most guys are running the 1111 or 1115 belts. I am one of the few who is running the 080 belt without any issues. Granted I'm a flatlander running a 755 fuse, but I do have the dynoport setup on my sled, which should get me near the stock 900 hp numbers. I have the slp push and torque arms on, and am running the 719 team helix.
