[QUOTE="IronTerp, post: 2830561, member: 12702"] The 4 lb lower will get you 16.9 psi of boost when in conjunction with a 2.80 upper according to Mosoniac's chart. I've been running a 4 lb lower now for 7,000 miles with factory alternator pulley, (knock on wood!!!). This issue can go either way......stay with the factory 2.60" alt pulley and you'll "overspin" the alternator by 13.16% or go with the 3.20" alt pulley and you "underspin" the alternator by 8.06%. Thus, the decision should probably rest with how you drive.......if you're more conservative, lot of city driving w/ lower rpms, keep the stock alt pulley IMO. If you like consistently cruising on the highways at 90 mph and hit the track for 80 runs a year, you may want to witch out to a 3.20"....... [/QUOTE]
