How does direct port water injection differ from single-point injection?

Direct port systems inject the water-methanol mixture into each intake runner individually, ensuring a more even distribution to every cylinder. Single-point systems inject into the intake tract before the runners, which can lead to less consistent distribution.

What is the purpose of filtering the nozzles?

Filtering the nozzles helps prevent any debris or contaminants in the water-methanol mixture from clogging the small orifices. This ensures consistent flow and proper atomization of the spray into the intake runners.

What is the activation method for this Stage 1 system?

This Stage 1 system is designed to activate automatically when the throttle is opened wide open. This means the water-methanol injection will only occur when the engine is under heavy load and demanding maximum power.

Product Details

This Nitrous Express Stage 1 Direct Port Water Injection system uses a high-pressure electric pump to deliver a water-methanol mixture directly into each intake runner. This setup ensures excellent distribution to every cylinder, which is crucial for managing combustion temperatures in boosted engines. By injecting the mixture at each runner, you get more consistent cooling and charge density across all cylinders compared to a single-point injection system.

The system comes with a composite reservoir to hold your water-methanol blend, high-pressure push lock hose for reliable connections, and filtered nozzles to prevent clogging. For a 4-cylinder engine, this direct port approach is a solid way to manage heat and potentially increase boost levels safely. The Stage 1 system activates via a wide-open throttle switch, meaning injection only occurs when you're demanding maximum power from your engine.

While this system is designed for direct port injection, remember that it's not CARB approved and cannot be shipped to California. For optimal performance and longevity, always use a quality water-methanol blend and refer to the manufacturer's instructions for proper installation and maintenance.
