driving with an open N2O tank

is it bad for your N20 system or your car to have it installed and drive around with it open, with nitrous in the lines;ready to race?

ready to race?
I dont know any other way to drive




but it can lead to a low potency shot -thats why you would purge

I dont exactly know the answer on whether its good or not, but may i suggest an automatic bottle opener. Then you dont have to worry about driving around with it one just flip the switch.

I dont think I ever used to turn the bottle off except to pull it out to fill it
