I need a 400 HP engine that weighs 300 lbs. Is such an engine available?

    400 HP for how long? At what RPM? Is this an airplane or helicopter?

    A 220 pound turbo two rotor will do it but you have
    to pay strict attention to the cooling system design to keep
    the firewall forward weight under 300 pounds.

Sorta off topic...  I just read today that the Sport Class is going to
allow engines that displace up to 1000" (up from 650") at Reno (rumor at
this point)..  I wonder if that means they might let a 4rotor run
(that's only 5.2L or 360" at most)..  I also wonder who they're trying
to let in..  Somebody with a Lyc IO720?

It's an airplane, the cooling will be in the wings and the
power required will be for 10 minutes. chuck

Might be doable but you will have to add 40 pounds to the
dry weight for a prop gear box. If cost is not too much
of an issue (+~ $5000) you can take out 50 pounds by going with
Racing Beat aluminum end housings.
