Look, I'm all for discussions, but by your theory, engine temperatures would not go up at all when increasing the power in an engine, because the *friction* would be the same. Right?

I'm all for discussion, too, but you conveniently gloss over or ignore almost exactly half of everything I say so it's pointless.
But to answer your questions:
1) Yes, it's friction in the engine, not the 4500° in-cylinder temperatures, that's the main source of heat.
1.5 Extra Bonus!) In-cylinder temperatures won't be any higher when properly tuned. See: my previous post
2) No, "most" and "all" are not the same thing. ("but by your theory, engine temperatures would not go up at all when increasing the power in an engine, because the *friction* would be the same. Right?")

If you think we are wrong, you are welcome to FI your car to 5~8psi, tune it yourself to run on 87 octane, and run it in the Nevada desert with your foot on the floor to prove us wrong.

I'm not turbocharging a 12.5:1 compression, I'm not doing it on stock internals, I'm not doing it without an intercooler and I'm not running 87 octane. But you can be sure that any time I am in the market for parts, I'll talk to and ultimately buy from someone who can listen to what I'm saying.
