1. 2006 SAE Clean Snowmobile Challenge Team Members: Steve Battaglia, Brian Belmont, Dan Bughbee, Kevin Gastle Mike Ide, Kelly McRory, Eric Peckham, Dan Sweeney, Greg Tilley

2. 2006 Competition Goals Create a clean and reliable naturally aspirated four stroke snowmobile. Mate an M-10 suspension to an Edge chassis to create the best ride and drive. Lower emissions and quite exhaust noise.

3. Team History Two first place finishes (2000, 2005) Lowest Emissions (2004) Quietest snowmobile (2005) Best Fuel Efficiency (2005) Best Overall Performance (2005)

4. Purpose of Competition Create a more environmentally friendly snowmobile –Reduce noise pollution –Lower emissions –Increase fuel economy

5. Design Engine Mount Fuel Injection Exhaust System Sound Reduction Instrumentation Suspension Aesthetics

6. Engine Mount Design Cradle Design. Utilizes chassis mounting points. Utilizes Engine mounting points. Create least amount of Vibration.

7. Fuel Injection We used a closed loop Bosch Motronic System. TPS and RPM controlled system Programmed for lean combustion.

8. Questions

9. Exhaust System Stock manifold cut down and adapted for shorter system Flex coupler to allow for chassis movement Lubrizol 3-Way catalytic converter Honda Silverwing muffler (same as last year) Exhaust exits in stock location on right sided in front of chain case

10. Sound Reduction Used sound reducing material from American Acoustical –PDP –VE –Hushcloth Melamine –Millenium Metal

11. Instrumentation EGT Avenger III Data Acquisition Unit –Tachometer, Exhaust Temperature on both cylinders and after catalytic converter, Coolant Temperature, Oil Temperature

12. Suspension M-10 rear suspension –Over 13 in. of travel –Has done very well in the public market for touring sleds. –Lightweight Stock Edge Front suspension –10 in of travel –Stiffer Springs for heavier four stroke

13. Aesthetics Keep the sled appealing to the general public –Kept the stock look of the hood since the edge body is widely accepted by the public. –The entire sled is set up like a stock Edge Classic with the M-10
