Abstract	implemented high-performance four-cycle internal combustion engines into an existing snowmobile chassis. The team’s complications in past years did not rise from using a 4-stroke engine in a snowmobile. The problems arose from the simple fact that all the previous engines were originally motorcycle engines which did not have dimensions or configurations consistent with that of a snowmobile engine. This led to difficulties in packaging, drivetrain modifications, and additional weight. For 2007, the team has decided to take a completely different approach in building a snowmobile for the competition. Instead of spending significant engineering effort on engineering the cohesion between engine and chassis the team decided to start with a stock snowmobile engine and chassis. Our OEM snowmobile choice was the Polaris FST Classic. This selection allowed more time to be spent engineering improvements in emissions and noise beyond the OEM implementation and less time on packaging and drivetrain modifications. The above decision combined with a team-designed exhaust and intake system, along side custom fuel mapping have made significant reductions in emissions and noise possible. The net result is a snowmobile that is not only environmentally friendly, but also a pleasure to ride.
