Hummer H3 Alpha Supercharger System

Product Information

For 2008-09 Hummer H3 Alpha 5.3L SUV’s

System Features

House of Boost is pleased to release our custom supercharger systems for 2008-09 Hummer H3 Alpha with the 5.3LL engine platform. This system is the perfect performance addition for stock or slightly modified vehicles.

With 6-7 psi of boost flowing through 3" mandrel bent tubing, the systems produce 45-50% power gains on stock motors running pump gas. Even with a conservative tune, these systems deliver cool charge air temperatures and high horsepower gains with the industry-leading ProCharger supercharger head unit. “Quiet” head unit models are also now available.  

Featuring the quickest and easiest installation in the industry, these kits require only a few basic hand tools.  With no need for complex wiring or “punching” of the oil pan, this system can be installed in a matter of 2-3 hours, and can be returned to stock just as easily. From the billet aluminum mounting brackets to the ultra clean plumbing, these kits are in a class of their own with OEM-quality fit and finish.

House of Boost supercharger Tuner Systems are currently shipping, with 100% complete systems to follow suit shortly. Tuner Systems exclude injectors, and tuning. Supercharger upgrades available up to ProCharger F-1C. Alternate supercharger brand systems also available upon request as well as injectors.
