The latest generation in the Harrop supercharger 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 standard through to 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.The Harrop HTV (Harrop Twin Vortices) supercharger system is a Roots-type supercharger manufactured utilising the latest Eaton TVS (Twin Vortices Series) rotating assembly. Built for a variety of engine configurations and high performance applications that delivers more power and better fuel economy for uncompromising high performance driving. The Harrop HTV supercharger's design features patented four-lobe rotors with high-flow inlet and outlet ports that greatly enhance thermal efficiency, delivering higher volumetric capacity, and enable higher operating speeds. The HTV supercharger is capable of running with a high efficiency across a very wide operating range.The four-lobe rotors feature 160-degree twists. The higher helix angle of the rotors coupled with a redesigned inlet and outlet ports, improves the HTV's air-handling characteristics without increasing the overall size of the unit.The new Harrop HTV1900 sets a new standard of supercharger performance and reaffirms Harrop and Eaton's leadership in the performance automotive market.

Features
The Harrop/Eaton HTV1900 Series is a significant improvement over all previous Eaton HH based products on the market. This new Harrop/Eaton HTV range of superchargers are based on the latest Eaton TVS 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.
