I just tested a Resonator [sausage like tube, with holes on the inside but
not through the skin] on the ends of my exhaust stacks. I like it. On a
quick test last night, I was able to get 7000 rpm, and still talk on the
radio. The tower man said loud and clear! WoW.
The overall noise was down, and the engine performance was up. I climbed
out
at 120 knots and 1800 fpm ROC. No sound data yet, but just a strong
feeling.
The Resonators are about 13" long, with tube connections on each end. I
got
them from Midas, two years ago. I did not know where to put them as they
are longer than will fit into the engine room. They do not have any
blockage
inside the tube, longitudinally.

Keep checking them Jerry for signs of internal collapse. If they do
perhaps you can copy them in .050 stainless steel.
BTW what psru ratio are you running? We really need some pictures of your
airplane and engine installation. Can you make it to Sun & Fun?
If not where are you?

You are Jerry but Dave Leonard maintains a list of people building and flying
rotary powered airplanes at this web site. http://members.aol.com/rotaryroster/
Thanks for the pictures. Sorry about my confusion on your type of airplane.
There are so many out there flying it is getting hard for me
to keep track of who's flying what.
BTW Leon, notice that Jerry can use part of the stock upper intake manifold.
This is because the RV6A has generous room above the thrust center line.
This is a Tracy Crook style dynamic chamber/throttle body design.
If anybody does not get these two pictures please let me know.
