Nitrous Express 4150 Single Entry Crossbar Nitrous Plate Kit Pro-Power (100-500HP) w/o Bottle

If you're looking to add a significant power boost to your 4150 flange carburetor setup, this Nitrous Express Pro-Power plate system is a solid choice. It's designed to inject a precise mixture of nitrous oxide and fuel directly into your intake manifold, creating a substantial increase in horsepower. This system is built around a CNC machined billet aluminum plate that sits between your carburetor and intake manifold, ensuring a clean and efficient distribution of the nitrous charge.

What sets this plate apart is its crossbar design, which eliminates the traditional round spray bars. This means there are no spray bars to sag, rotate, or disrupt airflow, leading to better atomization and more even distribution to each cylinder. This advanced design helps you get the most out of the nitrous and fuel mixture. The kit comes with jetting for a wide range of horsepower gains, from 50 HP up to 300 HP, allowing you to tune it to your specific needs. It also includes a billet aluminum Lightning 45 bottle valve, which is lighter and features improved flow characteristics compared to older brass valves, along with integrated gauge ports.

This comprehensive kit includes everything you need to get started, aside from the nitrous bottle itself. You'll find a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel lines from the solenoid to the plate, nickel-plated fittings, a wide-open throttle switch, a master arming switch, a 40 Amp relay, and the necessary relay harness. It's designed for easy integration with your existing 4150 carburetor setup, making it a straightforward way to unlock more power from your engine.
