With any luck, Perry Mick still monitors this list and will respond.
IIRC, his Long EZ is running a stock 13B, even the induction system.
Take a look at:

http://www.bridgingworlds.com/engine.htm

As far as power goes, a late-model 13B with good compression
should yield about 140 HP. That's marginal-to-inadequate for a four-
seater such as a COZY, an Aerocanard or an SQ2000, but okay for
most two-seaters.

Best Regards,

Hi all,

I have been lurking for a little while, reading about all the interesting
experiences around rotary engines.

I am A LONG WAY away from hanging a powerplant on my bird, but I have
started wondering about what I would bolt on.

I read about all the changes and modifications made to the rotary engine,
the cooling system, the oil pans, etc.  Also, the engine controlling systems
and engine management systems that go with them.

Are there any examples of flying RX-7 or RX-8 engines that went straight
from the vehicle to the airplane including its controllers, etc?  What would
the HP be for an non-converted 13B or RX-8 engine?
