The Lancair Super ES (TSIO 550E) normally takes the cabin heat from the sonic venturi ports on the induction air system.  This does not provide very much heat, it is extremely noisy, and what heat is provided is lost in decent when power is reduced and the turbochargers are not in demand.  In pressurized airplanes ie. LIVP and Piper Mirage, the heat is provided through the pressurization system and these problems are eliminated.

I have contacted Aerospace Welding Minneapolis, manufactures of several exhaust systems for many different GA aircraft, about making a heat muff system for this engine.  They are willing to look at manufacturing a heat muff shroud that would wrap around the R/H exhaust pipe. We looked at the turbo crossover tube but there is not much clearance between the tube and the firewall.

Is anyone interested in this type of system for their TSIO550 powered ES?  I am trying to get an idea of how many systems could be produced at one time if a group order were placed.  Also, would anyone be willing to part with their r/h exhaust pipe for evaluation purposes?

Thanks,
