    The Only Choice
    for Restricted Nitrous Class Racing!

    These Nitrous Express Restricted Nitrous Class (RNC) Systems are the first choice for professional racers that are limited by jet size. The NX RNC systems are guaranteed to make the most power per jet size of any system on the market. If you don't make the most horsepower or are not 100% satisfied, NX will gladly take the RNC system back and give you a 100% refund. RNC systems are designed to maximize the amount of pure, liquid nitrous delivered through a limited jet size. These systems include special high flow plates, a .250'' orifice Lightning 250 nitrous solenoid, .187'' orifice Lightning fuel solenoid, -08AN supply line and a DF5 bottle valve. Conventional Restricted Nitrous Class systems feature a large orifice center bar nitrous plate that has only one nitrous jet and one fuel jet. Gemini Restricted Nitrous Class systems include a perimeter spray plate that has two nitrous jets and two fuel jets. Systems includes a Lightning series solenoids, stainless hard lines to connect the solenoids to the plate, heavy duty relay, switches, and every nut, bolt and electrical connector needed to complete the installation. Systems with bottle includes the new industry exclusive billet aluminum .500'' orifice direct-flow 'DF-5' bottle valve and stainless bottle brackets.

    Nitrous Express innovates and leads the off-the-shelf nitrous system market! Their systems include the latest technology, designs and the best components available such as the NX Lightning nitrous & fuel solenoids. These solenoids feature an improved flow path that eliminates sharp turns and expansion areas in the nitrous flow path. This keeps the nitrous in dense liquid form which makes more power utilizing less nitrous. Lightning nitrous solenoids feature an integrated purge port which allows you to connect a purge valve directly to the body of the nitrous solenoid for clean looks and less plumbing. Lightning Series solenoids feature CNC aluminum bodies topped with Carbon Fiber cans for the ultimate in weight savings. This kit also includes a Nitrous Express bottle which features the bottle valve against which all others will be judged, the NX 'DF-5'!. The Direct Flow 500, equipped with .500'' orifice and a direct flow, straight through design, is capable of flowing over 2,000 nitrous horsepower. Furnished with a .625'' stainless steel siphon tube and a D-4 bottle refill fitting.
