The new Whipple supercharger upgrade is available for Chevy Silverado HD and GMC Sierra HD heavy-duty pickup trucks between the 2020 and 2022 model years, adding in an extra-large dose of torque under the hood. The blower also includes several customization options for enhanced under-hood visual appeal.
Whipple’s new supercharger for the GM 6.6L V8 L8T engine features a 3.0L twin-screw design, with a 112mm front feed inlet and cast-aluminum intake manifold. The charge air is kept nice and dense thanks to an oversized air-to-water intercooler with a bar-and-plate design and billet 6061 T6 tanks, plus super-high-density fins. The blower also includes a large dual-pass heat exchanger for consistently cool temps. A high-flow water system, billet idler plate, and adjustable idler system round out the highlights.
Properly installed and configured, the new Whipple supercharger boosts output to a claimed 700 pound-feet of torque. For reference, the GM 6.6L V8 L8T gasoline engine is rated from the factory at 401 horsepower at 5,200 rpm and 464 pound-feet of torque at 4,000 rpm. Impressively, the new Whipple blower is also 50-state legal (MY2020-2022 CARB EO #D-231-79), and is said to provide solid fuel economy when keeping your right foot out of boost.
The kit includes an HP Tuners RDT flash tool to reprogram the computer, as well as a VCM scanner for data logging and tire / axle adjustment. The new Whipple supercharger is shipped as standard in textured black, but is available in “any custom color option” if desired, with a selection of rendering images showing silver, red, green, blue, and yellow finishes as well.
Full pricing information for Whipple’s GM 6.6L V8 L8T gasoline engine supercharger is still forthcoming. Order options are expected this coming May.
