6800 1900 2400
7200 1925 2600
7600 1920 2750
8000 1800 2700

Those are insane hp/ci #s, however I think the longevity may come into play in anything other than a drag car.....(you may get 5 or 10 min @ WFO in a boat), what a great 5 or 10 min though :)

10 pounds would still be 1200HP. Would that last?

Marty I went 180 hrs. before a rebuild on a 1200hp twin turbo 572. So yes it can last.

Man, that's gotta hurt the "oudrive repair" pocketbook.
