Technically, you can run it as long as you maintain the recommended N2O pressure. That doesn't mean run the bottle dry; with the NX, that's 1000psi. However you're asking for trouble if you hit the track and burn it continuously. It should only be used in moderation, not to mention bottle fills run about $40 bucks. Regarding bottle duration (from earlier in the thread, typical bottle is 10lbs): The formula for calculating your nitrous usage is .8 lbs N2O X 10 seconds = 100 horsepower. I.E. If your system is jetted for 100 horsepower it will use .8 lbs of nitrous for every 10 seconds of usage.

The wet system is an easier install. No need to retard timing, and it utilizes the existing ECU fuel pump directives. If I was going to drag race this car, and get really serious about squeezing 1/10th off, yes I'd probably do a dry instead...
