How does the pumpless system work?

The Nitrous Express pumpless system utilizes a pressurized reservoir and a pressure regulator. This setup maintains sufficient pressure to deliver the water-methanol mixture directly to the intake runners without requiring a separate electric pump.

What is the benefit of direct port injection?

Direct port injection means the water-methanol mixture is delivered individually to each intake runner. This ensures a more consistent and even distribution to every cylinder, which helps manage combustion temperatures and prevent detonation more effectively than single-point systems.

What components are included in the kit?

The kit includes a pressurized reservoir, a pressure regulator, braided stainless AN hoses, billet distribution blocks, filtered nozzles, and nickel-plated fittings. These are all high-quality components selected for performance and durability.

About this part

Product Details

This Nitrous Express Pumpless Water Injection 4500 Carburetor Plate is designed to inject a water-methanol mixture directly into each intake runner. This setup ensures excellent distribution to every cylinder, which is crucial for managing combustion temperatures and preventing detonation, especially in high-performance or boosted applications. It's a well-built system that uses a pressurized reservoir and regulator, meaning you don't need an electric pump, simplifying installation and reducing potential failure points.

You'll find that Nitrous Express uses only the highest quality components in this kit. It comes with braided stainless AN hoses for durability and reliable fluid transfer, along with billet distribution blocks for precise metering. The filtered nozzles are designed to prevent clogging, and all fittings are nickel-plated for corrosion resistance. This direct port injection method is a significant step up from single-point injection systems, offering more consistent results across all cylinders.

When installing this system, remember that it's not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and tuning to get the most out of this water injection system.
