Hi Paul-

Here are some photos of what I put together to add a heat shield to
the VAM muffler.  The tabs are a 3/4" standoff, and cover roughly
240-degrees of the VAM -- about as much as practically possible.  The
heat shield is .018 SS.  Not much to it really, although getting it
installed was a bit of a challenge given the engine mount tubes.  I
think it is going to do a great job for us.  A bit overkill on the
pictures -- feel free to "edit ruthlessly" to a more appropriate set.

Ran the engine after getting everything installed; with the blast tube
hooked up to the cabin air vents, got lots of toasty warm air just in
the the few minutes of taxiing around.  I suspect routing all the
blast tube air into the cabin will be just too much heat, so we'll
have to think of a way to fabricate some sort of waste gate so we
don't cook.

Thanks Mark. Good pictures.

Hi Mark,
Given the propensity for the rotary engine to melt away
interior muffler parts, please install
a carbon monoxide monitor in your cabin. We don't
want you to die! Would look bad for the rotary ; )
