Electric Water Pump Benefits

[Gareth87]

Hi,

I have been doing a bit of research on EWPs and can find plenty of info but not so much real world testing. Does anyone here run an EWP?

Was there a notable difference in cooling efficiency and does anyone have a dyno reading as to how much gain can be made. (hp gain is secondary, just curious to see what the real difference is)

Cheers in advance.

i honestly dont think there would be a big if anything HP gain but i dont know? as far as am EWP you can taper it to help keep your car at a constant temp at the track etc i dont think its worth it for a street car?

From a mate's experience in his old Merc with an electric fan combo.

- Great for heavy traffic in summer.

- Engine slightly more responsive.

- Heater doesn't seem to work as effective - Takes ages for the heater to warm up.

- Less heat soak, pump continues running for a few minutes after engine is turned off.

- Controller had some gremlins after working flawless for a year:

- pump did not turn on once - nearly cooked his engine.

- pump never shut off when he turned off the engine - ended up with a flat battery.

Great for controlling Temp, they are used on alot of big gun cars these days. As stated above technology does come with a price, and often a problem!

I'd go for one myself. able to slow and speed up water flow depending on temp and working electric fans from the same controller (like a Davies Craig) could allow fast warm up and constant temperature control.

When I get some money up I will buy and test this, but for the moment will stick with the old crank driven pump, only because it still works
