Hi Ed,  I am still here and still working on engine development.  The on going project is the S-beam engine mount which now comes with a custom oil pan. It is a good deal.   I am still very committed to p ports and can bore housings, supply inserts and so on. I love the rotary engine.  I don't say much over here because I might slip up and mention Paul Lamar in a favorable light. I don't want to cause anyone to have a heart attack.    
  
Unfortunately, my retirement income does not allow me to maintain a plane.  Hanger rent, insurance, etc.    I sold my  flying Tailwind but I intend to resume work on the rotary powered one this winter.  Eventually it will be sold as a project  but not until it is finished firewall forward.  I've slowly come to realize that I would rather build than fly anyway. 
 
 Life is good.   Regards,  Jerry

Hi Doug,
 
If you want to develop between 160 and 170 HP from a 13B, I for one would not consider a P port.  The reason, is that the stock 13B will easily give you that kind of power with less effort and cost.  If you wanted HP on the order of 200 + then a P port might be one approach to consider. 
 
Now if you simply want to experiment with a P port, then got to it.  But, it is simply not needed for the power levels you are looking for.
 
The only person I am aware of who may have the information you want is Jerry Hey - he use to be on the list, but I have not seeing anything from him recently.    This is the last e mail address I have for Jerry Hey

you might send him a message.
 
 
Best Regards

Subject: [FlyRotary] P Porting template?

I have a friend in Denver who is willing to set up his milling machine to mill out some P-Ports on a couple of my old rotor housings over Thanksgiving break.  My question is if any of you know where I can get a copy of a template for use with 1.5" diameter intake pipes.  I would think there would be something in the public domain by now (but I could be wrong).  The potential benefits of a P-Port make it pretty attractive to at least experiment with at some point and I will be happy to develop between 160 and 170 hp in my 9A so I think that should be doable...
