Using a damper system either dump the hot air out the bottom of the cowl or direct it into the cabin. The only problem I can see with this is the space on the firewall needed to mount the heater core and air plenum. Any thoughts on this? Bob Perkinson Hendersonville, TN. RV9 N658RP Reserved If nothing changes Nothing changes Yeah, Joe. I have an oil cooler core sitting on my side of the firewall that extracts heat from the coolant system. However, the small amount of heat its capable of extracting is so small compared to the thousands of BTU of heat you need to get rid of each minute from a flying rotary that the effect on cooling is nil.

This way you are not making this system part of the engine cooling system and can run lower pressure and be able to shut it off without affecting the engine system. I was thinking of a device that subarus had sandwitched between the oil filter and the block. Any thoughts?
