Kelly,  

Ye= s, I have the 20B OMP.  I took it apart tonight and tried to figure it o= ut.  It has two solenoids.  Best I can determine, they take the pl= ace of the mixture adjustment rod assy. on the 13b OMP.  In other words= , they move the barrel valve in and out, changing the oil flow.  With t= his figured out, I could probably make it work for my purposes by locking th= e solenoid plunger in the fully open position.  Or, I could try to figu= re out what the solenoid's nine wires do and then design a circuit to contro= l it based on MAP, RPM, etc.  Since I'm not an EE or a programmer, that= isn't likely, so I think I will just lock it open and use a little more oil= .

BTW, the 20b OMP has 4 outlets, but one was plugged at t= he factory.  So, it only uses 3 outlets.  I think in the long run,= it will be easier to use the 20b pump, and it should be a better match than= the 13b OMP.  I may try a flow test if I can figure out how fast to sp= in it to simulate 7000 rpm.  At least I could compare the flow of the 1= 3b to the 20b.   

Tracy - can I exchange the 13b OMP adapter (just arrived= today) for a 20b OMP adapter?

Mark,

 

Since the OMP 's I've seen are set up with 4 oil lines and= intended for a two rotor engine, how do you intend to adapt it to the three= rotor engine in terms of amount of oil metered and how it is distribut= ed?
