A very interesting Compression Ratio article

I found this while looking for information on optimum quench.

Particularly intresting is the last section, "15 Compression Building Moves." A few on here are somewhat unexpected like "Minimize head chamber volume" and "Minimize heat transfer through common intake/exhaust port wall." How the heck would you do the latter? Polishing them? Apply spray foam? :hissyfit:

To cool the intake tract, David was talking about using a thermal coating. That was a good refresher read.

Gotta ask, what in hell to use for that, that won't under ANY circumstances flake off and make a HUGE mess....

Maybe something like that snakeskin coating? I doubt that latex base would hold up to exhaust heat and fuel mixture, but something similar? Glyptal with the same microbeads?

Just speculating.
