Gary Arment on his 830 with the winning pull at Old Settler's Day in Smith Center Kansas. He had the 45 degree tread on his tires and they always seem to bite the track better and he pulled it out the end. It was a very impressive pull.
Max RPM is 1,400, but top 300 RPM is useless, max power is from 1,125 - 900 then it starts to taper off slowly, but she will keep plugging along till 500-600 rpm range which is idle speed.
