Tested my single rotor today. The first = time with=20 some real, reproduceable data.
The configuration is with one compound = side=20 housing. The other side housing is still sandwiched, using milled down = MAZDA=20 housing section.
This version weight for the nacked = engine, flywheel=20 and water pump included, is 90lb. This engine is based on 12A rotor and = rotor=20 housing. Intake is P-P.
 
Data:
 
RPM    4000
Fuel flow  2.5GPH
MAP       =20 21"
EGT       = 1400F
O2         .650&nbs= p; =3D  15=20 (ratio)
 
At shut down:
oil = temp       =20 200F
Water temp  = 200F 
oil pressure was 50psi cold and hot, = looks=20 suspect.
The water pressure gauge did not work, = which was=20 the reason for shutting down after 7min runtime. I had planed to go to = max water=20 temperature, did not want to do that without water = pressure.
