Background Information Turbocharger system must be light
weight, reliable, serviceable, and efficient
Appropriate size will be determined based on intake restrictor, spool time, and chassis space
Heat management and cooling aspects are essential
Turbo is favorable over supercharger due to vibration issues and torque curve
Added weight must be justified through reduced lap times, power increase, and increased fuel efficiency
