Baffled About Supercharger Belt Sizes!!

  1. I have a 6.87 inch Crank pulley with a 2.75 inch Supercharger pulley. Vortech says the distance between the two should be 53.6 inches, my car measures 52 inches... Any suggestions as to why mine is way shorter...? Vortech states that I should use a 54 inch belt, I put on a 53.5 inch belt and it's still too long and I'm getting alot of belt slip. Does anyone know where to find a 52.75 inch belt??
  2. When I adjust the tensioner, the belt touches. Nothing on set-up has changed, original set-up was built 20+ years ago. Put in new motor, used all original parts, and that is why I am baffled.
  3. There are 2 sets of holes on the blower that will adjust the tensioner try moving that around.... the holes are for the bolts that lock the vortech tensioner in place.
