Here is a calculator to tell you how much co2 youll need to fill up your chamber to a certain psi at a certain tempurature. just fill min what ever it sais in the box next to it. Example:

psi 100
temp 80

just follow the url to get to my instructable.

ie; PV=nRT in a box?

For those of you that want to do it on your own, so that you don't need a computer with you, do this

(Desired pressure)*(Volume of chamber)=(Mols needed)*(temperature)*0.08206
then multiply the mols needed by 44 to get the grams of CO2 you will need


simplified
(Desired pressure)*(Volume of chamber)=(Grams needed)*(temperature)*0.001865

I believe I used the equation chamber volume in cubic in. * psi wanted/ (temp in Farangeght + 460)/ 26.5

ewwww! empirical units! There is nothing like Kelvin, liters, meters, and grams when it comes to science

yah sorry about that. i just got the equation from the sticky. i just wanted to make it easier. so srry about no metrics.

I did the same in this link (only, when I updated, I added combustion stuff).
