Wrong again and wrong.
Heat spools a turbo faster, that's why it's best placed close to the engine--where the exhaust gas is hottest and thus most energetic. Everyone seems to grasp that flow of air through a turbo makes it work; however, few seem to fully appreciate the interrelatedness and importance of the heat portion of the equation. I doubt you would argue with F=ma, so I baffled why PV=nRT is such an issue.
Further, an "explosion" in the combustion chamber i.e. an uncontrolled burn of the fuel air mixture is a side-effect of detonation, and is VERY dangerous for an engine. What you want is a nice clean burn front that emanates from the spark and burns in a controlled manner towards the periphery. This ramps pressure up on the piston safely as well as extends the period which the burn produces pressure (i.e. torque). This is why slower burning fuels like diesel make so much more torque. And just as discussed earlier, that pressure is a result of the heating of the air through combustion of gas and oxygen.
I know these boards are for fun and collective education, but you should really be careful when pontificating about subjects which you don't seem to fully grasp. 10 people have probably read that and been like -- "OK, so how do I get more explosion in my cylinders?"
