Hi Everyone,

I am strongly inclined towards installing a Rotec R2800 engine on my S7SS. I am wondering if anybody who has gone this route has successfully installed a cabin heat system to go with it. Scouring the web, I have not been able to find much of anything so far.

I am thinking of a couple of ways:

a) I would fabricate a shroud that would fit around the exhaust ring and feed the outside air through the shroud which in turn goes into a box where it would be mixed with unheated cabin air. Much like in C-172. Or

b) I'm not sure this would even be possible but I would install a heater core with a fan on it and route the engine oil through it (since this is an air cooled engine and there is no coolant). The oil coming out of this core would be fed back in prior to the engine oil filter. In this case I wonder if the core would be able to withstand the oil pressure. Should I use an oil cooler instead?

I welcome any idea.

Thanks in advance!
