And yes, what DSX said. Alternator output is varied as loading conditions change BUT the output of the alternator has little to do with vehicle speed (MPH) and more to do with engine speed (RPMs). SAs never cease to amaze me...
So do you suppose coming out of a Texas-turnaround in 2nd gear at 5K rpm would maybe supercharge my battery?
If your sport doesn't put blood, dirt or grease under your fingernails,
then it's just a game.
