Re: alternator
 
If your engines only makes 140 HP you could lose 2-3 hundredths, if you're making 500 HP, not so much.
Had a El Camino 350 2 bbd, turn the AC on it would drop from 60 to 55 mph, with the 454 it never made a difference.
Another example, a grownup can pick up a 50 lb bad of feed, a 4 year can't. = HP

And, cut it off in an EFI car, injectors open slower, leans the car. I played with that on the car I race now. Even after I tuned the WOT air/fuel ratio, I found nothing. Put two 16 volt batteries in it, picked it up a couples hundredths, no alternator & belt in the way. Starts quicker. Has to be hotter spark & starter speed.

Hi all,

Thanks. I didn't know I was old until you told me. LOL. My pops and brother were into the auto elec rebuilding business and I guess my brain retained some of their knowledge.
