sure, go for it. Make sure you mount your O2 tank right near the driver seat where you can reach it, and run your O2 line through the floor and under the car. You can zip-tie it to the exhaust pipe, and run it up along the manifolds to the intake pipe. Your best bet would be to put it into the intake after the throttle, however, to prevent the pure O2 from getting heated by the coolant that runs through it. Just mount the tank behind your seat, and reach around and turn the valve with one hand to match your foot on the throttle. If you have a stick, use your left hand for this, and hold the steering wheel with your knee while you shift, or get a good alignment and you won't have to hold the wheel at all while at full throttle. I don't see any problems with doing this at the track, or even for daily driving Hell, if you run it into the intake behind the throttle body, you won't even need your gas pedal - just use the valve on the tank as a throttle - I'm pretty sure this'd work, and it is doubtful there would be any negative effects, regardless of what the haters here might try to tell you.
