Yeah, I raced a few of the big CC sleds across the lakes at those events. Once we hit around 60 mph they begin to pull away. Mine was 670 Formula Z (two stroke of course). I beat some 700's, but most 800's and up I just ran out of motor compared to them once the clutches changed gearing for the big end....LOL. I never lost a race to the same or smaller CC though..... Some of them guys had the 1000 cc yamaha's with turbos. 140+ in the 1000 ft. Probably low 9's/high 8's at the 1/4 mile strip.
