What is the horsepower range this kit can support?

This single-stage system comes with jetting that can support anywhere from 50 to 500 horsepower. You can adjust the horsepower output by selecting the appropriate jets for your needs.

What makes the distribution 'direct port like'?

The plate injects nitrous and fuel into each cylinder's runner from the side. This method provides a more even distribution to each cylinder compared to a single nozzle or spray bar, similar to a true direct port system but with a simpler installation.

Does this kit come with everything needed for installation?

Yes, the system comes complete with billet aluminum and carbon fiber Lightning Solenoids, stainless steel braided lines, wiring, switches, and every nut, bolt, and connector required for installation. If ordered with a bottle, it includes the bottle valve and brackets as well.

About this part

Product Details

Nitrous Express is well-known for making powerful and reliable nitrous oxide systems. This specific kit is designed to work with Holley Hi-Ram intake manifolds, bolting right between the upper and lower sections for a clean installation. It injects nitrous and fuel directly into each cylinder's runner from the side, giving you a distribution pattern similar to a direct port system without any flow-restricting nozzles or spray bars inside the runner.

The plate itself is machined from solid billet aluminum, with the internal passages created directly within the plate. This construction means you don't have to worry about spray bars coming loose or spinning, which can be an issue with other designs. This single-stage system comes with jetting options that can support anywhere from 50 to 500 horsepower, offering a wide range of tuning possibilities. It includes everything you need to get started: billet aluminum and carbon fiber Lightning Solenoids, stainless steel braided lines, all the necessary wiring, switches, and every single nut, bolt, and connector for installation. If you opt for the bottle, it comes with the billet aluminum Lightning 500 bottle valve and stainless steel bottle brackets.

This kit is a comprehensive solution for adding significant power to your Holley Hi-Ram equipped vehicle. Please note that this system is not CARB approved and cannot be shipped to California.
