TVS900 Supercharger Kit

The Harrop TVS900 Supercharger Kit represents a significant upgrade for the R53 Mini Cooper S, replacing the original Eaton M45 Supercharger with advanced Eaton TVS technology. This kit leverages a 4-lobe rotor design and a 160-degree helix twist for enhanced efficiency and performance. Designed as a direct, bolt-on solution, this supercharger kit mounts in the factory position, integrating seamlessly with the OEM belt path and tensioner. It also allows for the use of factory or aftermarket intercoolers. The kit includes a cast aluminum throttle body adapter, billet outlet adapter, heater hose adapter, and a high-volume electric water pump with all necessary ancillary components for installation. Harrop offers various pulley sizes (70mm standard, with optional 65mm and 60mm for higher boost) to cater to different performance needs. The standard 70mm pulley kit does not require a separate tuning solution but enhances supercharger efficiency. For customers seeking maximum performance with supporting engine modifications, the smaller pulleys provide higher boost levels. This kit delivers an impressive performance increase, yielding 188hp and 164 ft-lbs of torque (+30hp / +12 ft-lbs over stock) at 16.4 PSI, as measured on Harrop's dynamometer.
