how much?

Car nitrous is "clean" while dentist nitrous is mixed with oxygen, this is because "clean" nitrous is too strong (in worst case it can kill you).

But when we're talking about Nitrous in a car... i think this added oxygen in dentist nitrous would actually make it run better... though it mihgt create a lil more heat... but it ain't like u're spraying constantly, I don't see it as much of a problem....

You don't want to use dentist nitrous in your car, oxygen is very flamable. And you don't wan't to use "car" nitrous at the dentist.

I think many people have argued about this topic before... I think awhile back on another board, someone suggested use of pure O2 in cars, and that was obviously not good because u're right, oxygen is flammable, and on top of that, pure O2 combustion would produce too much heat and would blow the engine... The nitrous oxide at the dentist isn't pure O2, it IS mostly NO2, true, it probably has more oxygen than normal "car" nitrous, but this added amount shouldn't be too much of a problem, as long as you don't spray like every 10 seconds...

I never said use "car" nitrous at the dentist... that way won't work.... but using dental nitrous in cars should be fine, i've seen it done...

OK, since me and my dentist talked about this while i was waiting for a tooth to be pulled, and since he has a car side, i am confident in what im saying.
Dentists use almost pure NO2. There may be some impurities, but its minimal. Car nitrous isnt as cleanly refined, probably to save on costs, and it probably has an odor agent added (as with natural gas). Dentist nitrous does not have O2 in it. Only when you heat up nitrous does it dissociate into nitrogen and oxygen. You will then have 33% oxygen and 66% nitrogen. In the atmosphere, it is approximately 20% oxygen. This is why running nitrous will provide more power. And cars dont run exlusively on nitrous; its added. So, if you used dental nitrous, you would need a slighly smaller shot of it to achieve the same effective amount of oxygen in the engine.

Here is a grossly wrong, oversimplified way of showing it:
Dental nitrous; 33% Oxygen
Regular car nitrous; 25% oxygen (actually much higher)

to get 10pounds of oxygen, you will need 30 pounds of dental nitrous or 40 pounds of regular nitrous. Then total amount of oxygen remains the same, just, u will need less of the base material (nitrous) to get it.

Also, if they do use sulfur dioxide to add smell to nitrous, i am a little upset, as sulfur dioxide is responsible for acid rain. So, use dental nitrous if possible

Proves my point... that added oxygen in dentist nitrous will add more heat and if u're comparing dental and car nitrous by same amounts, you get more energy(with the added oxygen in combustion) and also heat energy...
