[COBRA427]

After reading other forums regarding electric pumps, the concensus is, on the street, that's where they shine, they are great because even in stop and go traffic and lots of idling, the e-pump is circulating enough water to keep the motor cool. BUT, on a road course enviornment, with constant rpms 4000 and higher, the mechanical pump will pump more gallons per minute, around 100+gal/min vs e-pump at 55gal/min.
I have a new LS7 and I bought a Mezeire e-pump for it, but the car's not running yet, and since I plan to track it, I'm probably going to replace it with the stock pump or get an Evans, which is suppose to be about 20% more efficient than a stock one.
