so normally, on a n NA car, the engine creates a vacume that sucks air from the carb, right?

when you spray nitrous, it is usually se tup to squirt in to the manifold, right? at 900psi(reccomended bottle pressure), what keeps the pressure of the nitrous in the manifold from pusing the gas/air mixture backwards through the carb?

is it just that the engine produces way too much vacume for this to happen, or is it something else?

 

Yes. The pressure from the bottle (900 PSI) is just to push the gas out the nozzles. After its out the nozzles, its no where near 900 PSI. Its turns into a mist or fog, which is then easily sucked into the engine.

well ... first off, let me say that i've never used NO2 before, but i'll offer my take on your question.

i'd guess that when they fill those bottles, it's in liquid form, right? it would require high pressure to keep them that way until it's being used, in which case it would return to gas as pressures equalize, and like rotormotordriver said, get "easily sucked into the engine."

 

Isn't it N20, not N02, lol.
