Ok so a friend of my dads brought his race car (427 s/c hemi) over to our house and told us that the superchargers belt was "warping" or being stretched out of shape so we looked at it and sure enough it looks like the belt is a few inches longer than the length between the pullys. So dad went and got a new one and we put it on and the guy started the car and reved the engin a few times and then we start to hear this "flapping" noise, when we look at the belt again it looks like the one before. so we check to make sure its not snaging on any thing and that the pullys arent wobling and every thing checks out ok. so dad then tell the guy to leave the car with us and well try something else later and he calls around to find a belt with higher tension rating. Well the belt came in to day and we put it in and it did the same thing as the other two, dad says he has never seen any thing like this befor. The belts arent breaking or tearing only stretching out of shape. any help would be appreciated.

do all of the pulleys rotate freely? if any of them are dragging, like an alternator with bad bearings, or a seizing water pump, this could theoretically happen.
