Power TV has a video clip of a twin-turbo Challenger, built by RDP Motorsports for this year's SEMA show. It is awesome.

While motor wise this is already a well built beauty, it's all around attention to detail in just about every item on the car is even more amazing. It's certainly well beyond my means, but it sure would be awesome to get your hands on.
