im thinking about converting to an electric fan for the hp gain mostly.

which fan do you guys recomment getting ?

will my alt be strong enuff for an electric fan ?

will i need a relay if so which one and where do i get it ?

I tried the electric fan route. Used two pancakes in front of A.C. condenser. The ratty old fan and fan clutch turned out to be much better. Just my experience.
Use one Radio Shack auto relay for each fan. The relay will take current right from the battery. The fans draw from 10 to 20 amps each. Hope you have the 85 Amp alternator, which was standard with air.
