Description

The Nitrous Express Dry Quad Stage Billet Crossbar Plate System 100-2000hp (4500Flange) w/12lb Bottle - 66447-12 is a complete nitrous delivery system designed for significant power gains. It features a CNC machined billet crossbar plate that eliminates traditional round spray bars, leading to excellent atomization and cylinder distribution without airflow disruption. This system supports horsepower ranges from 100 to 2000hp and includes a 12lb bottle with a billet aluminum Lightning 500 bottle valve. The Lightning valve has two integrated gauge ports, a 5/8 siphon tube, a large .500 orifice, and an improved flow path with only one 45-degree turn, making it lighter and more efficient than older brass valves. The kit also includes a custom solenoid bracket, billet aluminum Y-fittings, braided stainless solenoid to plate lines, nickel-plated fittings, a wide-open throttle switch, a master arming switch, a 40 Amp relay, and a relay harness. It is intended for staged nitrous delivery, allowing for controlled power increases suitable for both street cars and track machines.
