Disconnect your alternator and see how much you gain at the strip in MPH. I guarantee you a 140 amp alternator takes quite a bit more than 5 hp.

Disconnecting the alternator is way different then just running a higher amp. You no longer have the parasitic loss due to the belt tension and alternator bearings, etc.. Even if you were running a 1amp alternator, you'd still have those losses. Keep the belt on, pull the alternator wire harness, and let us know the difference. I bet going from a mechanical fan to electric would more than make up for the extra alt load.
