Loud Squeal after 5k RPMs and 5-6 PSI boost
 

Anyone know what could be causing this on the factory supercharger w/ a 9.5 pulley? It was puffing white smoke for a little while then it stopped now it makes a god aweful squealing/ buzzing noise and it wont boost over 5 pounds. Anyone know what it could be? I dont see any dust anywhere on my alternator or anything..... Its a goodyear gatorback belt that looks to be in perfect condition.

you are 100% having belt slippage problems...get a new belt

Oh ok, I have a gates but its the rite part number but it seems too small and doesnt fit rite. Will it hurt anything if i spray some of that belt dressing stuff on it until I can get it fixed tomorrow?

yea, it will be fine. Plus with the belt dressing, you should pick up another lb of boost or so due to the slippage.

dude didnt we just have this conversation in ur other thread bout it being slippage lol

Maybe, It was a different thing though!!!! I got my gates belt in now, the issue with the other post was that I had the Gauge tapped off the vac line from the BPV not the Vac line that goes into the throttle body.

So if the belt squeals it means its slipping?
