not sure about the way optimistik went about saying it, but he has a point
a 3 mile race at an average of 100 mph only takes a minute and 40 seconds....if your engine cooks after 2 minutes of WOT then it has issues
one thing that isn't taken into considering in snowmobiling (I find) is aerodynamics. I'd say whichever is the more aerodynamic sled would win. And other things such as rotating mass and ski resistance become huge factors at 100mph +
