the issues isn't JUST cylinder pressures though, just the most simple one to articulate... it's also heat and .. probably plenty of other variables i'm not educated enough to know about... the cooler you can get your cylinders, the more pressure you can add (heat) before the fuels knock point will occur, the 'max' could vary a fair bit depending on specific conditions and variables you're comparing
Yes but compressing and more and more air raises heat as well right?

Whatever, we can discuss what we feel like discussing.
