The carbon muffler was made of a material capable of enduring approximately 300 C (572 F) and was combined with an insulation material. Having said that, during the development of the engine, I was also working on a potential military vehicle and, in this connection, came across a material that can take 1200 C. As a result, the entire exhaust system, from the head to the tail pipe, will be made of this material. As such, the carbon fiber muffler saw only very limited use, i.e., not enough to say it was sufficient for constant and continued use.
I think you'll find when designing and making a full exhaust system using this new hi-temp composite material it will weigh more than if you made it from hydro-formed, fabricated 0.4-0.6mm inconel.
I've seen part of a header system made from the material you describe about 7yrs ago and the results were quite disappointing. Technology moves on so hope you can make it work.
I know of only one material out there that has this sort of performance, without giving it away would I be right in saying its made only by a certain French company??

Just went through this thread for the first time & I must say that I'm stunned by the engineering & execution.
I have a question regarding the steering wheels on both the GS and 930 (assuming your car is the one on a recent Pano cover); were these 'special wishes' wheels? I'm asking because I have one also & have never been certain if it was an original factory part. Yours are the only others I've ever seen.
Thank you for the eye candy.

There is a tremendous amount going on. Porsche Engineering and I have a potential defined path forward which includes, among other things, entirely new four valve heads, a new valve train including pneumatic valve springs and hollow titanium valves and, of course, a modern ECU with the inputs and outputs required for the engine. In short, it could be a rebirth of the air cooled engine at between 500 and 520 normally aspirated HP. The only question now is should it be done and the potential commercial application of it.

Great video! Got to be *the* most major fundermental change for the combustion engine ever. Imagine mapping your own cam profiles like you do for ignition and fueling :-)
