Lol, if that's actually your name then fair enough.

By the way, good luck getting 3000 psi from CO2. Unless under certain conditions pertaining to temperature it would liquefy before that. And thus, the vapor pressure would be lower.

On the name, a nickname is OK. Really... Especially if you get teased about your real name. I had no idea if it was real or a prank.

Wow, a whole page of pressure references and not one posting of the pressure temperature graph. Well here it is.

I'll keep that in mind, the comercial tanks I will be using are pressurised to 2000-3000 psi but the regulator lowers it considerably to the 800 I will be working with.

hmm, the message doesn't seem to be getting through, you can't get gaseous CO2 at 3000psi at room temperare, period, you'll get liquid or a supercritical fluid if you heat it up.
Maybe the 'commercial tanks' you are talking about are rated to this pressure but the CO2 inside them will never go much above 900psi.
Given this your regulator is somewhat of a waste of time, it will only be regualating down by a 100 odd psi at the expense of flow and space.
I really think you should do a bit of research first and maybe try something a little less extreme to start off with.

maybe get 1200 psi out of co2 in death valley

Perhaps you're using HPA. Are you filling from a paintball site?

CO2 turns liquid above 850psi, which mean's the pressure doesn't increase.
HPA is still going strong at 3000psi, which is what you might need?

Wow. you guys say I don't listen, the tank I am getting IS pressurized at 2000 psi, I am not getting from a paitball site. It is a commercial tank for carbonating beverages... The whole purpose for the 800psi regulator is to keep it a gas. Wow, if you guys would just listen to each other or even read my post as I wrote it I wouldn't have to place posts like this. sheesh...

I don't want to start a flame war, but this needs to be said...
I think you need to follow your own advice, and go read the previous posts. When you do that, you will notice that it is going to be 'impossible' to have CO2 at 2000 psi, because when CO2 is at 850 psi, it becomes a liquid and its pressure does not increase too much higher. It is possible that your tank is 2000 cubic inches... Maybe you should go take a look at it, and if it says "2000 psi" on it, take a picture and then prove us wrong.

It's probably rated to 2000 psi. Mike, people here know what they're talking about. At room temp, or even outside on a very hot day you wont get 2000 psi from CO2, it liquefies too easily. The only way to raise the vapor pressure is to raise the temp, but you eventually will pass the gasses critical point. So no, you won't get that much pressure.

HPA (high pressure air/nitrogen) is available at those pressures, but as it's stored as a gas rather than a liquid it's pressure drops every fill and there's actually less gas in there.

I am sorry if I am comming across as less then pleasent but the site I orderd my tank from assured me it can be filled to 2000 psi. After reserching the nature of the gas I have to agree with you guys as right is right. I will be returning my order from whence it came and ordering a HPA nitrogen set up as has been suggested. When I get everything delivered and assembled I will post pics and video.
