(August 14, 2013) In another first for Callaway, the specialist manufacturer has just developed a new version of the service-proven Eaton TVS supercharger for the 2014 Silverado/Sierra 5.3-liter. The Callaway system includes a new supercharger manifold and other hardware required for the new Chevrolet L83 "Eco-Tec" engine.

Callaway engineers also developed calibration for the new-for-'14 GM electronic powertrain management system. Significantly different for 2014, the new electronics control Direct Injection, continuously Variable Valve Timing, Active Fuel Management and other engine functions.

While the new powertrain management system provided new challenges for Callaway's development staff, its additional control authority also provided improved refinement and integration of positive manifold pressure, through all the transient conditions of "normal" drive cycles. The Callaway Silverado's performance and drivability are nothing less than spectacular. The development project is now in the final stages of in-vehicle testing and validation; final horsepower and torque rating will be released very soon.

Developing the new Silverado/Sierra engine management calibration is especially important because the 2014 Corvette uses much of the same powertrain management architecture and controls. Lessons learned in developing the Silverado/Sierra system have been extrapolated to the new Corvette platform. Consequently, Callaway enjoys a significant head start in developing the supercharged 2014 Callaway Corvette and Silverado/Sierra 6.2L.

Development is also underway for Silverado/Sierra optional equipment, such as suspension components for improved ride and handling, wheel and tire packages, brake systems and interior upgrades.

Authorized Callaway Dealers are ready to take orders for the new Callaway Silverado and Sierra 5.3L Crew Cab now, with Extended Cab and Standard Cab models following soon. Callaway will introduce the supercharged 6.2L-equipped 2014 Callaway Silverado, Callaway Sierra and Callaway Corvette later this year. Tahoe and Suburban for 2014, and their GMC Yukon, Yukon XL and Cadillac Escalade counterparts, are carried over from 2013 with only minor changes.

No horsepower ratings were provided for the supercharged pickups.
