I don't know everything but he did say pipes/clutch/heads/gears the standard stuff. My SXR has about 150hp if I was to guess. My sled is as fast as it is because of the clutching and my driveline tweaks. That same day I ran two different helix combos. Both were 48/43 but one is a Bender and one is a Hauck. The Hauck runs awesome in the trails but top end is 101 on the gun with that Hauck. The Bender can't pull more than 8100 RPM in the trail but runs 110 on the ice. It's a strange combo. Doug
