Clutch vs. Electric Fan

Another thing to think about is putting a minnie swith on the throttle that will turn the alternator off at WOT, saves about 2-3 hp and it'll run off the battery while you go down the track. To add save even more power, you can get an electric water pump drive, it's just a little electric motor that runs the water pump with a belt.

I don't have much experience with electric fans so I'm going to ask this...If you are running an electric fan only by a switch, I assume that you would keep an eye on the temp gauge and turn it on when needed, correct? It seems to me that if the electric fan was running constantly-- it would not last very long.

They make temp probes that you stick in the fins of the radiator and you can wire it in after the switch on the dash. On the street, the fan comes on only when the radiator gets hot enough and you don't have to worry as long as the switch is on. Go to the track, flip the switch off, boom.
