Belt Tensioner woes I have an LT1 in a 95 F-bird that eats belt tensioners.
This car is used in Road Racing and the wide RPM range kills
the spring on the OE belt tensioner.
I've seen mechanical tensioners for the LS engines and wondered if anyone
knew of a heavy duty piece for the LT's.

I use my entire rpm range 1000 times a day on my way to and from work. I don't see that as your reason for eating tensioners. Are you replacing the belt everytime? Is the tensioner fully seating on the acc. bracket? Check to see that there are no pulley's off of alignment.

This is an 8000 rpm engine and is hit a bit harder than street driving.
From what i'm seeing this was a problem for folks running the Firehawk series too. Pulley alignment measures spot on, but who knows.
As far as belt length, im about to think the belt is too long, and leting the
tensioner travel more than it should, and in turn causing the spring to break.
harmonics can be a mother, and mothers only half a word.
thanks for your help guys!!!!
looks like a good time to fabricate a mechanical adjuster.
