Alloy heads

RAMM said

I wasn't "trying to equate welding with an engine" Your reading comprehension is very poor. I was merely pointing out how much more heat energy a piece of cold aluminum vs pre-heated took to get a nice puddle going --NOWHERE did I say TIG welding aluminum is the same as the combustion process in an ICE. Jesus.

You put it out there like that, as a comparable example. Proof read what you post.

BTW, the head material can only reject heat as fast as the cooling system can reject it. If you can argue that, you'll argue with w stop sign (and you might).

Once the system is up to temp you would need a MASSIVE input of heat across a relatively long period of time to get what you claim. It doesn't happen.

We also know (or should know) that unless something is really wrong, you don't get detonation at WOT.

Most of the time, you get detonation issues and low throttle opening and high load. That's a tuning issue unless you have no clue how to build an engine.
