Now THAT would have been good if it happened in the fast and the furious cars

NOS = nitrous oxide right?
That's just nitrogen and oxygen, 2 commonly found elements int he air that we breathe. I'm just curious if it is flamible on its own (i doubt it) or extremely flamible when combined wiht petrol ( probbaly).

It was parked in his garage at the time... the bottle exploded.
The pre-heater did not turn off properly and overheated the contents and kaboom.
I saw the full website a few years ago. It had heaps more pictures and a step by step analysis of the explosion. I have it somewhere on CD if anyone wants to see it all.

anyone can correct or clarify this but nitrous oxide is nitrogen and oxygen, just like air mostly is, but instead of being separate elements that exist together NO2 is an element on its own.

Nitrogen is an element
Oxygen is an element
Nitrous oxide is a compound
just out of curiosity whats laughing gas ?

from my understanding of NOS, it doesnt actually burn itself, rather reduces the tempreture inside the cylinder to something really cold and thus more air can get in (more air can fit rather, being the cold makes it more dense), making the fuel/air/spark reaction oh so better.

not really. this has beeen discussed before, but I'll go through it again.
the compound of nitrogen and oxygen is held together by bonds. when exposed to enough energy (heat) these bonds can be weakened and broken, like the heat in the engine of a car.
when the bonds are broken, you get oxygen and nitrogen released.
the nitrogen has no effect, but the oxygen is what allows the fuel to burn, so you're getting more oxygen in the engine, thus (if tuned correctly) you can put more fuel in there to combust.

the same: N2O
the medical stuff is much cleaner than the automotive grade stuff (no oils, contaminants, etc)
note: NO2 is nitric oxide, N2O is laughing gas or nitrous oxide
the N2O assists combustion:
- it requires less energy to remove the O2 from nitrogen as it does water H2O or carbon dioxide CO2 - so the N2O is a willing participant in any oxydizing reaction such as burning petrol
- you help 'saturated' the atmosphere in the combustion chamber with compounds that release a great deal of energy when they oxidize (e.g. lots of extra fuel and very cold, dense NO2 gas)
- horsepower comes from the massive amounts of fuel and all the extra O2 released form the NO2 when heated and compressed in the combustion chamber, e.g. a much bigger bang when the spark plug lights up. If you get this mixture too lean (e.g. not enough fuel) expect the engine to die within seconds from massive detonation and pinging? i think you would want to run slightly rich if using N2O? 
important note: the explosion probably wasn't from the N2O burning - but from the massive release of pressure when the bottle opened up - N2O needs a fuel to oxidize with if you want lots of heat & energy - some of it will have reacted with water and other nearby stuff, but not in the way it performs in the combusion chamber. The heater (that led to this catastrophy) is to keep the gas bubbling off and to prevent the liquid N2O from freezing as the tank pressure fell from gas take-off.
... and all you ever wanted to know N2O (regarding your body):
It leads to loss of balance, loss of awareness of any stimuli, including loud noises, and speech, sharp mental deterioration and eventual lapse into unconsciousness.
The main effect is depression of the central nervous system, including the brain, stem and spinal cord, which eventually stops involuntary actions including breathing, partly because of the effect of the gas itself, but also because of oxygen deprivation.
A person rendered unconscious by nitrous oxide is likely to stop breathing within a few seconds. All it takes is a series of breaths without oxygen in between. If a person remains conscious and stops breathing the nitrous oxide, full recovery is likely within minutes. However, someone who continues to inhale the pure gas after losing consciousness will almost certainly die.
(search Google for "laughing gas NO" to find more)

nos is under extremely high pressure and is highly flammable i think

no its inert.. that the point of the last post.
basically to break it down
N20 (naaaaws) =
More molecules of oxygen per mole than air +
Compressed and therefore colder (when released) air
in escense similar to an turbo + intercooler (more oxygen available for combustion)

This is the same concept behind ethanol...
theres an oxygen atom in the ethanol hence there MUCH better complete combustion
but unlike NOS is not under pressure and is not a Gas

from my understanding, NOS is merely a fuel inhibuter (additive)... it doesnt burn as such but when it is super heated (heated up quickly) it expands at a VERY rapid rate which is where you get the power from... quicker expansion upon the power stroke of a motor means more power.........
mmmmmmmmm... more power!!!!

Did you read thechuckster's post? He covered pretty much everything. Rapid expansion has nothing to do with the power increase provided by N2O.
So much misinformation in this thread! 
Those pics are pretty sobering though. N2O is stored at approximately 800psi from memory, but the defective safety valve let the pressure climb much higher until the cylinder itself eventually failed. The sudden release of that enormous pressure caused a shockwave which tore the car to pieces. Can you imagine what it would have been like if that was a flammable gas, like LPG for example? It probably would have taken out the entire house and half the neighbourhood!

Thats Why LPG tanks have to be tested every 10 years, LPG tank vs Petrol tank your safer with an LPG tank in the back!
even then i think the odds are more in favor of a flywheel comen off thru the floor and taken your legs off then petrol tank exploding unexpectedly
shitty N2O installs on the other hand are bound to cause much pain!
