Mike,

NASA called, they want you full time on the Manned Mission to Mars project.

Without a doubt, that is the sweetest 928 32v engine on this planet.

Sure, its a turbo, but its running and not breaking after over a full season of racing! (double stinting two classes this season) However, it has busted a axle so far this season.

Yes Mark, that's exactly why the NSX is so powerful, because it has a turbo. A 928 engine should be able to put out over 1000hp with turbos. 2.5 liter 951's can put out 500hp, so it really is a no-brainer.

What is impressive here is that someone took a 65hp/liter NA engine and turned it into a 100+hp/liter NA engine without adding forced induction. And they did it without millions of $$$ in R&D and/or factory backing.

Seriously Mark, do you show up at a neighborhood basketball game with a catchers mitt and a hockey mask? Because that is what you do over and over around here.

I would hope a forced induction motor would have a higher hp/liter ratio, especially one setup for racing.
The Mitsubishi crowd is regularly cranking out 500-600whp (yes, to all four wheels) with 2.2 liters.
