In a snowmobile magazine here in Sweden the benched a F7 to only 129hp :wacko:

The sled is supposed to have 140 hp. The speed shop and magazine numbers I have seen here in the United States have been 137 hp to 140 hp.

every dyno is different

What elevation was it dynoed at. The 140 HP is at the factory on their dyno. A higher elevation will reduce the HP output, less air.

D&D Racing dyno testing reported.....bone stock F7....at 137.6hp @ 7600 rpm, 95.9 ft lbs of torque.

With the addition of V Force 3 reeds, +3 degree timing key, ported cylinders, head mods, and 92 octane fuel achieved.....152.8hp @ 7800-8000 rpms, 102 ft lbs of torque


is 137.6 close enough to 140???

I heard they have the hood open. It´s a long way for the air to travel.
