Now it’s time to take a look at the hardware that is required to successfully employ nitrous as a power adder. Most nitrous users will start with a kit, the thoroughness of which varies with manufacturer and the intended application. Let’s take a look at a direct-port kit for a 4-cylinder application from Nitrous Oxide Systems that we happened to have laying around the garage. The nitrous is stored in liquid form at a relatively high pressure (around 1000 PSI, depending on temperature) in a tank, which is more commonly referred to as a “bottle”. It’s constructed of high-quality aluminum, and also has a high-flow valve assembly to shut off the flow of nitrous when not in use, as well as a blow-off valve to allow the nitrous to escape if an overpressure situation occurs. It’s important to mount the bottle securely in the vehicle and to treat it with e...
