You guys seem to have a very popular Thermal Barrier Coating (TBC). I was just curious if you have any hard data of thermal conductivity, or even just logs of exhause gas temperature inside of the exhaust versus the relative temperature outside of the exhause manifold or turbine housing? How close of a relationship do you have with the producer of the coating ie: could you get a color change? What I mean by this is you will see a decrease in thermal conductivity if the coating had a higher emissivity. I'm just curious why it always seems that exhaust coatings are black when if they were silver or white they would perform even better...
