Hey Mark;
We've been looking at the same
things with our install. We talked to our exhaust guy, and he feels that
with the exhaust temps that these rotaries have, that it might not be a good
idea, (the muff). Next step was hot water, plumbing, and a heater core
inside some where, which was sort of a negative idea. We kept all of our
cooling lines exterior, so that a coolant leak wouldn't happen inside at about
10K feet, and 200+ knots, not a good scenario. J.C. Whitney has a small
electric heater that has some possibilities, so we are looking into that and
some other ideas.

Cooler)
Jeff,
I'm considering going to a heat muff since there is sooooooo
much exhaust heat that's just going to waste. I was going to incorporate
it into the heat shield of my newest muffler design. Of course, I'll
need to add a CO detector in the cabin for safety.

Well with 3
coolers already, I didn’t want to add a heater core and all the plumbing – I
may move my scavenge point from oil cooler to water radiator as it is below
the engine (uphill for warm air) and closer to the firewall (fewer corners
to turn). I picked the oil cooler because at the time my oil temp was higher
than water temp – now it’s the other way around … also the outlet of oil
cooler as installed is less likely to get contaminated with exhaust
fumes.
