Hey Will, what is belt wrap? I went down below the recommended 2.5 to a 2.4 pulley and am getting 12-14 PSI. I also have the 200 amp alternator which has a slightly smaller pulley. I was interested in getting a larger tensioner pulley but didnt know where to go. ZZP makes them for the series I?
Once my water pump blows up and i replace it, i will have replaced everything that is belt driven within the last 2 months.
(with exception to the idler/tensioner)
Harmonic Balancer- went bad
supercharger- went bad a year ago- new pulley on new SC a few months ago
and the killer that happened last week-
AC compressor. that cost 859.00!!! 600 just for the part. but DAMN ITS COLD NOW!
Ironically, these things didnt start going bad until i put the smaller SC pulley on.
