HUMMER H1 SUPER 77 UPGRADED TURBO

HUMMER H1 SUPER 77 UPGRADED TURBO

The SUPER-77 features a high-tech billet compressor wheel of proprietary design, which is combined with compressor housing modifications to create a dramatic improvement in compressor-side performance. These compressor side upgrades are combined with changes in the turbine drive wheel. The net result is a superior turbocharger performance with reduced transitional response time, lower required exhaust drive pressure and greater efficiency in production of manifold pressure. The SUPER-77 is a direct, bolt on replacement for the factory turbo used on the H1 and includes a Mechanical Wastegate Controller and is preset provide 16 psi of boost at full throttle.
