There’s no doubt that the new Gen 5 Small block engines found in the Corvette Stingray and the Chevrolet Silverado are the most technologically advanced engines that Chevrolet has ever built. But concerns about some of the new fuel savers like direct injection, variable valve timing and the active fuel management means that tuners will have the step up their game to unlock the hidden power the LT1 is capable of providing.

Although many tuners are already promoting their packages for LT1 upgrades, only Callaway has demonstrated the ability to actually supercharge an engine in the “Eco-Tec” family by installing an Eaton TVS Supercharger on a 2014 5.3L Silverado.

Callaway is showing these photos of the Eaton TVS supercharger on the L83-powered Silverado with the data collection instrumentation still attached. The Callaway system includes a new supercharger manifold and other hardware required for the new L83 “Eco-Tec” engine. Callaway says their engineers have also developed calibration for the new 2014 GM electronic powertrain management system. These new electronics control Direct Injection, continuously Variable Valve Timing, Active Fuel Management and other engine functions.

As the 2014 Corvette Stingray uses much of the same powertrain architecture and controls, the lessons learned on the Silverado will give Callaway a jump on developing a supercharger system for the LT1 found on Corvette Stingrays and the 6.2L Silverado/Sierra platforms.

Callaway has yet to show the final numbers the Eaton Supercharged 5.3L Silverado is producing but according to Callaway’s Chris Chessnoe, they like the direction the program is heading.

And if you’re wondering about reliability, take the example of Callaway’s Supercharged C6 Corvette Grand Sport demonstrator car which has now logged over 166,000 miles with no mechanical issues.

The Callaway Silverado and Sierra packages start at $17,395. Other upgrades from Callaway include suspension components, brake, wheel and tire packages and interior upgrades for the new trucks.
