Need help with electric fan wiring

[donsrods]

Has anyone here run an electric water pump on the street.They work great on my drag car with an electric fan. I would like to have a dash mounted switchable unit that powers a relay turning on the water pump and powering the thermal switch to turn on the fan as needed. Also couldn't you use a rheostat to control the speed of the fan since it is a DC motor.

A few months ago I ran into a guy with a T bucket and was surprised to see an electric water pump on it, I always thought they were drag race only. He said it works great and frees up some HP.

Thanks for this thread, guys. Sorting this out has been on my list for a while.

Now about those pesky studs in the fan hub.
