My friend an I were talking about this just last night. Barring the fact that the oxygen would be extremely cold...
I would think that the car would see the mixture change if you were to open the oxygen supply up slowly. So the car would start off of normal air, and slowly change to pure oxygen. In theory, it would slowly add more fuel to the mix becuase it would burn different.
Now for the cold issue, and the fact that the oxygen is compressed. :rolleyes:
