Hey did you have to press and hold a button to spray or was it the setup that sprays at full throttle. Im asking cause they place im getting mine says it wont fuel puddle and destroy intake manifold,. btw nice car check out my vr6

Awesome.

No problem, thanks for posting!

those above posts are just to clear up any confusion about nitrous, how it works, and when it can cause a "pseudo explosion"

You're correct. It was fuel puddling that caused it due to a faulty window switch.

When the nitrous oxide changes from a liquid to a gas it cools the inlet air temperature by 60°-75°F. A general rule is that every ten degrees of reduction in inlet charge temp equals a 1% increase in power.

rp1809 (November 30, 1999 at 12:00 am)

Released from the cylinder to the inlet, the reduction in pressure causes its physical state changes to a gas. Once the nitrous is injected into the combustion chamber, the temparature reached on the power stroke is high enough to split the nitrous so that the nitrogen and oxygen molecules are separated. The oxygen is burned and the nitrogen helps to dampen the combustion so that the resulting explosion does not damage the internal engine components.

Nitrous oxide comprises of 36% oxygen as opposed to around 21% in a normal atmospheric inlet charge. This ~70% increase in oxygen causes more combustion which coupled with additional fuel means an substantial rise in power. The nitrous oxide is stored in liquid form in a highly pressurised (around 1000psi) aluminium supply cylinder. The size of this cylinder is measured by the weight of nitrous it will carry, and ranges from 2.5lbs to 20lbs.

NOX, or NO2 is not flammable, however the oxygen in it is an accelerant. It takes three parts to forum a fire. Fuel, Oxygen, and Heat. If you have a fire, then blow pure oxygen, or nitrous oxide into it, it will burn a lot hotter. Not to mention that it is pressurized, so that when exposed to a high enough level of heat, the tank will rupture. Pressurized oxygen and fire do not mix, at all. Why do you think smoking is forbidden around houses where oxygen tanks are in use?
