I know as the bottle empties the pressure goes down so i was wondering, what pressure is a bottle filled to and at what pressure is it no longer safe to use (i.e. it must be filled back up)? Also, do kits come with a regulator on the bottle and if so, what pressure is actually coming out of the bottle and going to the solinoid?
will a bottle warmer keep the pressure up longer?
is injecting behind the tb and safer then infront or does it not matter (wet kit)

other then bigger fuel pump, colder plugs and retard the timing, what else should i keep in mind when buying for the kit? will i loose hp by running colder plugs when not on the bottle and if so, how much?

im sure i have many more noob questions but thats all i can think of right now
thanks guys

THe bottle warmer will help keep the nitrous gaseous for longer. You are looking at about 1000psi of bottle pressure.

Either kit is safe. Some say dry is better for small shots (under a 100) because you don't have to worry about the fuel solnoid falling and causing issues.

Retarded timing and colder plugs will take away power when not spraying. A lot of people run a switchable chip to swith between a N/A timing and a Nitrous timing.

I personally will never spray unless it is to cool an intake charge.

Wet kits are generally calibrated to work between 900-1000 psi, you do not want more than 1100 psi on a wet kit as it will mess uo the fuel/n2o ratio. Yes a bottle warmer will keep the pressure higher, but you will need some way to monitor the pressure. the only way to tell how much n2o you have left in the bottle is by weight. Next time the bottle is empty weigh it, then fill it and weigh it again, now you will be able to figure out how n2o is in your bottle at any time (hint: always use the same scale if you can). The colder plugs won't really hurt much during normal driving (assuming you are only going one or two steps colder) the retarded timing you will feel.

Yes a 10lb bottle means exactly that. There is 10 pounds (weight) of NO2 added to the jug when the bottle is filled.

I don't think it is "dangerous" to continue using the nitrous beyond a certain level of empty bottle. You'll easily notice the power just isn't there anymore, and actually your car will run rich because it is still spraying extra fuel into your engine but no nitrous.

C/Note

you can run out od nos ..and still have 700 psi..i just rap the bottle on the ground and turn it sideways to hear if its got luqiud ....[&:] but you will should no when you run out ... you can run out and still have 4 lbs left in it ...all gas not good..

so if i buy a gauge i can watch for when it falls below 900-1000psi right? do i need a regulator or will that come with the kit?
