Since 1985, Eaton has been producing Supercharger rotating groups to boost performance from automotive engines and Harrop has been an integral technical partner on this journey after being announced as a licensed master distributor for Eaton in 2007. Harrop is the only company outside the US that is licensed to utilise Eaton technology to manufacture Positive Displacement Superchargers and Traction Control Products for low volume applications. The resulting Harrop series of TVS Superchargers showcases unique design characteristics that sees them as world leading in performance and durability.
The TVS™ supercharger’s patented design features twin four-lobe rotors with 160-degree twist (410, 900, 1320, 1900 and 2300 sizes) and 170-degree twist in the new 2650. The high-flow inlet and outlet ports have been redesigned to greatly enhance thermal efficiency, deliver higher volumetric capacity and enable higher operating speeds of up to 24,000rpm. The TVS™ supercharger is capable of running with a high thermal efficiency (up to 76 percent) across a wider operating range, whilst having improved noise and vibration characteristics to eliminate additional noise-reduction treatments, complexity and system cost. Additionally, the Harrop supercharger incorporates a bypass system to reduce air handling losses when boost is not required, resulting in better fuel economy.
