Final single rotor
configuration:
- 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 seems to have less high frequency
components then the previous engine. I have no problem with putting this
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.
