How does the pumpless system work without an electric pump?

The system uses a pressurized reservoir and a pressure regulator. This setup maintains consistent pressure on the water-methanol mixture, forcing it through the lines and into the intake runners without the need for a separate electric pump.

What is the benefit of direct port injection?

Direct port injection means the water-methanol mixture is sprayed directly into each intake runner, just before the cylinder head. This ensures a more even distribution of the mixture to all cylinders, leading to more consistent cooling and detonation suppression across the engine.

Are there any restrictions on where this system can be shipped?

Yes, this system is not CARB approved and cannot be shipped to California due to emissions regulations.

About this part

Product Details

If you're looking to get the most out of your turbocharged or supercharged four-cylinder engine, a direct port water-methanol injection system can make a big difference. This Nitrous Express Pumpless Direct Port system injects the water-methanol mixture directly into each intake runner, ensuring excellent distribution to every cylinder. This helps to lower combustion temperatures, allowing you to run more boost and advanced timing without risking detonation.

What sets this system apart is its pumpless design. Instead of relying on an electric pump, it uses a pressurized reservoir and a pressure regulator to deliver the mixture. This not only simplifies the installation by eliminating a component but also ensures consistent pressure and flow to each cylinder, which is crucial for optimal performance and engine safety. The system is built with high-quality components, including braided stainless steel AN hoses for durability and clean routing, billet distribution blocks for a solid manifold, filtered nozzles to prevent clogging, and nickel-plated fittings for a secure, leak-free connection.

This system is designed for those who want a robust and reliable way to manage intake temperatures and unlock more power from their forced induction engine. While it offers a significant performance advantage, remember that it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and tuning to ensure you get the best results and maintain engine integrity.
