Has any ever experienced a pulley going bad I have a 62 and the back plate is very shiny and not make the 19 to 20 it normally does ,I leaktest the car switched back to stock manis still only making about stock boost I tested the magnet at well I ran power to it and couldn't turn it I removed my pulley shims gap was
040 now it's about 020 with shim I replaced supercharger belts bolt belts pull the same boost about 14psi also I have been running DJs belt wrap kit for year no issues til this last 3 weeks

 

Anyone else that can't get a answer up here check your pulley gap had to end up replacing my 62mm with a 61mm

 

These after market pulleys are not made with decent springs, some are made with non spring material. When the gap decreases after being deflected just .040 initially then it is not a spring. The wrong material being used causes the springs to break and damage parts in the surrounding area unless the guard is used.
