Paul,

here is some more information on my single rotor just for the records.

- Rotor housing/rotor is MAZDA 12A
- Intake, P-Port with 23.5" runner length
- Carburetor, 38mm round slide.
- Ignition, Street Fire MSD triggered with RX8 CAS.
- Redrive, Hirth G40, 3.33 : 1
- Alternator, Kubota after market with regulator.
- Muffler, 5" diameter 12" long tangential input with 1.18" ID exit
pipe.

Shake down testing is going well. No problems so far after 30Min
runtime.
Most of it at 6000RPM static with WOT. Load is a 3blade 72" IVO prop.
Exhaust noise seem to have less high frequency components than the
previous engine. I have no problem putting the same muffler on the
air plane.

I still plan to go through a range of loads from about 3500RPM to
7500, all at WOT.

I will keep you posted.
