aftermarket pulley

  1. 2003 - 2004 SVT Mustang Cobra
    I have an '04 Cobra motor with a Kenne Bell blower. Everything else is working fine, but I've been blowing idler pulleys (not the same one every time). They actually crack, start to split open, and then shred the belt off. I've never seen this before on other cars or applications. Anyone...
