If you own a Chevy Silverado HD or GMC Sierra HD equipped with the 6.6L V8 L8T gasoline engine and you simply need more power, then ProCharger has a solution. The company is now offering a new supercharger package that adds substantial gains in both horsepower and torque, providing the boost needed to perform when towing or charging up a mountain pass. The setup will run on premium pump gas, and will install as a simple bolt-on package.
Properly installed, ProCharger claims that the new supercharger kit will add 6 psi of boost pressure, upping output to more than 600 horsepower and 700 pound-feet of torque. Compare that to the 401 horsepower at 5200 rpm and 464 pound-feet of torque produced by the Chevy Silverado HD and GMC Sierra HD in stock guise, and this supercharger should make quite the difference when you put your foot down.
The kit includes a dedicated six-rib belt supercharger system, as well as a large front-mounted air-to-air intercooler to make the boost nice and cold. The system was designed to run on premium pump fuel (91 to 93 octane), while PCM tuning is included.
Installation is framed as a relatively simple bolt-on process, which ProCharger says can be completed on a free day on the weekend with basic hand tools. PCM tuning entails sending the unit in to ProCharger, where it’ll get re-flashed and over-nighted back to the owner for installation.
“When ProCharger engineers designed this system, they wanted to make it as DIY friendly as possible,” ProCharger states on its website. “Meaning, there is no cutting, bending, or tweaking of any sort being done to the truck. In fact, the entire system can be removed if you are ever trading in the truck or selling it.”
ProCharger also states that installers are available across the U.S. if you prefer to have a pro tackle the job. ProCharger did not list a price for its Chevy Silverado HD / GMC Sierra HD supercharger kit, but does encourage interested customers to contact the company directly for more information.
