Nitrous Express Dominator Dual Stage Billet Crossbar Nitrous Kit (50-300 & 100-500HP) w/15lb Bottle

Nitrous Express is known for its performance nitrous oxide systems, and their Dominator Dual Stage Billet Crossbar Nitrous Kit is a prime example of their commitment to advanced technology. This kit is designed for serious performance gains, offering dual-stage capabilities that allow for precise control over nitrous delivery. The core of this system is its unique billet crossbar plate, which is CNC machined to eliminate traditional round spray bars. This design change is notable because it leads to much better atomization of the nitrous and fuel mixture, ensuring more even distribution to each cylinder. Without spray bars that can sag or disrupt airflow, this plate represents a significant step forward in crossbar nitrous plate design.

This comprehensive kit comes with a 15lb nitrous bottle equipped with the billet aluminum Lightning 45 bottle valve. This valve isn't just about looks; it's packed with features like two integrated gauge ports, a 5/8 siphon tube, and a large .325 orifice for improved flow. In fact, it weighs nearly a pound less than older brass valves and has an improved flow path with only one 45-degree turn. Beyond the bottle and valve, the kit includes a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel lines from the solenoids to the plate, and nickel-plated fittings. It also comes with a wide-open throttle switch, a master arming switch, a 40 Amp relay, and the necessary relay harness to get you up and running. The system is specifically designed for DOMINATOR flange manifolds and includes jetting for multiple horsepower levels, from 50 to 300HP for the first stage and 100 to 500HP for the second stage, giving you flexibility to tune your power output.

When installing this system, remember it's designed for specific DOMINATOR flange intake manifolds. The included jetting allows for a wide range of power increases, so you can tailor the performance to your needs. Always refer to the manufacturer's instructions for proper installation and tuning to ensure optimal performance and safety.
