diesels. 13.5:1 comp and 84lbs of boost seems like it would produce a helluva lot more, but then again I can only compare it to a gasoline engine. I know of a couple hondas locally with low compression and ~35lbs of boost making ~700whp (on race gas obviously), and K series engines have achieved over 800 as well. Maybe that's just an apples to oranges kinda thing though?
