Nitrous Express 4150 Gemini Pro-Power Alcohol Nitrous Kit (100-500HP) w/o Bottle

This is the Nitrous Express 4150 Gemini Pro-Power Alcohol Nitrous Kit, designed for standard 4150 flange carburetors. It's a single-stage plate system that directly injects a nitrous and fuel mixture into your engine's intake manifold. This kit is specifically built for alcohol fuel systems and offers adjustable horsepower gains from 100 up to 500 HP, making it a serious upgrade for performance builds.

What sets this Gemini plate apart is its advanced direct-port pattern. Unlike older spray bar designs, this system ensures a more even and precise distribution of the nitrous and fuel mixture to each cylinder. This helps prevent common issues like uneven distribution or airflow obstruction, leading to more consistent power delivery and better atomization. The system is built without spray bars that can sag or get damaged, representing a newer generation of nitrous plate technology. It includes jetting for 100, 200, 300, 400, and 500 horsepower, allowing you to tune the system to your specific needs. The kit comes with Lightning solenoids, which carry a limited lifetime warranty, a heavy-duty 40-amp relay, stainless steel bottle brackets, and an extra 4AN long supply line for your fuel source.

This kit does not include a nitrous bottle, so you'll need to source that separately. It's important to note that this system is not CARB approved and cannot be shipped to California. For optimal performance and safety, always follow the manufacturer's installation and tuning guidelines.
