Hi Jerry,
Good to hear from you. Yes, even rolling your own is
not cheap when it comes to aircraft - especially on retired pay. I
certainly understand your enjoyment in building - I fall into the same
camp. I love to fly, but, find myself mainly doing it to test some
"improvement".
As I said, I'm certainly not against the "P" port and am
looking forward to your reports when you have one up and running. In the
meantime, don't be a stranger.
Ed

template?
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
E-mail Address(es):
jerryhey@earthlink.net
you might send him a
message.
Best
Regards
Ed

[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...
