Like when filling the nitrous bottle hot and it gets air in the tank? How many lbs of air can you actually get in there or can you get any?

Ok thats exackly what I told the guy who filled my bottle but he just wouldnt listen. He says air doesnt have weight... I told him to check out a chemistry class ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
I just wanted to make sure I wasnt the idiot..
So will 10lbs of air go in the bottle or is it less than that?

you would have to compress it to an insane amount to make it have any weight.
plus the only way of getting air to have weight is to compress it into a liquid.
you cannot put 10 lbs of air into an aluminum nitrous bottle and not have it blow up in your face...the pressure would be so extreme.

Air does have wieght, atmospheric pressure. You are measuring weight of air, you know the saying good air bad air. Anyway in the nitrous world, if you filled the bottle with air it would not have enough weight to measure by normal standards. But now he could have filled your bottle with vapor, Vapor has wieght and you can get it to 24.5 lbs. But it is not usable nitrous. I have tracked serveral racer across the country and have found that all had the same problem from time to time. The car does not perform and the purge plume did not happen. They drain the bottls and refilled the performance came back and so did the purge plume. This is also why in a 64lbs. cylinder you can only get ab out 50-53 lbs out of it. The rest is lost, but still has weight. Hope this helps.

Thanks. That was very helpful. 1 more thing tho. He told me that with 4lbs in the bottle you will not be able to use it. He said it would be worthless and I should get it filled again. Even on top of that would be better than trying to run a 100 shot on 4lbs. I have personally ran mine down to 1lb before and had no issues.. Any idea why he said this?

And be very rich conidtion. Now its time for a refill, remember what is in the bottle is not really useful nitrous. So you get your bottle topped off, but you really do not have a complete full bottle of useful nitrous. So keep topping or refilling the bottles off over time but once you notice a performance drop in the car with a bottle that JUST got filled, on your next refill completely drain the bottle. I recommend doing this at the refill place, it will chill the bottle, and help the transfilling for a better fill.

PRessure up sure. I can take a bottle with only 1lb on the scale and get to 1050 psi with a heater. The problem or pressure drop happen the moment the noid opens. You have a much larger area inside the bottle for the nitrous to boil or expand, this causes your systems pressure to fall drasticly and real quickly.
This is also why cars that have pusher system do not run rich on the big end or at the end of the bottle. They are offsetting the boiling by adding nitrogen to the topside of the liquid inside the bottle.

Sounds like Im going to going to a pusher system.
Whats the best size bottle to use so you can get the most of what you have? 5 10 15? Seems like a 5lb bottle would be best and get worse as you go up.
I do keep my bottle in the freezer then put it in a cooler of ice to get the max in the bottle. This last time he told me he would put a vacuum on the bottle to clean it out and then I could definetly get 10lbs of good nitrous.
I searched again but found nothing on the vacuum as well. He said I should do it to my bottle every once in a while and charged $10 extra for this. Is this something you recommend and how often? Thanks for the help.
This isnt the place where the issue is happening however.. I stopped going there and started going to this guy and told him my problem. He said it was normal but I have ran nitrous for 6 months now and never had this problem. Normally I can tell the pressure goes down but I still get a good bit of hp out of the run. With this last 2 bottles that have had the vapor in them I get nothing. At 19lbs last time I only went rich and lost time. Usually I can start a 1/4 run w/ 17 in it and pick up 8 tenths in the 1/4. With a full bottle I get 1 to 1.1 seconds off my 1/4 time.
The other place uses a nos pump and the other guy uses a nx pump so maybe thats why the other guy gets more vapor at the end of the bottle. Or one of them doesnt let it run down as bad.

so you could not put 10 lbs of air into a nitrous bottle and have the seal disc not rupture from teh pressure.
