Direct oxygen feed to an engine - stupid idea?

[FunkyNige]

Whilst a few mates and myself were in a pub a while back we had a cunning plan - since Nitrous Oxide works (or so I've been led to believe) by incresing the amount of oxygen going into an engine, wouldn't it be best to just put a bottle of pure oxygen in?
Another idea we had was to put an oxygen feed into a turbo, so when the turbo operates more oxygen than normal is available to help with combustion.
Am I being stupid or will this work?

Bleh, another good idea put out of action by rational thinking.
