Oxygen is an oxidiser, having more of it allows you to burn more fuel, THAT's where the power comes from. Also, the Nitrogen expands a lot when it gets hot, so cylinder pressure increases even more.
Adding too much Oxygen creates a lean mixture... lean mixtures burn very hot which is how you melt piston heads and rings. Lean mixtures also are prone to detonation... which means the air/fuel mixture ignites before the spark fires... that's bad too... causes pitting and lots of stress on the rotating assembly (among other things).
Blah blah blah... yadda yadda yadda 😀
*EDIT* By the way... I have no idea where you get the idea that adding more air and fuel "increase revolutions." That's stupid... it creates more power, which indirectly increases the RPM range of the engine... but that doesn't mean that's good for the engine.
**EDIT** Also... adding more air and fuel has zero effect on the total displacement of the engine. Displacement is a physical thing that cannot be changed by power adders. It can only be changed by changing the physical dimentions of the combustion chamber... including cylinder bore, stroke, combustion chamber volume, headgasket thickness, quench area, and the size of the piston dish/dome, whichever it may have.
***EDIT*** Hehe... 3rd and final edit... I have a video of an Ultima GTR on a road course passing a whole bunch of different cars. The Ultima GTR is powered by a small block chevy. That the kinda thing you're looking for? If no, I have some videos of "ricers" gettin smoked by Camaro's, Trans Ams, Corvettes, Vipers, Mustangs, etc. Also have some of those same cars being smoked by some "ricers." 😀
