2.5" or 2.6" with over-sized tensioner pulley and GM Stage 2 belt?

The reason I ask is because I have 2.5" w/OS tensioner pulley and GMS2 belt and I have broke the shock (on tensioner bracket) twice. Should I go back to the stock belt and oversized tensioner? Or GMS2 belt and stock tensioner. Or should I say F^*k-it and try both of them (GMS2 belt and OS tensioner Pulley) again?

I'm going to try to use just the oversized tensioner pulley and stock belt with 2.5"

Bump

 

I would say go w/ the ZZP Tensioner and leave the stock belt, a buddy of mine is running that same setup w/ a 2.6" and has no slip problems! Good Luck, just my 2 cents

 

i run the zzp tensioner and a gm stg 2 belt with my 2.7 and i have had no problems so i would say do that

 

im running the stock tensioner with stage 2 belt and its cool

 

I am running a 2.5" pulley the gates oversized tensioner and the stock belt.I have no belt slip.but up here at 3500ft I only make aprox 17 psi boost.
Did you get the misfire sorted out?

 

I think so....I'll update everyone later this week. I want to take it easy for a couple of days first.
