[Fot] Trying to mount an electric fan on a high density radiator

to gain the hp.


I've always wondered how changing to an electric fan causes a gain in
horsepower. Or, to put it another way, decreases the loss of power used to
drive the fan.

Lets' say, for simplicity, that the electric fan and the belt-driven fan move
the same amount of air. If the fans are equally efficient (maybe this is where
I'm off base), then the same amount of power is used to drive them. The only
thing that has changed is that the power comes from your alternator instead of
the crankshaft. But the alternator robs power from the crankshaft, so what do
you gain? Also you have introduced a middleman into the sytem, which increases
losses.

What am I missing?
