Garry, perhaps you have experience with the coatings offered for
internal engine components (combustion chamber, pistons, valves etc).
I discussed these coatings with one of the main race engine builders here.
It
seems like a great idea to reduce the thermal transfer from combustion
chamber to engine castings.
However, he reported that engines coated thus showed a net HP loss.
is this consistent with what you, or others have seen?
I have Jet-Hot coated headers. Nice, but no noticeable improvement to
performance.
