Everybody else will think I have gone off the deep end.

We knew that long time ago Paul :)
That manifold looks bigger than the engine? There is no way it will
fit in any engine. You'll have to shrink it somehow.
Buly
Have you seen the RX8 engine stock manifold? Here is a picture.
It is no larger than this but it is lower in case somebody
wants to put it in a Porsche or Miata. Sports car engine
compartments are wider than they are high. Especially rear
or mid engine sports cars. It actually trades
off peak power for low speed torque.
It is not for your airplane anyway. You don't need torque
at 2500 RPM to 5000 RPM so dynamic chambers are useless.
I have made some aerodynamic improvements. It is now classic
Mazda dynamic chamber except it is variable length.
------------------------------------------------------------
Lots of people have tried copying the Mazda dynamic chamber
for aircraft with mediocre results. They did not realize why
it was the way it was. In other words its real purpose was to
generate torque at 2500 to 3000 RPM and not HP in our range.
Me included in the early years of this newsletter.
If you want to try the principle and you don't have room
or height over the engine for 25 inch long manifold runners you
could try something like this. It would be much simpler
and easier to make for a P-port engine.
It does not work in the real high speed range (9000 RPM and up)
as the runners are too short for that. It only works in the
dynamic chamber mode at around 5000 to 8000 RPM. You will give
up a bit of power over conventional 25 inch runners but I don't
know how much. It has never been tested or dynoed to my knowledge.
A lot depends on the details. Of course it is not easy to make
for a four port engine and you may need soluble tooling
to build a composite version. Here is how to do that.
