Hey Bos, what type of idler setup do you have? My thinking is perhaps if you had the steel idler and increased belt speed due to the pully setup as well as increased surface friction by the 8 rib configuration, that you are getting increased heat on the idler. There have been a couple of steel idler pullies that have melted bearings. I know when my idler pully came lose it shreaded a belt in no time. Perhaps either the idler bearings have gone bad or the idler itself is loose, or both. Just an idea.

Isn't the steel idler supposed to be the "better" upgrade....I will have Speed check all of that too to make sure that isn't the culprit..
Thanks for the imput....

I would definatly check the idler. I have change the bearings in mine twice due to heat failure. I have the steel idler.

the picture of the pulley isn't that clear, is it similar to the stock ATI set up or isit totally different?
scott, what diameter is your crank pulley?

How about having some custom pulleys made that have taller side flanges on them? That should keep the belt from walking off.
That is like like increasing your fuel pressure to 90psi to lower your duty cycles to 90% from 100% if that makes sense.
You wouldn't be fixing the problem you would just be trying to "get around it." Then you run into issues of tearing up belts.
It HAS to be an alignment issue. Maybe the pulleys ARE perfectly aligned but maybe you need to offset them, ever try that? I know on my old procharger setup i had to offset them a bit to keep the belt on (8 rib)

off set them as in having the pullies on parallel planes or have them pointing at eachother with an angle? ( -- __ or \ /)

I know I'm not experienced with the blower cars, but...
Have you thought of doing a slow motion video of the car on the dyno, and watching it to see the belt flex, or perhaps exactly where the belt initially comes off the pulleys? You could do a shot from each side, one on top and one from the front?
Nothing can replace an actual hard data stream...
Just a thought.

I mean the obvious first place to check is alignment. But you said you and speed inc. checked it thoroughly and the alignment was straight. So I'm thinking what else it might be. Check it out and let us know what you find.

I was doing some reading on CZ28.com, came upon this site that makes custom tensioners for the ATI kits, anyone running one of these?
