Callaway to give 2014 Chevrolet Silverado and GMC Sierra a boost

Wed, 21 Aug 2013

Callaway has just announced the debut of supercharged versions of the 2014 Chevrolet Silverado and GMC Sierra pickup trucks. This news comes only weeks after Callaway made known their intentions to fit market a version of the Silverado with an Eaton TVS supercharger.

The Connecticut-based tuner has developed a new supercharger manifold and some other hardware for the new Chevrolet L83 Ecotec engine, which is expected to produce around 455 hp (though these are preliminary figures). The stock version of the Silverado uses a 5.3-liter V8 engine, making 355 hp.

Callaway also reworked the engine calibration for its version of the supercharged Silverado and Sierra trucks for the all-new 2014 GM electronic powertrain management system. The system required a few tweaks to make the supercharger work in concert with the electronics-controlling Variable Valve Timing, Active Fuel Management and direct-injection systems in the trucks.

Callaway hints that their tuned version of the 2014 Chevrolet Corvette is not far off, pointing out that the engine-management calibration in the Silverado uses the same powertrain-management architecture found in the all-new Corvette.

Exact power figures haven't been announced yet, though authorized Callaway dealers are ready to take orders for the Silverado and Sierra 5.3-liter Crew Cab now, with Extended Cab and Standard Cab models to follow soon. Packages for the first two models will start at $17,395 each. Plus, of course, the cost of the new truck -- of which well-appointed versions can sticker for more than $50,000.
