    That's true. It's against federal law to fill a bottle that's labeled incorrectly.

    Since we are on the subject I have another question that has to do with this topic..... Ok so one of my friends & I guess some other subaru owners are taking off the antifreeze line that runs into the throttle body. They say it keeps the throttle body cooler.

    My question is would it be possible to run C02 through it before it reaches the intercool sprayer?

    Im thinking that could could lead to something bad... If you would happend to spray it wail at wide open throttle & the throttle body would freeze you could be in some trouble......

    Has anybody ever tried this?

    It's a pretty common modification to do. It's there so the butterfly (the throttle valve) wont freeze shut. Since you live in texas, you're fine doing the mod. Here's the right way to do it: DIY Throttle Body Coolant Bypass Mod - Rexnet Subaru Forums

    I absolutely wouldn't cool the throttle body with CO2

    wise words. not to mention the EXTREME pressure it would see from that causing some sort of chaos...

    That's absolutely untrue. You can get C02 bottles much larger than 10 pounds. After all, a standard C02 fire extinguisher is 20 lbs.

    If you don't ask them, and they in turn don't ask you, don't do it IMO.
    +1 get the right tank for the right gas.

I usually get stuff like that through a local place, called Airgas. If you go to Airgas.com, you can find a place probably near you, call them up and see what they can do.
    +1 as he and many other people have said, nobody legally can fill the tank if it's labeled for another gas.

    Definitely not. I'd use hydrogen for sure.

    Quoted from the Cryo2 FAQ.

    Can I use my old nitrous bottle with this system?
    A nitrous bottle is very similar but the nitrous valve is different from the CryO2 Tank valve and the filling station will not be able to fill it with CO2.

    Call "Harry"

    I called Zex's tech support to ask them this question.... 1-888-817-1008.

    Both gases can use the same tank design.

    The whole thing about the label isn't a huge factor. (most) gas companys have pre printed labels in stock...

    I realy don't think the D.O.T is going to pull me over take out the bottle and test the gas to see if it is the same as the label...

    If it it was a hazmat issue I could understand why this would be such a big factor. like if you wanted to put propane in a C02 bottle.

    Also I maybe should have said this before, but I didn't I weld for a living & Oxygen, C02, Argon, Helium, & any type of non flamable gases all use the same valve.
    Most even use the same type of regulator....


    Ok the big question is this valves issue...

    C02 tanks & Nitrous Oxide tanks both use various types of valves, so the only issue would be is finding a C02 filling station that would accept a Nitrous Oxide tank valve..

    The type of Valve would not realy matter as far as flow of gas, freezing up, ect... The only thing that would matter is having a valve with a dip tube to suck the gas from the bottom of the tank to prevent freezing wich most nos/c02 tanks already have.

    Blah I didn't want this to go this far, but just to give u an idea of how little this valve factor matters...

    No it's an option.

    Another wrong answer. It coats it with pentaerythritol tetranitrate.


    Come on people doesn't anybody here know their stuff?
