what happens when you run out of nitrous in the middle of a run?- you get pooling in the intake runners and intake manifold go boom????? just a guess cause i havent had it happen yet but i dont want it to either

 

Nope when it runs out of nitrous it just sprays a **** load of fuel in there but it doesnt puddle in there and nitrous doesnt just run out. It gets weaker and weaker after 800psi the power drops quickly. After 600psi you should just go ahead and shut it off cause at that point with a wet system you are just running the motor really rich. I have run 35 or so bottles through my truck and didnt have it happen. I ran it a couple of times down to the last little bit when I was new to nitrous and it didnt blow anything up.

 

so nothing should happen-

 

i always check my pressure and also weigh the bottle full. then keep track of how many times i spray. the best thing i can recommend is to keep weighing it.

 

Nothing for the most part should happen at all. You just run super rich if it is a wet kit. If it is a dry shot, nothing happens, just air gets blow in the motor.

 

With a dry shot you just slow down.

 

what about if i have nitrous and i want to supercharge my 5.7 tbi ?

 

go ahead just make your shot lower- start w/ like a 35 shot and work your way up checking the AFR as you go up

 

Mostly it just gets pumped out at higher rpms. Problems could arise snapping throttle shut at end of then nailing it again at lower rpms. Listen to a wet kit run at the end of run on deceleration, you often hear popping out the exhaust, this is unburned fuel. Under the right circumstances, it could be an issue, but likely not to happen for most, but certainly a possibility.
