i just bought the belt today the gates belt and wanted to know y its slipping i put the 9.5pulley on do i have to put shims on it or what but high rpms it slipps is there a real solution if anybody could help that would be great thanks

 

did you got the right size belt listed on NST website? my Gates belt keep slipping off because of bad idle pulley. I got the pulley replaced. Been fine since.

 

yeah just got the supercharger put on about 3 weeks ago and i got the belt today and pull it on at work and it squeal along with the pulley an were did u get the new idler pulley at it just seemed as soon as i hit 5000 rpms nothin but noises anything else

 

a small performance shop got it for me, he said he know someone from TRD. i think it was around 70 or 80 dollars.
How often it slipped off? At first my i notice my belt was not spinning at the center of the pulley. a week later, it got shredded.

You notice the my lower idle pulley is not align with the belt.

 

if you found out it is the pulley's fault, i have 2 idle pulley and nst pulley with belt for sale.

 

I had the same problem when I got the pulley and belt, I just went with a smaller belt. I don't remember the number, but you could probably go with a 1/2" smaller.
