Ya I think you guys are right,8-9lbs is 92mm pulley,that's the size I have I believe.

Bigger pulley means more boost correct me if iam wrong?wonder if they are carrying bigger pulleys.The vq engine can handle 11lbs on stock bottom end as long as you monitor properly.

Other way around. Smaller pulley means more boost.

After talking with gamma about the pulley sizes and I was told the 92mm pulley is 9-10 lbs at sea level ......so depending on altitude would affect the boost pressure
