I can't answer why some belts last and some don't. I'm not a car mechanic
so I don't know all of the various ways to measure run out on pulleys or
even really know how to adjust them if they weren't lined up (other than
flipping them over). In supercharger applications, the belt does run faster
than it would regularly. I would imagine that makes a perfect fit of the
serp. belt pretty critical. I can say though, that the stock waterpump
pulley does not have edges to it to line the belt up, it just sits wherever
it wants to. Like I said in an earlier post, I've learned a lot -- that's
what makes it fun for me. Being able to blow away EVERY Mustang and ricer
that's ever tried is kinda nice too. I'd love to come up a gainst one of
those new Ford Gt's..
