..."If we ran [an electric fan] off the alternator we would LOSE about... 1 horsepower total." Technically it would be 196 watts at 100% alternator efficiency. So running two walbros at 7A (idle pressure) would consume about 0.44 HP. Stock may be... 0.2 HP? (Anyone know the current draw of the stock pump at idle?) Talking differences in the fraction of a HP.
