I really don't feel that an electric water pump is ever a good idea on a street car.
As far as electric fansÂ…. IMHO they are the way to go. Running a thermostatically controlled switch is the best for street applications but at the track a simple on/off switch is fine. Another cool set up i have seen is a throttle switch that cuts fan power at wide open throttle.
During a pass you shouldn't need or be running the fans.
