How long are the belts supposed to last or how often is it recommended that they be changed?
Th couple of cars I have seen run at the strip always seem to be changing or breaking belts after a couple of runs. Does the amount of boost determine belt life or is it the hard driving?
sometimes they last 20k miles....If you put the belt on properly and tensioned it properly, then you'll get a year(s) or more out of it. If it's not tentioned properly (belt slip or too tight) it will cut the life of the belt back dramatically.
