For a P-ported 13B do you have any idea of the flow and pressure the
injected air would need to be at? I am considering it as an
addition to the
Inconel spin muffler.

I have no idea, I strongly suspect that the energy costs of pumping
the air
in would exceed the energy increase in the extraction process.
There were, before widespread use of catalytic converters, air
injection
pumps in an attempt to lower emissions. These operated to inject air
to
complete the combustion of the unburned HC. However I have no idea
how much
power that they took to operate.

The airpump can do double duty.. Some people are still using vacuum
powered flight instruments (quaint reasons, I suppose), and are using
the input side of airpumps (smog pumps) to drive them. So, use the
input side to drive your steam gages, and the output side to cool and
continue to combust the exhaust stream..
PS.. I just got back from Paris and London.. Made it with my Dad to
Duxford and Hendon air museums. What a hoot. Hendon has a magnificent
display. Duxford has a runway... The thing that I found most
interesting was the method that the high performance fighters used to
cool oil and water.. Almost all of them had at least one goofy looking
scoop somewhere on the airframe. Including the Hawker Tempest and
Typhoon. The Me109 had an interesting integration between the wing flap
and heat exchanger. None of these airplanes would be considered slow.

Did you take any pictures Matt?
I enjoyed Duxford too. Did not get to Hendon yet.
Here is a picture or two of the Me109 stuff.
Don't forget guys... closing down first thing tomorrow morning.

Hey Paul,
So does the 109 have a system where they can raise and lower the rad etc. to
control the air inlet size?
John
They can raise and lower one intake lip.
