I am  in  the process of designing and building
mufflers.

There are  two kinds  of course RX8
and 13B.

They will look something like  this and they  will
be built from .065" thick  321  SS.

Cost will be several  hundred dollars.


How many  want RX8 mufflers ?

How many want  13B mufflers?

I need more info, but I probably would want a renesis  (RX8)

Fire away on the questions and I will tell you what I  know
so far.

I will take an RX 8 but want to 'hold  off' on the down pipe
from the muffler until I get my engine mounted at the  front of the 337

Thanks

Clive

No problem.

More questions from the heretic.

1.   Would it be possible to make the headers (from the engine to  the
muffler) longer to clear a possible engine mount conflict?

2.   From the Cad, it seems that there are slip joints  between the
headers
and the muffler. Is this correct?

It seems, from my limited knowledge that as the muffler heats up, it will
also expand lengthwise placing  fore-aft stress on each of the three
headers which would encourage cracking. This type of expansion would not
be
accounted for by the three slip joints in line with the aforementioned
headers.
Any thoughts here?

3.   Have you given any thought, or is it possible, to coat the  inside
and
outside of the assembly with "Jet-Hot" coating (outside only  apparently
is
not a good idea). According to some (including Tacy), this puts  most of
the heat out of the system, and much less is radiated from the under  cowl
plumbing.

1. I don't really know. I don't have any 3D's on that mount. I would
suggest
contacting the people that built it for help.

2. Yes slip joints every where. Anything is possible but so far nobody
has had problems of that sort with a tangential muffler and many have
flown. They have had problems but not that kind.

3. Sounds OK to me. If it comes off it goes right out the pipe.

What is the failure mode of "Jet Hot", if it spews big enough chunkscould
you have a Mistral ?

John

I don't think so. I think it comes off in a fine sand like powder.
It least that is what it does when sprayed on a rotor :)
