ie, don't go crazy thinking SCR is low enough in a calculator. Real world at high rpms will see a completely different story. Don't forget quench can help or hurt detonation as well.
Understand you theory completely and appreciate it.Thing is when you start calling about "real world situations" we both know full well the mechanics in the upper rpm regions in the real world are far,far,from perfect.Valves that are supposed to be completely closed aren't etc.

Now you can experiment on your wallet all you want with pinging engines.But please for the sake of the rep of the forum,the newbies that come on it for advise,re-frame from your risky behavior advise.

I can without doubt tell you that Tech has a good history with hundreds,no thousands of readers.And I have trailing not far behind him involvement in hot rods agree with what he has said.
