Hi I have finally find my problem in a tuning shop.... Its in my Supercharge... MY Main Shaft Is broken in 2....

.... A shaft of 7/8inch...its crazy... One week before My JRSC Broke... i have change MY tensioner for the OEM AUto tensioner... LIke some guys told me here.... Did you think my shaft broke because i have too much tention with the OEM tensioner... Or Its a manufacture default???(I have sandblast my SC pulley too)
(SOrry im from canada)
Thanks
