The flow of nitrous oxide from the bottle can also be done remotely
through employing inline valves and bottle adapters. Nitrous Racing offers
both a standard brass power valve and the highly sophisticated Outlaw power
valve with a 1/4-turn activating handle that an be attached to a pull-cable for
outside-the-car activation. The Outlaw power valve has a large .500” orifice to
improve flow, plus an AN-8 flare fitting.
