What kind of horsepower increase can I expect with this kit?

This Nitrous Express Hitman kit is adjustable to three different horsepower levels: 100, 150, or 200 HP. You can select the setting that best suits your engine's capabilities and your performance goals.

What is the advantage of the Phase 3 nitrous plate design?

The Phase 3 plate uses a unique design that avoids traditional spray bars. This helps prevent issues like sagging, splitting, or blocking airflow, while promoting superior distribution and atomization of the nitrous and fuel mixture into the engine.

Does this kit come with everything needed for installation?

The kit includes the nitrous plate, a 10lb bottle with a Lightning 45 valve, stainless steel bottle brackets, and other necessary components for the nitrous system itself. However, you will need to source additional items like nitrous and fuel lines, a fuel pressure safety switch, and potentially a purge kit, depending on your specific setup and preferences. Always consult the manufacturer's instructions for a complete list of required components.

About this part

Product Details

If you're looking to add a significant power boost to your carbureted engine, this Nitrous Express Hitman 4-BBL Nitrous Kit is designed to get you started. This system is built around a 4150-style nitrous plate, which fits between your carburetor and intake manifold to introduce nitrous oxide and fuel into the engine. It's a popular choice for those new to nitrous systems because it offers a straightforward way to gain horsepower without a massive investment.

The heart of this kit is the Phase 3 series nitrous plate. Unlike older designs that use spray bars, this plate injects the nitrous and fuel directly through carefully designed ports. This approach helps ensure better distribution and atomization of the mixture into the cylinders, leading to more consistent power delivery. You can also adjust the horsepower output to three different levels: 100, 150, or 200 horsepower, allowing you to tailor the boost to your needs and the strength of your engine. The kit includes a 10-pound nitrous bottle equipped with the Lightning 45 bottle valve, known for its reliable flow, and stainless steel bottle brackets for secure mounting.

This Nitrous Express kit is a well-built option for drivers looking for an accessible entry into nitrous oxide performance. It provides a noticeable increase in power that can change the driving experience. Remember that nitrous systems require proper installation and tuning to ensure engine safety and optimal performance. Always refer to the manufacturer's instructions for detailed setup and operation guidelines.
