Interesting reading, more in-depth information on detonation, although it is focused primarily on non-supercharged aviation engines. It shows again the element of heavy knocking or pre-ignition is a severe danger.
These graphs show a non-supercharged engine operating at sea level. At higher manifold pressures, damage will happen much sooner.

I'm pretty happy I drive a turbocharged Diesel
