[QUOTE="Willie, post: 2656851, member: 14133"] [b]First...the use of the larger alternator pulley with the larger lower will maintain close to factory rpm specs for the speed of the alternator. At all engine rpm's from idle on up. The lower speeds it up and the larger alt pulley brings it back down to where the factory wants it.
