   Tested my single rotor today. The first time with some real,
   reproduceable data.
   The configuration is with one compound side housing. The other side
   housing is still sandwiched, using milled down MAZDA housing section.
   This version weight for the nacked engine, flywheel and water pump
   included, is 90lb. This engine is based on 12A rotor and rotor housing.
   Intake is P-P.

   Data:

   RPM    4000
   Fuel flow  2.5GPH
   MAP        21"
   EGT       1400F
   O2         .650  =  15 (ratio)

   At shut down:
   oil temp        200F
   Water temp  200F
   oil pressure was 50psi cold and hot, looks suspect.
   The water pressure gauge did not work, which was the reason for
   shutting
   down after 7min runtime. I had planed to go to max water temperature,
   did not want to do that without water pressure.

   Idling speed is 1300RPM, cold or hot.

   The most interesting fact of this test is the possibility of a power
   estimate. Calculated power using a BSFC of .5 is 30 hp. Looking at the
   power curve of the LeMans engine, this is about 10% below of what is
   shown there. From this, I believe the projected over 100hp at
   7500RPM is
   within reach.
