I've learned a thing or two about nitrous in the past, how it's made, how it works, but one thing I don't know is HOW you turn it on. From my understanding, you open the bottle, and nitrous fills up the lines, when you press the engage button, the solenoids open letting nitrous into the engine. Now...how do you turn it off? Do you close the bottle and press the nitrous button to get all the nitrous out of the lines or how do you do it? Someone please explain.
