Detonation is uncontrolled burning in the chamber. Among other causes, it can be cause by too much ignition timing advance, not enough octane, too much boost (generic term for too much cylinder pressure), or too hot a spark plug heat range even if the car is too rich...

yeah there's too much timing, and I'll be switching to the TR7s. have an a/f gauge and it's pegged rich. the detonation is intermitent. it started after the 2nd run. air charge too hot. can't put an intercooler on so water/meth is coming.
