OE appearance and operation
Eaton has supplied Superchargers directly to OE Manufacturers for many years due to their reliability and durability testing. The BMW manufactured, R53 Mini Cooper S was one of these vehicles and featured the older M45 Supercharger that had 3 lobe rotors with 60 degree rotor helix twist. Having been a master distributor and technology partner of Eaton for over 12 years, Harrop utilized their OEM design and manufacturing capability to release the world’s only upgrade to replace the aging M45 to TVS900 technology. This upgrade is a bolt on solution and gives an instantaneous performance increase due to the larger and more efficient TVS900 Supercharger and its 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. Further to this, different pulley sizes area viable for the customer who wants even more performance and has the appropriate supporting engine mods and tuning solution.
