Re: ok this may be a stupid question......
A few yrs back someone was experimenting with using the Mazda twin turbo 1.3B rotary motors and hooking up to an outdrive. Their weight is just a fraction of a BB but of course they made very little torque. Does anyone remember who was doing that and if they had any success?

You still have a lot of horsepower and torque.

just don't go in the ocean, duh...

Yeah, a couple years ago some guys tried to use a pair of import twin-turbocharged motors in a custom built Reno air racer called the Pond Racer. They had all kinds of temp problems with them and it had an inflight engine fire during a run. A highly experienced pilot by the name of Rick Bricker died in the fire after landing the aircraft.
Tried and true parts are pretty well wrung out and new stuff can bite you.
