Exhaust System Design for a Four Cylinder Engine 2002-01-3316
The 2002 Lawrence Technological University Formula SAE team set out to develop a tuned exhaust system for a restricted Honda CBR 600 F4i engine. The exhaust system was targeted for maximizing low rpm torque while maintaining a broad flat torque curve without a significant loss of high rpm horsepower. In order to do this, considerable attention had to be given to the exhaust primary tracts, collector and silencer designs. To test theory, two equal length, fully adjustable headers were manufactured and tested on an engine dynamometer. Experimentally, the optimal exhaust design to meet our vehicles needs was determined.
