I actually did this on a Camaro race car n fact t is stll in place as I am rebuilding the car, I had it on a dyno (rolling road) and you could defnitely see a drop of about 4bhp when I kicked in the alternator much to the disbelive of the dyno operator. Interesting point here though as a mate of mine who used to run in a short circuit Sierra formula where the rules forbade alternators (???) went to enormous lengths to secretly fir one including a pully off the main drive shaft as he reconed the battery drain during the race effected the power. He may well have been right (he won the series) and if I had let the battery run down a bit on the dyno in my test may well have seen a loss of power.
