Other than it’s an aircooled flat six twin turbo in a C2 N/A shell, I don’t know much. He will not talk about it. Lot’s of talk and speculation on the internet though. I have my own ideas. Awhile back he put down ~1230RWHP and it started a whole shit storm amongst the Porsche community where “pro” tuners and builders of these cars said it was impossible.(video http://www.youtube.com/watch?v=0CwlJaeKQ_k) He’s proved them wrong time and time again. The way it runs now it’s around 1300 RWHP.
