... in spades with chocolate on top.
This so called "pressure bleed off" approach only works when you're running a cam that's optimized for a high rpm range, and then only while the engine is running well below that range (in other words, when it's very inefficient and running like a dog). When you get up into the rpm range where the cam profile creates maximum VE (volumetric efficiency), this "pressure bleed off" phenomenon disappears.
Any detonation defense you get from doing this comes from placing the peak VE point so high in the rpm band that the engine doesn't have time
to get into detonation because the compression/ignition/power cycles are happening so fast.
Can it work? Yeah, sort of ---- but to get there you have to build an engine that's only "happy" at high rpm, which means it's going to be a pig under normal street driving conditions.
For a street engine, it's much better to choose a cam that places peak VE in the rpm band where the engine will be living most of the time, and also build it with a compression ratio that is sensible enough to allow it to be happy on the fuel available. There are no short cuts.
