Davies Craig In The Real World

09/05/2019 12:00AM

The team recently sifted through the digital world to find the best pieces of video content that our customers have uploaded showcasing Davies Craig engine cooling products. We were extremely overwhelmed to find that dozens of videos had been developed showcasing our range, and how they’ve helped the builds of these YouTubers. So we’ve gathered our top 3 videos we’ve found and given some insight into what exactly went down…

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.
