Nitrous Express Dominator Single Entry Crossbar RNC Nitrous Kit (250-750HP) w/Composite Bottle

If you're looking to add serious horsepower to your vehicle, the Nitrous Express Dominator Single Entry Billet Crossbar Nitrous Kit is a well-built option designed for significant power increases. This kit is engineered for 4150 flange manifolds and is capable of adding anywhere from 50 to 300 horsepower, with additional jetting available to reach up to 750 horsepower. The core of this system is its CNC-machined billet crossbar plate, which replaces traditional spray bars. This design is a notable advancement because it eliminates potential issues like sagging or rotating spray bars, leading to more consistent fuel and nitrous distribution to each cylinder and better atomization. This means you get more efficient combustion and a more reliable power boost.

Included with the kit is a 15lb nitrous bottle featuring the billet aluminum Lightning 45 bottle valve. This valve is a step up from older designs, offering a cleaner flow path with only one 45-degree turn, two integrated gauge ports for monitoring, a 5/8 siphon tube, and a large .325 orifice. It's also lighter than traditional brass valves. Beyond the bottle and plate, Nitrous Express has included a comprehensive package to get you started. You'll find a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel lines running from the solenoid to the plate, and nickel-plated fittings for a clean look and reliable connections. The kit also comes with a wide-open throttle switch, a master arming switch, a 40 Amp relay, and the necessary relay harness, making it a complete nitrous oxide injection system ready for installation.
