To gain more power out of the first car I drag raced I made a electric water pump set up. The car was a 81 Horizon and I bought an electric water pump called a "Water Guppy" that was used to circulate water in bass fishing boats. I had the water pump off of my car (due to bad leaks) and found that the thermostat housing had two bolts that lined up with two where the pump was. I simply bolted on an extra thermostat housing in place of the pump and then put the electric one in line with some longer radiator hose. I ran the pump with a simple on off switch in the car and in hot weather it worked like a dream. I never checked for gas mileage. A trick that a lot of drag racers use is to cut off every other fin inside the water pump. They have less drag, more power, more miles per gallon, and adequate cooling.
