I want to add a supercharger to my car, anyone know where to get one fitted?

I know that the guys at http://www.tdi-plc.com can add one, but I need to shop around and cannot find any other sellers/fitters.

Also anyone here got one installed already.

There is a picture of my engine on my profile if you need an engine type reference for upgrade.

Any help would be appreciated!

Thanks guys...
