Peter's (thumprr) tensioner is the ***** best IMO. I honestly would not worry about going to an 8 rib if I was under 450 rwhp, but that's just me. I'd just get the tensioner and a good gates belt.

If you're seeing a lot of belt dust, then chances are it's more of a rubbing/alignment issue than slipping. Check your belt to see if you are getting any fraying anywhere and then track the source. In some cases, one or 2 of Peter's billet 76mm smooth idlers are the easy fix as sometimes the belt likes to rub or hang on the edges of the stock idlers. The #7 pulley is also sometimes culprit (it's the ribbed one to the left of the power steering pulley).

You can go to gates website and enter your zip code and find local retailers for the belt...

heres a link to the 8 rib

either tensioner is fine w/ me as long as it doesnt slip. anybody got any experience w/ either one, i here the thumprrr one is great, havent heard about the BGG one.

Check your idler pullies, one of mine went bad and was causing my car to through belts. (pic included)

I just got my Thumprr tensioner today. I will be trying it out shortly. I purchased two billet idler pullies. They should be here tomorrow.

My 100mm idler that comes with the whipple was making a sqeaking noise at low rpms. It eventually went away by itself.
