OK Dan,
How much additional horsepower do you think is required to compensate
from the load placed on the alternator from running an electric fan? I
don't know if the 18 hp estimate is accurate; seems like that figure
would depend on engine RPM and vehicle speed among other variables, but
since a fan's real benefit is derived when the car is stationary, it
seems reasonable that a properly shrouded and sized electric fan in place
of the conventional fan would be more efficient at road speed.
I make these comments out of intuition, claiming no technical knowledge
whatsoever,
