I hear you on that, but as a daily driver it would seem the water pump is not the most efficient mod to do performance-wise.....or am I missing something?

I too had written off the electric water pump. But after hearing Hwg and Chevy, im changing my mind. My limited track experience shows a HUGE difference between a cold engine (Cool) and a hot one. Guess It goes back on the list. Still, after headers and gears, which go in tomorrow. Thanks guys.

To the contrary, I said the output level was more important to me than the HP gain. I think the effecient factor outways the performance factor. How could doubling your output not be better for your engine with daily driving?

I have the Meziere water pump. I haven't installed it yet. I read somewhere that it produces 11HP at the wheels. But, like anything else, it depends on the setup you already have.

But a thought just occured to me. How does it know when to turn on? Is it always on? That would be a bad thing as far as battery life when you're parked listening to the radio. I'd prefer to have it wired so it only comes on when the engine is running.

I would assume it doesn't come on when your key is in accessory mode.
