Does anyone use an electric water pump on a street car? If so, do they cool better than a mechanical?

Electric pumps don't pump as much coolant as a stock pump at high rpms.

Good for cooling between rounds though.

Meziere has a series of pumps out now that claim 55 gallons/minute! The old standard was around 37.

Now, 55 gallons/minute is damn near a gallon per second! I know this is with zero load, and when it has to push coolant through an engine/radiator, it will actually be much less... But what kind of amperage do these things draw! The ad in Jegs said it came with a 40amp relay. The ad also said the units had enough capacity for truck pullers and off road use.

Pretty soon, cars are going to be needing two alternators! (I guess all the new electric gizmos is why auto manufacturers are going to a 42V 'or there bouts' system soon.)

My old Morose (uses a Ford heater blower motor with a pulley and belt to spin the stock pump) works fine for me. I simply installed the larger pulley, and it cools just fine... even on the street. However, it might not be up to the task this coming year with the new 'filled' block. Hopefully my new Derale #16926 (best electric for a 65-66) fan will make a significant difference over the old generic 16" unit.

Good Luck!
