Ernest,
The heat of the turbo certainly adds to the intake temp if it is running that hot. Most of the newer turbos use water cooling in the bearing/seal section. That helps to isolate the compressor side some. There are some really high temperatures to be handled in the rotary aircraft install. Lynn mentioned the car set up and how he has nothing on the first foot of pipe. In an aircraft there isn't a lot more to the system! If you run a muffler and tail pipe coating or wrapping will help to insulate the exhaust heat from the airplane. In my case I would still prefer Jet-Hot since it looks so much better.

Does the turbo itself add a significant amount of heat to the intake charge?
