Callaway SC520 Package Equipment

GenThree Supercharger

GenThree™ TVS R2650 Supercharger System
with TripleCooled™ Intercooling

Callaway’s patented GenThree™ TVS 2650 supercharger provides 520 horsepower and 490 lb-ft of torque, 165 hp and 107 lb-ft more than stock. Fuel mileage is practically unchanged from stock as the supercharger’s internal bypass mechanism diverts the inlet air flow path during idle, low-load cruising, and deceleration, allowing the supercharger rotors to spin freely. Plus, Callaway’s patented TripleCooled™ intercooler system employs three high-flow heat exchanger elements to reduce inlet air temperature, eliminating power loss typically encountered with supercharged vehicles during aggressive driving.
