Default EWP or Stock water pump.

So everything’s finally moving forward on my 408 project, well at least to the point I’m beginning to doubt the last few details of my setup 😂😂


the car currently has a meizure ewp on it, and I can’t remember if that’s a “it’ll be fine” or a “don’t ******* do it” on big boost iron block setups and I figure I’d i need to get a GM pump on it I should do it now before everything is in the ******* car.

Opinions? Experiences?

AC/Heat will be deleted, I have a dewits cut radiator. Combo is an Iron 408 GenIV LS3 setup with a YSI-B overspun.

In my experience the meizure ewp sucked ***. I was also running and iron block turbo setup. The car wouldn't stay cool. I switched back to a stock pump and all my cooling problems were fixed.

Talking to people who have used EWP with big power, I am told the pump does not keep up while making several pulls and the coolant temp will keep going up. They cruise for a minute and the temps come back down after just a couple minutes. The factory pump moves more volume and keeps up way better. I really wanted a EWP because of potential belt issues. Break a belt and the water pump is no longer working. With an electric I could limp home and not have to worry about over heating. I am still on a stock pump atm.

OEM pumps work...and last almost indefinitely.

I can see few reasons to ever consider electric.

Yeah all these comments are basically what I remember reading. EWP officially sitting on the workbench and for sale!! Lol


is there a mechanical upgrade over stock in the aftermarket or should I grab an LSwhatever version and not worry? I figure if I have to buy one might as well spend the money on the best available.

You could go with an Evans water pump. Be ready to pay though.

IMHO The only real use for EWP is a dedicated drag car for quicker warm up and cool down between rounds. Have tried running them on the street with poor results.
