I'm running an intercooled p600b procharger. I'm building a brand new forged 383 lt4 and I will be running the 2.65 pulley. My question is to anyone that is using this pulley to ge the most boost you can, do you have problems with the belt slipping b/c of the small pulley? If so, how did you fix this problem, and how much boost did you get with it? Thanks.

You may encounter some belt slip with the 2.65 pulley, but it should be ok. You have to remember, a P600B only has a 3.05:1 gear ratio compared to the P1SC/D1SC that has a 4.1:1 gear ratio. The pulleys for the P600B pulleys tend to be smaller than the P1SC/D1SC pulleys.
