Thread: Cooling !

No gain. Takes more juice to run it than you save on turning a water pump mechanically. And the alternator will have to make the juice to run it, which just moves the mechanical function from the water pump to the alternator. And most of them, unless you spend upwards of $350, will not move enough water to run them on the street.

Great for a race car though, if used with an electric fan. You can cool the motor between rounds without running the motor to turn the mechanical water pump and engine-driven fan.

There will be those who disagree with me, but it's hard to beat a properly-sized radiator (I'd be thinkin' 500+ square inches), full shroud, thermostatically-controlled fan clutch and 18-inch, 7-blade OEM steel fan (I'd be thinkin' minimum 2 3/4" pitch), driven off the crank with a Flow-Kooler or equivalent water pump.
