there is a youtube link in it of a 325 that sounds amazing. the title has kompressor+turbo in it.

That car has a twinscrew type supercharger working with a Turbo. Its an euro S52 engine placed in looks like a 325ci e46. I also love the way its sounds, but that thing is way custom.

edit: Wait crap I'm thinking of the other hypercharged car.... How many of these damn things are there.
