Tell that to Koenigsegg, two Rotrex blowers bottom left. Man that engine looks fimiliar. In fact I heard from a reliable source this is the setup in the new GT500.
Edit:
Shit I didn't get to this page yet, leaving it up for a badass mod motor pic
Okay, IMO, Koenigsegg does not equal Ford, GM, Dodge, etc. They make how many total cars a year vs a typical manufacturer?
I do have to say that Koenigsegg did package that well though (from the picture). In my head, Im thinking of a Procharger or similar sitting right in front of the motor. They dont come off as well polished as a roots/ts blower does and would never want to buy a brand new car like that!
