Designed and manufactured by Harrop to OE standards as a direct replacement for the factory fitted Eaton M45 Supercharger found in the R53 Mini Cooper S. The Harrop TVS900 Supercharger Kit utilises latest generation Eaton TVS supercharger technology, including four lobe rotors (160 degree helix) and revised inlet and outlet port geometry to achieve greater thermal and volumetric efficiency.
Through extensive packaging analysis, the Harrop TVS900 Supercharger is of OE appearance and mounts in the factory M45 Supercharger position using the factory 6PK belt path and tensioner. Along with the Harrop manufactured Supercharger housing, this kit comes complete with a cast aluminium throttle body adapter, billet outlet adapter and heater hose adapter, replacement electric water pump and all ancillary items to complete bolt-on kit. Installation should take anyway between 5-6 hours depending on knowledge and skill level.
