Meziere has just released their new bolt-on electric water pump for the LS1. This is a direct replacement to the factory pump and will show you a 10-12hp gain. Colors available are black (most popular), neutral, red, blue, purple and polished. Our introductory price is $499.99. This should be going up to around $530. in the next few weeks.

I can see how it showed gains on an LT-1, but what is the reasoning behind the LS-1 since it is not cam driven?

 

well, maybe its gear driven by something on the motor, so going electric may of freed up some power..

I will not do this as my LT1 mezz did not flow enough for me.. But being here in Houston we can sustain higher RPMs for much longer durations of time.

 

I was pretty sure the pump was belt driven on LS-1/

 

Yes it is.

 

It's still driven by the engine. No difference.
