I was reading the Dynotech report on the AMSNOW shootout Dyno's and they stated under the Zr900 dyno that all pulls were short quick ones. We all know the F7 likes heat! And doesn't make full power until warmed up. No wonder it Dynoed so low. The dyno report on AMSNOW from ArcticCat on Pre-production was a very long pull when the engine made 140+hp. They also stated that it was revving 8100rpm in the shootout runs which we know is way to high, and that on every run they had to back off the throttle when it pulled to the side. It would have been nice if someone competent had been riding the sled or done a long dyno, to show what it could actually do against the other sleds.
