Davies Craig Electric Water Pump

[mambastu]

Has anyone fitted a Davies Craig electric water pump to their car at all and if so how have you found it compared to the original mechanical pump ?

We have one fitted to one of the race cars (not a Skyline), so far it has worked perfectly. Gives quick warm up and no cavitation at high rpm, plus we can run it after engine shut off to cool it down. Via the Motec we get to choose the engine running temperature, much easier and more accurate than using thermostats with various opening temperatures.

So far not a bad thing for a race car, I wouldn't be doing it on a road car though, to much hassle and no real advantage using it in that environment.

particularly if, as I understand it, the skylines pumps don't cavitate at street revs ie up to ~ 8000

There was going to be an Autospeed article about it but after they presented the finding of their tests to Davies Craig they were threatened with legal action and therefore disn't publish the article.

Would have been interesting to read!

Thanks for the replies fellas.

Received an e-mail back from Davies Craig today and looks like the EWP 80 is too small for an RB and the EWP 110, which would be fine, can't be used with the current controller. There will be a new controller out in March/April apparently.

On a VT commodore, it caused lots of problems and Davies Craig themselves had the car for 2 weeks and couldn't sort it out.

This was back when I owned a VP and was thinking of putting one on.

As far as street performance goes, there theoretically should be a very small gain, but I doubt you'd notice it.
