Ok look at it this way. The old 308 holden roughly 200 hp and just above 300ci and what 5000rpm and 8 cly. now a Cont 0-300. 100 hp 4 cly and on a good day 2500 rpm. so when you get det in the 308 the cly is roughly half the size of that of the little cont. Now im not sure of the forces but I bet they more than doulble.Hence have a look at the rods and crank in what is just about the smallest areo engine. Then swing a 6 foot prop of it. Now look at a TSIO-540 at full song at around 350hp and introduce det at 2700 odd rpm.
Ive sean an engine that over speed too 2900 rpm after a governor failure for 30 sec. the engine was removed as it was junk.
I've been heavy involved with drag racing over the years detonation kills engines.
Modern car engines run on the limit only due to the electronics that control the engine and they run them like this for emission control and run them as lean as they can. Difference is if they stop you pull over.
