Callaway to Supercharge 2014 Chevrolet Silverado and GMC Sierra, Output Estimated at 450 and 540 Horsepower

By Trevor Dorchies | July 03, 2013
What's more American than a big pick-up truck? How about a big pick-up truck with a supercharger and the capability to squeeze out between 450 to 540 horsepower? Callaway, the company who brought you this, is doing just that, and will be offering you the ability to supercharge both the 2014 Chevrolet Silverado and GMC Sierra. The engine design company is already chipping away at the latest version of a supercharger for the GM's latest full-size pick-up trucks and should have it ready to go once the trucks begin arriving in showrooms later this year. As stated above, Callaway's supercharger will be good for an estimated 450 horsepower with the 5.3-liter V-8 engine and 540 horsepower with the 6.2-liter V-8. Callaway says if you're going to purchase this set-up, to "expect premium performance, quality and value consistent with other Callaway car and truck packages." Both supercharged engines are expected to be ready to go once the 2014 Chevrolet Silverado and GMC Sierra go on sale and will be able to pull every cab and bed configuration. To squeeze out more power, besides using the supercharger, Callaway will also employ direct injection and variable valve timing. Callaway's engineers have also been given more control of engine operating limitations and because of that, they've been able to tinker with the supercharger's manifold pressure, and comply better with emissions rules in all 50 states. Other tweaks to the 2014 Chevrolet Silverado and GMC Sierra supercharged versions include wheel, tire, interior, and other body changes. These same changes will be made available on the Callaway Supercharged SportTruck, which launches later this year.
