This is the best bolt-on performance improvement available for any L76/98 including LS2/LS3. 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.

The 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, the HTV Supercharger delivers more power and better fuel economy for uncompromising high performance driving. The design features patented 160 degree twist 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.

With the Intercooler cores mounted internally within the manifold and a large front mounted radiator, the high efficiency Water to Air intercooler setup is guaranteed to stabilise air intake temperatures and provide consistent power delivery.
The standard HTV1900 kit will deliver 8psi which is recommended for factory stock engines. High boost pulleys are available for modified and rebuilt engines with forged internals.
