Water pumps

Electric waterpumps might save about 3 or 4 HP.But they use up some amps. & they will only pump a certain amount of gpm thru all of the rpm cycle,meaning they pump say 40 gpm at idle & 40 gpm at 5000 rpm.Where as the belt driven pump increases at higher rpm.I live just outside of San Antonio & you know how hot to gets I was wanting to go electric also but I'm not sure an electric could handle the cooling that would be needed.Maybe the highest gpm electric pump would work.All of those Chevy LT V8s I see at the pick&pull they all have electric pumps but I guess it depends on how much HP you have.

A Meziere pump that will cool a SBC on the street is around $360.
Take into consideration also, that the crank ultimately produces the power to run the water pump, whether it's running the pump directly or running the alternator to power the pump. Works well on a drag car where you can run the pump between rounds. Not cost effective on a street car in my opinion.
