Callaway working on supercharged versions of 2014 Chevrolet Silverado, GMC Sierra

Article by Anita Panait, on July 4, 2013

After getting their hands on the first 2014 Chevrolet Silverado and GMC Sierra trucks last week, engineers at Callaway have commenced their work on developing their latest Supercharged versions of 2014 GM SportTrucks. Callaway will start product development, testing and validation of the 2014 Silverado and Sierra in the next few months.

Supercharged 5.3L and 6.2L versions of every GM pickup are expected to be available later this year. Using its proven supercharging techniques, Callaway expects to top 450 horsepower for the 5.3L versions and exceed 540 horsepower for the 6.2L version.

The new 5.3L and 6.2L EcoTec3 engine will integrate a number of technological advances like direct injection and variable valve timing, allowing engineers at Callaway to get greater control of engine operating parameters. The features will serve as tools for improving compatibility with supercharging’s positive manifold pressure for providing a better way for complying with emission rules and extended durability.

Callaway is also developing upgrades for the pickups' wheel, tire, suspension, interior and body. The upgrades will be available just in time with Callaway Supercharged SportTruck launches later in 2013. Callaway Supercharged versions of 2014 Tahoe, Suburban, Yukon, Denali and Escalade are already up for grabs, and they largely unmodified for 2014.

Callaway is also currently developing its own upgrades GM’s latest truck and SUV products, including a version of their Honker air intake and DD exhaust systems. These components will be made available as stand-alone products, ready to be installed either by the buyer or by Authorized Callaway Retailer on stock GM trucks and SUVs.
