Ehhhhhh ?
We use Co2 to control the Gate pressure on top of base spring and Nitrous to bring the turbo up on converter with the ute. We can only make about 2psi against the converter with pure stall but with Nitrous we can see 7psi in like a 1-1.5 seconds against the trans brake which is moving the 1900HP 88mm XPR turbo fast and that’s the limit we’ve set, could easy go mid teens with extended time
Co2 is a dead gas, it’s $10 to fill the bottle, it’s used as a pressure source only, Nitrous is $200 to fill and uses it’s immense energy to move gas flow fast to spool the turbo
