Thought it was common knowledge. I can send you an article on detonation and pre-ignition if you like. This is a little piece of the article for your benefit.
All high output engines are prone to destructive tendencies as a result of over boost, misfueling, mis-tuning and inadequate cooling.
"The combustion event begins with a spark, rapidly builds pressure in the portion of the fuel/air mix that hasn't burned yet, and as that pressure builds, the temperature increases. Once the temperature gets hot enough, the remaining mixture "explodes," causing a hammer-like blow to the piston. "Detonation can cause catastrophic engine failure within a few seconds." For completeness, it is worth mentioning that "detonation" refers to abnormal explosion(s) AFTER the normal ignition. If spontaneous ignition occurs before the spark plug fires, that's a different and far more dangerous condition: "preignition." Either condition can lead to the other, and once they start working together, catastrophic engine failure is only seconds away.
Just for you too... Detonation can be caused by too much spark advance, high IATs, lean mixture, dry air, high ECTs, low octane, etc. It occurs when the spark ignited flame front compresses the reaming air fuel mixture till it reaches critical temperature and pressure to auto ignite the mixture on the other side of the cylinder.
I hope this clears it up for you. You seemed concerned.
Thanks for the reply.
