Hi Bob,
I am not flying the PP engine yet, however I have a
lot of running time on the test stand. My engine is a single rotor with a 12A
rotor and rotor housing.
The latest tests showed a calculated power of 92hp
at 6000RPM, which, extrapolated to a 13B would give you close to 300hp @
7500RPM.
Don't expect it to idle smooth much below 2000RPM.
I am using a substantial flywheel for preventing gear rattling at that RPM.
This engine has been running now, as it is, for
about 6years on the test stand without any engine related problems. It is ready
to go in the airplane.
Compared to the 100hp SOOB I have been running in
the airplane for 10 years, using the same prop, it is producing at least some
more power.
If I had the size airplane for a 13B it would
definitely be PP.
FWIW.

Is anyone flying with
a Mazda 13B peripheral port engine?
If so, how is it working?
Can you describe the advantages and
disadvantages?
Thanks,
