Snowmobiling blues...

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.
I remember my friend had a formula Z I'm sure it was early 90s. I'm pretty sure it had something to do with the limiter strap? Something about keeping the skis on the ground? Well anyways this one had it didn't have it it was like a Wheely King?! When you nail that thing it wanted to stand up!
