About this part

Product Details

Nitrous Express is well-known for their nitrous oxide systems, and this Proton single cylinder kit is a solid example of their offerings for carbureted engines. If you're looking to add a significant power boost to a single-cylinder application, this system is designed to do just that. It injects a precise amount of nitrous oxide and fuel to create a more potent combustion event, effectively increasing horsepower.

This kit includes their exclusive "PROTON" solenoid assembly, which is central to controlling the flow of nitrous. You'll also get braided stainless steel hoses for durability and a clean look, along with a Piranha nozzle that atomizes the mixture effectively. The system comes with a fuel pump, relay, microswitch, and arming switch, so you have most of the essential components for installation. It's designed to provide jetting options for 10, 15, 20, or 25 horsepower increases, allowing you to tune the power output to your specific needs. A 2.5lb nitrous bottle and a bottle bracket are also included, making it a comprehensive package for getting started.

Keep in mind that this system is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and safety guidelines.
