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

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...
