Nitro vs Pure Oxygen

Does the TSX have an O2 sensor on the intake tract? If not, it wouldn't work. Air is about 78% nitrogen and 21% oxygen, with the final 1% consisting of trace amounts of noble gases, primarily argon.
As far as I know the TSX determines the fuel/air mixture to use by reading the MAP sensor (manifold absolute pressure). Because the oxygen content of air never changes, the pressure of the intake manifold is going to allow the ECU to calculate very precisely how much fuel needs to be added to get the engine to run at stoichiometric - the equilibrium - neither too rich nor too lean. If you increase the oxygen concentration of the intake charge without telling the ECU about it, the engine will only get enough fuel for that MAP reading at 21% oxygen. Not enough fuel will be added and the engine will run far too lean, possibly damaging itself in the process.
If the ECU was made aware of the increased oxygen concentration and the fuel system was up to the task, enough fuel could be added to make use of it and you would get some serious power. And just like with nitrous oxide, compressed oxygen would add the benefit of cooling the intake charge due to the phase change from liquid to gas that would occur upon exposure to air in the intake, much like a CO2 cartridge gets cold when you vent it to atmosphere. However to utilize the extra power you would need to ensure that the engine internals were strong enough to contain the explosive force of a fully oxidized mixture without being blown to pieces.
EDIT: it would also be prohibitively expensive. The K24A2 flows about 300 cubic feet per minute at 7,000 RPM.
You'd need welding tanks. SCUBA divers use compressed air. Sometimes they'll use NITROX, which is oxygen-enriched air which is about 35% oxygen, 65% nitrogen. The really deep divers use a twin tank system of pure oxygen and helium as a way of displacing nitrogen from the bloodstream at depths beyond 130 feet. Not that this is relevant, but I used to be a navy diver so I thought I'd add that.

And yes Pure O2 is highly flamable so it would not be suggested to try.

They will make a fuel burn faster and hotter though.

I think I get it.
Thanks!
No wonder that place has a huge freezing tank...

Needless to say, this could mean A LOT worst than engine knock if not well tuned. But properly mastered, it could make for awesome power.
How about a Shuttle-like mix of O2 and H. I'm sure it could work in a combustion engine given the proper plumbing (probably more stable in a Diesel).

Ain't those pure oxygen they are breathing?

Pure oxygen is used for people with breating difficulties, but can also be very useful to speed up the healing process after an injury, for example with athletes.

A spark in an atmosphere of oxygen and a fuel, such as propane, will produce an extremely powerful combustion (as long as the O2/C2H4 mixture is close to stoichiometric).
Have you ever heard of the Apolo project and the 3 astronots that burnt to death from a spark in a pure O enviroment
Pure O is EXPLOSIVE !!!!!!
Key word being PURE

Otherwise a host of problems can occur including increased cardiac load, high blood pressure, and eventually death. It is much healthier to smoke tires than cigarettes...
