Sorry, I'm OCD perfectionist, and there's some stuff I gotta clear up.

Not exactly...pre-ignition is when the air/fuel mixture explodes BEFORE the spark plug ignites it. The heat and/or compression in the CC (combustion chamber) causes the mixture to ignite BEFORE the piston has traveled to the the top of the stroke...more on this later. The reason for this is fule that is too low of an octane rating for the pressure or too lean for the heat generated in the engine.

And this unfixed can wear the hell out of your cylinder walls.

The cylinders won't even feel the effects of pinging. The damage is done on the head, piston, and rotating assembly. Of course, when any of these three fail, the effects will be that something goes sideways instead of up and down, and THAT'S when the cylinders get hosed.

which is why you cant have a turbo without an intercooler)

You can have a turbo without an intercooler, it just won't be able to produce as much power. You will be held back by the lack of cooling the compressed air, but it will still work fine.

but the kind of detonation in the pic cant be caused in a N/A, or supercharger. the supercharger spins at the same rate as the engine so the amount of air forced in is directly proportional.

Boost is boost....compression is compression. If you are running 12 PSI and lean out with a SC, it's no different than running 12 PSI and leaning out on a turbo...you will blow the engine up regardless.

turbos have waistegates so when the turbo has the boost level that it needs the excess air is released. if the waiste gate sticks shut then the turbocharger's output flow volume exceeds the engine's volumetric flow, and as you go faster the uncontrolled volume increases untill it pops basically.

Sorta. The wastegate re-directs the exhaust gasses around the turbo instead of through it. The turbo relies on the escaping hot gasses from the exhaust to spool it up, which is converted to mechanical energy via a shaft so that a compressor on the other side can push cool air back into the intake side of the engine. More exhaust means more intake pressure (aka-boost). So once the turbo is where it is supposed to be boosting, the wastegate starts to open to allow the exhaust an alternate path to keep the turbo at that level. The only thing on the INTAKE side of the turbo is the recirc-valve (aka: blow-off valve) that's sole purpose is to relieve the boost levels in the intake piping when the throttle plate closes (letting off the gas) and the boost has nowhere to go....in other words, back through the turbo's compressor which will ultimately cause amage to the compressor and the shaft.

Ok, this turned into an essay afterall!
