Damage from Detonation?

Well I have been detonating a 12 a 1972 bridgeport for quite some time, (please dont ask How...very painful to describe). But It has not cracked a bridge, does NOT leak bad things like coolant into the rotor housing still runs but has no power. What are the possible damages done from this abuse? and is there any way to inspect or test without removal and teardown?

compression seals! (apex corner or side), compression test is the quicky

for apex seals you can also look into the exhaust ports with a flashlight, it's not a definitive method though.

is the engine harder to start?

Cars that have suffered detonation have dents on the rotors. Makes them look like they have been hit by a weight lifter with a hammer. When you see what detonation does to the rotors you realise the apex seals do really well to stay intact when detonation occurs.

Yes, what does that mean?

could take out an apex, ruin a rotor and a housing (from experience that is)

Believe it or not the apex did go out the exhaust. If I had a turbo it would've been way more expensive.

Think about it...
Normal combustion pressures are about 1000psi or so.
Detonation can cause combustion pressures to spike up to 10 TIMES HIGHER.
We're talking 10,000psi!

You think that would cause havoc?

How Long?

How long did it take for that to happen, did the engine still run before you tore it down?
