[alfa] Mechanical vs electric fans - was single row timing chains



Whilst I'm more concerned with originality, I have wondered what the True hp difference between running a mechanical fan and the additional drag on the alternator from running an electric fan is. I'm guessing, on average, about 1 to 2 hp difference.

Yet, once again I have to agree with Brian Shorey in that whether one is sitting in the hot pits or a traffic jam idling away in, say Crawford, Texas, in the summer, you want full fan power at idle. Obviously once underway the person on the race track kills the fan.
