I meen you could bust out with 100 or 1000 PSI IF the motor could take it, its the velocity of airflow that bites you in the butt... Thats why you would have to use a specialy shaped compresion tank to do it.
My pops (a verry smart man) said "WHY USE AIR? WHY NOT USE COMPRESSED OXYGEN AND LOW GRADE GAS?" I have been welding for a few years now (for fun and around the house/car stuff) and I have taken a few courses in colledge... Im lincoln electric certified up to 1 1/2 inch <---- i could work on skyscrapers. BUT thats not the point. I was just telling you so that you know I know what Im talkin bout, when you mix oxy with oil or petrolium gasses it explodes! BIG TIME... So why not elliminate the entire need for spark plugs an a batterie? All you would need is a BUTT LOAD of money for motors <---- It would be damn near impossable for any engine to withstand this more that 1 or MAYBE 2 times. However if you could pull this off and make it work, we are deffinitly talkin bout 3-3.5 second timeslips! 
Ok, a couple problems with this. As you said, oxygen mixed with gas explodes. We don't want an explosion because explosions are near impossible to time correctly at high piston speed, what we want is a controlled burn. Using pure oxygen, or even an oxygen/co2 mix is a recipe for disaster, reason: METAL even burns in the presence of pure oxygen. NASA had some astronauts on an apollo mission burn up because the capsule was pressurized with an oxygen rich environment, and a static electric discharge set it off [the tiny spark you feel getting shocked by your car sometimes after rubbing around in the seat in your winter clothes]. After that NASA did some testing and discovered you can get steel wool to harbor a flame in an oxygen rich environment.
Because of this, not only would you "need a lot of money for engines", you'd need a moron to volunteer to drive the car. An oxidizer fuel and pure oxygen, ever heard of rocket fuel? No way in hell you'll get me to drive a car trying to burn rocket fuel in a closed cylinder...
