Joe and Don,
Bill Jepson and I have been working on the RAM-VAM,
it's ram air in the centre and between the outer skin and the inner muffler
skin. Thr RAM air is assisted by suction at the back i.e. the ram air at the
centre sucks the exhaust and the combined air/exhaust sucks the outer
cooler air.
I have all the pieces and now the manifold
flange but haven't had a chance to assemble it yet - let alone trial it, but
were hopeful it will do the job of cooling the exhaust and making it quieter
without restriction.
The outer skin will act as a isolator to the inner
muffler (in regard to radiant heat) as an added
advantage.
See drawing!

After something Lynn
Hanover said a while back I’m not sure the Tangential muffler would be a good
intermediary to another muffler. Apparently the length of the 2” exhaust
manifold pipes coming from the rotor housing should be a wee bit longer than
you generally have with a tangential (stuck up close the engine). My runners
from housing to big 6” tube are only 4-5” long. I’m afraid that may hurt the
total HP I generate and I’m really more concerned about HP than Db’s J

To Bob White, Jerry Hey and Joe
Hull,
Looking forward to you firing up
your engines and seeing how well the Tangential muffler works. or doesn't
work. If nothing else, it would make a good manifold to run out of to
a SpinTech! Keep us all posted. I'll let you know Bob, when I
figure out where the EC-1 will be placed on the firewall so we know the length
of the wiring.
