Fully wound out on the lake I have seen 115 to 120+ on the speedo but since most speedos are off I would quess about 110 + actual but mind you this is on a cold day little wind and a long stretch at Lake of the woods Northwest Angle Snake lake trail.This sled also had a 1 1/4 track with 96 studs installed mild clutching but it was not pulling the right rpm as it was below 7700 rpm and I forgot to bring the lake running weights with so it could have been better with a little less weight in the clutch.
