Re: [FlyRotary] 20B exhaust (so far)
Buly - I discussed this very point with
my welder at great length. He has a lot of experience fabricating exhaust
for race cars, including rotaries. We decided to chance not using the slip
joints based on other cases where he didn't use them. They can always be
added if deemed necessary. I will have a ball joint ahead of the
muffler. I hope to have some dedicated airflow over the manifold
also. My guess is that this whole system will be changed as I learn more
of what I really need.

Hi Kevin, I believe you must have some slip
joints there to allow for expansion. Without them you may get some
cracking.

I have my engine upside
down right now while I work out oil cooler location. My welder gave me
some 321, so that's why the front rotor has an additional weld. That
plywood box is a spintech muffler mock-up, although it's not in place.
I plan to run it against the fire wall. With my belly scoop I
can't run the exhaust down there (damn!), so it will go out the side, a la
turbine engine I guess. I was lucky to have the welded up part able to
slide on around the engine mount, easy to forget when you are playing with
individual pieces.
