Yes, it is cheap horsepower, just dropping the fan off could give you that
increase,
but have you considered the extra power required by the alternator to
generate
the electricity to power the electric fan? And that conversion from
mechanical
to electrical energy and then back again isn't exactly lossless either... So
you
go from a system using mechanical energy to blow air around, to one that
uses
mechanical energy to create electrical energy which is then converted back
into
mechanical energy to blow air around. I really can't see how any extra
usable
horsepower could be created by using an electric fan unless the electric fan
is several orders of magnitude more efficient than the old mechanical fan.
However, I am, as usual, happy to be set straight... And I'm not against
electric
fans per se, it's just I can't see how you could possibly gain any benefit
in terms
of horsepower - I can see the benefits to cooling ability as the fan is
closer to the
radiator, and probably blows more air through it, but....
