after having my p1-s/c upgraded I went with a 3.10 pulley and made 14 lbs. of boost @ 6000rpm...now I want to lower the max. rpms to 5100 to keep everything in one piece ... all the math done I have gone with a 2.65 pulley and had a couple extra idlers made to keep the wrap on the pulley tight...thinking it should bring me about 22 lbs. @ 5100 and will not be over spinning the supercharger...here's pics.
this is the 14# set up
this is the lower idler I had before
this is the upper idler...a little rubbing I found...too close
new pulley difference
new set up
this is behind the bracket...2 lower idlers redirecting belt to power steering
much better wrap of the belt.. had to go with a inch shorter belt
this is the 14# set up
