Nitrous oxide is used to greatly increase horsepower in full-scale racing
engines. When the N2O molecule breaks down due to combustion temperature, it
releases oxygen. More oxygen means more fuel can be--and is--added. Here's
more info at  http://www.theautochannel.com/content/sports/drag/ms9627.html

Why not eliminate the middle man, the nitrogen, and inject pure O2?

Thanx.

Your engine would explode if you put pure O2 into it.

I may be wrong here, but the general consensus of all the gearheads I talk
with <I'm a gearhead, but not a fan of NO2>, is that the engine would become
an EXTERNAL combustion engine..... and flying parts would ensue, forged
pistons or no......

Also-- I believe you're overlooking the cooling properties of the NO2
injection. That cools the charge, and allows even more mixture into the
chamber.

Indeed, keep in mind we don't even breathe pure O2, there is nitrogen in the
mix. When you mix pure oxegen & a heat source, it goes BOOM!. Just look at
the Apollo 1 disaster.....

I thought that was Apollo 13? Or are you maybe referring to the Gemini
program <I can't recall the launch that burned on the pad>.

Interesting fact- *pure* O2 will actually burn your lungs. IIRC, it's
"cationic" or something- I don't know the exact word, but the meaning was
expressed to me to mean that it would actually react with the tissues. It's
been a long while since I was real interested in that sort of thing, though.
At any rate, you're right- the reason nitrogen is in air is to prevent the
atmosphere from combusting. If I recall my dive science <I'm a little rusty>
air, even with N in it, becomes poisonous at depths of 200 feet in diving-
but oxygen toxicity is another subject entirely. <do I have that right,
Divrdan?>

actually last night i had a dream i put n2o in a r/c lol
the only problem i would see if the increase of heat,and stress to the
engine,but given in small enough amounts to save the engine would make it
not effective enough to even bother with the process of installing it

Pure oxygen makes you feel drunk that's why divers use mixed air.  When
diving at large depths the nitrogen builds up in your ***, you can die if
you come to the surface too quickly.  FYI, with mixed air they use helium in
place of nitrogen so that the diver doesn't die.  Anyway, I'm not a diver
that's just stuff that I've seen on discovery and tlc (I may have gotten
some facts mixed up).

You're more or less right, but I believe you are confusing the "oxygen
drunkness" with Nitrogen Narcosis, also called "rapture of the deep".
Oxygen will actually kill the diver if breathed in too high a concentration,
or below a certain depth, though. I could pull out my cert book, but I'm not
that motivated.. got to go work on my truck's cooling system, anyway....

Because pure O2 reacts with lots of stuff in very dangerous ways.  Think of
Nitrous Oxide as a safe way to carry O2 around.  They do something similar
with cars that run on Hydrogen and O2.  They use Hydrogen Peroxide to carry
the stuff safely.

There are Ultimatly some floors in you idea O2 is the chemical name
for OXYGEN. which you are adding anyway Nitromethane is the
combustable element of the fuel. but as far as i'm aware NitrosOxide
NO2 is created in the cobustion chamber for a microsecond. and
recombusts creating N,C02 Nitrogen Gas and carbondioxide Plus if your
running rich maybe some Carbonmonoxide

Now if you want POWER on the small scale Try adding "Hydrogen" I can
done a few calulations. and a hydrogen gas cilinder could act as a
booster (however i do beleive that you probably would put your heat
sink into orbit....

No, it was Apollo 1, it was just supposed to be a test on the pad, but they
did pressurize the Command Module with Grissom, Chaffey & White inside, & at
the time the module had over a mile of wire strung through it. It was only a
matter of time before some of it shorted, & it turned the***pit into a
bomb, killing all 3 quickly. The problem Apollo 13 had was with a
malfunction that occured when they tried to stir the O2 fuel tank after
liftoff, & apparently something sparked which made the tank blow, so they
had to use the Lunar Module as a lifeboat until they could make their way
back to re-entry. I remember this stuff because I've watched all of the
moc=vies & specials like Apollo 13, & HBO's From the Earth to the
Moon(produced by Tom Hanks), & I watched a Discovery Channel series called
Moonshot, which also covered the whole Apollo program.....:)
