Reason I'm asking is I have seen test done where it takes 15-30hp to spin a manual cooling fan (depending on type). So everyone says go electric. But with the added demand of the electric fans and most likely larger alternator, how much hp is really freed up??

Non-racing application but going from a 160 amp alternator to a 320 amp Mechman alternator costs me like 2 miles per gallon in my Tahoe. It definitely has a significant draw.
