Ski-Doo 850 Turbo Clutch Kit testing Zac 22 850 Turbo

Zac in Montana @ 9000 feet. 2900 engagement speed. Doing validation testing for our iBackshift Ski-Doo 850 Turbo clutch kit for 165hp. Engage speed is 2900. Stock clutching the engage is 4k and sled moves at 4300. With kit, at 4300 rpms you're doing 14mph. Lower engine speed at part throttle in the trees. Where stock clutching pulls hard to say 48mph track speed, but around 43~44mph, you can feel that typical vibration in your feet with stock helix. Ok you get 8000 rpms but there is more conversion to be had. The kit pulls another 3~4mph track speed at 6500 feet in Revelstoke with 220# rider with gear. Engine braking holds to 12~13mph before declutching. Can gear to a 20 top and still pulls HARD. Engine brake holds to 10`11mph. Typical iBackshift clutch kit backshift, super strong, LISTEN TO THE WHIRL OF THE TRACK. Your sled will just CHEW. Thanks, Joey
