What will an electric water pump really free up power wise?

theoretically you'd probably see more power on a h/c setup, due to several things.
i would think since a h/c motor revs faster, less rotational drag would be compounded.
and second you're spinning a h/c motor higher than the factory 6200rpm...usually...which would further benefit from reduced paracitic loses.
considering the LT1s use to see 10-15rwhp with the electric pumps...and those were cam driven...i don't see why you wouldn't see similar on an LSx motor

Launching!
EWP from what I have been told will not last as long as a mechanical pump. Also they flow a constant rate of water all the time as to a mechanical increases with rpm. If you are doing drag racing where the engine works hard for short bursts its not a problem. If you are doing road racing it could lead to over heating issues. These are things I have been told. I personally have no experiance with them.

if i remember correctly, the mez EWP flows more coolant at a constant rate than a stock mechanical pump flows at something like 5000 or 6000rpms.
which means it would be better for road racing than mechanical.
don't recall where i saw the specs for coolant flow on the stock unit.
Angela ( 350 hrss on cz28) put one in her car about 2yrs ago. maybe shoot her an email and see how she likes it.

Let me know if you remember because I only remember that they put it on their blue TA (the one they ended up supercharging) and it gained 4 I believe. I think they did a MAF with it.
