I am hoping someone here might have had a similar issue. My car is eating belts without seeing boost under normal driving. Shifting around 3k. I have bought a laser alignment tool and all pulleys are spot on. Fabbed up a tensioner to sit on the belt where I thought the belt may have been tossing from the alternator to the PS however that did still not help. Otherwise it's 8 rib conversion, Innovators west 18 % OD pulley, Thump racing tensioner 76mm, Vortech 2.65 pulley. Feel free to jump in with suggestions and I can add pictures if necessary. Hoping to fix it and drive to Myrtle Beach in a couple weeks for Mustang week.
