The BIGGER brother of the HH range, yet still offering Stealth performance that fits under most standard hood profiles, this is possibly the best bolt-on performance improvement available for any mild modified LS1/2/6 variants including 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, including LS2/76/98 electronic throttle control.

Features
The Harrop/Eaton HH122 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 HH122 range of superchargers are based on the latest "5 1/2" Generation rotating groups.

The advantages of this new generation rotating group are;
- Greater efficiency enabling the rotating group to "capture" more air
- Less parasitic loss which takes less power to turn
- Create less heat which equates to greater power levels
- Larger intake creating less turbulence and allows more air into the rotor ports
- Quieter for that even more Stealth appearance
