Ok people here's my problem. I have a 99TA w/bolt ons which i recently had done. I went to 3.73s and also had the pcm programmed. Since that my car has started throwing belts. I've lost 2 already and at 30bucks a pop its getting costly. I've replaced idler and tensioner pulleys already. If you've had a similar problem give me an idea please! I just don't want to start replacing parts to find the problem.

 

at higher rpms? you might need an underdeive pulley with all the mods, steeper rear and higher rpms?

 

I would have almost be it was the tensioner pulley!?

I suggest using a straightedge on your pulleys and see if by chance one of them is mis-aligned?

Just grabbing at straws here.

 

check your ac...have the same problem on my truck and it has seperate ac belt that always brakes...it is not disengauging the clutch on the ac...its a switch somewhere

The most common cause for this is a loose pully. While running check if any of them or the excessories wobble, particularly the crank pully.

 

agreed, I've replaced a few on vettes

 

Thanks for all the tips people. Especially using a straight edge "good idea". I'll be working on the car this weekend and post what i come up with. Thanks again for the ideas!
