I have a built motor with a Whipple, currently running a 6rib setup and shredding belts @10lbs. I ran a string around all my ribbed pulleys to check alignment and everything seems to be aligned correctly, and when I drive normally, there is no noticeable wear on the belt...only when i get into boost and shift quickly at high rpms.
My guess it is because I still have the stock tensioner. So I need to upgrade, but not sure which one to go with. In the future I will be converting to an 8rib setup and will have a race tune on high boost, so I need a tensioner that is going to hold up to 800rwhp and work with the 8rib also once i get there.
I hear a lot about the Thump Tensioner, but it says it is only good up to 500.
Any feedback from folks with experience in this department would be appreciated. Thanks much.
