What horsepower levels can this kit support?

This Nitrous Express Gemini Pro-Power kit includes jetting for multiple horsepower increases, ranging from 100 HP up to 500 HP. You can select the appropriate jets based on your engine's needs and tuning.

Does this kit come with a nitrous bottle?

No, this is the 'w/o Bottle' version of the kit, meaning it does not include the nitrous bottle itself. You will need to source a compatible nitrous bottle separately.

What makes the Gemini plate system different from older nitrous plates?

The Gemini plate features a unique direct-port pattern for superior nitrous and fuel distribution, avoiding the spray bar issues like sagging or blockage found on older designs. This results in more consistent performance and atomization.

About this part

Product Details

The Nitrous Express 4150 Gemini Pro-Power Nitrous Kit uses a unique direct-port pattern for incredibly even nitrous and fuel distribution, a notable improvement over traditional spray bar designs. This advanced system is specifically engineered to solve common issues found on single plane manifolds, especially those on small and big block Ford engines. It ensures superior distribution and outstanding atomization, meaning you get consistent power gains every time you engage the system.

Unlike older designs where spray bars can sag, split, or block airflow, the Gemini plate is built without them, making it a truly next-generation nitrous plate. This Pro-Power kit comes with jetting options for 100, 200, 300, 400, and even 500 horsepower increases, giving you flexibility as you tune your engine's performance. It fits standard 4150 flange carburetors, making installation straightforward for many performance builds.

Included in this kit are Lightning solenoids with a limited lifetime warranty, a heavy-duty 40-amp relay for reliable power, stainless steel bottle brackets, and an extra 4AN long supply line. While this kit does not include a nitrous bottle, it provides all the essential components for a robust nitrous system installation. Please note this system is not CARB approved and cannot be shipped to California.
