I've seen carbon pistons before. So I guess it can't hurt to try making a compressor wheel out of it. Personally, however, I'd rather see a Beryllium compressor wheel paired with a UBE Tyrannohex ceramic turbine wheel and a TiAl shaft. That would be badass.

Tyrannohex is a pretty neat material. It's about the same strength and density as aluminum, but retains its strength to extremely high temperatures, making it stronger than even the best superalloys at temperatures above 2,000*F: http://www.matweb.com/search/Specifi...assnum=CUBE252

I design furnaces that have the ability to go to over 4000f.

We also made ceramic exhaust wheels for the largest turbo maker. they make almost every wheel for every turbo you can think of. The ceramic wheels are super feather light the only problem they are super brittle but very strong. The only way to damage these wheels are during assembly just tap them and they break but they hold up in cars with almost no therm expansion.
