CSC rear drive

CSC rear drive is a project to modify the drive system of a Ski-Doo Snowmobile currently used by the University of Idaho Clean Snowmobile Project. The goal of the project is to relocate the drive wheels from the front of the snowmobile track to the back of the snowmobile track. It is believed that this configuration will increase efficiency and power output of the snowmobile; a portion of this project will be dedicated to testing the veracity of this theory.

Background
The SAE Clean Snowmobile Challenge is an "...engineering design competition for college and university student members that challenge engineering students to reengineer an existing snowmobile to reduce emissions and noise." The University of Idaho has had a CSC team participating in the challenge since 2001. An enterprising snowmobile drag-racer by the name of Shawn Watling designed a rear drive system for snowmobiles that is claimed to deliver a 72 percent increase in fuel economy. Watling's design requires substantial modification a snowmobile's chassis. Hoping to incorporate this substantial improvement in efficency into the University of Idaho CSC snowmobile, Team Powder Train has been charged with the design of a rear drive system that does not require any modification of the chassis, as any modification would violate the CSC competition rules.

Team Powder Train
Team Powder Train, who endeavor to design a working snowmobile rear drive, is composed of University of Idaho senior Mechanical Engineering students Zoltan Kiss, Josh Dalton, and Aaron Patterson.

Design Goals

 * System instillation
 * bolt-in design
 * OEM apperance
 * no chassis modification
 * Weight
 * no greater than 25% weight increase
 * Fuel economy
 * reduce the fuel consumed by the engine by increasing efficiency in the drive train
 * Efficency
 * increase percentage of engine power tranlated into movement
 * improve the effectiveness of the track system
 * Noise
 * do not increase noise
 * reduce noise if possible

Prior design
A prior team of senior University of Idaho ME students designed a snowmobile rear drive for the CSC team but the design failed to meet all the project goals.
