LS7 throwing belts
 

Our LS7 conversion using all Corvette LS7 accessory drive parts except A/C is throwing belts. With our belt tensioner in the middle of the range it tosses the belt when you flog on it. The first belt lasted a while but we have tossed two very quickly now. Any suggestions?

Thanks!

Make a little metal "L" shaped bracket that rests slightly above the belt. Doesn't matter where, just where ever it fits and the problem will be solved.

Old drag racer tirck. ;)

ive never had any experience with this situation, but im under the impression that katech makes a tensioner that will help.

Since you're using all LS7 accessories and drive, you may be interested to know that GM made a change to the alternator that allows it to free-spin on decel - a one way clutch on the hub. The alternator has a lot of mass and when the throttle is snapped shut at 7k rpm, some people were throwing belts. There's some talk about this on CorvetteForum.

I had the same problems with my main drive belt on f body acc. Katech tensioner installed and not one problem since
