Callaway Cars – one company that takes cool cars and trucks and makes them even cooler – received its first 2014 Chevrolet Silverado and GMC Sierra trucks this past week. Engineers are working hard to produce Callaway’s latest Supercharged SportTruck, which will launch later this year. Coinciding with the supercharger development are the wheel, tire, suspension, interior and body upgrades to create an unbeatable truck package. The technologically advanced EcoTec3 engines, with direct injection and variable valve timing, allow for greater control of engine operating parameters and additional tools for improved compatibility with supercharging’s positive manifold pressure. The 5.3L is expected to produce more than 450hp, while the 6.2L is expected to produce more than 540hp. Every GM-built cab and bed combination are slated to be available from Callaway. Because the 2014 Tahoe, Suburban, Yukon, Denali and Escalade remain mostly unchanged for 2014, Callaway Supercharged versions are now available!
Lingenfelter Performance Engineering took delivery of a 5.3L crew cab 4WD 2014 Silverado in June. Because the 2014 CK trucks are the first to get the direct injection Gen V GM V8, it will be a suitable test platform. Lingenfelter has been performing data gathering tests through running the Silverado on gasoline and on E85, with stronger performance coming from the E85 (65% alcohol content). On gasoline, their 4WD short bed crew cab (3.07 rear differential) performed a 7.5 second 0-60mph and 15.94 second 90.75mph quarter mile with peak power of 302 horsepower and 332 lb.-ft. of torque. Two runs on E85 returned duplicable results: 6.96 second 0-60mph and 15.51 second 93.4mph quarter mile with peak power of 321 horsepower and 355 lb.-ft. of torque. A test run in August at Muncie Dragway, now equipped with a Magnuson TVS 1900 supercharger, resulted in an elapsed time of 13.89 seconds at 100.07 mph on pump 93 octane gasoline. Dyno numbers resulted in 397 horsepower and 425 lb.-ft. of torque. Prototype camshafts are on hand, and cylinder head port flow development work and CNC programs for the cylinder heads will be completed soon. Development is also under way for supercharger and turbocharger packages.
The race is on for performance tuners to perfect their versions of 2014 GM trucks.
