The Callaway Gen-Three Supercharger System will be equipped to all Callaway Sport Trucks. Callaway Cars has a long history of supercharging GM vehicles. This new supercharging system nearly eliminates “heat-soak” which is a common power-robbing issue with intercooled, boosted engines. According to Calloway, there was an increase of just 9ºF during individual test runs. Keep in mind: high temperature increases (at least 35ºF) are common with other intercooler designs.
The Callaway Gen-Three Supercharger System will increase output on the Calloway 6.2-liter V8 from 540 horsepower to 560 hp. Torque goes up from the current Callaway’s 522 lb-ft to 553 lb-ft. It’s a similar story for the smaller engine. All Calloway 5.3-liter V8s equipped with the Callaway Gen-Three Supercharger System (Chevrolet Silverados, Tahoes and Suburbans) power will increase from 460 hp to 480 hp and from 455 lb-ft to 477 lb-ft of torque.
According to Callaway, The SportTruck package price does not increase with the increased power; it remains at $17,395.
“Originally developed for the 2014 Callaway Corvette SC627, the third-generation, GenThree supercharger system is a completely new Callaway design. To increase airflow capability and reduce charge air temperature, Callaway engineers devised a new supercharger housing and integrated intake manifold. Intake manifold runner cross-section and length were tuned for a broad torque band while maintaining excellent peak horsepower. Eaton’s 2300cc TVS rotor pack was selected for its high adiabatic efficiency, OEM-certified quality, and service-proven reliability. Callaway’s new triple-element intercooler design provides significantly lower inlet charge air temperatures than possible with single and dual element designs. New carbon fiber manifold base covers provide a finished, premium quality appearance.” – – Callaway Cars
