Default Belt Thrown

For two years I have had this set up, While doing a cam swap I added a new underdrive Harmonic balancer from Texas Speed, of course they send the new belts to go with the set-up. I did notice that with old OEM serp belt that the Tensioner pulley could back travel quite a bit to put tension on the old belt set-up. After the UD Harmonic Balancer and new belt, I could barely get the new belt around the pulley and the tensioner barely traveled back at all. So the Tension Pulley is almost fully opened (for lack of a better term). after about a year I noticed a sqeak from that area could not pin point where from exactly. Then about a month ago the belt either slipped off during a rev or it broke during a a rev. All i remember was reving the car up before it happened. First question, is the Tension pulley designed to operate that far out, and second How do you measure how many pounds is on the belt itself because i know they have limits too. Has anyone else ran into this? Thanks

Try using a shorter belt. They might have sent you the wrong belt.

A shorter belt will not fit. the Tensioner pulley is maxed out and I can barely fit the one I got on it now.

I thought ASP were the ones people were having trouble with because the shoulder were not deep enough.

Is that a 25%?
You need a longer belt. Do you know how to look at your maximum minimum marks on your tensioner?

I have a 25% powerbond and I run a 76" gatorback belt with it.

That pulley calls for the same belt size mine uses. I think you got a stock size belt because a stock size belt will max out on my pulley too. Look at the belt, get a part # off of it to see what you actually got.
If you cant see a # then just order a CONTINENTAL 4060760 Poly-V belt Effective Length 76"
Its the same as a gatorback and took all the squeaks away. That's what I'm using.
