Well as most of u know my Balt is supercharged by zzp kit. This uses a 3.1 pulley and comes with a bracket with a pulley on it to finish. the belt circuit. Now I have the smallest pulley they make. I want to run a 2.8 so I need a solution. What is needed to run this pulley? How do I use the 1 rib cut stage 2 belt. Do i need to swap pulleys?

 

bump, do i just get a lsj tensioner and idler pulley and cut a rib off so i can a smaller pulley? only haven't 12lb of boost isn't cutting it, lol. Want around 15-17. Already have #60 ready to go, just need a retune.
