has anyone thought of pure oxygen injection instead of nos it would have to be with fuel and the correct mixture but it would give the engine five times more power because the air we breath it only 20% oxy. I once heard it was quite damaging to engines but not sure. Has been used before in torpedo engines for submarines and a apparently produce amazing power gains. I have a manifold setup for this but im not yet prepared to melt down my babe all for the sake of science.
so are u saying it would blow the engine to bits or could be used well in small portions
Basically that is the whole idea behind nitrous. In the combustion chamber, Nitrous breaks down to oxygen and nitrogen. Nitrous also has the advantage that when it changes state (from nitrous to oxygen and nitrogen), it cools the intake charge resulting in lower temperatures and a denser intake charge.
I work on aircraft and oxygen systems in aircraft. The main problem with pure oxygen is when it comes in contact with other material ie oil, fuel, grease etc etc, it becomes very unstable and helps the other product burn very very well.
Because of this reason when we do any work on oxy systems we have a totaly seperate and clean tool kit which cannot be used for anything other than oxygen maintenance. Even a speck of grease in the oxy lines can cause a fire due to the friction of the oxygen passing through the lines. So personaly i would steer clear of pure oxygen. But thats my opinion. People told me not to put nos on my ute. he he.

elxr6 revs - you're own post contains the answer to your question - ie. you wrote: "...it would have to be with fuel and the correct mixture..." - well, just adding oxygen and fuel alone WON'T give you the correct mixture (defined as fuel/AIR ratio - the "working mixture" internal combustion engines work with) - you'd need more nitrogen as well - and waddaya know? - you've got nitrous!! :s6:
Direct oxygen injection could only be done in small amounts (as ebxr8240 said) - the simple way to think of it is that oxygen alone will at best (ie. with a basically rich mixture to begin with or with fuel added as well) achieve something equivalent to increasing the compression ratio (basically it'll just increase cylinder temperature) - which of course has very finite limitations and lots of dangers to the engine.
Also of course there's the extremely dangerous nature of oxygen (just look at what happened to Apollo 11).
Nitrous oxide is the way to achieve real power increase - it's more akin to increasing the overall capacity of the engine.
Torpedo motors work in a totally different way and can't be related to car engines.
