Nitrous Express 4150 Gemini Pro-Power Nitrous Kit (100-500HP) w/10lb Bottle

Nitrous Express is known for making advanced nitrous oxide systems that help racers and performance enthusiasts get more power from their engines. This 4150 Gemini Pro-Power Nitrous Kit is a prime example, designed to give you a significant horsepower boost for standard 4150 flange carburetors. It's a single-stage plate system that uses a unique direct-port pattern, which is a big deal because it ensures a more even distribution of nitrous and fuel compared to older spray bar designs. This means you get better atomization and more consistent power delivery, especially on single-plane manifolds like those found on many small and big block Fords.

What sets this Gemini plate apart is its advanced design that avoids common issues like spray bars sagging or blocking airflow. It's built for serious performance, offering jetting options for 100, 200, 300, 400, and even 500 horsepower increases. This kit comes with everything you need to get started, including a 10lb nitrous bottle, heavy-duty 40-amp relay, stainless steel bottle brackets, and a long 4AN supply line. The Lightning solenoids are backed by a limited lifetime warranty, giving you peace of mind when you're pushing your engine to its limits.

This system is available for alcohol applications, and while it's not CARB approved and cannot be shipped to California, it's a solid option for those looking to significantly increase their engine's power output. Remember that installing a nitrous system requires careful attention to fuel delivery and engine health, so always follow the manufacturer's instructions closely.
