but vapor pressure will vary significantly based on external temperatures.

I would bet that that is no. With the liquid form in the bottle, the pressure would stay relatively stable. Of course, temps would affect it, but not to the degree you see changes with all gas cylinders, like O2, NOS and N2.

You may get a pressure change if things start freezing up, but that is going to be an equiptment issue.

Besides, all it has to do is build boost. As long as it is monitored and properly regulated, it does not matter as long as that compressor can spin fast enough to build boost. I am sure there will still be a good bit of computer control required, but....if you want to play, you got to spend all the money. <img src="/forums/images/graemlins/smile.gif" alt="" />
