    Designed & Manufactured by Harrop
    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.

Received my order today Fri Mar 5, as usual excellent service with an excellent product,liked the idea that you guys sold the grill as a 2 piece rather than having to order two seperate pieces,like some of the other suppliers, will be dealing with you again in the future.Cheers Bill

I got the lights. Thank you so much. You guys have restored the faith in
humanity to me by sending me the lights because it was so many months
after and it could have been argued that I should have checked the box
sooner and not after 7 months. I am really floored by your customer
service! You guys are awesome!

Thank you !!! :-)


I ordered The chrome tail light frames for my clubman and got them in 3days, they are something the factory should have put on.
They look and fit great .
Also every mini should have a “light in sight”
No more twisted neck looking for the stop lights pete
