I got a chance to play with a mini-cooper s at a friends local airport today for a little. I think it was an s anyway, definately supercharged. Could have been turbo, but sounded more like a supercharger. Good driver too, but it didn't quite keep up with me on any of the runs, even from a roll. Sounded like he had a BOV, dunno about any other mods. My mods are aftermarket catless up and down pipes, a 3'' bosan twin-tip turbo back, and an EJ255 hybrid with the heads, turbo, & intercooler from the original 2.0, STi injectors.
