, give Davies Craig a call and our qualified service staff will assist.

Beavis Motorsport, EWP115 installed into MX-5

Brendon is a racer and is building a Mazda MX-5 to compete in a “Time Attack” event. He points out that the Davies Craig EWP115, or Electric Water Pump that he purchased for his build, is available in high-strength Nylon or Aluminium. In this video Brendan opts for the Davies Craig EWP115.

He noticeably points out that he doesn’t see any difference between the pair, apart from the Nylon version being 300 grams  lighter, and in motorsport, any form of weight saving is crucial.

Brendon highlights the fact that some parts of the existing installation do need to be kept as they’re an integral part of ensuring the new Electric Water Pump is correctly mounted and remains firmly attached to engine components.

As he disassembles the front of the engine, Brendon points out that some parts of the existing installation are no longer required, meaning further weight savings, plus a new serpentine belt may be required.

Davies Craig, What’s In the Box?

It’s Rick from Rally Sport Direct. Rick doesn’t point out the specific model number of the Davies Craig EWP but does highlight that it’s for a Subaru WRX that was built between 2004 and 2007.

Rick has the parts laid out clearly before him, and starts by showing the EWP115 Combo Kit itself after mentioning that the kit on display has been installed and working well in a vehicle. He does make a point of showing a blanking plate is required, a plate that deletes the old pump and saves both weight and horsepower loss.

Highlighting the patented Davies Craig Digital LCD EWP/Fan Digital Controller is a big part of Rick’s presentation. He uses the words: “This is the brainbox. This is where the magic happens. You’re going to be able to control exactly when you want the pump to kick on, at what temperature, and hard you want it to kick on”, describing exactly how flexible in usage a Davies Craig EWP’s “brainbox” is. He also points out it can be set to alert a driver of excessive heat in the coolant flow.

Finally Rick also highlights the kit includes EVERYTHING needed to install a Davies Craig EWP115 Combo Kit. The Kit includes wiring harnesses, clamps, sensors, and adaptors. He wraps by pointing out an approximate timeframe to install and just how effective the EWP115 Combo Kit is for his engine.

Our final video kicks off with “Broomy” looking at a Davies Craig EWP150 Combo Kit (part #8970). He calls it a turbocharger for your water system, and that’s an apt description, both for the looks, and for the way it works.

There’s an identification of one the main issues that a Davies Craig EWP is designed to overcome, particularly in a motorsports environment. A mechanical water pump may produce what is called “cavitation” at high engine revolutions. This is a process where a spinning object in a liquid may spin at a speed that produces bubbles and this reduces efficiency. He also points out that when an engine is switched off, a mechanical water pump is also off and therefore producing no cooling flow.

Broomy describes a benefit of a Davies Craig patented LCD EWP/Fan Digital Controller when used with a modern car’s ECU in that it can be wired in separately to the ECU meaning its own controls can bypass the car’s ECU for greater flexibility. Broomy also describes the pulse width modulation (pwm) feature of the EWP and Digital Controller, meaning it builds up the cooling fluid flow, rather than delivering an overload which could damage an engine’s cooling system and the engine’s internals by cooling too quickly.

In respect to a switched off engine, Broomy thinks the Davies Craig EWP’s ability to be programmed via the Digital Controller to continue spinning and providing cooling, in conjunction with a Thermatic fan, to ensure that the engine is receiving a steady flow of coolant. In a racing environment, this minimizes engine and cooling system issues, and maximizes the downtime efficiency.

Another benefit that Broomy points out is the flexibility of the EWP and Digital Controller as it’s suitable for cars with carbies or “exotic” mechanical water pumps, again highlighting the sheer flexibility of the EWP Combo package. And by removing a thermostat, and implementing an electronic system, the possibility of a mechanical system’s failure is pretty much negated.

Broomy rounds out his presentation by stating his company’s loyalty to Australian Owned and operated Davies Craig Pty Ltd by saying they’ve used the products before, and points out the Australian design, engineering, and manufacturing of the products.

Virtually all the products from Davies Craig are sealed units, which means they’re protected against dirt and moisture. Electronics are solid state, meaning no moving parts to wear out. However, some exposed areas will need watching, just like standard parts.

Electrical connectors are perhaps the ones to watch the most. If it’s unavoidable to have exposed metal parts then a dab of grease or a lubricant will offer protection. Some electronic retail stores may have silicon or rubber “boots” which will cover the exposed part.

One great thing about the EWPs that Davies Craig sell is that they’re far less prone to wear unlike a mechanical water pump. But it certainly doesn’t hurt to switch the system on and have a listen to the EWP itself. What may be heard is a whirr, a slight rattle, a mechanical noise that shouldn’t be there. These could be a sign that a visit to a Davies Craig authorized stockists may be needed, just to check things out. Alternatively, reaching out to us via our contact us page or social channels.

If a visual inspection of the car’s engine cooling system shows seepage, or leakage, of fluid, particularly of a green hue, this could indicate a gasket failure or perhaps a part is slowly working its way loose. If a gentle adjustment with a socket or spanner shows bolts are tight, then a visit to your workshop or your local friendly mechanic with details of your Davies Craig equipment could pay off in nipping a potential issue in the bud.

Any extra load on a car’s cooling system will test it to a point. Consider that all vehicles undergo stringent testing in a variety of climes to ensure the door seals, the suspension, the air conditioning all work across various climatic situations but rarely, if ever, is towing mentioned as a factor aside from the “braked towing capacity”.

Because an engine’s workload is increased when towing, an improved cooling system will go a long way to help your car keep its cool under stress. Davies Craig provides a number of options that are specifically designed to increase the survival factor of a car’s cooling system and for almost any towing situation.

Davies Craig’s EWP® Electric Water Pumps take some of the mechanical load off an engine when it comes to circulating coolant through an engine. However, in order to be even more assured, an electric Thermatic Fan will offer even more engine cooling by forcing or drawing air through your car’s radiator.

Firstly, a look at the kind of vehicle being used, and how often, in order to determine the kind of equipment needed. Is the car a small four cylinder and used for a light trailer load? Perhaps a torquey six cylinder or a diesel V8, and used for a trailer with dirt bikes or perhaps a good sized caravan?

The EWP® range from Davies Craig are designed to provide a more consistent coolant flow commensurate with engine temperature. The EWP® models cover engines from small four cylinders to large capacity V8s. In order to assist with engine cooling, one needs to examine the radiator and it’s generally accepted that for towing, an “downstream” mounted fan, one located on the engine side of the radiator, will provide the better air flow for towing and cooling.

Paired with a Davies Craig LCD EWP/Fan Digital Controller, the Thermatic® fans can be programmed to engage as required and pull air through the radiator to perform the heat exchange needed to generate cooler fluid. If a car is towing a light load then the Controller can be set to engage at a set/targeted temperature.

The benefit of installing and operating the electrically powered fans and pumps is the extra power released that can be used by the engine. Mechanical strain on engine components is lessened, meaning increased longevity, and economy may also increase, subject to driving conditions. Check out our product list on the website and match up the right parts for your car.

With this, it is with great pleasure that we announce the relaunch of our EBP®25 Electric Booster Pump! The EBP15, EBP23 and EBP40 have all drawn high recognition around the world– and the newly updated EBP 25 will now complement this versatile range.

Through rigorous testing and better understanding what Davies Craig customers want from our range of products, we have developed the compact, lightweight EBP®25 which now offers –

• Brushless motor
• higher flow capacity
• higher head pressure than the EBP®25 model it supersedes
• lower current draw

Because the update means the EBP®25 is lighter (650 grams/1.43 lb), more compact, and has higher head pressure than the current EBP®25 it replaces, the potential to utilize this EBP among a wider variety of applications becomes one major benefit. The Electric Booster Pump offers the perfect solution for all water-to-air intercooler and turbo/supercharger kit applications among a wider range of applications including; camping, caravan, SUV, marine, solar and much more.

Additionally, the mechanical design of the updated EBP®25 itself has a brushless, centrifugal pump which further eliminates brush wear (where if not eliminated, can necessitate frequent maintenance and downtime) common with conventional brushed electric motors. This ensures increased lifespan of the Electric Booster Pump.

To add to the already significant upgrade, we’ve also included the mounting bracket for this Electric Booster Pump, ensuring the installation process is as easy as possible. And for further safety, the updated EBP®25 also comes equipped with reverse polarity protection and overvoltage protection, meaning your new EBP becomes less prone to electrical damage.

Looking at the previous EBP®25 and the updated EBP®25 gives us a bit more of an indication on the improvements that have been made.

The newly updated EBP®25 can also be used to enhance OEM engine cooling systems, improving coolant circulation especially in LPG conversions and greatly assisting the management of engine temperatures. 

With the launch of the updated EBP®25 unveiled, 2019 is continuing to prove a tremendous year for Davies Craig, with the new #0500 having also been recently released. Which features would you like to see added on our products? Let us know through our social channels!

But what about the times you want to get dirty? Taking a 4x4 off-road is something that most drivers never do, but those that enjoy getting dirty will ensure that their mechanical system is in tip top shape, and they’ll ensure their electrical system is sparking just fine. And their cooling?

Davies Craig has helped many off-road drivers and racers with their vast ranges of fans and controllers. Air and fluid flow are critical when working an engine hard, and when off-roading, thermal stress and constant fluid movement need as much cooling as can be delivered.

An ideal off-road cooling system needs high, constant, air and  COOLANT flow, a thermo switch and fan controller to bring in those flows as required, and high flow electric water pumps. The EWP-130 or EWP-150 from Davies Craig would be ideal here. With rated flows of 130 litres per minute and 150 litres per minute, these electric water pumps will be perfect for circulating hot and stressed fluids.

And both are lightweight too. Made from powder-coated aluminium, the EWP130 is tipping the scales at just 1.226 kilos, and the EWP150 a little less at 1.170 kilos. This means less mass than a cast iron item, better heat dissipation as they work, and less mass for a car to move around.

Partner these two big flowing items with a fan to suit the radiator and a digital controller that varies the pump’s and fan’s flow as & when required, and the off-road experience becomes more enjoyable thanks to the peace of mind Davies Craig offers.

www.daviescraig.com is the one stop online shop for your off-road compatible cooling equipment needs. We’d love to hear about your off-road exploits and how your Davies Craig fans and EWPs helped you keep your cool whilst getting dirty. Check in via our blog comments or our social media pages.

It’s far from standard, but achieving 238kph (148mph) in a VW Beetle is no mean feat and owner Mike Drewer from Adelaide in Australia believes it can go even faster.

Drewer built the ‘chopped’ VW Beetle with a Subaru WRX Turbo power plant specifically to run at Speed Week on the salt lakes at Lake Gairdner in South Australia and achieved close to 150mph earlier this year.

‘The car can definitely go faster, but we need to improve the handling and stability. Driving on a salt lake at speed is not as easy as one would think. There is the loose salt and side winds, and a VW Beetle wasn’t the most stable of cars at around 70mph!

Drewer brought his son Tom back from the USA to drive the car and the former American IMSA Sports Car champion agreed that it was a big challenge. ‘I really had to hang on to the car and use plenty of track. It was slightly frustrating not to actually achieve 150mph, but next year I am sure we will go a whole heap faster’.

As for the involvement of Davies, Craig in the project it has been quite extensive.

Placing a water cooled Subaru engine in a car set up for an air cooled power plant and replacing a 36hp engine with one that is developing around 350hp involves special challenges.

The aluminium radiator is positioned horizontally where the original VW fuel tank was placed and cool air is drawn through it by two Davies Craig electric fans.

A Davies Craig electric water pump replaces the original Subaru unit and provides a number of advantages., namely a slight increase in power and  more importantly providing the ability to control the engine temperature very accurately during  warm up, pre run, and full power phases.

‘I am particularly impressed with the engine temperature control provided by the Davies, Craig electric water pump. Air temperatures at Lake Gairdner can be extreme (up to 40 degrees), and we have to wait in line for our high speed attempts. We need to have sufficient temperature in the engine at the right time and the EWP allows us to achieve this’    

A second Davies Craig electric water pump is used to circulate fluid through multi copper coils in an ice-slurry filled box to the turbo charge cooler to provide the lowest possible engine intake temperature.

‘This is also a great solution for our particular purpose as we didn’t want a normal intercooler hanging out in the airstream. The ice box solution with the electric water pump is great and we can even cool the charge cooler down before we actually start the engine’. 

‘What we have achieved with this car has made for an interesting challenge, and has been a great R&D project tested in the real world in very harsh conditions. The Davies Craig products has come through with flying colours’ 

Dedicated to 1947-87 custom and restoration truck builders, their recent issue (January) showcased the transformation of a Small block Chevy kit where swapping multiple drivebelts for a single drivebelt with a Vintage Air Front Runner was completed.

During the transformation process, the team at Classic Trucks also included the addition of dual electric charge cooling fans. And this is where the Davies Craig products stepped in.

A pair of dual electric engine cooling fans made by Davies Craig and distributed by 3PConnect were installed, where they came configured to be used as pushers in the front of the radiator.

The Davies Craig dual Fans not only offered the new Chevy engine an increase in performance and fuel economy, but also offered compatibility with all electric fan controls. Classic Trucks took full advantage of this feature with the use of the FiTech fuel-injection computer to control the pair of fans.

Overall, the swapping of the drivebelts was transformed successfully, giving this Chevy engine its optimal performance, without needing multiple drivebelts.

This is just one of the many projects that Davies Craig continues to support across the globe. Do you have Davies Craig products installed in your vehicle? Head to our social channels and let us know your experiences with our range.

In simple terms, heat is generated inside an engine from movement and the ignition of fuel. That heat is transferred into the engine itself and must be removed as quickly as possible. Radiators or heat exchangers do a good job of this but rely on fluid circulation and air movement in order to dissipate that heat.

Fans attached to engines soon assisted in that but a clear need to improve upon that was recognized. It’s 1971 and a pair of Aussie engineers, Daryl Davies and Bill Craig, put their heads together and gave the world the electrically powered thermatic fan.

The benefits of a non-engine driven fan became immediately apparent. There is a lack of drag on the engine itself, which means more available horsepower, better fuel economy, less wear and tear, and better air-conditioning performance thanks to a constant airflow when required.

Another benefit is the added airflow from the versatile design. Rather than being only to spin in one direction by being bolted to the front of the engine, an electric fan can be reversed so it can push or pull air, depending on placement.

Davies Craig, as a result of their engineering background and history, continually refine and improve their products. Wind tunnel testing is familiar to us for aircraft and car design, as two examples, however it’s also been applied to the fans and the shrouds of the products. This reduces turbulence at the far end of the fan blades and the shrouds direct air more efficiently. Even the blades themselves were refined and will continue to be as technology improves. It also ensures that Davies Craig can back up their claims with real word testing and results.

Logic applies to the fans as well. One can go and buy a fan attached to a pen and powered by a small battery, and that will be almost adequate to cool a human face. But if a room is to be cooled, a bigger fan and a higher level of airflow is needed. As a result, Davies Craig have engineered a range of fan sizes. This allows a wide variety of applications, from small cars to family sedans and SUVs, to trucks and motor sport applications, in sizes starting at 8 inches and going all the way to a massive 16 inches.

But in order to work as intended, there has to be a range of electronic items to back the hardware up. There are different mounting kits, different kinds of temperature readers, and systems to suit the different electrical outputs of varying vehicles.

Davies Craig have an online store for added convenience, and back up their products with excellent customer services plus an industry leading two year warranty.

Automotive cooling systems have been streamlined in the last three decades. This includes coolant types, radiator manufacturing and materials and associated engine coolant parts such as hoses and of course, there is computerised engine management systems.

Davies, Craig Pty Ltd is Australia’s premium aftermarket supplier of automotive engine cooling products and with plenty of older vehicles still on Aussie roads, Davies Craig stands well placed to provide the appropriate equipment for all engine cooling requirements.

Engine cooling systems once relied heavily on a Mechanical Water Pump (MWP). These are belt-driven and are generally integrated into the engine block. The earlier radiator construction wasn’t as sophisticated and plain tap water was generally the chosen cooling fluid.  Moving into the 21^st century and the cooling efficiencies have moved forward. Water is not the single cooling liquid which has now been mixed with anti-boil, anti-freeze glycol-based fluid to prevent the build-up of calcium scale which blocks cooling system passages and eventually leads to core blockage and engines overheating.

Davies, Craig is a 50-year old Australian manufacturer which has been designing  Thermatic electric fans and Electric Water Pumps (EWP^®) plus supplies Installation Instructions for simple, do-it-yourself fitment. Thermatic Switches and the patented LCD/Fan Digital Controller read coolant temperatures commensurate with engine temperatures. For example, a pre-set/ targeted temperature will allow the electric engine fan to be automatically switched on and allows both the EWP^® and the Electric Fan to run-on after hot engine shut-down. Bing electrically powered, there’s no demands on the engine’s mechanical power delivery, which aids fuel economy.

An added bonus to a EWP^® installation is the weight saving. Up to three kilos may appear incidental but over time will reduce wear and tear on belts and pulleys in the engine bay.

Davies, Craig manufacturers a range of EWPs offering specific flow rates up to 150 litres/min. There are pumps and accessories to suit low volume engines or older vehicles used for historic club drive days. There are accessories to suit the varying voltage systems, from 6, 12 volt to 24 volt, and Electric Booster Pumps EBP^®s for those that prefer the two wheeled mode of transport.

Davies, Craig is also able to provide EWP^® systems for modern vehicles as well as Transmission Oil Coolers; these cooling products are suitable for those who wish to ensure their cars, SUV, 4WDs etc. used for heavy payload situations and constant towing will also never suffer the humiliation of the roadside bonnet up call for help.

At a glance, the new Digital Gauge Thermatic Fan/EWP Switch projects bright, attractive and compact high visibility with a 52mm round LED digital display for easy reading and quick adjustment. But when put under the spotlight, this product offers much more.

Set Temperature: An easy to reach and convenient push-button allows the user to accurately set/target temperature for automatic activation of the Thermatic Fan #1 and Fan #2 at independent temperatures when extra cooling is vital. These numbers are displayed accordingly on the digital gauge.

Easy Installation: The Digital Gauge Thermatic Fan/EWP Switch provides simple and straight-forward installation instructions to avoid issues throughout the setting up process.

A/C Override: Not only does the new gauge offer fan override by A/C control, users are also given independent control of A/C override (Fan #1 or Fan #2, or both).

Temp Warning Indicator: One new critical feature added to the digital gauge is the temperature warning indicator. When temperatures rise to critical levels, an audible alarm sounds and the temperature is also read out.

Temperature Detection Range: The detection range of the new Digital Gauge Thermatic Fan/EWP Switch has an increased temperature detection range 0°c (32°f) to 130°c (266°f), with the ability to incrementally adjust when necessary.

Looking at thermatic switches #0401, #0444, and #0500 side-by-side illustrates the differences between  the three highly successful products, which can be viewed below…

The team made the trek up the freeway to Winton in early December to take on some of the world’s best FSAE competitors in several judged events including autocross and an endurance component. The competition was close; however, the team was able to come away on the overall podium in both classes.

Monash Motorsport run a Davies Craig 9” Thermatic Fan and EWP80 aboard their internal combustion engine racer, which is uniquely powered by a KTM 690 Duke-R engine. Weighing in at under 300kgs, the car is incredibly nimble and thanks to features such as an active DRS (drag reduction system) has very low drag, making it perfect for this style of competition.

Formula SAE was developed to further educate students in all assets around Automotive Engineering, with universities from around the globe designing, building and competing in their own custom-built racers. Resembling a hybrid go-kart/Formula 1 car the futuristic racers rely heavily on high-tech aerodynamic principles such as wings, splitters and undertrays.

The team now heads on break over the Summer after an action packed 2018. Stay tuned for more updates on the Monash Motorsport crew throughout 2019!

If space permits, should I mount single or dual Thermatic Fans?

Like anything, it’s personal choice however Davies, Craig recommend one larger fan, especially for larger capacities engine wise. There will be times, says Davies, Craig, that two will also be fine, however, as an example, a single 16 inch diameter fan will move more air than two 12 inch diameter fans.

What size Thermatic Fan is right for my application?

Size does matter, in fan size and radiator size. It’s pretty easy to work out which size you need. Once you’ve measured the radiator’s height, width, and depth, our website will be able to match the size for the right fan. As a general rule, we recommend the largest fan possible that will fill the dimensions measured above. With a range starting off at 8 inches, with different depths and voltages, there will be an application to suit any engine and radiator size.

Why are the blades on Davies Craig Thermatic Fan straight rather than curved?

Davies Craig invests a lot of time into Research & Development, and testing products has shown that straight fan blades are more effective in moving air than curved blades. It was found that curved blades were overall quieter in performance, but that lack of noise was due to the lack of air being moved by the blades. Also, by using a ring around the blades, Davies, Craig found that straight blades and even wing-tips on the blades kept the air inside the circle, again maximizing efficiency.

Should I mount my Thermatic Fan upstream or downstream of my radiator?

Davies, Craig finds that people are unsure about where to put the fan, ahead of the radiator or behind it. Or, push instead of pull? An important consideration here is where, if you choose to use a push and pull pair, the fans go. Fans should not be fitted on opposite sides of radiator core unless these are offset such that the airflow of one is not interfering with the airflow of the other.

As we head into another hot Australian summer, we also receive several calls relating to the overheating of engines. We have developed a simple checklist that you can run through to help identify the cause of these issues through a process of elimination.

1. Is your fan blade facing wrong direction?
   2. Is your fan blade rotating in the wrong direction?
   3. Is your fan wired to the coil or alternator (not enough voltage)?
   4. No air conditioning condenser fan?
   5. Is your temperature gauge faulty? Does it disagree with thermometer in radiator?
   6. Are you towing a heavy caravan, or similar?
   7. Do you have an inadequate fan kit fitted?
   8. Is the Oil Cooler obstructing the flow of ram air?
   9. Is an insect screen obstructing the flow of ram air?
   10. Are your driving lights obstructing the flow of ram air?
   11. Is your front number plate obstructing the flow of ram air?
   12. Is your Battery/alternator not delivering up to 13+ Volts?
   13. Is there enough water/coolant in the radiator?
   14. Is your radiator dirty? Does it need cleaning or flushing out?
   15. Is your radiator cap faulty, thus allowing water to boil at 100°C?
   16. Is the thermostat faulty?
   17. I the electric Fan motor faulty?
   18. Is your electric fan mounted correctly, in the ‘hot corner’ of the radiator?
   19. Is the engine out of tune, or idling too fast?

So there you have it, the answers to some of our most frequently asked questions as well as a checklist to run through when your car overheats? Do you have a question about our Thermatic Fans, or perhaps their suitability for your application? Use the contact form here to get in touch!

Despite being a common fixture on older cars, air bleed fittings are not common on modern day vehicles. The installation of a Davies Craig air bleed fitting is an added convenience to rid the cooling system of air pockets. Air pockets in any cooling system will ultimately lead to a failure as a result of an overheated engine.

The Air Bleed fitting has been designed to be mounted in the top radiator hose at the highest point of the cooling system. This fitting can be used in conjunction with the Nylon adaptor (part #10415), 3mm Rubber sleeves (part #18510) or 6mm Rubber sleeves (part #18511) for radiator hoses up to 50mm in diameter.

Air pockets are like kryptonite to a correctly functioning cooling system, so if you need to rid your system of pesky air pockets, look no further than our new Davies Craig Air Bleed Fitting.

Can I mix water wetter, glycol and/or anti-freeze products in my cooling system when fitted with an EWP?

Most people are aware that water on its own is not a great thing for keeping cars cool. A question that the Davies Craig service team get asked a lot is about the fluids in a cooling system, such as water wetter, glycol, or anti-freeze products. Davies Craig’s research and engineering have ensured that the EWP range is fully compatible with a mix of liquids thanks to the type of Nylon material used in construction.

How much water pressure can a Davies Craig EWP handle?

Heavy duty applications such as constant towing have our customers ask about high pressure suitability. Davies Craig’s pumps are suitable for most pressure ranges, however if extra capability is needed, a pair of pumps mounted and wired in series will do the trick. A great example is being able to flow a hefty 19 litres per minute, here Davies Craig would recommend a pair of their EWP115 pumps which will flow a higher amount as a slightly lower pressure or pump 19L/min at around 17psi.

Which Davies Craig EWP will best suit my vehicles engine?

One of our easiest questions to answer is about which pump to use for a certain car or even motorbike. With four electric booster pumps starting with the EBP15 for 15 litres per minute all the way up to the EWP150, part of the range of five electric water pumps, all designed to provide different flow rates, Davies Craig will have plenty of options available. Just let our team know which car and engine you have.

What benefits will the Davies Craig EWP give my engine over an existing belt driven mechanical water pump?

Of course, people may be a bit skeptical about the benefits of using an EWP. Straight up, by using the electrical system, engine power normally diverted and increasing fuel consumption doesn’t happen. Therefore the engine works less harder and more efficiently. Also, the fans and water pumps when working together only provide cooling flow when required, not unnecessarily.

Where do I mount the Davies Craig EWP?

Naturally it then begs the question of where an electric water pump gets fitted. Davies Craig recommends a section of radiator pipe at the base of the cooling tower be cut out, with that section being measured to fit the EWP you’ve chosen. This allows the pump to flow efficiently and move with the natural flex and vibrations of the car.

The OUMF run two classic cars, a Riley One Point Five, with one dedicated to rallying, the other to circuit racing. The car itself was built between 1957 and 1965. Davies Craig have stepped in with both cars using their hi-flow EWP-130.

The OUMF teaches students the value of working with minimal resources, minimal tools, and parts. In a psychological aspect, it also forces members to think well outside the box and provide creative solutions.

The 2017 Historic Ypres Rally was one example. The rally Riley had taken a heavy shunt.  Working throughout the night and with that minimalism in mind, it paid off handsomely, with the car repaired roadside, and restarting the next morning. The result was 22^nd overall.

A year later the car entered the 2018 rally after a substantial stripdown and rework. GDM Motorsport had rebuilt the Riley’s cooling system and plumbed in the Davies Craig EWP-130. A rebuilt engine and clutch system was installed. Toyo supplied the R888R rubber and the OUMF Riley, resplendent in its new coat of Lesonal Birch Grey, was rolled out.

Some cog issues were found, and after some overnight work, the team finished 58^th overall from 100 entrants.

The racing Riley was given a new lithium-ion battery which saved nine kilos and powered the Davies Craig EWP-130. This helped the Riley Racer in the Historic Racing Drivers Club opening round at Silverstone.

The Riley completed the warm-up, race, and the drive home, and capped it off by winning their class.

The OUMF with the support of Davies Craig will continue to open doors for those wishing to take their hands from a book and dip them into the well of motorsport.

Don’t let this happen to you! It is preventable with some pre-planning;

• Radiator clean and air passages free of foreign matter, coolant flushed and topped up?
• Check radiator for leaks and that the radiator cap is holding the correct pressure
• Electric engine fan and A/C condenser fan operating efficiently?
• Mechanical water pump not offering sufficient coolant circulation?
• …the list goes on.

Mechanical pumps were designed to be more efficient at idle, but the higher the engine revs the less efficient they become as the manufacturer believes the ram air will be sufficient to assist cool the engine - not so when the engine is under load or you are stationary and therefore a Davies Craig Electric Water Pump, acting as a ‘booster’ may be the answer.

By simply installing the most suitable model Davies Craig Electric Water Pump (EWP) to your engine’s bottom radiator hose you may well solve your engine overheating issue - if you have managed to tick off all of the above.

As you may imagine there aren’t too overheating issues that Australian owned and operated manufacturer Davies Craig Pty Ltd hasn’t had to deal with over the past 48 years!

Depending on your full circumstances, there may be a number of other issues causing your engine to overheat and it’s a process of elimination to work one’s way through each in order to resolve the problem. Clearly when the new vehicle left the factory it didn’t overheat so there has to be a solution.

Nothing is cooler than a cleaned up Small Block Chevy in a classic American muscle car! I had been scouring the internet for some unique (but functional) Small Block Chevy cooling products when I first discovered the offerings from Davies Craig. The EWP and Small Block Chevy Kit (DC-8970 and DC-8621) gave my hopped-up Small Block a fresh new look, while helping it stay even cooler on the street and on the track!

The Chevelle would always run a little warm on the hotter days in SoCal (small block 400’s are notorious for having heating issues). After mounting up the EWP 150, deleting the old mechanical water pump and tying in a Davies Craig 16” puller fan (DC-0166) to complete the setup, the car has never run better. I noticed a more responsive low-end RPM range initially, now that the engine wasn’t plagued with the heavy mechanical fan and water pump. I also noticed a nice improvement in ET at the drag strip. The EWP 150 combination with the 16” fan helped push the Chevelle to its best ET to date, 11.15 at 121mph (over the previous personal best of 11.6 sec @117!).

Also, the cars temps are rock solid when I drive it in the summer months. The EWP and Fan controller knows exactly how to run the EWP 150 and fan, keeping the car always within a few degrees if my desired 170° temp. I am asking a lot of this cooling system with the engines 11.8:1 compression ratio on 91 octane California pump gas, but thankfully over the last 4 years I have yet to have an issue.  

The EWP small block kit really cleaned up the way my engine looks too. Most people I show the engine to, don’t even notice the little EWP tucked away low on the side of the motor. The SBC kit gave the motor a really “race car” look, while keeping the motor cool enough for the street driving, I love to do. 

Davies Craig will be on deck again displaying our award-winning range of automotive cooling products to the enthusiastic crowd, with our marketing manager and classic motoring enthusiast John Benson manning the Davies Craig stand. John’s personal James Dean inspired 1955 Porsche 550s Spyder replica will be on display, demonstrating the installation of a number of Davies Craig products, such as the EWP 130 combo kit and a 14” High Performance Thermatic Fan.

The event runs from the 23^rd-25^th November, with the quarter mile sprint the focal point across the weekend. Come on down and witness some of the best classic cars in the country!

Make sure you have fresh coolant in your radiator

Firstly, ensure that you’re regularly checking you have the correct amount of fresh coolant in your radiator. You will need to also check the consistency of your coolant, if it has thickened or turned to sludge in any way, your radiator will be working overtime. Typically, coolant should last between 12 and 24 months.

Search for any cracks and leaks

Thoroughly search the radiator and surrounding hoses for any cracks or leaks. The hoses should be firm and supple, ensuring they won’t crack during hot temperatures. It’s always worth travelling with a couple of litres of spare water just in case your radiator ever leaks, or cracks and you don’t have access to coolant. And don’t forget to check the radiator cap because a faulty radiator cap will almost certainly lead to water boiling in the radiator.

Pull over if your temperature gauge begins creeping towards hot

At first sight of your temperature gauge rising, you should be looking for ways to cool your car down. The issue may be resolved by driving slowly, or completely stopping to bring the engine back to an acceptable operating temperature. Now this may seem counter-intuitive, although your car will benefit from turning the air-con off and the heater on. Your air-conditioning places a heavy load on your engine and will certainly be contributing towards its overheating. Turning the heater on and pointing your vents out the window works to help manoeuvre some of the hot air from your engine bay away from the overheating parts of the car.

Take It Easy

In summer, it’s important not to put your car through any more stress than it is in already. Be careful not to rev your car unnecessarily or travel for long distances in excessive heat.  Towing a heavy boat or caravan and putting your engine under strain will result in your temperature gauge rising.

Regular Servicing

Servicing your car at the correct intervals outlined in your cars service manual increases your chances of finding any issues before they become big problems. A qualified mechanic is likely to spot small problems that the untrained eye might have missed.

So, there you have it, a few simple methods you can utilise to avoid an overheating engine. Remember, products such as Davies Craig’s range of Electric Water Pumps and Thermatic® Cooling Fans will drastically improve the cooling capabilities of most cars, allowing you to easily monitor and control your engine temperature.

Cooling on the salt flats is one of the more complex issues that teams face as their cars (and bikes) hold maximum RPM’s for 5 miles as they pass through a number of timing gates. The Greenspeed team understand cooling issues on the salt better than most, as back in 2016 they were forced to retire after being unable to keep their intercooler temperatures in check.

The debrief is now underway and the team will be back in 2019 to have another crack at the salt flats.

The adrenaline fuelled event challenged drivers to test their nerve by manoeuvring their high-powered cars around a number of complicated obstacles and scoring points for speed, line, angle and proximity of their cars to the obstacles.

In his 620hp LS2 powered M4, Joachim was able to finish the event in 10^th place. With a host of modifications to ensure suitability for drifting, Joachim also looked to improve the cooling efficiency of his machine and turned to Davies Craig for help. Davies Craig were happy to recommend the application of an EWP150, which functions by pumping 150 litres of water per minute through the 6.6 litre engine.

Joachim next heads to his home track, Rudskogen, for the next round of the Gatbil Drift Series, stay tuned for further updates as the season progresses!

European and Japanese car manufacturers have over the last decade moved towards an electric water pump setup due to the inherent advantages of the product such as increased power and increased fuel efficiency. Unfortunately, as many European and Japanese car owners are aware, the cost of replacement parts on these cars can be quite expensive and the electric water pump is no exception.

This is where Davies Craig enters the picture, we manufacture Electric Water Pumps to suit a wide range of modern car applications by replacing the original, expensive electric water pump. From 80 litres/minute (EWP80) up to 150 litres/minute (EWP150), we manufacture electric water pumps to suit most OE applications.

Are you in the market for a new Electric Water Pump? View our EWP® product page or call us on +61 3 9369 1234 to find out more!

To solve this issue of automotive cooling Davies Craig manufactures a state of the art remote-mounted Electric Water Pump (EWP) in various sizes to suit a wide range of applications. An EWP replaces the iron-age mechanical belt driven water pump, resulting in a more controlled flow of coolant while relieving the engine of the strain of the previous cooling system.

A mechanical water pump has been proven to result in parasitic power losses of up to 10kw – a Davies Craig EWP will immediately re-capture this loss and allow this power to be redirected to the driveline. Additionally, the user will see an increase in fuel efficiency.

When coupled with a Davies Craig LCD EWP®/Fan Digital Controller, a Davies Craig EWP® allows the customer an unprecedented level of control over the engine temperature and operating characteristics of their engine.

With these points considered, the move to ditch the traditional mechanical water pump for a Davies Craig Electric Water Pump is really a no-brainer. For more information on this industry leading technology visit our EWP® product page.

Alan Stoddart is dispatched on a farmyard visit with a difference, discovering students benefiting from front-line engineering experience

TUCKED away down a hidden lane, not far from Oxford city centre, is a small farmyard encircled by sheds, which until not too long ago were dilapidated, with collapsed walls, damaged roofs and dirt floors.

 It is here that the students of the Oxford Universities Motorsport Foundation build, maintain and upgrade its historic race and rally car projects. The foundation was established by students, for students, to provide practical hands-on engineering experience.

 Many of the students in the foundation, who come equally from Oxford and Oxford Brookes universities, feel that they want to supplement their predominantly theoretical courses with oily-fingered and skinned-knuckled motorsport experience. All of this is done on a budget of “effectively nothing”, which means that not only does all tooling and materials have to be, to use the technical term, wangled, but nearly all of the components used on the project cars are supplied by companies that are aware of the alarming skills gap, see the benefit of the foundation’s activities, and want to support it.

 As well as providing sound practice for the engineers who could well end up controlling tight budgets as managers in a cash-strapped race team, these limitations mean that the foundation’s members, in the finest tradition, need to get creative. They must figure out ingenious solutions to be able to hold their own against better funded rivals a good time to put all that theory to the test then. This philosophy also means that any and all ideas are encouraged, and with students continually progressing through the foundation, it means that there are always a plethora of new innovations to consider.

 While their current main project is a British Motor Heritage/Halls Garage-sponsored ‘Sebring’ Sprite race car, the main test beds for all these ideas have been a Mk 2 Golf and a pair of Riley One-Point-Fives, one of which is kitted out for circuit racing and the other set up for rallying. Into the Rileys, which have both been imposingly painted in Lesonal ‘North Korean Racing Grey’, there have gone an astonishing number of modifications and improvements. The engine in the racer particularly has been extensively fettled, with the team even going as far as cutting another engine into slices to be able to look inside and identify where problems may originate, and where advantages be gained.

BATTERY EXPERIMENT

One of the recent experiments has been made possible thanks to SuperB’s batteries. It all started last year when the battery maker decided to support the foundation by giving it one of its lightweight lithium ion motorsports batteries. This in itself was quite an improvement, immediately taking nine kilograms out of the Riley Racer, which weighing in at around 865 kg, is already a big chunk and the single biggest piece of lightweighting the team did last year. However, the team has since switched to a slightly bigger battery from SuperB, which has enabled it to experiment with running the car on a total loss system.

Usually on the ‘B’ Series engine, both the water pump and the alternator are driven by the crank. “THINK Automotive and Davies Craig donated an electric fan and water pump system respectively, which makes the original pump redundant, so with a SuperB battery fitted, the power-sapping drivebelt can be removed,” says Oxford Universities Motorsports Foundation founder Ding Boston.

 One of OUMF’s members, Vlad Ardeleanu, continues: “The thing is, you have some losses through the belt, so we decided to take it off and just run the car off the battery. We calculated the losses through the belt, and worked out how much battery power we’d need to deliver sufficient charge for the length of a race.”

 Impressively, it all worked at the opening round of the HRDC at Silverstone. The car was not only able to complete the warm-up and make it home after a 30-minute race, but the team also managed to win their class. They have since had class wins in both HRDC races at the Donington Historic Festival – running with a belt– so the jury is still out as the research continues. It still remains for the team to see how running total loss affects the all important output figure. Last time the engine was dynoed, it was putting out around 133 horsepower, which is an already significant gain over the engine’s originally quoted 95 hp, but the team is excited to see how the total loss system and other small modifications have changed that figure.

REVELATION

Even things as simple as cleaning the engine properly inside have been revelatory. Looking inside the sliced up engine block, it is possible to see the build up of rust and other deposits in the water galleries, which is impossible to reach manually. It is only by cutting the engine up you can actually get an appreciation for the scale and significance of the rock hard deposits of muck. Additionally, emphasises Boston, “This is on a block that was totally rebuilt around 1800 miles before we got to it. To all intents and purposes this is a block that has been built fairly recently to the best abilities of the engine builder, but look at that build up round the liners and how it might compromise the cooling of the cylinder.”

The solution, he says, is Lenton Treatments. Its unique process, which involves dipping engine castings in a hot caustic solution, is able to get in all of the otherwise inaccessible galleries within the block and bring it back to an as-new condition, without any damage or distortion. “And do you know how much they charge to leave the block as naked as the day it was made? From around 40 quid!” he enthuses. “You try and clean a block as well – which by the way you can’t – for that!”

AWKWARD INCLINATION

A similar story can be told of plugged drill access holes within the block. Cutting open an engine showed that some of these holes were at such an inclination that sediment would gather in them and fill them up to the brim. This is particularly problematic if the engine is subject to any unusually extreme forces, in the event of an on-track knock for example, and all this grot is dislodged straight into the oil. Not good. After identifying the problem, however, the access holes were drilled out and tapped, then grub screws inserted to ensure that they could be thoroughly cleaned in future.

 These incremental gains are endless. The team runs the Riley with an 1860 cc five-bearing MGB engine in HRDC Class B, but during its initial build, they saw the chance to do some lightweighting with a powerfile (no prizes for guessing that tool’s workshop nickname!). Casting marks, unused bosses and even the ‘1800’ engine size digits were removed, all saving around half a kilo. Before it was painted, a student wag cast up a ‘1500’ in epoxy and glued it in place enabling him to boast that the team had the only five-bearing 1500 ‘B’ series engine in existence!

DIMINISHING RETURNS

A good joke, perhaps, but it does show the extent to which the team is having to get creative to further take weight out of the car, one of the areas where the cutting edge skills from university can be very valuable. “What we plan to do soon is a finite element analysis to ascertain where you can safely take more weight from. Andy [an OUMF member and Masters student] is convinced that if you carefully take weight from appropriate points lying outside of a triangle which takes in the crank longitudinally, it can be advantageous and may avoid the drawbacks you might expect,” says Boston.

 “It’s tempting to take a powerfile to a thick part of a casting, but if you took off material from some places, yes you’d lose weight, but you’d also lose critical stiffness. This could cause engine failure through flexing – or we’d need to put a block plate back on to stiffen it all back up again. It’s often diminishing returns when you are trying to lose weight.”

Other gains are more concrete, even if the biggest advantage isn’t necessarily what was intended. This has been the case with the Zircotec coating the team has had put on the Riley Racer’s beautifully crafted BTB Exhaust manifold. While it does do all the things it advertises, like keeping heat from under the bonnet and protecting other components and the paint in the engine bay, the main advantage OUMF has found is that it actually allows the car to be worked on far, far quicker than they could without it. When there is a problem between qualifying and the race, for example, just a few minutes can make the difference between making it back on track or watching the race from the pits. Just by using Zircotec, the team is now able to work on the engine after about two minutes of it being switched off – a very precious benefit in adverse circumstances.

STAGGERING SCRUTINY

Thanks in part to generations of students coming through the foundation, the engine has been subjected to a staggering amount of scrutiny with even specialist balancing company Vibration Free helping to try and iron out the smallest imbalances. Despite this, the foundation’s members still find things don’t always go to plan.

 One of the engine issues the team has had recently has been when switching over to ARP bolts. Boston stresses that ARP bolts are much better and much more reliable than the originals they previously used, but explains that this didn’t stop OUMF’s lack of knowledge causing difficulties. What the team didn’t realise is that the extra torque recommended to tighten ARP’s bolts is sometimes enough to distort the main caps and alter their tolerances.

 This became apparent when the team was invited down to Swiftune’s Kent headquarters to learn the dark arts of ‘A’ series engine tuning from Nick Swift. Before their visit Swift insisted that the team completely dry build the Sebring Sprite’s engine, so that it would just be a question of him having the engine there to check and assemble the component parts. So, diligently, before travelling to Swiftune, OUMF had Owslebury Crankshaft Services machine it ready for Swift to go through it with a fine-toothed comb.

BIG SURPRISE

Well, when OUMF dry built the engine they used brand new standard bolts and bearings and it “spun like a dream”, ABOVE Ah, the glamour! As an unfunded initiative, OUMF is entirely dependent on sponsorship and donations, be they in the form of workshop consumables and tools or finance but having gained the backing of ACL via Engine Parts UK for the bearings, it seemed a good time to make the switch. However, when the ACL bearings went in – which were, on paper, exactly the same size – the crank wouldn’t spin freely. It turns out that the tolerance on ACL bearings is just that much tighter.

 “So that was it, and assembly was put on hold. Nick uses nearby Gosnays Engineering and asked them to help to line bore the block to suit because it was just picking up. It came as a great surprise to us all that the varied torques and tolerances between fixings and bearings from different manufacturers is so specific that even a one thou difference between similar components can create a critical problem,” says Boston.

 “Nick said we couldn’t go any further with it because he wasn’t prepared to put his name to it. I asked if we couldn’t just fettle it? He replied that if there was such a thing as ‘line fettling’, or we were in the paddock with a race to win, then yes, we could, but unfortunately, it’s called ‘line boring’!

 “We were all bowled over by witnessing Swiftune’s attention to detail first hand. When this is coupled to its legendary customer support – and the results his cars get on track – it’s easy to see why the ‘A’ series world beats a path to Nick’s door!” Gains haven’t just been made in the engine though. Right at the front of the car, the grille and other bits of chrome trim, which are no doubt a grand way to adorn the nose, are rather on the heavy side – especially since all that weight is hanging out in front of the wheels. They are increasingly expensive, which is at odds for a team running on the aforementioned shoestring.

 In the HRDC series most chromed bumpers, over-riders, and the like are made of moulded fibreglass. As such the students are presently trying to remake such chrome trim out of ‘lifed’, out of date composites, supplied by ex-OUMF members now working in race teams. All old members are invited to come back and to pass on new skills and experience to the current students, which also allows the team to expand on their very limited experience of working with such materials at university.

MODERN TECHNOLOGY BENEFITS

Soon, they hope that OUMF’s Riley Racer will sport a front grille and other precious and vulnerable chrome trim made from inexpensive materials. They will not only be lighter, but – more importantly – the team will have a mould for the grille and other rare parts should they have an incident which means that they need to be replaced.

 Modern technology and techniques have been adopted elsewhere in the car too. One of the things helping them to develop the car into a really serious racer is the Cartek electrics, and the sensors and data logging system installed with the help of Julian Thomas at Racelogic and Peter Trevor at KA Sensors. This has allowed the team to enjoy similar benefits as better financed professional competitors on the grid, and allowed them to experiment with the set-up of the car when practising and testing. At present, the 2k VBOX must be removed from the Riley Racer for the actual races, but at all other times it allows the students to watch the on-board video and interpret the data plots. By creating traces showing graphs such as speed vs time, and highlighting delta T where time is being lost at key points around the circuit, the team gets a much clearer understanding of what the car is doing.

DATA LOGGING CLUES

“We record everything from air temperature, to brake pressure, steering wheel position, damper movement, the force through the Panhard rod, throttle position, exhaust temperature, and lambda readings,” says Ardeleanu. “It’s a great help to have a lot of data and a lot of practice making sense of it, because you don’t always have the same problem.”

 It can help the team work out whether they need to change something mechanical because it is not behaving as it should, whether changes in set up can be made to accommodate a different driving style, or whether the driver needs to do things differently to get the most out of the car. Moreover, it is great for getting new students involved in the foundation as data logging experience is so important in modern motorsport.

 “Once you explain to a fresher – who’s looking at the Riley as just an old car – that in respect of data it is basically a current touring car, but in granddad’s clothing, you have their attention. And when you tell them they’ve got the chance to play with it and learn all about data logging from all the various sensors on it, they suddenly realise, ‘Wow, this car is really exciting’!” Boston adds.

 A recent additional resource is a rudimentary 3D printer donated by an old OUMF member. It is used to make small prototype components, like brackets, which means that students can now use the CAD skills which they learn every day as part of their degree courses to actually make parts to confirm fit or function, and if the designs are successful they can then be made on the lathe or mill. Having this grade from a 20/50 to a 10/40.

“Most advice about what oil you should run in ‘B’ series engines is a good classic 20/50,” says Boston. “No way! When the team were given a tour of Fuchs’ headquarters in Stoke, followed by a comprehensive lecture, it was explained to them why this is simply not the case anymore. They have worked with us to establish that what we actually needed was 10/40 – not 20/50, or even 10/60. That’s the optimum oil for this particular engine. Maybe not what many people would advise, but for us the difference in reliability has been huge.”

For the students, these modifications and changes, and the accompanying detailed study of the rules, is all excellent ‘real life’ experience and practise for when they embark on their professional motorsport careers. Boston thinks it vital that students learn to develop lateral thinking, and engineering skills and insight to allow them to exploit a situation to the fullest. That is part of what the foundation offers: actual front-line engineering experience.

Ding is, however, very careful about encouraging students in a way which, although sometimes audacious, is never abrasively so. “We joke like crazy about modifying and fiddling about in general, but always with regard to the spirit of the whole sport too. You have to be aware of it and respect it,” he emphasises.

“Creative students continually suggest things that could be done, but the rulebook is their guide, and lines have to be drawn.”

ROLE MODELS

For Boston, this line falls in a place that allows the students to get experience with a car that is beginning to be able to hold its own against far more professional outfits, without taking liberties with the amazing opportunity they have been given by Julius Thurgood (HRDC’s founder and race director). “The point is,” he continues, “that professionals like the Jordans [Andy and Mike of the Jordan Racing Team, one of the HRDC’s most successful outfits] have the means and experience to optimise everything to a far greater extent than we are able to – through relentless practice, data acquisition, and peerless preparation of their own and their customers’ cars. They are fantastic guys and tremendous role models for the students to try and emulate. The students know how lucky they are to have the opportunity to be rubbing shoulders with such respected figures in motorsport, both on and off the track.

 “OUMF is voluntary and self-funded, and obviously everything must take second place to the students’ degree work, so we can’t compete in time or money. But we can try and learn as much as possible from others and make up for it in our ingenuity, relentless checking for reliability, never say die enthusiasm, and the fantastic encouragement of our generous supporters with tools, parts and services. Without these strengths, the students wouldn’t even get a chance to, say, try data logging,” concludes Boston.

 He adds that the team would not be able to function without the level of industrial sponsorship and a supporters’ network which it works tirelessly to maintain by frequent team visits to top motorsport companies like Quaife, TOYO Tires, Lifeline, and NGK. Some, like Bilstein, Helix Autosport, Thermex, Eurolec, and Crossthwaite & Gardiner, work closely with the students, developing products for historic competition cars, and having OUMF members on one-year placements. This gives the students access to, and knowledge of, a wide range of processes – from CNC machining and dynamic balancing, to say, foundries and laminators. Students can find themselves spending a day at G&S learning how valves are made; gas-flowing and building a race head with Dave Crisell at All Stage; or visiting the Pilkington Auto glass factory. It is this mixture of social networking and industry experience which Boston believes sets OUMF apart from any other historic race team or student project in the UK.

 What the team has achieved in its once-dilapidated farmyard is impressive. The tireless building and rebuilding of the car, the stream of students coming through the foundation and their voracious appetite for learning from the very best companies in the business, has meant that the team and its cheerily resilient Rileys have been able to achieve some pretty spectacular results; as have many of the foundation’s growing number of alumni, who are making great strides throughout the world of motorsport.

The lightweight range of Electric Water Pumps are proving to be a revelation amongst the broader automotive aftermarket with their simple ease of installation, exceptional coolant flow, low current draw, lightweight rugged construction.

Davies Craig Electric Water pumps have been available for almost 20 years and while initially regarded as a ‘performance’ product to niche racing markets are now proving to be the lightweight replacement for the age-old mechanical water pump and a broad cross-section of vehicles globally, many of which are becoming very expensive and difficult to obtain. The Electric Water Pump module is a very cost effective way to either a replace, upgrade or for the end-user who has installed their own cooling system and require the EWP® only to complete their cooling package. Davies Craig continues to test and develop all the hi-performance EWP® models with the view to offering the automotive aftermarket another electric water pump alternative.

All Davies Craig’s EWPs® are specifically designed for remote mount universal fitment across a wide variety of engines. Their lightweight, compact design along with their extremely low current draw can vastly improve engine cooling management whilst releasing more horsepower, torque as well as decreasing fuel consumption. Combined with the LCD EWP/Fan Digital Controller, the pump continues to run on after engine shut down thus eliminating ‘heat soak’ and extending engine life.

On a particularly pleasant sunny Sunday, on 17^th June, the OUMF team set off for Belgium on what has become, for the past 7 years, an exciting annual pilgrimage to contest the notoriously tough Ypres Rally. From an observer’s point of view, a trip like any other - but for OUMF, it was a culmination of an extraordinary effort through the previous couple of months.

Having suffered major damage in practice in Ypres in 2017, the car was repaired overnight on the roadside. This emergency work was so effective and to such a standard that the famous OUMF Riley 1.5 rally car was able to not only complete the whole rally, but finished in a stunning 22^nd place Overall. However on its triumphant, and slightly bent, return to the UK, the whole car had to be stripped and painstakingly rebuilt on its year long road to fully repaired recovery. While the body was comprehensively attended to, the full strip down also afforded the team the opportunity to undertake more long-planned mods and improvements too. While GDM Motorsport invisibly mended the beautiful alloy radiator, BTB Exhausts demonstrated their consummate skills too, by the tube bending on the strengthened rollcage. Other upgrades were made to the dashboard, the ultra light and compact Lifeline fire extinguisher system, the wiring (including a ‘superb’ SuperB lithium battery), Schroth Enduro harnesses, our faithful Tillett seat, the steering, and the suspension. In this last department the new dampers, specially developed for the car by Bilstein, and the SuperPro bushes, were to have an almost magical and dramatic effect on handling. The brakes were also upgraded with the generous help of motorsport leaders Performance Braking and THINK Automotive. The shell received a primer coat of Rustbuster 123 Epoxy Mastic, then a final gleaming coat of Lesonal Birch Grey paint preceded a frenetic 4 day build.

As dawn broke at 5am on Friday 8^th June, Dom Norman and the engine rebuild team fitted the new Helix Autosport clutch, installed the engine and gearbox, filled with Fuchs Titan race oils - and it fired up first time! While the unique Pilkington heated screen was being put in, Phillips Tyres were fitting a set of our favorite TOYO R888R tyres.  A couple of unexpectedly complex issues then arose. The first, a bent steering rack, was relatively straightforward to solve, and again it was Phillips Tyres to the rescue as they realigned the car afterwards on their laser tracking rig. However, the cause of a recurring gearbox problem took much longer to pin point, and then - in the absence of any replacement gears being available - involved manually stoning down the cog wheels in the gearbox from 4pm, through the night until 6am. The team worked in shifts for over 13 hours straight! Fingers were crossed, the gearbox reassembled and refitted, sponsors stickers applied to the car - and the Riley just made scrutineering later that afternoon, prior to its pre-Ypres trial at the Abingdon CAR-nival Stages Rally. It went straight through scrutineering, and hardly missed a beat on the day long rally, finishing 58^th overall out of 100 modern rally cars. So - from a bare shell to a stage worthy historic rally car in a week! What an amazing team effort, with all-nighters for many…just like real rallying! All issues arising from the rally were addressed in the next few days to ensure the Riley was as bulletproof as we could make it for the real test in Ypres the following weekend…

On the 17^th June the OUMF convoy headed to Belgium; the OUMF van piloted by Nikita and Ding towing the Riley, and some of the team in a BMW estate driven by James Martin, with Tolga Karabetca, Ben Scothern and Andy Doyle. The others - Bobby Bragg and Niall Geoghegan – followed in a Volvo, with co- driver Ahron Becquart at the wheel. However, even before reaching the A40 out of Oxford, the convoy faced a problem - a tyre on the trailer punctured! A coordinated, pit-lane-worthy wheel change was executed in the middle of the local Sainsbury’s car park, followed by a quick tyre repair at ever helpful Phillips Tyres - and the course was once again set for Ypres.

Despite all efforts, the puncture delay meant that the scheduled ferry from Calais to Dunkirk was missed again this year! Luckily the delay of an hour was not critical to our plans, but the rest of the journey to Ypres was not nearly as exciting as the start! We reached Chris and Patricia Vershaeve’s home in Hollebeke in the early evening, and it was wonderful to see our hosts again for OUMF’s 7^th year here. We all expressed our thanks to them for their hospitality in having us to stay for the whole week ahead, and, as they are avid gardeners, we presented them with a selection of De Witt horticultural tools. The first day concluded with a much-needed dinner in the peaceful central square of Ypres, next to the impressive Cloth Hall, all of which was as yet uncluttered with the rally service park and the crowds of eager spectators. Although it wouldn’t remain so for long…

The next day the OUMF team set up their rally base - for the third year - in a corner of the garage of a local Alfa Romeo specialist, Kris Vanmoerbeke, who once again kindly provided us with space to prepare the Riley ahead of the rally. After unloading and setting things up, we took the Riley into Ypres to introduce the team to another one of our invaluable sponsors, Katrien Verstraete at Lemenu petrol station. She generously said she would provide the team with TOTAL fuel for the rally again this year, and we staged a team photo with her and the Riley on the forecourt.

Tuesday 19^th was mainly spent ironing out the last of the Riley’s problems at Kris’s Alfa garage. In the process of testing driving the car in and around Ypres, it was suspected that the rear bump-stops on the newly-installed Bilstein dampers needed adjusting to allow for optimal damper travel, and this significantly improved the already excellent ride and handling. Another problem that was tricky to solve was that a fuse kept blowing the indicator circuit - but it took ages to find and cure the intermittent short-circuit. In the afternoon, the official Signing on for the event by the OUMF crew, by Ding and Ahron, was conducted at the Ypres Rally HQ near the main square, and we were fleetingly able to thank a very busy Clerk of the Course - Alain Penasse - for his kind help and that of Superstage vzw toward the OUMF team again this year. This was followed by a great barbeque with Chris and Patricia back at their house’s house, during the course of the party they surprised us all with an envelope containing a very generous donation towards the rally entry fees - for which we were all extremely grateful!

During the day, Ding and Ahron spent Wednesday reconnoitering the many rally stages, while the rest of the team made ready for the Historic Shakedown in the evening. We reached the village of Boezinge early to secure a good spot for our temporary OUMF service area, and we set up close to the finishing ramp - a great spot - in the busy main street. The first three runs through the rally stage did not highlight any issues, and the car was performing well. Before the next run, Ding and Ahron reported an odd noise coming from the rear of the car. Being unable to pinpoint the source of the noise, the car was sent out once more. Whilst waiting back at the service area, we received a worrying phone call from Ahron; the Riley had retired from the shakedown after the noise suddenly grew louder. As the Riley still had drive, they nursed it - very slowly - the mile or so back to Kris’s garage. Once assembled there, the team quickly established the source of noise to be the differential, but as it was getting late and dark, we decided to resume the repairs when the garage opened again in the morning.

First thing the following day, while Ding and Ahron continued reccy-ing the stages, the rear axle came off the car and was dismantled - revealing that the bolts holding the crown wheel to the otherwise bombproof 3J limited slip diff had worked loose, and the noise was the heads of the bolts starting to machine the soft aluminium casing. The reason for the bolts coming undone was not clear, but we were very relieved to find that there was no serious damage, and none at all to the 3J LSD itself. At this point four more OUMF members - Dom Norman, Jamie Higgins, Andy Parsons and Vlad Ardeleanu - arrived from the UK to help. The rear axle was completely stripped, cleaned meticulously, and reassembled - with plenty of thread lock and careful attention to accurately torqueing all bolts! Our spare axle provided any small parts needed, while Vlad - architect of the Riley’s wiring - addressed all unresolved electrical problems on the car. The rear suspension of the car was put together again, and the Riley was functional again by early evening - in time for the team to relax watching the shakedown for the modern rally cars, and having an excellent dinner in Ypres.

Friday was the first day of the Special Stages. The day was mostly occupied moving our equipment from Kris’s garage in the van, and setting up at the service park. There were well over 200 cars/teams on the rally so space was at a premium! In order that so many cars could do the first two stages - around 15km each - the rally began in the early evening and continued until late - well after dark. For the Riley, neither of the stages were promising to be easy, and indeed, in service after the first stage, a lack of grip at the rear was reported. Due to the cooler evening, a decision was made to increase the pressure in the rear TOYO R888R tyres by 3 psi. The Riley set off again for the second stage with the remains of daylight quickly disappearing. By the time the car came back it was already dark. Thankfully the car performed excellently, and after swiftly removing the spotlights the Riley was driven to Parc Fermé. The first rally day had been a success; the crew was performing without missing a beat during service times, and the Riley had already climbed to 28^th place Overall…

Saturday consisted of eleven Special Stages, with five services in between them. The Riley performed brilliantly, with no big issues being found throughout the day. Watched by spectators and supporters, the team made a thorough check of each corner and every detail on the car each time it came into service - and at each one the air of excitement grew as Riley made its way further and further up the leader board as competitors crashed and burned.

To great rejoicing, the Riley managed to finish the Ypres historic rally 14^th Overall - 8 places better than ever before - and it was so tricky that only 17 managed to finish at all. I still find it  hard to believe that the oldest car on a rally, competing against cars up to 1993, over 150kms of notoriously rough, tough, narrow Special Stages - came in 14th Overall...leaving, for example, 2 Porsche 911's, 3 Golf Gti's, 5 Mk1/2 Escorts, 2 BMW M3's, plus Toyota Celicas, Opel Kadetts and Asconas - even a Lancis Stratos! - in its wake, or retired, or in the infamous ditches!   

The car that only two weeks before had been a freshly painted shell had finished two stage rallies - one a 2 day international, in a different country! This culmination of a year’s worth of work was a remarkable conclusion to one of the most famous European rallies. To an extent, it can be said that all of the hard work had been done back at the HQ in Oxford, and the dedicated effort of OUMF’s team members had finally paid off on Belgian soil.

This stunning achievement must rate as one of OUMF’s finest performances and reflects so well on an exemplary team, inspiring led this year by James Martin (who starts his career at Crossthwaite and Gardiner this month). However - and as ever - we are all aware that without the wide support of so many supporters and well-wishers across the motorsport engineering industry, this extraordinary adventure could not have happened. It has given such valuable practical experience, education and stimulation to a team whose young members are surely destined to find themselves at the top of the sport all too soon! Thank you all.

Britain is and has been home to numerous famous car brands including MG. Fabled for building a simple yet elegant open topped two seater range of cars, including the beautiful MG B, it’s becoming increasingly common for Davies Craig products to find a home inside the engine bay of such a car. Martin was in need of upgrading the cooling system in his own MG B after a rebuild of the car’s original radiator. Although this on its own was successful, he reported that the three bladed engine driven fan wasn’t up to the task of assisting the new radiator and was concerned about sitting in traffic in summer temperatures, the bane of many 1970s vintage British cars.

With familiarity of the brand stemming from a look around the Davies Craig stand at the 2017 Geelong Revival, the Australian owned brand was the logical choice when it came to finding a suitable solution. The only question that remained was what size Thermatic Fan to go with, 10 or 12-inch? Out came the tape measure and the 10-inch was selected (part #0147).

Crucial to any self-respecting handyman is a set of instructions that are clear, concise, and follow a logical procession. Davies Craig understand that not everyone has a degree in building Swedish furniture, and Martin reports that the level of clarity of the instructions for his chosen fan made installation a breeze.

Martin added a Digital Thermatic Switch (Part #0444) and Universal Fan Mounting Kit (Part #1000). Naturally, being a proud owner, he wanted the engine bay to look as clean as possible. The design of these parts enabled him to tuck them away and remain largely invisible to the casual glance.

The Universal Fan Mounting Kit allows for several mounting options including a “through the radiator” design. This allows a self-installer to bolt through the radiator vanes. This is the route Martin undertook and centrally located the fan directly ahead of the longitudinally mounted four-cylinder engine.

The final steps were to calibrate the thermo probe and switch. Again, Davies Craig’s instructions make this a process that is easy and logical. Some tweaking during testing had the system quickly set and Martin delightedly reports that hard and fast idle testing has the MG B showing no signs of misbehaving.

We look forward to further updates from Martin as the summer months roll in and the MG B gets more extensive use. 

Do you have an older British car that is your pride and joy, and in need of some assistance? Contact Davies Craig via our website to discuss the cooling options to suit your application.

‘Superior performance’, is a well hackneyed phrase in the automotive aftermarket industry. This may not always be the reasoning behind a particular vehicle parts purchase, rather the benefit that comes with the selection of a specific component. Davies, Craig’s Sales and Marketing Manager John Benson stated, “Improved access to the internet along with YouTube videos, websites, Facebook, Twitter, Instagram via mobile phones etc. has given those people who may only have a passing interest in just keeping their vehicle on the road, a broader selection of choices when it comes to the ‘replacement’ of a vehicle’s unserviceable component.”  Benson added, “Davies Craig receives hundreds of emails and phone calls per month from people all around this country and indeed all over the world asking, for advice on replacing their existing OE mechanical water pump for example with an electric water pump or their OE mechanical/electric fan or fan clutch assembly with a Davies Craig Thermatic Electric Fan”. Benson concluded, “Davies Craig has any number of FAQs, etc. videos we even publish our entire range of product Installation Instructions on our website www.daviescraig.com.au so anyone can have access to all the cool replacement products available under the reputable Davies Craig banner”.  

The Davies Craig range of Electric Booster Pumps  were  established to cater for a number of applications including smaller capacity IC engines such as go-karts, motorcycles, small tractors, early thermosiphon engines, water-to-air intercoolers and boosters for car heaters and LPG systems are all common applications among our customers. The Electric Booster Pumps are available in a range of sizes, from EBP15, (15L/min), the EBP23 (23L/min), the EBP25 (25L/min) up to the EBP40 (40L/min).

All EBPs are long-life brushless, magnetically driven pumps. Some models are available in 12v or 24v. Due to their brushless, magnetically driven nature the only moving part is the impeller, which pivots on a spindle and floats in the coolant! The pump’s chambers are hermetically sealed for trouble free operation and endurance.

In a typical performance vehicle’s engine application we would recommend the larger Electric Water Pump to solve cooling issues, smaller engines such as go karts and motorcycles with engines up to 2000cc will benefit from the compact, lightweight EBP.

Talk to us today to find out why a Davies Craig Electric Booster Pump is the solution to your automotive cooling needs!

Formula SAE itself is aligned with the idea of having a business contract a team of students to develop and build a Formula race car. Monash Motorsport themselves have recruited more students to their team, with a Mechatronics and an Electrical Engineering focus.

The Monash Motorsport team, with support from Davies Craig heading towards its sixth year, have been working on two vehicles, a combustion engine and electric engine duo, and will be using these cars in events in Europe such as the Formula Student Germany E.V. Formula Student driving has teams training in aspects of circuit driving and make sure both cars and drivers are up to the task, the test circuits are full of turns. This helps to ensure that the cars are engineered to deal with the physical stress of g-forces at speed.

Following from this is ensuring that the drivers are also capable; three gym visits a week, a seven kilometre run and a one kilometre swim are also part of the regime. On top of all of this are sessions with simulators, programmed to replicate the Australian, UK, and Germany circuits. To assist in the development of the cars the simulators are also programmed to replicate the real world vehicles, meaning the driver’s are gaining practical experience and exposure to the 1:1 scale cars they’ll be racing. The 2017 season showed this effectiveness as there are time penalties for hitting cones on a real track. The simulation sessions had the drivers lapping a second quicker and not hitting any trackside obstacles.

Ruth Li from Monash Motorsports also reports that the team will be finalising presentation details covering Cost Event, Design Event, and Business Presentation Event, with speech rehearsals and marketing material being polished.

Keep in touch with Davies Craig and the news from Monash Motorsport on our respective social media outlets.

Cars are driven through a number of cities and this year’s event sees the Beech Bend Raceway Park in Bowling Green, Kentucky, right in the heart of America’s Deep South, as the starting point. Over six thousand cars and over one hundred thousand spectators will see a bewildering display of automobiles travelling through seven cities including Chatanooga in Tennessee before wrapping up in North Carolina’s Concord at the zMAX Dragway.

Last year’s event enjoyed the company of “DatZen”, a Chev V8 powered Datsun 280Z, and fitted with items from the extensive Davies Craig catalogue. An Electric Water Pump, or EWP, is at the heart of the DatZen cooling system, and being the EWP150, it’s the ideal choice to deal both with the American summer and being part of a miles long line of traffic.

Emily Williams Reeves and her husband built up the Datsun and Chev combination after driving the route for the first time in Emily’s Holden Monaro aka Pontiac GTO a decade earlier.

Emily reports that the car has been at many shows since the 2017 HRPT but of late has been used as a daily driver. Naturally that means the EWP150 has been holding its own in varying driving conditions, however the trio will be joining the Power Tour again this weekend. It’s here that Emily states, with more than a little pride, that it’s the ultimate proving ground for such items as “we literally sit for hours in miles of Hot Rods, where most are overheating and spewing water.”

Emily herself is pretty handy with a spanner, having plenty of mechanic experience. She also co-hosts a car based program with her husband, Aaron, which means that if they need to fit any other Davies Craig parts, it’ll be a pretty simple job for them.

Keep in touch with Emily and Davies Craig via social media and contact Davies Craig for any enquiries on our huge automotive cooling products range.

Mike Drewer, a respected motorsport PR person based in Adelaide, is a shining example of this. We previously reported on Mike’s foray into motorsport outside of PR here: https://daviescraig.com.au/blog/davies-craig-assists-in-cooling-the-vw-beast

And Mike isn’t one for standing still. Well known for his work with the Formula 1 GP when it was Adelaide based, the popular Clipsal 500 event, the Finke Desert Race, and the Supercars event in Darwin, Mike has recently been at the Lake Gairdner Speed Week event where he piloted his Subaru powered 1964 Beetle.

Salt lake driving can be tricky at best, dangerous as well, with the best surface for travelling at high speed also being the best surface for something to go wrong.

A hard, completely dry, flat surface is what salt lakes racers look for, however the salt itself is an unforgiving surface with very little grip that can take a car in a completely different direction to the one the steering wheel is asking for.

Mike himself said: “It's very, very hard but it has virtually zero grip.” Although a terminal top speed is the ultimate goal, getting there takes practice and preparation. It’s not a simple matter of arriving with a car and tramping on the accelerator. This will result in nothing but wheelspin and a salt bath for anyone standing behind the car.

Aerodynamics, tyre pressures, and the correct weight and balance are critical areas of achieving a set top speed. There’s also, engine cooling, of which Davies Craig is a big part of Mike’s quest.

The VW is fitted with a Subaru WRX engine and as such always needs good air and coolant flow. With a goal of reaching over 320km/h at this year’s event, Mike reports that some fine tuning is further needed. Although the desired speeds weren’t reached, Mike did manage runs of over 250km/h in the one way time trials.

The VW itself has been substantially modified. Apart from the estimated 350 horsepower engine, there’s a Davies Craig electric booster pump for getting fluid to the engine’s intercooler. On board are Davies Craig Thermatic fans which are mounted near the car’s radiator.

“Temperatures at Lake Gairdner are very high, so it was very important that we could efficiently keep the engine temperature within the correct range, especially given that we mounted the radiator in a horizontal position under the VW’s front bonnet. Two Davies Craig thermatic fans were particularly effective in providing air flow that exits either side of the car in the front suspension area”

“We faced another challenge with the fluid to air intercooler (charge cooler) mounted inside the car and drawing cool fluid via a large ice filled cold box mounted where the passenger seat used to be. The Davies Craig Electric Booster Pump was perfect for the job with dyno runs proving just how much more horsepower could be achieved with reduced inlet temperatures”.  

“It was a great ‘first time out’ in the VW Subaru and we were awarded the Rookie of the Year Trophy at the 2018 DLRA Speed Week which was very pleasing”.

The car is now in the process of being further modified and improved for its next attempt at Lake Gairdner, known as the “Big White Duno”!       

Keep in touch with us via our social media outlets and keep track of updates for our Speed Week members throughout the year.

The location is a popular one for Davies Craig, and this weekend is going to be possibly the best opportunity to buy some of the latest equipment from this iconic automotive cooling equipment company at discounts of 30%.

This will be a great opportunity to update the cooling equipment in your engine bay, especially if you’re building a performance oriented car for show.

The electric water pump (EWP) range has always been a popular item, and with four pumps to choose from that will flow from 80 to a massive 150 litres per minute they’ll be an ideal addition to the engine bay.

A wonderful complementary item would be a new Thermatic Fan. Designed to replace a failing mechanically driven fan, these 12V or 24V compatible fans can be placed behind or ahead of a new radiator, ensuring maximum airflow for maximum cooling. Pair it with a digital controller and there’s precise temperature control at your fingertips, all at 30% off.

Come and find Davies Craig at booth P053 at this weekend’s Meguiar’s MotorEx and get yourself a bargain!

The event is a favourite of ours and we’ll be bringing along a range of our most popular products including our EWP’s (Electric Water Pumps), Thermatic Fans and our patented LCD EWP/Fan Digital Controller. Our team will be more than happy to help find the cooling solution for your pride and joy, so stop by booth P053 and say hello!

If you’re in Melbourne don’t miss the chance to see some of the country’s coolest cars and attend the nations biggest car show!

But underneath, who looks after the engine, wheels, tyres, and the transmission? Again, a driver can check air pressures, drop in some oil but when it comes to automatic transmissions, a good cooler is required to keep things…well…cool.

Transmissions are like engines and humans in that fluids are required. Autos, especially in the “old” torque converter styles, need fluid to work properly. But just like engines and people, staying cool helps performance, extends life, and increases efficiency. The coolers available from Davies Craig are engineered to help drop temperatures by as much as 33 degrees Celsius and are built to withstand pressures of up to 80 PSI (pounds per square inch). That second one is important as hotter oil expands

Davies Craig can offer two distinct transmission oil coolers; one to deal with pre-1990 vehicles called Ultra, and the Hydra to suit a wide variety of cars. The Ultra cores feature a tube and fin design for transfer of heat of fluid temperature to the air. The Hydra is more compact for tighter spaces. Visually, the Ultra looks like the cooling tubes seen on older fridges with the Ultra the more modern alloy radiator.

There are fifteen distinct combinations available from Davies Craig too. If your vehicle has a 24V electronics system a Hydra 21 plate cooler and fan to suit the voltage can be sourced. With a 20mm thickness, a compact 281mm length, and a fan diameter of eight inches this ensures plenty of air flow and cooling ability. For heavier 24v usage a 30-plate cooler and ten inch fan can be fitted.

The smallest Hydra system for a 12V system weighs just 331 grams so there’s no noticeable impost to a vehicle’s weight. At just 141mm in height, 281mm in width, and with 12 plates plus a near 12000 BTU heat transfer rate it’s an ideal starter for smaller vehicles.

At the other end of the scale is the 23 plate Hydra unit for a 12V system. At just 20mm thick and 281mm long this also fits in easily and is intended for high performance or high workload applications.

The Ultra comes in three size applications to suit a four, six, and eight cylinder engine. Again the physical sizes make for a compact setup, with the largest, to suit an eight cylinder, capable of transferring up to 10,800 BTU per hour.

Depending on the application, Davies Craig would recommend a digital Thermatic fan switch to ensure that the cooler is set to operate at the optimum temperature and within the best operating environment.

Some vehicles are built with transmission oil coolers already, however a driver may intend to use their car for constant towing, or to be used in hilly areas. Farmers in Australia’s arid zones too would benefit from a heavier duty transmission cooler, and with a high corrosion assistance factor engineered in, ensures that just about any working environment can be driven in with plenty of peace of mind.

Naturally all Transmission Oil Coolers are designed for universal fit and include fittings such as hose, appropriate clamps and a quick fit kit to suit.

Further details are available at https://daviescraig.com.au/category/transmission-oil-coolers and if you’re using one already, pleased drop us a line via our social media outlets.

Cooling still requires a radiator but how they’re cooled is changing. From engine driven fans, to fans with a viscous coupling, to fans that are electrically powered and have a sensor to operate them, efficiency is always improving.

There are still plenty of vehicles with a fan that’s powered by the engine itself and have a clutch system that could be close to the end of its working life. Davies Craig recognizes that possibility and offers an easy way to upgrade from a belt driven fan to an electric system.

The systems are designed for easy installation and can be fitted at home once some engine bay measurements are taken.  The height, width, and depth of the radiator needs to be measured, as does the gap between the front of the engine block and the rear of the radiator.

Once these figures are known, the Davies Craig website can be used to help provide the best fitment option for a new thermatic Electric fan. One very helpful piece of information is that one large fan will draw more air through than two smaller units. Another is locating the fan to be fitted as close as practically possible to the radiator’s top outlet, where the hottest radiator fluid will be.

If engine bay space is tight but ahead of the radiator is free, the Davies Craig thermatic fans are reversible. This means that they can pull air through a radiator or push the air through.

Also a little electrical work is required, as current draw figures can determine the maximum electrical fan size. The higher the current rating the more powerful airflow the fan can produce and the bigger the radiator they can deal with.

A mechanical thermatic fan switch is available which operates via a switch fitted into the radiator fluid flow. An electrical service works on a preset temperature that’s set by an operator of the vehicle. This allows more flexibility and fine tuning for specific applications and usage. A dual relay system is also available which will cover a temperature range from 40 degrees Celsius to 110 degrees Celsius.

The Davies Craig website has more information available on converting from a clutch system to a thermatic fan setup.  The website also offers other systems to complement engine cooling systems and our full range of fans to suit anything from a small four-cylinder car to a performance vehicle.

But what happens when they’re neglected and disrespected is also simple. They tend to lose air and that’s not fun when that air escapes all at once thanks to a sidewall fracturing, for example.

Regular viewers of motorsport will be aware of how critical it is to have the right tyre pressure and this applies to our humble family car. Davies Craig offers three aftermarket systems under the umbrella name of Tyreguard that offer a tyre pressure monitoring system or TPMS, with each being designed for both ease of installation and ease of use.  What’s even more appealing is that the kits can monitor not just the four tyres on a car, they can do up to 22 tyres to suit a truck. But what’s the idea behind a TPMS?

Rubber is inherently flexible but in a tyre it needs to be kept at a certain minimum and maximum pressure to ensure that ride quality, handling, and comfort aren’t compromised. Over inflated tyres can have a car slipping, sliding, losing adhesion, and more prone, like a balloon, to having a foreign object penetrate. Under inflation has a car sluggish, harder to turn, and the sidewalls easier to peel off the rim. Fuel consumption will also suffer too.

By using the Davies Craig Tyreguard system these kinds of issues can be minimised and making your journey safer. The entry level iTPMS connects to your Apple device and is aimed at a car driver. The kit includes sensors that will broadcast to a range of up to ten metres, will monitor four tyres, and can be easily fitted inside a few minutes.

The Tyreguard 300 adds Android devices, is made dust and waterproof for off-road applications, monitors all four wheels and comes with both a two year battery life and the ability to measure to plus or minus one pound per square inch (PSI) of pressure.

The third system is the top of the range Tyreuard 400 and is customisable for up to 22 tyres. This one is ideal for truck drivers or caravanners as it will broadcast at a range of up to 7.6 metres in normal trim and up to 16 metres with a booster unit. The pressure range is higher, with a maximum read of 145 PSI. There is also the ability to customise the readouts too, with BAR, PSI, even kilopascals. And for extra peace of mind the Tyreguard 400 will also show the battery charge level on the unit’s display screen.

The kits are available to buy online here: https://daviescraig.com.au/tyreguard-tpms. Don’t forget to follow Davies Craig on social media and keep up to date by following the Davies Craig blog.

There was a minor problem, though. All of those components, in order to do their job, had to be powered somehow. And that somehow was the engine that was meant to be propelling the vehicle.

All of these separate components sap engine power and increase fuel consumption. Nowadays there’s electrically assisted steering, and when it comes to cooling, electric water pumps do the job. The immediate benefit is an increase of cooling efficiency. Mechanically driven pumps turn at the same rate, more or less, as the engine, meaning at highway speeds air speed is also assisting in cooling, meaning energy is being wasted.

An electric water pump weighs less, meaning less energy is being expended to move mass. It also means that using less energy leads to better fuel consumption. Factor in the added benefit of having a controller that reads the engine temperature and adjusts the electric pump’s flow speed according to a number of factors in the system, and keeps the engine’s temperature more accurately where the designers intended.

Davies Craig build electric water pumps to suit a variety of engine size and applications. If it’s a small engine that doesn’t get driven a lot or a thumping V8 in a sports car, Davies Craig will have an EWP to suit. Flow rates from 15 litres per minute up to a Niagara Falls like 150L/minute and to suit 12V or 24V outputs.

Keep in touch with what’s new at Davies Craig via our website and on our social media outlets.

Anyone that’s modified an engine bay will know one of the best options is an aftermarket, electrically powered fan. Davies Craig has a superb range of thermatic fans, available in 12V or 24V compatible units and in varying sizes, designed to replace the belt driven fan your car may have come with originally.

Thermatic fans can be fitted to the front or rear of the radiator to push or pull air through the radiator’s vanes. This flexibility in locating is of immense benefit to motorists wishing to upgrade their cooling systems as it allows a broad range of vehicles to take advantage of the extra cooling ability offered by a thermatic fan.

A thermatic fan works, as its name suggests, via a thermometer activated switch. Powered by the car’s battery, the fan is sent a command to turn on or off once the thermometer’s sensor reaches a set temperature. Consider the holiday traffic jam where slow forward motion is the norm. As a result airflow through the radiator is minimal and by utilising such a system, a thermatic fan raises the airflow level. At highway speeds there’s generally enough air passing through the radiator vanes and therefore the fan is not generally required.

The blades found on Davies Craig thermatic fans are straight, not bent or curved. This has been proven to provide more efficient air flow plus minimizes air flow noise due to a smoother air flow.

Thermatic fans are available from Davies Craig in eight to sixteen-inch diameter options to suit a variety of applications and engine bay sizes. Head over to our Thermatic Fan information page for more on these incredible fans here.

One area that needed close attention was the Subaru’s engine cooling system, “Curly” turned to Davies Craig for some assistance. Davies Craig recommended he install a EWP150 with a LCD EWP/Fan Digital Controller. This installation transformed the machine into one cool Kombi. Total peace of mind when travelling at a slow pace in a convoy of wedding cars or just sitting at traffic lights, slow moving traffic was always fraught with anxiety wondering if the engine temperature was about to go through the roof! Attention was paid to the positioning of the Kombi’s radiators and the routing of the engine’s cooling system to ensure he gained maximum efficiency form the efficient and even coolant flow now being generated by the EWP, the positioning of the Thermal Sensor and strategic use of his LCD EWP/Fan Digital Controller. Davies Craig was eminently qualified to offer Curly assistance as the company had previous experience installing the 2.5 litre Subaru engine in the 1955 Porsche Spyder replica.

Once again Davies Craig has proven that, it isn't only ‘performance’ vehicles’ engines that can be ‘tamed’ from excessive heat. A lovingly cared for Kombi can manage an EWP Combo installation and continue to carry out some excellent work in some of the most trying climatic conditions which the West Australians can experience, just like the Californians, heat, heat and more heat, one of the biggest ‘killers’ of engines! Curly has a range of classic and vintage limousines vehicles that can be used for weddings, parties, hotel & airport transfers, concerts, customised tours of Perth, Fremantle and the Swan Valley wine region and any other social occasion. Way to go, well done Curly!

The Monash team, with backing from Davies Craig now entering its fifth year, are at the forefront of this worldwide initiative and since the New Year ticked over have been working further on design elements such as wing profiles, using materials (hard and soft) in testing to look at what shape and which kind of material provides the optimum profile and downforce at speed. There’s also 3D printed items that are being evaluated.

The students recently unveiled a new undertray for one of their design projects, one of a pair of vehicles known as M17-C and M17-E as part of the development work. C for Combustion, E for Electric, of course.

 In an exciting time for the team, both cars have been invited to compete at the 2018 iMech Formula Student UK, Formula Student Austria, and Formula Student Germany E.V. events This will pit the Australian team against some of the best in their field from European universities.

Part of the lead up to taking the cars overseas is, naturally, track based testing. Early February and the first week of March saw the Monash Motorsport F-SAE crew venture to the beautiful Victorian seaside town of Warrnambool. This puts to a practical test the work that the students and lecturers have performed.

And in a late piece of news that again will bring Monash Motorsport to the fore, they’ve been invited to develop and produce a fully autonomous vehicle and to test that car at the Formula Student Germany trials.

Keep in touch with Davies Craig and the news from Monash Motorsport on our respective social media outlets.

As a result of the extensive research program, Davies Craig were able to conclude that curved blades generated less noise, however, this was achieved at the expense of a significant loss in performance. The loss in performance is caused by the fact that curved blades stall at a lower static pressure than straight blades. If a fan moves less air, then simply, you can expect less noise. As shown in the performance curves below, Davies Craig Thermatic Fan outperforms a competitor’s curved blade product across the full pressure range: 

Noise Control: Most fan noise is generated from a blade passing a shroud strut. The noise level is higher when the whole length of a blade overlaps/passes a shroud strut and if all the blades pass all the struts of a shroud at the same time, noise is at its worst. Some manufacturers have chosen to curve the blades and keep the struts straight. Since this approach significantly affects performance, Davies Craig has proven it's best to adopt the reverse approach of having straight blades and curving the struts.

Our investigations also found that when air flowed in layers (laminar flow), it breaks up into counter rotating airflow vortices (whirlwinds): 

These vortices consume energy and therefore reduce the airflow. It was found that by inserting triangular protrusions near the leading edge of the blade, the air is tripped into going into vortices earlier. The resulting vortices were much smaller and removed much less energy therefore making the blade more efficient. The idea of a ring around the blade tips was also researched and rejected since the performance suffered due to the increased energy required to propel the blade with extra weight at the tips. While the purpose of a ring is to reduce losses from air passing from the high-pressure side of the blade to the low-pressure side as shown, Davies Craig managed to achieve this by adding winglets to the blade tips without energy loss. 

When all aspects of blade design are considered, straight blades with trips, winglets and the correct shroud is the optimum, test-proven combination for efficient fan operation. 

British based attorney John Crowhurst is one member of a very select group who had similar thoughts to the builder of that car. John, formerly based in South Africa, has found an engine that comes from the same basic aeronautic background, however it’s a British built Merlin engine.

During WW2 the Merlin engine powered planes such as the iconic Spitfire. Rolls-Royce sourced parts from engines that had been in crashed aircraft with the hope of being able to use them for something else during the war. A home was found for the project by using these parts as the basis for an engine that was called Meteor.

The Meteor engine was built for and used in tanks and was in service until 1964. One of these has been repurposed to be the power plant for a hand built car that John, sadly, can’t legally drive on UK roads.

It’s a V12 configuration, something that fans of Jaguar or Aston Martin can appreciate. But it’s the capacity that gives pause for thoughts. Consider for a moment that a Holden 5.0L engine was 308 cubic inches. John’s beast is 27.022 litres or a whopping 1648ci!

Naturally something this big needs a good (great?) cooling system and John has fitted a set of tanks that have a total of 70 litres worth of fluid capacity. This is where Davies Craig has joined the party. Two Davies Craig EWP150 Electric Water Pumps, were sent to John and both installed, one at the rear and one at the front end for the radiator.

The car itself is built on a ladder chassis with tubular components  forming the upper body structure. It’s strong but flexible enough to deal with the 631 horsepower and 1449 lb-ft (470 kW and 1964 Nm).

John is naturally quite happy with this although laments that, in his extensive sponsor list, he doesn’t have a fuel supplier. Why? At around 100 km/h or 60 mph it uses a litre of fuel every mile.

At least it won’t overheat thanks to the two Davies Craig EWP150 Electric Water Pumps!

Davies Craig offers electric water pumps which are far more efficient across a broader range of driving situations than mechanical water pumps. Not only do they provide a more even and consistent coolant flow rate in slow moving traffic conditions on hot days, by eliminating the mechanical energy drawing component required to operate them, the EWP will release extra horsepower and decrease fuel consumption. For example, the EWP150 (Electric Water Pump, 150 litre/40 gallons per minute) suits an engine of 5.0 litre capacity and above, and is even suitable for drag racing and other motor racing applications. At the other end of the electric pump and booster spectrum is the compact Electric Booster Pump (EBP15) at 15 litres/min.  This tiny unit is ideal for motor bikes, scooters with engines up to 1100cc capacity and suitable in vehicle heater/cooling systems.

In order to provide the most efficient coolant flow for all conditions a LCD EWP/Fan Digital Controller or a Thermatic Switch is essential.  The LCD EWP/Fan Digital Controller calibrates engine coolant flow and controls temperatures. The Thermatic Switch will target which temperature the EWP or Fan is to be engaged. Both units will engage and cut off at pre-specified temperatures so, for example, if out on a freeway run with minimal traffic, normal airflow through a radiator will manage keeping an engine cool. However, once the vehicle slows or stops, the engine temperature increases and the LCD EWP/Fan Digital Controller will engage the Davies Craig Thermatic Fan/s. At this point the EWP will be operating at maximum flow and both the fan and EWP will continue the cooling of the engine.

A driver can to set the Digital Controller a targeted/preset temperature. At +3C the fan will engage offering increased cooling in most conditions. To ensure the LCD EWP/Fan Digital Controller is operating as expected there’s onboard diagnostics which constantly monitor the Controller’s own performance and sound an audible alarm if any issue has been sensed.

Switches come in either mechanical or electronic forms. The Mechanical  Switch (part #0401) is basic in concept, with a probe mounted inside the radiator hose and the unit wired to the vehicle’s ignition system. Again, once a set/targeted temperature is reached, sensed from the probe it powers on the fan.

A Davies Craig Electronic Switch (part #0444) uses either air or water temperature as a starting point. The temperature at which it’ll engage a fan can be preset to assist in cooling when required. Also it can be set up to run two fans if and when required. Davies Craig manufactures units to suit both 12V and 24V electronics.

We’ve compiled the checklist below to assist you select the most suitable Thermatic Electric Fan for your vehicle.

1. Measure your radiator core dimensions (width, height and depth, from the front of the engine to back of radiator) and compare these dimensions to the specific models of Davies Craig Electric Fans. 
2. Davies Craig Thermatic^® Fans are reversible (Ex: Brushless models) which means they can be mounted either upstream or downstream. (illustrated below)
3. In general, one large fan will have better airflow than two smaller fans. Where the radiator is rectangular or space is tight there may be no choice but to fit two smaller fans; choose the largest fan that can be accommodated in space available. The fan can also be mounted offset from centre of the radiator to clear engine components when mounted in the downstream position.

1. If possible, mount the fan directly to the radiator core and as close to the hot water inlet as possible for maximum cooling efficiency.
   Note: Fans should not be fitted on opposite sides of radiator core unless these are offset such that the airflow of one is not interfering with the airflow of the other.
2. If you require advice, please contact Davies Craig for further assistance.

Both cars are running a Davies Craig EWP130 to increase the cooling of their engines, with immediate success realised in the form of increased power outputs and higher rev allowances.

At Davies Craig, we are overjoyed to be playing a role in the education of young engineers and wish the team all the best in their endeavors throughout the coming year.

Davies Craig has been a longtime supporter of Norm and the Big Knob Racing Program, who are the pioneers behind Australia’s fastest Hot Rod. Their 1934 Ford Roadster is kept cool by two Davies Craig EWP150 Electric Water Pumps, one for each side of the block to even out coolant flow and control engine temperature. Additionally, dual Davies Craig 14” High Performance Thermatic Fans (1500 CFM each) are fitted to the rear mounted Aussie Desert Cooler radiators. This package ensures the super-fast roadster is capable of maintaining constant temperature levels despite the harsh natures of dry salt lake racing.

After coming perilously close to the 200mph mark in 2017, the team returns in 2018 with hopes of cracking the 200mph barrier for the first time since Bonneville Speedweek in 2016. We wish Norm the best of luck out on Lake Gairdner and look forward to providing you with an update upon his return.

Since our last update, the team took part in the 2017 Formula SAE Australasia competition, sweeping both the internal combustion and electric categories against some very strong competition. Each car was ranked on a number of criteria including design, endurance, acceleration, skid pad and efficiency among others.  Congratulations on an incredible result!

Headlining the team’s efforts in 2018 will be trips to Europe for Formula Student Germany, Formula Student Austria as well as Formula Student UK. Stay tuned to the Monash Motorsports page for more information on the upcoming events!

After another fantastic event, the team can’t wait to make their way back in 2018!

Unlike other pumps, the EBP does not feature any brushes to wear out, rather being driven magnetically by the motor, meaning that no shaft sealing is required. There is only one moving part, the impeller, which is floating in the coolant.

Davies Craig’s range of EBP’s are available in flow rates from 15 L/min (4gal/min) up to 37 L/min (9.8 gal/min) at 12 & 24 volt. Designed with universal fitment in mind, the EBP can be used to compliment a vehicle’s existing mechanical belt-driven water pump utilising a simple, DIY installation. The pump chamber is hermetically sealed for trouble free operation. The ease of installation, low current draw, high flow capacity and long life makes the EBP ideal for a range of applications.

Cooling on the salt flats is essential to a fast run, with engines running at rapid rpm’s for 5 miles at their absolute peak speed there is a lot of heat running through each and every competitors power plants. Team Greenspeed understood better than most the risks associated with overheating on the salt flats, in 2016 the team was unable to keep rising intercooler temperatures in check.  For 2017, the team returned to the flats with a pair of EWP150’s bolted to their engines.

The most interesting part of the Team Greenspeed project is their aspiration of becoming the world’s fastest vegetable oil powered car. Unfortunately in 2017 it wasn’t to be, as the late delivery of a new camshaft put any vegetable oil related dreams on hold. For the event a traditional common rail engine was subbed in and the diesel pickup truck record was beaten soundly!

We can’t wait to see what the team at Greenspeed has in store for 2018 when they take to the salt again!

On display will be Davies Craig’s full range of Automotive Cooling products, including our reigning SEMA Global Media award winning 14’’ Brushless fan and display LS engine, which demonstrates the brand’s EWP LS Adapter Kit.

The event once again takes place at the Las Vegas Convention Center from October 31 – November 3, we will be located at booth number 37213, which is located inside the Upper South Hall. Make sure to stop past and say hi!

Davies Craig will be attending the World Time Attack Challenge on October 13-14 at Sydney Motorsport Park in New South Wales.

Previously, Jonathon has provided us with some fantastic feedback on our product since installing it a couple of years ago, and continues to reap the rewards of a state of the art automotive cooling product. Once again Jonathan’s 240z ran incredibly throughout drag week, negotiating the extended travel while laying down some insane quarter-mile times with ease.

See the below photos of the 240z which were taken by car photographer extraordinaire Larry Chen throughout drag week.

Mechanical water pumps are a belt driven pump that runs in conjunction with the operation of the crank, giving the cooling system extremely little flexibility in maintaining an optimal operating temperature. This is particularly of issue in situations where engine coolant is pumped through an engine excessively, thus wasting horsepower. The parasitic power loss can be up to 10Kw and an Electric Water Pump will allow this power to be redirected to the driveline.

By releasing the strain on an engine that a mechanical water pump inflicts, the installation of an EWP® will result in an immediate increase in power and improved fuel efficiency. A Davies Craig EWP® is operated totally independently of the engine, drawing very little DC current at maximum flow, allowing coolant to be pumped at precisely the correct flow. When coupled with a Davies Craig LCD EWP®/Fan Digital Controller, a Davies Craig EWP® allows the customer an unprecedented level of control over the engine temperature and operating characteristics of their engine.

With these points considered, the move to ditch the traditional mechanical water pump for a Davies Craig Electric Water Pump is really a no-brainer. For more information on this industry leading technology visit our EWP® product page.

Hot August Nights is held in Reno, but not in one central location, the event is spread out all over the city! It’s about the cars, and the classic car lifestyle, something we can’t get enough of. We met attendees from as far away as Canada and Australia who came to this event just to experience it. Every night, after the show was over attendees would line up along the main streets of Reno to watch the hundreds of classic cars cruise up and down the closed off streets.

Davies Craig was exhibiting the product range inside of the “Big Boys Toy Store” along with dozens of other automotive aftermarket companies. The product range was received very well, selling out incredibly fast, while we also met a handful of customers who already installed the product on their cars.

We also had the chance to officially introduce the Davies Craig Product range to some very large players in the US cooling world so all in all the event was a roaring success. Bring on 2018!

After initial shakedowns both cars were able to log approximately 30km on the track, an impressive outing first up! As in previous seasons, the 2017 combustion engine car will feature both a Davies Craig 9” Thermatic Fan and EWP80 Electric Water Pump. We are incredibly excited to play a pivotal role in getting some of the nation’s brightest young minds out on the race track in some truly innovative machinery.

The Monash Motorsports program is ultimately working towards the FSAE National competition that will be held at Calder Park in late November. While plenty of testing and R&D is to take place between now and then , after such a promising initial shakedown the team is sure to be on the pace come November.

Watch the two videos below to see how the initial test day at Oakleigh panned out, including a clip of the Electric car being powered up to 80kw (107hp)!

We heard countless stories from people who had installed Electric Water Pumps in their hot rods and street rods to eliminate overheating issues. Garnering the most attention throughout the event was the new LCD EWP and Fan Digital Controller, with its endless adjustment possibilities and groundbreaking “after shutdown run-on” feature that helps to avoid heat soak. So many street rod enthusiasts struggle to keep these rolling pieces of art cool on the street, but with the help of the Davies Craig EWP, Electric Fans and LCD Controller the job has become a whole lot easier. 

We even ran into a customer who had recently installed and EWP on his classic car. He had been encountering serious overheating issues to the point where he couldn’t even drive it. With his newly installed EWP the car was able to easily negotiate the 5 hour drive between Illinois and Kentucky.

You can next see Davies Craig on US soil for the iconic SEMA event, which runs from October 31^st to November 3^rd, we can’t wait to see you there!

My new 13b pp engine is a bit of a beast and generates a lot more heat than the smaller 12a extend port. My next step in upgrading my cooling system was to upgrade the radiator from the stock unit to a larger Proflow alloy radiator. This was a direct bolt in unit and measured the same dimensions in height and width as the stock radiator however the core was near double the thickness.

While we had the radiator out we figured this would be the perfect time to contact Davies Craig and upgrade to one of their electric water pumps and car controller. Davies Craig also sells top quality cooling fans so we matched up 2 x 13” fans to our new radiator. Best of all, the in car controller not only looks after the electric water pumps speed and flow but also controls the radiator fans. This is an awesome setup which I have known about for some time however I must say now I have been using it myself it really has exceeded all of my expectations. The in car controller monitors your water temperature and is able to set the flow rate of your electric water pump and can switch between a slow pulse right up to full speed flow. It also cycles the fan speed on the radiator fans too. All of this works together to keep power usage to a minimum and your car nice and cool even when sitting in heavy traffic in summer.

Another thing I like about this is the fact I was able to remove the belt driven water pump from my engine. Since I have no aircon and no power steering and no belt driven pump, the only belt driven accessory on my engine is my alternator. This has taken a lot of strain off my engine and also means less potential belt slip. I am now looking at ways to do this same electronic water pump setup on my turbo 2JZ as it really tidies up the look of the engine. The only problem is the 2JZ and 1JZ water pump setups are quite complicated if removed. I would need to have a series of block off plates with -12 or -16 AN bungs welded on so water is still re-directed as it exits and then goes back into the correct places on the engine block, all while still keeping clearance behind the belt that runs the cam gears. If only it was a nice and simple setup like my rotary engine which was just one single block off plate with 2 x –16 AM bungs welded on. One for water in and the outer for water back out to the radiator.

When running the new cooling lines I decided to use some nice -16 braided hoses and ProFlow -16 AN fittings as supplied by Racers Ink. Even though this was a fair bit more expensive than going the cheaper rubber hoses and stainless clamps I now have virtually no chance of a water leak. Everything is very tidy and easy to keep an eye on and I never have to worry about checking any hose clamps to see if they have loosened off. The other bonus is they match my fuel lines and fittings so my engine bay is starting to look really good.

The last part of the cooling system upgrade was the custom fabricated alloy radiator shroud which was welded up and fitted by CCC only two weeks before they unfortunately closed their business.

Although I did opt to spend a bit more money here and there on different parts I am really, really happy with how everything came together with my new water cooling system. My RX7 now runs at a perfect temperature all year round. I forgot to mention, the Davies Craig in car controller even works like a turbo timer. You can switch your car off and it will keep your fans and water pump running until it detects that your water temperature has dropped back down to a safe level. You can set the desired temperature yourself. This way it is suitable and customisable for a supercharged big block V8, turbo 4cyl, rotary or any size motor at all.

My setup was so good that our other staff member Daniel Ryan decided to get the exact same setup on his 13b BP Mazda RX7. The only difference with his system was he went with an alloy PWR radiator, black -16AN fittings and some really nice black braided hose. He now swears by this setup and wants to do it to his other cars too, something I certainly agree with. Feel free to come and say hello if you see either of our vehicles at an event. We are more than happy to show you and explain how it all works in person.

The customer supplied an existing mechanical water pump housing with the fan drive shaft and impellor removed. The top and bottom radiator hoses were then removed and retained for use during the EWP installation. The viscous fan clutch and blade as well as the radiator, the existing mechanical water pump and thermostat housing were removed.

After removal, the radiator was sent to Aussie Desert Coolers to have mounting lugs welded into the outer frame to accommodate the mounting of the Davies Craig 16” Thermatic Fan. Using some of the existing bottom radiator hose, the EWP130 Electric Water Pump was fitted. The modified mechanical ware pump housing and the thermostat housings were bolted to the block, while the Digital Controller’s Thermal Sensor was placed in the top of the radiator hose. The LCD EWP/Fan Digital Controller was mounted under the dashboard along with the LED warning light.

Along with the wiring and relays, the radiator with its newly mounted 16” Thermatic Fan was reinstalled. At this stage it was imperative to ensure that all the air was removed from the entire cooling system before being filled.

Stop by our stand and check out our range of Electric Water Pumps, Electric Fans and Digital controllers. We will also be running a number of show specials so be sure to get yourself a great deal on one of our award winning products. We can't wait to see you there!

The two chassis were on view on the night along with the 2016 Formula SAE race car – which has a Davies Craig 9” Fan on the rear of the radiator and a EWP80 Electric Water Pump in lieu of the mechanical pump. The Formula SAE internal combustion engine in 2017 will be a KTM 690cc naturally aspirated motorcycle engine. The engine will be unmodified, except for the water pump, of course! The radiator will once again carry a Davies Craig 9” fan. In the past the engine capacity of these internal combustion racers had been limited to 600cc and Hondas were the engine of choice. The KTM engines are significantly lighter, stronger and have excellent torque which is pivotal in the various styles of events these race cars are required to compete.

On hand to answer questions about the brand new chassis were the various design teams, fabricators, suspension and aerodynamic personal. Formula SAE race cars are coming quite sophisticated in their suspension, chassis engineering and aerodynamics with a strong emphasis on chassis strength, reducing weight and ride height. These factors have become critical elements to succeeding in this form of motorsport. Over the past few years there has been a significant shift towards electric vehicles; however both classes are still very well supported around the world by tertiary institutions. Davies Craig is proud to be involved in such a technologically sophisticated category of racing and we can’t wait until November to see how the team fairs at Calder!

DatZen’s life started back when Emily’s husband Aaron bought the 1978 280Z to be used as his daily driver. After 10 years of marriage and 10 years since their first Hot Rod Power Tour (which was made in Emily’s GTO), the two decided to build up the 280Z and recreate the trip they made 10 years earlier. The LS delivers in the vicinity of 360hp to the wheels and from all reports is incredibly fun to drive! Emily has told us that the Davies Craig EWP150 has provided the car with awesome cooling capabilities and has drawn a tonne of attention from fellow Hot Rod Power tour Participants!

The Davies Craig Electric Water Pump (EWP) is a lightweight and more efficient alternative to the iron-age power sapping mechanical water pump. When coupled with the accompanying LCD controller, the EWP provides unparalleled control over the cooling capabilities of your car. The speed of the pump is managed by the controller, which varies the supply voltage to the pump and so varies the speed of the pump, hunting for a target temperature. When the engine reaches the target temperature the controller locks on, constantly changing the pump speed with traffic and throttle conditions, maintaining the target temperature independent of the engine speed.

My project began back in 2009 and as part of that, I set out to solve the problems of space and poor air flow in the engine bay for a large cubic capacity Ford V8 in a tight engine bay. Space constraints meant running a traditional engine fan was simply not possible and would also not generate the kind of air flow through the radiator and back over the engine required for effective cooling. Thermatic fans were certainly not new and Davies Craig were a natural choice for me.

The Nagari was always prone to bay heating and heat soak which would make re-starting a hot engine difficult.

Solving that brought the relatively new Davies Craig electric water pump and computer controller to my attention. I saw this as real opportunity to solve a number of problems with a single solution.

In the end I went a step  further, by also installing a Davies Craig hot water booster pump to deliver coolant through to the heater core.

On the road, the cooling system performed flawlessly managing the coolant temperature setting and varying only a few degrees as the Davies Craig system adjusted to speed and conditions. The system manages the water pump and fans interactively and after engine shut down runs them on for short periods to solve the problem of heat soak.

Recently, because of a move to much warmer climates in Western Australia, and as a precaution only, I upgraded to the latest Davies Craig water pump and computer.  This pump moves a larger volume of water ensuring that temperature management is further improved.

As a bonus, the new pump is more compact taking less space required in a tight engine bay.

My faith in Davies Craig was hardly a stretch as Davies Craig were long experienced and product quality was a given.

Personally, I would never build an engine without including a Davies Craig cooling system solution.  As a mark of that, I also cool my 9.2 ltr Detroit Diesel powered motorhome using Davies Craig products.  The Davies Craig fans have allowed me to replace the engine driven fan saving 25 horsepower and the fuel necessary to drive that.

My thanks to John Benson and the Davies Craig team.

Automotive Electric Fans offer a more efficient, energy-saving alternative over a fan clutch or belt-driven mechanical fan. A fan clutch is never fully disengaged; it keeps on spinning at approximately 30% of the water pump speed at all times. The fan clutch will also limit how fast the fan can rotate and only turns the fan at a fraction of the water pump speed, depending on engine speed and temperature.

A significant advantage to the Davies Craig Thermatic Fan is the recovery of parasitic power losses. As a result of the fashion in which mechanical fans operate, power will be lost. The Davies Craig Electric Fan will release these losses from your engines power, thus increasing power and improving fuel efficiency, making it a great option for standard and performance vehicles alike.

The benefits of straight fan blades v curved fan blades has been a constant point of discussion amongst automotive enthusiasts over the years. However there is no doubt about it, whilst potentially louder, straight fan blades provide a significant performance benefit over the curved competition.  The loss in performance is caused by the fact that curved blades stall at a lower static pressure than straight blades. If a fan moves less air, then simply, you can expect less noise.

Davies Craig are the market leaders in Automotive cooling in Australia, our range of Thermatic Fans, Switches and Electric Water Pumps have revolutionised the industry. Australian owned and produced, Davies Craig can provide you with the automotive cooling solution you desire.  

There’s nothing quite like fitting and road testing your own engine cooling products to a special vehicle to evaluate and show their versatility! On Start-up, the LCD EWP/Fan Digital Controller, set at 85 degrees Celsius, the EWP performs its 10 second system check function. As the engine temperature rises, the 14” HP Thermatic Fan switches on when the temperature reaches 3 degrees Celsius above the targeted temperature, pulling 1500CFM through the radiator! The EWP130 and Thermatic Fan perform as designed, the EWP operates at full flow from 80 degrees Celsius, and the fan kicks in at 88 degrees Celsius and turns off when the engine temperature drops below 80 degrees Celsius.

When the engine has been shut down by the operator, should the temperature be higher than 85 degrees Celsius, the EWP and fan will continue to run until temperature drops 10 degrees Celsius below the targeted temperature. Should the temperature rise again, after shut-down, the EWP and fan will kick in again as designed – very reassuring!

The Beck 550s Spyder is an attractive and unique vehicle, has been displayed to practically demonstrate the Davies Craig LCD EWP/Fan Digital Controller operating the Electric Water Pump and Thermatic Fan effectively and efficiently to potential purchasers.

Speedweek is an annual event that takes place on Lake Gairdner, where hundreds of racers converge to lay down blisteringly fast runs on the salt.

After losing fuel pressure, then melting a piston at Speedweek 2016 on a 212 mph record run, the roadster’s engine needed a rebuild. Mat bored out the big block Ford and de-stroked it giving the Big Knob Roadster a motor that revs to 9500 revs recommending gear changes at 8500 revs resulting in power figures of 920hp and 730 ft lbs of torque.

So it was with these new modifications that the team made their way to central South Australia for the 2017 running of Speedweek in early March. After a number of changes over the last 12 months, the crew did an excellent job prepping the car; with zero issues being found during tech inspection.

Unfortunately, Run 1 didn’t quite go to plan for Norm at the helm of the hot rod, encountering issues with the rear end moving around, ensuring the 194mph pass was just a tick off what was expected. After changing up the rear tyres for run 2, the team encountered further bad luck.

“Back on the track for my second run, this time the back end felt ok so I decided to go for it. But the motor wouldn’t agree; it didn’t want to pull past 7000 revs. I dropped back a gear to see if the revs would come up. They didn’t…. then the low fuel pressure light came on - and stayed on. I hit the kill switch but it was too late.” Norm said afterwards.

Unfortunately, the week came to an end early for the team after finding a dent in the sump that had been pushed out from the inside, so back to the garage it is!

As Australia’s leading manufacturer of automotive cooling products, Davies Craig is looking forward to what 2018 holds for the Big Knob Racing team!

This chopped VW has a sting in the tail via a Subaru WRX turbo engine and gearbox whilst being fitted with a water to air intercooler. This monster is being built with only one purpose in mind!

Its destined for the salt lakes in outback South Australia (Lake Gairdner to be precise) to compete in speed record runs conducted by the Dry Lake Racing Association (DLRA) that has become a magnet for high speed vehicles in much the same way as Bonneville in the USA.

Owner Mike Drewer who admits to being on the “wrong side of 60” says the project is his last fling in motor sport competition and was brought about by a combination of a passion for VWs and land speed record attempts.

‘My father had a VW when I was a kid and I also saw the Donald Campbell Bluebird Land Speed Record Car paraded in Adelaide after it had done 400mph plus on Lake Eyre back in 1964’.

While the little VW isn’t being built with that speed in mind, somewhere between 150 and 200mph ‘would be quite an achievement’, Drewer (who used to race Australian Formula 2 open wheelers) believes.

The car build has been undertaken by Simon Richards at Rickos Road and Race in Adelaide and commenced with finding a couple of old beetle bodies and a good floor pan.

‘It’s been quite a job with the six inch body chop, extending the wheelbase, installing an IRS rear end, constructing the roll cage, making a custom fuel tank, installing the on-board fire extinguisher system, making a parachute mount, building the coil over suspension, mounting a Wilwood competition pedal assembly and Kirkey race seat and full harness, and installing the Subaru WRX drive train’.

The engine is to be fitted with larger injectors and turbo monitored by an Autronic ECU and Motec data logging dash, while the gearbox has been converted back to a 2WD unit by Subarugears. X-Force Performance Headers will be fitted. 

The radiator and barrel intercooler are PWR units and Davies Craig thermos fans are mounted downstream on the radiator core which is placed horizontally where the original VW fuel tank was in the nose of the vehicle.

The passenger seat area now features a large ice box with internal copper coil for the Davies Craig electric booster pump to supply super cool fluid to the intercooler.

A Davies Craig electric water pump is also being contemplated for the vehicle which is nearing its build completion.

‘We still have to give it a ‘rat rod’ style paint job, obtain the Goodyear speed record tyres and set the car up with a heap of castor to achieve good directional stability. Then it’s a matter of dyno work on the engine, and plenty of test runs at a local airport’.

‘We won’t get to Lake Gairdner until next year, and then I guess I will see if I can still drive fast in a straight line!, Drewer joked.

Stay tuned for more news on this totally unique VW-Subaru.

Peter Allen, the owner of the magnificent Matilda, notified us recently of the paddleboat’s ability to travel for four hours at an ambient temperature of 38⁰C with engine temperature remaining constant at 82⁰C and oil pressure at 42psi. Peter went on to explain that previously to fitting the Davies Craig EWP80 and an external oil cooler, engine temperature’s would have been much higher whist oil pressure would have been significantly lower! Once again, the Davies Craig EWP has come to the rescue of an engine suffering under the burden of the iron-age belt-driven mechanical water pump.

The EWP80 is a simple, easy to install product that has been designed to complement or replace the existing belt-driven, mechanical water pump. It will fit most vehicle makes and models fitted with naturally-aspirated or turbo engines up to two-litres. The revolutionary EWP 80 is made from anti-corrosive, lightweight, heat-resistant, glass-filled nylon and incorporates a ceramic faced seal for long-life durability. The EWP80, as well as all other Davies Craig EWP’s is designed and built locally in Australia.

Whilst affording you even greater cooling control, the EWP80 will allow you added power and improved fuel economy. By removing the parasitic power loses of a belt-driven, mechanical water pump, the EWP can provide you with up to 10kw of extra power and increased torque.

Entrants are restricted to a 600cc motorcycle engine meaning there are only so many things to be done to differentiate themselves from the pack. Formula SAE engines are required to perform at high RPM’s during competition, whilst maintaining the ability to respond and accelerate very quickly. This style of competition renders itself as the perfect opportunity to utilise innovative and groundbreaking products.

Traditional mechanical water pumps will typically sap an engine of around 3-5kw, however an electric water pump such as the EWP80 allows a Formula SAE entrant to regain this power whilst saving fuel and weight. The EWP80 is a simple, do-it-yourself, remote-mounted Electric Water Pump that’s anti-corrosive, lightweight, heat resistant and incorporates a ceramic faced seal for long-life durability. Many competitors will also use Davies Craig Thermatic Fans on their vehicle’s radiator to achieve extra cooling on these high revving machines. 

Davies Craig EWPs have been on the market for 18 years and continue to provide both competitors and the general road user alike with an Australian made product that provides substantial benefits over traditional means of automotive cooling. When coupled with the Davies Craig LCD EWP & Fan digital controller, the EWP is the most efficient way to cool your engine! Click here to find out more about the Davies Craig EWP range.

Sophisticated new cooling systems enable the internal combustion engine to operate at higher temperatures with far greater efficiency. The innovations also provide more precise thermal management required for fuel cell and hybrid power train systems.

These smarter cooling systems feature rapidly evolving technologies: high performance electric water pumps, such as Davies Craig’s Electric Water Pumps (EWP)®, patented LCD EWP/Fan Digital Controller and Electric Booster Pumps (EBP®) to complement speed controllable Thermatic® Fans thus reducing parasitic power loss which is achieved by controlling and varying the coolant flow rate commensurate with engine temperature and independent of the engine's speed. This vastly improves performance in demanding motor racing applications. Importantly, it can also provide heat soak protection and continues coolant circulation and air flow even after the engine is switched off.

Engine management systems are evolving rapidly, and thermal management systems are adapting to keep pace. The performance, efficiency, and environmental benefits provided by the enhanced cooling system technology provided by Davies Craig Pty Ltd are compelling. These advantages will no doubt become even more crucial as environmental regulations continue to increase, along with consumer demands for more fuel-efficient, higher horsepower vehicles.

There are some significant horsepower and torque gains should the mechanical water pump and mechanical fan be removed and replaced with a Davies Craig EWP® Electric Water Pump and Electric Fan. Depending on the cubic capacity of the engine many owners have either blanked off the mechanical water pump or removed the impellor/s and mechanical fan. Either way the mechanical water pump will operate in unison with any model EWP® and vice versa. Extra horsepower and better throttle response will be achieved if you remove the impellor/s or the water pump entirely.

The latest addition to the Davies, Craig Electric Water Pump EWP® cooling technology range is the alloy EWP®150 Electric Water Pump. This high tech product offers unsurpassed cooling efficiency for medium to high capacity engines. The alloy EWP®150 is a more compact, lightweight (only 2lbs), which delivers a flow rate of 40 gal/min (150 l/min). The unique compact design of the alloy EWP®150 allows for easy remote fitting in a tight engine compartment on the bottom radiator hose. The inlet and outlet sizes are 1½” (38mm) and both have internal AN-16 threads to enable end-users to adapt screw-in fittings if required. With the efficient low current draw ‘pancake’ motor built into the alloy pump body, the EWP®150 offers a cooler environment in which to perform. The EWP® motor is kept cool by the engine’s coolant as it passes through the pump’s volute chamber thus producing excellent air-free coolant flow and operating temperature for all conditions. The unique Davies Craig LCD EWP®/Fan Digital Controller will manage the performance of both the Electric Water Pump and Electric Fan. This patented Controller, which becomes the engine’s new ‘thermostat’ will manage the coolant flow commensurate with the engine’s temperature and will automatically turn on the fan at +3°C above the set/targeted temperature, which is normally set at the manufacturer’s thermostat temperature for efficient operation.

All Davies Craig Electric Water Pump Combo Kits come complete for simple do-it-yourself ‘plug and play’ installation, with a comprehensive booklet of instructions.

As a result of the extensive research program, Davies Craig were able to ascertain that curved blades generated less noise, however, this was achieved at the expense of a significant loss in performance. The loss in performance is caused by the fact that curved blades stall at a lower static pressure than straight blades. If a fan moves less air, then simply, you can expect less noise. As shown in the performance curves below, Davies Craig Thermatic Fan outperforms a competitor’s curved blade product across the full pressure range: 

Noise Control: Most fan noise is generated from a blade passing a shroud strut. The noise level is higher when the whole length of a blade overlaps/passes a shroud strut and if all the blades pass all the struts of a shroud at the same time, noise is at its worst. Some manufacturers have chosen to curve the blades and keep the struts straight. Since this approach significantly affects performance, Davies Craig has proven it's best to adopt the reverse approach of having straight blades and curving the struts.

Our investigations also found that when air flowed in layers (laminar flow), it breaks up into counter rotating airflow vortices (whirlwinds): 

These vortices consume energy and therefore reduce the airflow. It was found that by inserting triangular protrusions near the leading edge of the blade, the air is tripped into going into vortices earlier. The resulting vortices were much smaller and removed much less energy therefore making the blade more efficient. The idea of a ring around the blade tips was also researched and rejected since the performance suffered due to the increased energy required to propel the blade with extra weight at the tips. While the purpose of a ring is to reduce losses from air passing from the high-pressure side of the blade to the low-pressure side as shown, Davies Craig managed to achieve this by adding winglets to the blade tips without energy loss. 

When all aspects of blade design are considered, straight blades with trips, winglets and the correct shroud is the optimum, test-proven combination for efficient fan operation.

The EWP80 is a simple, do-it-yourself product designed to complement or replace the existing belt driven, mechanical water pump. The water pump is anti-corrosive, lightweight, heat resistant and incorporates a ceramic faced seal for long-life durability. The benefits of an electric water pump are in its enhanced cooling control capabilities, added power and improved fuel economy. Davies Craig is proud to play such a pivotal role in a form of motorsport that often serves as a stepping stone between karting and professional racing.

Davies Craig has been a strong supporter of the Vintage Adventurer, who tackled the 2016 Great Rattler Run armed with a Davies Craig Electric Water Pump, Digital Controller and 16" Thermatic Fan. When asked about the performance of the Davies Craig products throughout his arduous journeys, Rod had the following to say:

“The Davies Craig products together with the Lucas Oil Water Wetter are a wonderful combination. The Electric Water Pump is brilliant and many people have been sneaking a look under the bonnet to see why I can run so hard in the head winds and heat. Top speed on the black stuff was 140kph before I realised and backed off. When we have ram air I actually turn the EF off in order to retain some heat in the engine.”

Being an Australian owned company, Davies Craig relishes the opportunity to support such an inspirational concept. We look forward to continuing our support of the Vintage Adventurer and can’t wait to see what he has planned for the future!

A Davies Craig Thermatic Fan features straight, fully reversible blades to enable mounting on either side of the heat exchanger, ensuring suitability for both pusher (upstream) and puller (downstream) applications. Davies Craig Thermatic fans operate totally independently and are controlled by a Thermatic Switch which can be adjusted to engage at your engine’s thermostat opening temperature for maximum cooling effect.

Follow these simple steps to convert your current setup to a Thermatic® Electric Fan

• Measure your radiator core area, width and height.  Also, check to ensure there is enough depth (distance between the front point of your engine block and rear of the radiator)
• Check these dimensions against the appropriate Davies Craig Thermatic® Fan listed in the catalogue or on our website daviescraig.com.au
• Choose the largest diameter fan that you are able to fit to the core of your vehicle’s radiator. In general, one large fan will have stronger airflow than two smaller units
• Fans can be mounted off-set from the radiator centre. An electric fan will be more effective when mounted as close to the hot water inlet (top radiator hose) as possible
• All Davies Craig Thermatic® Fans are reversible which means they can be mounted upstream (in front of the radiator) or downstream (behind the radiator)
• Examine the Thermatic® Fan specifications and examine the airflow (CFM) and maximum current draw. The higher the current rating the more powerful the fan. A more powerful fan can draw air through multi row radiators and air conditioning cores.  The high flow, lower current fans function well on single core radiators

Your engine needs air just as much as you or I, so don’t settle for any less than the best! Davies Craig are an Australian owned and operated company at the forefront of automotive cooling technology.

Firstly, our engineers simply removed the one-piece grille from the BT50 to enable us to gain access to the radiator. The A/C condenser was uncoupled and swung out of the way. We drained the cooling system by removing the bottom radiator hose and retained the coolant in a container. We removed the plastic fan cowling attached to the radiator that surrounds the fan blade. We ensured the radiator was empty of coolant and then removed the radiator.

The radiator was then removed to gain access to the fan clutch hub. The centre hub nut was simply unscrewed. A special pulley holder was made in house and this was used to remove the clutch fan pulley.

We proceeded to remove the factory-fitted viscous clutch fan hub. At the same time the hub nut was replaced. You will note the factory serpentine belt was not disturbed and the original belt configuration retained to ensure the water pump could be driven correctly.

With the radiator out of the vehicle the team installed our Davies Craig 16” Thermatic® Fan (part #0166) to the rear of the factory radiator with the Universal Fan Fitting Kit (part #1000). As these fans leave the factory in a ‘pusher’ (upstream) configuration, the team removed the circlip from the front of the blade, removed and reversed the blade then replaced the blade on the shaft along with the circlip. The team reversed the 16” blade before installation to ensure a strong positive air flow is delivered with the fan positioned in the ‘puller’ (downstream) position.

The radiator was reinstalled and the top and bottom radiator hoses were secured. The cooling fluid was poured back into the cooling system. The engine was started and run up to operating temperature. Once the system cooled down the cooling system was checked and topped up with the same coolant.

The Mazda BT50 was road-tested and run up to operating temperature. On return all hose fittings and mountings etc. were checked for tightness and security.

Since the conversion the vehicle has travelled over 5000 kilometres and performed faultlessly, keeping the engine temperature in a comfortable heat range with the assistance of the Davies Craig Premium Thermatic® Switch (part 0455) installed with this fan.  

Firstly, a short rundown on the pitfalls of traditional mechanical water pumps. Mechanical water pumps have been used in cars for decades; however, they are one of very few remaining antiquated systems on a modern day car. A mechanical water pump is a belt driven pump that runs in conjunction with the operation of the crank. This gives the cooling system little to no flexibility in maintaining an optimal temperature as the higher the engine revs, the more water is pumped through the engine. This will often result in the engine being cooled either too much or too little. Another downside to the nature of mechanical water pumps are the resulting losses in power and fuel efficiency, the more water that’s pumped, the more power that’s sapped from the engine.

Due to the nature of Electric Water Pumps utilising electricity as opposed to mechanics, when running an Electric Water Pump you are likely to experience gains in power output, torque, fuel efficiency and throttle response. An electric water pump is operated totally independently of the engine drawing very little DC current at maximum flow, allowing for water to be pumped at precisely the correct speed. Throughout testing, Davies Craig has discovered that a mechanical water pump will use up to 10kw of power to operate at high speeds. The addition of a Davies Craig Electric Water Pump (EWP®) will recover this 10kw, sending most of it through to the wheels, with a small amount being lost throughout the drivetrain. When coupled with a Davies Craig LCD EWP®/Fan Digital Controller, a Davies Craig EWP® allows the customer an unheard of level of control over the temperature and operating characteristics of their engine whilst also eliminating heat soak.

Make sure you have fresh coolant in your radiator

Firstly, ensure that you’re regularly checking you have the correct amount of fresh coolant in your radiator. You will need to check the consistency of your coolant, if it has thickened or turned to sludge in any way, your radiator will be working overtime. Typically coolant should last between 12 and 24 months and vigilance is essential in ensuring you won’t encounter any issues.

Search for any cracks and leaks

Thoroughly search the radiator and surrounding hoses for any cracks or leaks. The hoses should be firm and supple, ensuring they won’t crack during hot temperatures. It’s always worth travelling with a couple of litres of spare water just in case your radiator ever leaks or cracks and you don’t have access to coolant. Whilst searching for any faults with the radiator, ensure the radiator hose isn’t faulty. A faulty radiator cap will almost certainly lead to water boiling in the radiator.

Pull over if your temperature gauge begins creeping towards hot

At first sight of your temperature gauge rising, you should be looking for ways to cool your car back down. The issue may be resolved by driving slowly, although it may take completely stopping to bring the engine back to an acceptable operating temperature. Now this may seem counter-intuitive, although your car will benefit from turning the air-con off and the heater on. Your air-conditioning places a heavy load on your engine and will certainly be contributing towards its overheating. Turning the heater on and pointing your vents out the window works to help maneuver some of the hot air from your engine bay away from the overheating parts of the car.

Take It Easy

In summer, it’s important not to put your car through any more stress than it is in already. Be careful not to rev your car unnecessarily or travel for long distances in excessive heat, both of which are likely to result in your engine temperature rising. Towing a heavy boat or caravan and putting your engine under strain will result in your temperature gauge rising.

Regular Servicing

Servicing your car at the correct intervals outlined in your cars service manual increases your chances of finding any issues before they become big problems. A qualified mechanic is likely to spot small problems that the untrained eye might have missed.

In conjunction with the above, there are a number of basic factors that may be contributing to your car overheating, such as your fan blade rotating or facing in the wrong direction. Your temperature gauge or thermostat could be faulty, or maybe your number plate, driving lights, or bull bar are obstructing ram air.

So there you have it, a few simple methods you can utilise to avoid an overheating engine. Remember, products such as Davies Craig’s range of Electric Water Pumps and Thermatic® Cooling Fans will drastically improve the cooling capabilities of most cars, allowing you to easily monitor and control your engine temperature. When it comes to automotive engine cooling and solutions, Davies Craig is an industry leader in design, quality and innovation.

An automotive electric fan offers a more efficient, energy-saving alternative over a fan clutch or belt-drive mechanical fan. Considered a step-up as Thermatic® Fans are lighter, release parasitic power from the vehicle’s engine, expends spinning a fan clutch and/or a belt-driven mechanical fan.

Davies Craig has extensively examined the on-going aftermarket potential and has elected to move out of this specific fan clutch market. On the other hand, Davies Craig automotive electric Thermatic® Fans operate totally independently and are controlled by a Thermatic® Fan Switch which can be adjusted to engage at your engine’s thermostat temperature opening for maximum cooling effect.

Follow these simple steps to convert your current setup to a Thermatic® Electric Fan

• Measure your radiator core area, width and height.  Also, check to ensure there is enough depth (distance between the front point of your engine block and rear of the radiator)
• Check these dimensions against the appropriate Davies Craig Thermatic® Fan listed in the catalogue or on our website daviescraig.com.au
• Choose the largest diameter fan that you are able to fit to the core of your vehicle’s radiator. In general, one large fan will have stronger airflow than two smaller units
• Fans can be mounted off-set from the radiator centre. An electric fan will be more effective when mounted as close to the hot water inlet (top radiator hose) as possible
• All Davies Craig Thermatic® Fans are reversible which means they can be mounted upstream (in front of the radiator) or downstream (behind the radiator)
• Examine the Thermatic® Fan specifications and examine the airflow (CFM) and maximum current draw. The higher the current rating the more powerful the fan. A more powerful fan can draw air through multi row radiators and air conditioning cores.  The high flow, lower current fans function well on single core radiators

Don't short-change your engine’s cooling system. Short term gain could develop into long term pain as your cooling components are the most vital parts of your engine’s cooling system. Davies Craig Thermatic® Fans are proven leaders in the automotive and air-conditioning fields.

Depending on your full circumstances, there may be a number of issues that could be causing the engine to overheat and it’s a process of elimination to work one’s way through each in order to resolve the problem. Clearly when the vehicle left the factory it didn’t overheat so there has to be a solution.

If the engine has been modified to increased horsepower in various forms, this could be a contributing factor. Some of the issues listed below may appear to be very basic and elementary but you may be amazed how many of these actually fit the profile of an overheating engine.

We suggest you go through each, crossing them off as you go…

1. Fan blade facing wrong direction
   2. Fan blade rotating wrong direction
   3. Fan wired to coil or alternator (only 8 Volts)
   4. No air conditioning condenser fan
   5. Temperature gauge faulty - disagrees with thermometer in radiator
   6. Towing a heavy caravan
   7. Inadequate fan kit fitted
   8. Oil cooler obstructing ram air
   9. Insect screen obstructing ram air
   10. Driving lights obstructing ram air
   11. Number plate obstructing ram air
   12. Battery/alternator not delivering 13+ Volts
   13. Insufficient water in radiator
   14. Radiator needs cleaning/flushing out
   15. Radiator cap faulty allowing water to boil at 100°C
   16. Faulty Thermostat
   17. Electric fan motor faulty
   18. Electric fan not mounted in ‘hot corner’ of the radiator
   19. Engine out of tune or idling too fastLack of a circular radiator fan blade shroud
   
   

Finally, you may find the mechanical water pump may not be offering sufficient coolant circulation at the higher engine revs while towing. Mechanical pumps were designed to be efficient at idle and the higher the engine revs the less efficient they become. As the manufacturer believes the ram air will be sufficient to assist cool the engine, this doesn’t always happen when the engine is under load and therefore an electric ‘booster’ pump may be the answer.

By simply fitting a Davies Craig Electric Water Pump with the LCD EWP/Fan Digital Controller (EWP Combo Pack) to your engine’s bottom radiator hose you may well solve your engine overheating issue - if you have managed to tick off all of the above.

The Tomcar Australia story is a wonderful example of passion and persistence by the Brim family company to bring their ATV to market. Driven by a strong desire, the fruits of their 5+ years of ‘hard R & D labour’ reached a point where local company MTM Industries offered them assistance to mass-produce this product in Victoria.

“Davies Craig is proud to be associated with the supply of Australian-produced Thermatic® Fans to Tomcar Australia. An exciting addition to the Australian ATV market, Tomcar is set to blaze a trail across this great Aussie landscape and tackle target markets including Agricultural, Defence, Mining, SES, CFA, Police, Surf Rescue just to name a few”, commented John Benson. “We support young enterprising Australian companies like Tomcar Australia and as a 40-year innovative Australian start-up company it’s in our DNA to get behind the Brim family and support their company reach their objectives”, John Benson concluded.

The past eleven years have been a battle for Tomcar to cement its place in the challenging Australian Manufacturing industry and the very competitive ATV market. The Melbourne-based ATV-maker has been steadily establishing its presence with its expanding range of high-end, off-road vehicles that have found a strong footing in the agricultural industry. The company has also developed models to suit the military/defence, law enforcement and mining. The company is well down the track with development of its electric LV1 go-anywhere vehicle which should create a strong interest from a number of machinery and automotive sectors.      

Davies Craig Pty Ltd has been a strong supporter exhibiting at the PRI Show over the past decade. Approx 80% of the performance type aftermarket businesses, including the engine builders, chassis manufacturers and race teams are located within a 600 mile radius of Central America, Indianapolis and therefore gravitate to the PRI Show. Along with our US partners 3pConnect, Davies Craig will continue to forge relationships with major warehouse distributors as we consolidate our position as a solid, creditable supplier of our Electric Water Pumps, patented LCD EWP/Fan Digital Controllers and Thermatic Fans to this burgeoning automotive aftermarket! 

Davies Craig demonstrated a LS engine, featuring our EWP LS Adaptor Kit, and the very innovative LS Intercooler designed by 417 Motorsports, which uses our EWP150 Electric Water Pumps to ensure their intercoolers stay full of circulating coolant. This display created quite a good deal of interest generating much discussion amongst the SEMA visitors to our booth. We plan to add a clear Perspex radiator and have an operating EWP on this engine display for the PRI Show first week December. We also had a 40” HD TV playing videos from each displaying brand, including Davies Craig EWP install videos and commercials throughout the whole show.

We had visits from a good number of high profile Warehouse Distributors who have expressed a solid interest in taking on our excellent range of engine cooling products.  

Overall the 2016 SEMA show was an outstanding success for Davies Craig and we can look forward with some excitement as we work through the very positive list of potential customers!

Davies Craig headed to Sydney for one of the biggest spectacles on the annual motor sport calendar, the World Time Attack Challenge. This motor sport activity is extremely popular around the world, especially Japan and the top Japanese competitors brought their high-powered cars to Sydney to compete!

The Davies Craig booth was buzzing with excitement as a huge number of spectators poured into Sydney’s Motorsport Park to see the action. Most of the top competitors have a Davies Craig EWP® fitted to their engines. In the final analysis the top five competitors’ engines were each  fitted with a Davies Craig Electric Water Pump!

The weekend was action-packed as up to 200 competitors competed in a variety of classes in this two day shoot-out to determine who would be the fastest around Eastern Creek raceway. In the final shoot-out it was Australia’s Tim Slade and Bart Mawer who took the first two podium honours with Japan’s Under Suzuki filling third spot.

The weekend was hugely successful on a number of fronts. A good number of happy customers went home with their new Davies Craig Electric Water Pump Combo Packs! Some purchased Davies Craig Thermatic Fans and even purchased Tyre Pressure monitoring Systems! Check out daviescraig.com.au for the complete range of world-leading engine cooling products.

Davies Craig is still on the hunt for our dearly missed Ilinga AF2 Sports Car! We created two back in 1974 and although one is currently being displayed in the Melbourne Museum, the others whereabouts are currently unknown.

Our Ilinga AF2 was created using aluminium body panels over a steel chassis featured a modified 4.4 Litre V8 engine from Rover that was upgraded to put out an astonishing 220hp, a strong figure even by today’s standards.

With its unique design and enormous sentimental value, we would be thrilled to find the second vehicle. If you have ANY information that could help us find it, please contact us on (03) 9369 1234 or email us: info@daviescraig.com.au

So what’s the solution? Well a Davies Craig Electric Water Pump (EWP®) of course! An electric water pump is operated totally independently of the engine drawing very little DC current at maximum flow. This allows the EWP® to operate at precisely the right speed, with a Davies Craig patented LCD EWP®/Fan Digital Controller fitted to give you the desired engine operating temperatures. Now, a EWP® is more efficient and more ‘in tune’ in with your engine's specific cooling requirements.

Having a Davies Craig EWP® provides more horsepower, improves throttle response, fuel efficiency and even extends your engine's life by eliminating heat soak! So when things are getting hot under the hood, you can count on a Davies Craig EWP® and LCD EWP®/ Fan Controller to save the day!

Davies Craig is an industry leader in design, quality and innovation when it comes to automotive engine cooling and solutions. Proudly Australian owned and operated, we have been manufacturing and distributing world class Electric Water Pumps and Thermatic Cooling Fans® around the world for over 45 years.  

That’s why we are excited to announce our new Low Coolant Level Alarm Kit that eliminates potential damage and worry by alerting the driver that coolant has reached a dangerously low level. This warning provides the driver with enough time to take preventative action before over-heating and significant engine failure occurs.  

Our Low Coolant Level Alarm Kit monitors the level of the coolant in the engine and notifies the user if any undesired drops in level occur. A loss of engine coolant can cause the water pump to lose pressure and can quickly overheat the engine. If a radiator hose frays, splits or begins to leak and the engine’s coolant is either low or lost, a temperature gauge will not be enough to alert the driver. This is where the Low Level Coolant Alarm adds security to assist in monitoring your engine’s coolant level.

The device features three choices of audible alarm patterns and the ability to trigger louder external alarms such as your car horn. The digital monitor can be easily mounted in the driver’s compartment and provides vital information regarding coolant level and even voltage. The Nylon Inline Sensor Adaptor simply fits into the top radiator hose of your engine and won’t produce electrolysis.

Our Low Coolant Level Alarm Kit consists of;

• Compact Electronic Alarm Module – Dimensions, 120 mm x 80 mm x 25 mm
• Mounting Pad
• Nylon Inline Sensor Adaptor
• Wiring Looms x 2
• Hose Clamps x 2
• Rubber Sleeve Adaptors 3 mm (1/8”) x 2
• Installation Instructions

So it is no surprise to hear that one of Australia’s first unique luxury sports coupes was created by none other than Davies Craig’s own Daryl Davies. Daryl partnered with engineer and race car driver Tony Farrell to develop an incredible luxury automobile that Australia could call its own. The cars name envisioned a prosperous Australian automotive industry with the word “Ilinga” meaning “Distant horizon” in Aboriginal.

The Ilinga AF2 was created using aluminium body panels over a steel chassis with a rigid passenger cell that was strengthened by three roll bars and crumple zones. The car featured a modified 4.4 Litre V8 engine from Rover that was upgraded to an astonishing 220hp, an incredibly large figure in its day, so large that the Borg Warner transmissions failed to cope with the additional power.

The key goal of the project was to create a genuine luxury sports car and in doing so featured all kinds of electro wizardry such as a digital clock, automatic seeking cassette player with radio, a delay switch to turn off lights and lock the door if the driver had forgotten to do so, air conditioning and even electric windows, quite a list for a car produced in 1974!

The business had plans to create 100 cars per year but fell short after being confronted with the loss of their local engine supply source and the early 1970’s fuel crisis. Only two Ilinga AF2’s ever made it from the factory and one has been proudly displayed at the front of Melbourne Museum for over 40 years, but unfortunately the other cars whereabouts remains unknown.

The Ilinga AF2 truly captured Australia’s automotive passion, it is a shame there are not more examples in existence today, on a positive note however we are glad that part of the Ilinga’s genius is still pushing automotive boundaries with Davies Craig’s cutting edge cooling products and solutions.

If you have information that could lead Davis Craig to the location of the second Ilinga AF2 Sports Coupe, please contact us on (03) 9369 1234. Also keep an eye out on the Davies Craig Facebook for the upcoming “Search for the Ilinga” promotion.

These high-revving, high speed demonstrations while offering fantastic entertainment generate an extraordinary amount of engine heat and the mechanical water pump is not adequate! So much so that Kent’s Mustang engine temperature was off the scale at Adelaide’s Clipsal 500, demonstrations, overheating constantly.

So, some action was needed!

Enter Melbourne based Ford performance professional Herrod Motorsport and well established Australian manufacturer and engine cooling specialists Davies Craig. These two companies put their heads together and came up with an engine cooling package that solved this problem. Kent Dalton’s Hot Wheels Mustang was shipped directly to the Thomastown premises after the Clipsal 500 to undergo the Davies Craig EWP150 Combo Kit and Adaptor Kit installation.

Armed with one of the prototype Davies Craig’s Ford Coyote EWP Header/Adaptor Kits and a EWP150 Electric Water Pump Combo Kit, Davies Craig’s Sales and Marketing Manager John Benson headed to Rob Herrod’s Thomastown premises to arrange the installation. The team at Herrod Motorsport were up to the task and the Hot Wheels Mustang was duly fitted out ready for four days of hard-charging drifting work at the Albert Park, Australian F1 Grand Prix circuit.

Dalton’s Hot Wheels Mustang will be drifting around most of the V8 Supercar Championship circuits this season. These Ford 5 litre coyote engines are fast becoming the engine of choice amongst the new Ford Mustang owners in Australia accounting for over 80% of the power plants fitted to the newly released Ford Mustangs.

The addition of the Davies Craig  Electric Water Pump Header-Adaptor Kit, coupled to the EWP®150 Electric Water Pump Combo Kit not only frees up the parasitic power loss inherent with mechanical water pumps and also offers a more consistent coolant flow!Deleting the existing mechanical iron-age water pump from the front of the engine block also frees up space, allowing the fitment of high performance 14” or 16” Davies Craig Thermatic® fans! 

Herrod Motorsport is best recognized for its high performance work on Fords. Rob Herrod’s team has had a close involvement in most Ford one-off specials over the last decade and tackling the Mustang’s engine temperature issue was all in a day’s work. This exciting new product allows end-users to enjoy the benefits of the superior engine cooling technology that Davies, Craig’s Electric Water Pump (EWP®) and the LCD EWP®/Fan Controller Combo Pack offers.

Jonathan Foster from FosterZ Performance (USA) was only too happy to share with us his success and positive feedback running our Electric Water Pump (EWP150) on his Datsun 240z powered by an LS based engine, this street car is possibly the fastest LS Swapped 240z in the world. All while being driven thousands of miles a year!

Just letting you know I went to race over the weekend and managed to reset the world record for an S30 with an LS motor in it.

Did a 8.2 @165 but had a fuel pump fail mid pass. Luckily my ECU kept the motor alive haha.

I also drove home that night (80 miles) and drove the car about 250 miles in traffic and freeway conditions without a hitch. The Electric Water Pump (EWP150) seems to have no issue keeping up with my setup. (Highest I saw was 205 in bumper to bumper traffic, which is likely due to my HUGE intercooler. I plan on doing some air guiding on the car before drag week, but I'm confident that the cooling system will be fine.

The Electric Water Pump did a great job of cooling the car off after making passes as well, I'm super happy with it. Just wanted to thank you again for giving me to opportunity to run it.

Thanks again for your help!

I’d like to share my experience with the refilling of the engine cooling system after we fitted the Gates blank mechanical water pump (part 43548X1) and Davies Craig Pty Ltd EWP®130 Electric Water Pump Combo Kit to the EJ25 Subaru motor.

With the radiator up front and the engine in the rear it was important to ensure the cooling system was totally free of air. I ran the engine for approx. 20 minutes as I refilled and topped up the radiator. I allowed the engine to reach and indeed exceed the targeted/set temperature which is the factory setting of 85°C. I even elevated the front and then the rear of the vehicle on the scissor hoist.

The Davies Craig Pty Ltd EWP®130 Combo Kit and the Davies Craig 14” HP Thermatic® Fan operated within their parameters and kept the engine within the 8°C ‘window’ (80° to 88°) perfectly! I then road tested the vehicle travelling about 20klms. On return I allowed the engine to cool down then checked the coolant level. To my surprise I placed about 500ml of coolant into the radiator.

I road tested the vehicle again for a number of kilometres and on return and after the engine cooled down I checked the radiator yet again and still managed to place another 300ml of coolant in the radiator. I stress there was no coolant in the overflow bottle. In my view, the cooling system still had air in its system and it took these extraordinary efforts to expel all the air from the system.

Is there a moral to this story? Yes, we are all around cars, engines, EWP® installations and can take for granted some aspects of the engine cooling system. We discuss coolant levels etc. on a regular basis and from my personal experience it’s vitally important to check engine coolant levels regularly, regardless!

 WE PROBABLY TAKE IT FOR GRANTED NOW THAT Jaguar built its exotic V12 engine in larger numbers than any other manufacturer in automotive history and that it was created by some of the best engineering brains ever. I purchased a gorgeous 1989 XJ-S Convertible V12 in 2009 from Tony Dockerty in Melbourne. Tony was a true gentleman and known to many in Jaguar circles, but unfortunately he unexpectedly passed away late in 2013.

The XJ-S presented well, and it came with a full Jaguar service record and no modifications other than a non-genuine radiator and twin electric fans. After driving around Sydney during the Summer months, I noticed the coolant temperature would rise to about 110°C, so had it checked out at Cremorne Prestige where my good friend Greg advised that my after-after market cooling fans just weren’t up to the job. Greg maintains that the factory set-up works well provided it’s properly maintained. However, in my case, all original parts were now history so I needed to investigate an up-grade.

I set about researching the internet regarding cooling issues with the Jaguar V12 engine, and found plenty of material to read! This became the start of my journey towards a series of modifications to make my wonderful XJ-S more reliable, responsive and practical.
Any modification needed to enhance the car, and not destroy in any way the wonderful Jaguar refinement. The entire project started with the cooling system by sourcing a high performance single-pass aluminium radiator from Race Radiators in Melbourne.
The original system uses a dual-pass radiator design which I believe is not as efficient as a single pass one, so ‘while I was there’ I decided to remove the water pump with the intent of refurbishing it.

I then read an article about substituting the mechanical pump with an electric one identical to those used in many modern cars.
John Benson of Davies Craig in Melbourne has been supplying electric water pumps for years to a variety of vehicles, so I purchased the EWP 150 with the latest electronic controller. Fitting was a little challenging as I needed to make a new cover plate to replace the original mechanical pump and re-plumb it with new hoses. I mounted the EWP under the power steering pump connecting to the lower hose from the radiator, and then up to the input spigot that I fabricated on the original mechanical water pump cover.
I next fabricated a by-pass pipe between the thermostat housing. Input to the radiator is made via a new cross pipe with integrated filler neck. Davies Craig recommends removing the mechanical thermostats because the electronic controller is designed to manage the engine temperature by controlling the flow of coolant.

Because the Jaguar V12 engine needs to operate at 90°C for optimum performance, and the mechanical thermostats do a good job, I decided to retain them. With the combination of the Davies Craig EWP smart controller, and the mechanical thermostats, the engine temperature is now always at 90°C regardless of ambient temperature. Other features include fan run-on after switch off which helps reduce heat soak – which is very important and useful.
To manage the airflow through the radiator in slow traffic conditions, I installed a SPAL high performance twin 12” electric fan system which fits onto the radiator perfectly. The cooling up-grade makes for a very effective and reliable modification, and I now have no issues driving around Sydney on 30°C plus days. Never under estimate the importance of running the V12 at the correct temperature. If it gets too hot you will cook the engine, while too cold could result in over fuelling.

The next modification was aimed to improve the responsiveness and flexibility of the engine without destroying the original Jaguar refinement. I started by replacing the ECU with a re-mapped unit purchased from AJ6 Engineering in the UK. I also installed their larger throttle bodies and high torque manifolds, achieving better air flow to the cylinders. Cool air is directed to the intakes from the front of the radiator.
In order to install the new ducting, I replaced the bonnet from a six cylinder 3.6 XJ-S which has the higher bulge. It is the same type of bonnet fitted to the later cars with the factory installed 6.0 litre engine. I complimented the induction system with AJ6 Engineering’s high performance exhaust kit. Roger Bywater from AJ6 Engineering says: “Many people think that the exhaust system on a modern Jaguar is a little too quiet for a car with high performance pretention, and it is quite possible to obtain a reasonable increase in performance allied to a pleasing exhaust note without becoming an antisocial monster”. While this all generates more bhp, I wanted and achieved a more responsive engine with a hint of that enjoyable high performance sound.
I read a lot of articles about V12 engine under-bonnet fires, and really didn’t want to experience one! I therefore had a set of aluminium fuel rails fabricated by Ed Ward in Melbourne. It seems most of the Jaguar expertise resides in Melbourne!
These fuel rails are manufactured from extruded aluminium, and eliminate the horrible clip-on rubber hose design of the factory unit. I replaced the injectors with a set from the XJ-S 3.6 which has a similar flow rate. The end result is a much tidier engine valley.
The second stage of the modification was to install a Wolf Engine Management System to provide sequential ignition and fuel injection. This will involve replacing the ignition system with a distributorless ignition and more modern high flow injectors, a complex up-grade and will require considerable planning and patience. The nett result should deliver more simplified engine control. Ian Hissey has carried out this up-grade, and many other clever modifications to his well known XJ-S Cabriolet and has valuable information on his website www.ichi-intl.com.au.

All XJ-S V12s manufactured before 1992 had the GM T400 three speed auto transmission, but I really wanted an extra ratio to help with fuel economy and improved responsiveness. To that end I installed the GM T-700 transmission, with a conversion kit from John’s Cars in the USA. The job was relatively straight forward provided you follow John’s instructions to the letter!
I sourced a T-700 from a 1990 Holden Commodore, and had it rebuilt by a local transmission shop. I also installed a dedicated low-profile transmission cooler in front of the air-conditioner condenser. The original prop-shaft needed shortening, so John’s Cars supplied on exchange. In order to get the best out of the T-700, I changed the diff ratio from 2.88:1 to 2.54:1. The combined modification made a real difference to the car, and I don’t understand why Jaguar didn’t do it earlier.

The XJ-S steering and suspension has to be one of the best designs ever, coupled with the amazing independent rear suspension set up. Nothing here needed changing other than an up-grade to poly bushes and adjustable Monroe shock absorbers. However, when setting up the wheel alignment I opted for more positive caster due to the wider tyres and wheels I fitted. I installed 16 X 8 XJR-S Sport wheels which set the car apart from the standard model. Brakes are all stock and seem more than adequate for the job.
The electrics in the XJ-S after twenty years of use had become somewhat unreliable, so I set about replacing most of the wiring, particularly in and around the engine bay. I purchased a four headlamp kit from SNG Barrett in the UK which I modified for projector lenses sourced from a BMW 5-Series. I then installed HID lights which dramatically improved the overall lighting. Other electrical changes included wiring and relays for the cooling fans, horn, lights, air-conditioning and others.

The air-conditioning was up-graded to include a modern new lighter-weight compressor from SC Parts in the UK. I also replaced the condenser with a parallel flow unit, and the result is ice cold air-conditioning in the summer.

Internally, I had it re-trimmed and carpeted. The wood veneer was replaced with new Burr Walnut from Myrtle Productions in the UK who also manufactured a custom dash surround which is similar to the dash on the Facelift XJ-S. This dash surround uses the original speedometer and tachometer, but smaller gauges from the Series 3 XJ saloon. I changed all the gauge lights to LED which provide a more modern look at night. The result is a smart looking centre dash console which blends well with the rest of the interior. A new Alpine stereo system finishes it off with Bluetooth phone interface.

My XJ-S is now a real pleasure to drive, and I never think twice about making the long trip from the Southern Highlands to Sydney.

As an mid-engine Ferrari (from the 80’s) owner, I had just grown accustomed to the cabin temperature being affected by the power plant behind the cars occupants.  I made the switch to the Davies-Craig Electric Water pump kit last year (2015) and can state that there is a very noticeable difference. This is particularly evident when stationary in traffic where, historically, the cabin temperature would increase significantly and then slowly cool down when the car was moving again. This has made the ride comfort much better as the ambient temperature is better controlled.

Further to this the car reaches operating temperature quicker and cools down much faster – this is particularly beneficial for me as the garage leads to my study and so there is lot less heat coming into the study.

My only regret is that I didn’t make the switch much sooner. Based on my experience, I would thoroughly recommend that anyone considering to make the switch, to do so without hesitation.

The notion of the electric water pump was recommended (and eventually fitted) by David New from Dural Ultratune.

I'd like to wish everyone a great summer and give you all an update on our team's success in our 2014-2015 season. As many of you already know, for Formula SAE Electric programs, the season ends in Lincoln, Nebraska at the annual FSAE Electric competition. This summer marked the 2nd year that our team, Penn Electric Racing attended the competition - still a very short time compared to many of the programs that are now marking their 20th+ year at the competition.

Last year, with our team's first ever Formula SAE Electric vehicle - REV0, we earned a 7th place in the field of 20 electric vehicles. A placing we all we satisfied with given our standing as a first year car in the competition. We walked away having a number of aspects of the vehicle to improve before next season.

Throughout this past 2014-2015 season, we made the team-wide decision to design, manufacture, and test a brand new Formula SAE car from the ground up. We called it REV1 - our team's second vehicle.

From the start of the season back in the fall of 2014, one of our foremost goals was the expansion of our team. Growing from our team of 10 students in our 2013-2014 season, we ended the 2014-15 season with 30 students. This expanded group gave us the ability to take on slew of new challenges from our vehicles initial design to its final testing. We took our initial vehicle's design and evolved many of its most critical aspects - including its drivetrain, battery pack, chassis, and custom electronics.  

At this year's competition, the attention to detail on the safety systems and vehicle electronics allowed us to immediately separate ourselves from the field of 20 Formula SAE Electric vehicles by being the first electric team to pass both the Mechanical and Electrical tech inspections. We ultimately placed in 1st in 7 of the 8 dynamic and static events. Our dynamic performance on the track even placed us right amongst the times of some of the top placing gasoline Formula SAE teams. This earned us the 1st place overall award in the 2014-15 Formula SAE Electric Competition! 

First and foremost, we would all like you to join in on this immense satisfaction that we've felt since winning the competition. To every Formula SAE team, sponsors are often the separating factor between a successful and unsuccessful season. Your help this season helped to prove why that is true. We truly appreciate your support this year in helping to bring home our school's first ever Formula SAE victory. 

We hope that with your continued support next season, this will simply mark our team's first, with many more to come. Come the fall, myself or another member of the team will be reaching out to you personally to touch base again as we begin the new season. 

Enjoy the pictures attached below. I apologize in advance if I was unable to show every sponsor logo in the attached couple of pictures. We encourage all of our sponsors to display these pictures on their website. Also, please don’t hesitate to reach out to me to schedule a time to come in to see the car and speak with us. We’d be thrilled to host all of our sponsors.

Thanks again from everyone here at PER and we cannot wait to embark on next season with your support!

Best,

Tommy and the entire Penn Electric Racing team

THE PROBLEM
With the pickup used primarily to haul a big, heavy race-car trailer to and from the owner’s local racetrack, two parts of the 150km round trip from Auckland’s North Shore to Hampton Downs raceway always wreaked havoc on its 350ci small-block Chev’s cooling system: first, Auckland’s volatile traffic that often slows to a crawling bottleneck; and, second, the climb up the Bombay Hills after a hard day’s racing. Add situation A after situation B, and you were guaranteed a classic roadside situation with a pissed-off girlfriend sitting in the passenger seat giving the owner the ‘this piece of shit has to go’ look. It had got to the point at which enough was enough; either the cooling needed to be sorted, or the truck would be replaced with something new, boring, and reliable — yuck! Luckily, we were able to provide the owner with a simple solution before it was all too late.

XP Falcon runs a Windsor V8 and prior to running the EWP, was suffering from heat soak.

In the top hose I used what I make as a bottom hose radiator drain plug. So many aftermarket radiators do not have them and it is annoying to have to remove a hose. You cannot see the plug as it is underneath although we will never use the plug in this set up with the top hose.

The join came about as we could not find the correct top hose so the heater hose runs from the EWP back into the top hose into the fitting as that was the best place to fit it.

Here you can see the heater hose plumbed to the top of the block or just above the thermostat housing or beside the distributor. So in effect we bypass the thermostat leaving it in place to work as it should. With the engine cold we can flow water easily and even bleed the system of air.

The EWP is in the bottom right of the photo. You can see the heater hose to the EWP then back to the T join in the top hose.

EWP mounted up. EWP is just on a switch and next to the electric fan switch. Set up allows to turn on the pump and fan as required.
At highway speed the mechanical pump will be ok but the EWP can be turned on in traffic, slower speeds or at idle the same goes for the fan.

Have left the V8 at idle for some minutes to heat up after a test drive. This would in the past see the vehicle heat up with what you called heat soak.

With the EWP running and the vehicle at idle all appears to stay much cooler now.
Will find out more when the weather warms up but at this point in time this set up looks to me like it will work.

I thought I would send you a couple of notes on my installation of the Davies Craig electric water pump. The installation is not that difficult, but there are a few things you will need to do for it to be effective.

As Davies Craig suggests below, there is a simple approach and that is to remove the impeller from the mechanical water pump but replace the bearing and instal the EWP in the bottom radiator hose. That way you can use all the existing belts where they were. However, I have done the following to get the installation as tidy as possible;

1. Remove the mechanical water pump and pull apart. Have a 90 degree 38mm spigot TIG welded to the centre of the back plate. Weld up the other two holes. You will need to source some shorter bolts. Note the water pump bolts are all different sizes! I used a loctite gasket maker which worked well as the paper gaskets are terrible. The next challenge is to find a good location for the EWP.

2. Locate the EWP just behind and under the power steering pump. I sourced a coolant hose (38mm) from a Landcruiser HJ75 which bends in the right places. It will need to be cut to size so as to fit between the EWP outlet and the 90 degree input spigot on the blanking plate.

3. Next you will need to make a small piece of aluminium pipe that reduces from 44mm to 38mm with a 12mm T piece. Use a piece of the left-over 38mm Lndcruiser hose and connect between the input of the EWP and 38mm end of the short pipe.

 
4. Cut the original JGUAR bottom coolant hose so as to fit the bottom radiator outlet (44mm) and the short pipe. Connect the 12mm outlet to the header tank. This 12mm hose originally connected between the top of the bypass pipe to the header tank which essentially is the suction line.

 
5. I used some cable ties to keep the EWP close to the engine to ensure no movement towards the power steering belt.

 
6. By removing the water pump you loose a belt and idler pulley. I sourced a new belt that goes between the power steering pump, crank and A/C compressor. You will need to move the compressor slightly forward to line up with the power steering pulley. This can be done with nuts acting as spacers. I also fitted an new light weight compressor making this a little easier. Adjustment for this belt is at the power steering end.

 
7. The EWP has its own electronic controller so you don't need the thermostats. These can be removed along with the cross-over pipe.

 
8. I fitted a new aluminium radiator which was manufactured by Race Radiators in Melbourne. This is heavy duty and super efficient. I had it manufactured as a single pass radiator with two inputs on the top right hand side. I had a new aluminium cross pipe manufactured with filler and put in place of the old cross over pipe. I sourced some right angle hoses to connect to the left thermostat outlet and lower input to radiator. The right hand thermostat housing connects to the top outlet with existing top hose. You should consider fitting Tefba coolant filters as they protect the radiator.

9. I sourced 2 x 12" High Performance Fan & Shroud Assembly . This kit fits the radiator perfectly. Davies Craig also provide fan kits and you may wish to just replace the main belt driven unit with a 16" electric.

 
10. You will next need to install the Davies Craig thermo sender. I installed this in the right hand side thermostat housing which measures the coolant leaving the engine block before entering the radiator.

 
11. The electric fans can be controlled by the Davies Craig electronic controller. You will need to install relays and also arrange for control from the A/C compressor.I can send you some suggested wiring if you wish.

 
12. Be sure to instal the electronic control unit inside the car and NOT in the engine bay. I installed it in the glove box which works well.

A thermal clutch fan operates using silicon fluid as a viscous coupling medium. When the clutch is cool and disengaged, most of the silicon fluid is stored in the reservoir allowing your fan clutch to slip relative to your water pump shaft thereby spinning at a lower RPM than the water pump. This saves you money because the horsepower from your engine is not wasted driving a clutch fan when it's not needed. As your engine heats up, the thermal spring on the front of the clutch expands, which opens a valve allowing the silicon fluid to drive your clutch at an increased RPM. This provides more air flow through your radiator, preventing your car from overheating.

Since 2015 we have been gradually exiting the diminishing Fan Clutch market given most vehicles produced are now running Thermatic^® Electric Fans.

We have made converting a Fan Clutch set up to a Thermatic^® Electric Fan easier via our Fan Selection Tool (link below)

Simply search for you vehicle or enter the radiator size and the recommend Electric Fan needed will be shown.
