Mighty 3.0L Whipple Supercharger Boosts GM HD Pickups to 500 HP

If you're hauling big loads or towing big trailers, you want as much power and torque as you can get out of your rig. If you're rocking one of GM's heavy-duty models with the 6.6-liter V8, Whipple has a new supercharger to help get you hustling down the highway.

As covered by Street Muscle Mag, Whipple's new supercharger is built for GM's 6.6-liter L8T engine seen in the 2500HD and 3500HD trucks built from 2020 to 2022. If your GMC Sierra HD or Chevy Silverado HD needs more grunt, this could be the way to go. While the L8T originally delivered 401 horsepower and 464 lb-ft of torque, Whipple's figures state its supercharger kit can bump that to 500 horsepower and up to 700 lb-ft of torque.
