One thing that can ruin a track weekend is a broken belt, resulting in your tensioner slamming down on your crank pulley, etc. For this very reason, I have been testing out various tensioner stops that will keep the tensioner from slamming down if the belt were to break. I am currently running the Detroit Tuned tensioner stop, but not sure how long it will stay on due to reports from the MINIs in the Grand Am series having the stop snap upon belt failure (not a good thing). ALTA’s latest tensioner stop looks to be a promising solution (see video below).
My concern with these devices is how bad they rattle or vibrate at wide open throttle. I have had a stop make so much noise in the past that I just had to take it off due to the harmonic resonance. I will see if we can get a unit from ALTA to test with and report back.
