[QUOTE="mj8, post: 2917816, member: 20599"] IronTerp you are correct and before I called PA alternators I was planning on going with the 3.2. After talking with them they told me that the alternator is overspun from the factory so upping the alt pulley will extend the life of my stock alternator. The graph below is what is recommend to spin the alternator at not what the alternator is currently being spun at if that makes sense. You kind of have to rob Peter to pay Paul in way. If you get a real huge alt pulley you will slow it down...it being the alt..in the upper rpm range 6000-7000rpms but you will severely under-drive the alt on the idle side and will have problems charging and running accessories..3.5 seems to meet a little in the middle.
