Why does the belt keep jumping off Has anyone gone through this? My belt keep slipping off at full throttle. I do have a converter but it never did this with just that. Ever since I went up with the rev limit and shift points. The belt comes off when I run her hard. Any suggestions?
Re: Why does the belt keep jumping off You will probably have to order a new tensioner pulley from Thunder Racing. This happened to me after my heads/cam install.
They sell the pulley that has a little higher lip on it to keep the belt from sliding off. There was no other way around it for me and not one problem since the pulley install.
I think it cost $50 - $65. Worth every penny!!

I installed the same "higher lip" pulley and my belt throwing troubles are history...

Re: Why does the belt keep jumping off I kept throwing my serpentine belt after I put together a combo that I buzzed up to 6600.
I got the ASP 'Larry' pulley that TR sells.
FWIW I first tried replacing the tensioner with a newer one and it did not cure the problem so don' bother.

Re: Why does the belt keep jumping off good info! I'll have to try that pulley out... i've thrown my belt twice (once giving it too much gas on startup (before I tuned it), and 2nd when I was messing on the expressway at 120)
Anyone have a link to it? I checked TRs page under pulleys but only tensioner thing I saw as 130 bux and didn't include pulley...
