Okay, here goes....

If it were mechanically/economically feasable, how much of a performance gain would it bee to rig up a system to feed the engine pure oxygen? Don't know what made me think of this, but since the only truely flammable part of air is the oxygen, I guessed it could potentially be a benefit at the track....

More potent than nitrous...
You'd have to match it with a TON of fuel.

When it expands from stored liquid, it'd get nice and cold, timing galore.

You'd need a nice large heavy tank to store it. And that would supply maybe a couple track runs, if that. You'd need special calibration of the PCM so it would know how to interepret the MAF signal correctly.

Expensive when it'* all said and done.

EDIT: Well, how different would it be from having to store hydrogen in a hydrogen powered car?

I was thinking more along the lines of like a home oxygen tank. But for all I know, they store it in liquid form also....

Like I said, pure brainstorming. Like I intended to imply, no research.....

But, more potent than nitrous??? Wow.....

I was thinking liquid because you'd need a lot to feed the engine just that, a home tank would run out very quickly.

Nitrous is nitrogen and oxygen, same idea as yours, but as a supplement to add more oxygen to atmosperic air.

actually, it'd be easier than hydrogen, because it'* larger... meaning you don't have to worry about the leaking issues that you do with H2...

With the hydrogen, typical concepts use a brick of charcoal or ceramic or something that hydrogen bonds to. The brick is heated and hydrogen is released.

...or something like that...

it would be very easy to blow up the engine. There isnt even 10% oxygen in the air, if you doubled it you would have to double the amount of fuel.

I thuoght o2 was 20ish % of hte atmosphere?

If you blew a small stream before the MAF it might be able to adapt enough.

Interesting idea and before the MAF sounds like a good idea, but since it is pure O2, the content would probably throw the MAF out of wack, since the calculation is based on normal atmospheric content. Even a small increase in the O2 content should be noticeable but how you would modulate that to the fuel needed would be an interesting problem, although a similar setup to NOS would likely work. The scary part is pure O2 makes all kinds of things flamable, not a good thing. I know many years ago they experimented with force feeding dragsters with compressed air, but the volume required, and likely the rules, doomed that experiment.

I think the atmosphere is like 16% O2. Sounds to me like you'd be playing with fire unless your PCM were programmed for it. Even so, I don't think I'd want to drive around with a bottle of compressed oxygen in the trunk. I'd think it would be like a bomb in a rear end accident.
