Harrop Commodore/GTO Supercharger Kit for 5.7 and 6 litre V8
Stealth HH112 and Stealth HH122
Offering Stealth performance that fits under most standard hood profiles, this is possibly the best bolt-on performance improvement available for LS1/2/6 variants including VZ L76/98. The package delivers exhilarating yet totally affordable supercharger performance, representing exceptional value and reliability. The increase in usable torque is outstanding, while maintaining (and consistently improving) fuel economy. Kits now available to suit all models from VTII cable, right through to the current VZ electronic, and including LS2 electronic throttle control.
All Harrop supercharger packages share the following passion;
- Designed, manufactured and supported by an 100% Australian company using only Harrop and Eaton components,
- Harrop Engineering is the only Eaton-trained, authorised and certified supercharger company in the Southern Hemisphere,
- Full ADR/EPA approval pending for our latest range of HH112 kits,
- Available in shot-peened or polished finish.
Features
The Harrop/Eaton HH112 Series is a significant improvement over all previous Eaton 112 based products on the market which were based on the Eaton 5th Generation M-series of rotating groups. This new Harrop/Eaton HH112 range of superchargers are based on the latest "5 1/2" Generation rotating groups.
The advantages of this new generation rotating group are;
- Greater volumetric efficiency which enables the rotating group to "capture" more air per revolution,
- Less parasitic loss which takes less power to turn,
- Create less heat which equates to greater power levels,
- Incorporate a larger intake area which creates less turbulence and allows more air into the rotor ports,
- Quieter for that even more Stealth appearance.
