Anyone that has run a 3.8rr upper pulley with a 6lbs lower n able to cure the belt slip on one of this blowers.. I have the rr tensioner n crank it so much that the belt snaps n shread in half.. If I don't do it I only see like 13 psi n car runs way to rich to even be able to get in it...any advice, help would be appreciated.. I have searched for answers but doesn't seem like many use the 3.4 crusher on higher boost app.. The motor is a 4.6 dohc.. I use gates hd belts.. Once cars gets to run for a bit I need to tighten it a lil more everytime cause belts seems to strech out..
