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 that delivers more power and better fuel economy for uncompromising high performance driving. The 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.
