Moroso water pump drive kits

My experience was that the electric motor with the belt that turns the W/P is barely adequate for drag race use.

I used the bigger pulley on the motor, and you don’t want to use any restrictors.
It also helps if you eliminate any thermostat bypass in the system(all the coolant flowing through the radiator all the time).

I used mine on a 485hp 383.
In normal air temps, the temp would just keep going up until you shut the engine off.

Prior to running the electric pump on that combo, I was using a regular fan belt off the crank for cooling.
No thermal runaway with that system, but I wanted to be able to cool the motor down between rounds....... which I was able to do with the moroso drive kit.

It was also worth a little ET, not driving the W/P & fan off the crank, along will being able to run cooler water temps each pass.
