The "street" mezeire ewp is heavier than a stock ls1 pump by about 2 lbs. I didnt notice a change in power or normal cooling temps from installing mine. The ewp flows more at idle, but the mechanical flows more at mid/high rpm. The biggest benefit of an ewp is having the choice to run it and the fans when the car is not running to quickly cool the motor.

so no real benefit for a 10-0-% street car?

100% street car I would say its a waste of time unless you like extra buttons. I believe the rated hours on the electric motors are relatively low compared to failure rates of mechanical pumps too.

If you have an underdrive pulley, I recommend you get a high output alternator or an overdrive alt pulley for it, otherwise you might have issues sitting at hot idle.
