‌Since 1987, Whipple Superchargers™ have been the pioneers and leaders of twin-screw supercharging. Whipple was the first to bring positive displacement technology to fuel injected, emissions legal GM applications. With over 34 years of GM twin-screw supercharging experience, Whipple’s team is now the first to bring you the most powerful, 50-state legal, intercooled twin-screw SC system for your GM LT 6.6L direct injected engine (L8T) 2500/3500 Heavy Duty truck. Featuring the record breaking, race dominating Gen5 twin screw supercharger, 112mm front feed inlet, cast-aluminum intake manifold and complete intercooler system. What does all this mean? How about 700 ft-lb of neck whipping, tire shredding torque! 

The all-new system features Whipple’s massive oversized air-to-water bar-and-plate intercooler with billet 6061-T6 tanks and super high density fins for unmatched cooling capacity. Combine the efficient intercooler design with the record breaking, championship winning, industry leading 5th generation 3.0L Whipple twin-screw supercharger. The unique intercooled bypass system offers better acceleration and less than 1hp of consumption during cruising for excellent fuel economy.

The system also includes a massive dual pass heat exchanger for incredible recovery time and consistent cool temps whether your daily driving, towing or racing through the mountain side. The new system also features an aluminum high flow intake manifold, high flow water system, billet idler plate and adjustable idler system. While others claim, Whipple Superchargers simply deliver more power per pound of boost than any other supercharger on the market today and continue to lead the industry with incredible innovative products. Kits come with HP Tuners RDT flash tool, VCM scanner for data logging and tire/axle adjustment. 

Each system is available in standard textured black finish or nearly any custom color option, allowing you to customize the engine compartment for that show finish.
