Date: Spring 2012

Requirements:
The entire powertrain system weigh no more than 80lbs. to provide a weight advantage. The intake system must be resonance tuned to match the speed of sound in air at elevated temperatures. The exhaust system must limit sound to 110 dbA, a FSAE competition. An extremely accurate boost control system must be utilized in order to protect the engine from excessive load. Finally, the lubrication, cooling system, and drivetrain must handle the increased load from a forced induction setup.

Problem:
For the last 10 years, Longhorn Racing has used a high output, four-cylinder Honda F4i motorcycle engine . To reduce weight, this year's team has chosen to use a much smaller single cylinder engine from a Yamaha 450 all-terrain vehicle (ATV). However, this choice entails a significant power loss that could potentially decrease the longitudinal acceleration capabilities of the car. To ensure that this is not a problem, the aim of this project is to create a powertrain system that produces a comparable power to weight ratio as the 2011 entry.

Solution:
After a thorough competitive analysis, the team concluded that a turbocharger forced induction system provides the best results for competition. The team selected a suitable turbo and designed, built, and installed the necessary auxiliary components in time for the 2012 competition. The car is expected to deliver slightly more power than the previous year's vehicle, with a significant decrease in overall weight.
