What is the horsepower range this kit offers?

This Nitrous Express kit is designed to add between 50 and 300 horsepower to your engine. The specific output depends on the jetting combination you select and install.

What makes the spraybarless design beneficial?

The spraybarless design eliminates potential issues like sagging, splitting, or airflow obstruction caused by traditional spray bars. This leads to more consistent and efficient distribution of the fuel and nitrous mixture into the engine.

Does this kit include everything needed for installation?

The kit comes with the nitrous plate, solenoids, relay, 15lb bottle, bottle brackets, and supply line. However, you will need to source additional components like nitrous and fuel lines, a throttle-kickdown bracket if applicable, and potentially a fuel pressure safety switch, depending on your specific setup and installation preferences.

About this part

Product Details

If you're looking to add significant horsepower to your carbureted gasoline engine, this Nitrous Express kit is designed to do just that. It's built for 4-barrel carburetors and can add anywhere from 50 to 300 horsepower, depending on the jetting you choose. This system uses an advanced spraybarless design, which means you won't have spray bars that can sag, split, or obstruct airflow. This design helps ensure better fuel and nitrous distribution for more consistent performance.

The Phase 3 series plate is the core of this system, engineered for improved distribution and atomization of the fuel and nitrous mixture. This leads to a more efficient burn and a noticeable increase in power. The kit comes with everything you need to get started, including limited lifetime guaranteed Lightning solenoids, a heavy-duty 40-amp relay, a 15-pound nitrous bottle, stainless steel bottle brackets, and an extra-long supply line. The solenoids are known for their reliability, and the included relay ensures proper electrical control for the system.

This is a comprehensive kit for racers and performance enthusiasts looking for a substantial power boost. It's important to note that this system is not CARB approved and cannot be shipped to California. Always follow the manufacturer's installation instructions carefully, and ensure your engine is in good condition to handle the added power.
