I don't understand the above. TBC's applied to the combustion chamber,
piston crown, valve heads and the exhaust port, tend to reduce the
waste heat that appears in the cooling system while increasing the
waste heat that appears in the exhaust. This is based on comments from
people running turbos who take a particular interest in the exhaust gas
temps and how much energy they can recover from that source.


First, the sentence above should have been, "Do 'not' know for
guaranteed the the cooling will be sufficient,"

But I understand better now. I was thinking that the inside of the
rotors and coolant passages would be coated with the dispersant to help
pull the heat out of the metal and into the cooling fluids. The fluid
temps would be higher, even though the actual metal wouldn't be.

This is by far the hardest lesson about freedom. It goes against
instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
