Electric Water Pumps instead the Stock one

[Stefankerth]

Hello, i plan to run a EWP 110 in the lower Radiator Hose, instead the OEM one. The Pump will run with low speed when the Water is cold, and with high Speed if the water is hot.

Does anyone have this also, do you have change something else on the Coolingsystem. becouse i think the most on the water wil flow in the Front of the engine, and on the rear conector from the Head, i will get no Waterflow?

Sorry for my bad english:1zhelp:

best regards Stefan

my question to you is "why"?

you wont gain any power by doing so...

 

[eraezer]

so you are going to remove the t-stat? Or are you going to drill a hole in it so that the water can run thru when it's cold and the pump is pushing it?

What gains do you think you will see?

I (with the team) have use that pump in a formula student car and we used that instead of the stock one because we wanted to be able to have the water flowing in while in the pit with the engine off. And we needed the higher waterflow while driving (it was driven hard, Suzuki GSX-R600 (high comp. 13.5:1 instead of 12.5:1, varible intake manifold made with an 3d-printer, E85 as fuel, pneumatic gear change control and so on))

maybe for a race car being that it gets inspected and repaired every race. for a street car its pointless. the drag that the water pump puts on the motor is nothing. maybe 1/8 hp. then the reliability issue. belt driven water pumps have proven themselves on thousands of cars. electric ones haven't. there is a reason why no production car uses them. i wouldn't do it.

I run an EWP 110 in the lower rad hose as a booster to cover the stock "holes" in the cooling system.
