I think that is down right brilliant. Not only do the gas pulses
lose energy but they are delayed in the spiral passages and
when combined with the straight through gases they noise cancel.
Now if we can make it live with a rotary it might work great.

It's nothin' more than a souped up gas version of the mixing extrusion
nozzles on an epoxy gun!  Son of a gun!  (pun intended).  If you've ever
used one of those ingenious little devices, they work extremely well for
homogenizing the resin and the hardener into a single stream from the two
separate tubes.

I love it when technology skips from one area into another entirely
unrelated one.  Wonder if the folks at Moroso ever messed with extrusion
mixers before?

Has anyone got any exhaust to work that has anything welded inside, away
from cooling, subjected to the full blast of the rotary exhaust? I got the
impression from Ed and Tracy's efforts, that a simple resonator works well
enough, but you need either thick or expensive material. Judging by some of
the simpler designs which have been beaten by the rotary (the fishtails
spring to mind), this looks way to complex to survive. Bet it sounds cool
though:)
