A nice engine to go with that?

Developing 685 bph or more then 500 horses on the back wheel

(they are up at over 700 bph now without it blowing to parts as in the video). Also this is a hayabusa engine.
If you wonder why they are doing it the answer is competitions, but they also sell turbos (thats what the company is there for)
