    Belt Issue

    My power band is super high, peak HP is at about 6700. Problem... Whenever the motor is kept at such high RPMs I have a belt slipping issue. The belt will start to make noise, I pop the hood, and find the belt half way off the pulley.

    Will an adjustable tensioner solve the problem?

    I had a similar problem. At high RPM, the engine would throw the belt. Mostly once the belt had a few miles on it. But, I found the tensioner would wobble or go irradic and allow the belt to come off. (I filmed it under the hood.) I think there was a link on youtube of a similar one.

    Anyway, I bought Katech Engineering LS1 tensioner and it looks good now. Haven't had the belt problem again since.

    I had that problem with my (non) high revving 6.0. Put it to about 6400 RPM and it slipped two ribs once. I bought the Katech Solid tensioner. Haven't had one problem since. Great piece.
