Direct Port Injection for High Horsepower Applications – 4 Cylinder

For high-output engines, especially 4-cylinder engines equipped with a big turbo, water-methanol injection is an essential part of tuning. Direct port injection guarantees equal mist distribution of the water-alcohol mixture to each cylinder, ensuring no cylinder is overloaded or underserved. This system simplifies tuning and optimizes fluid consumption, making it a must-have for serious performance enthusiasts.

When pushing over 100 horsepower per cylinder, water-methanol injection becomes crucial. At this level, the engine requires additional cooling to keep thermal loads under control. Once you exceed 150 horsepower per cylinder, direct port injection becomes a necessity. It helps lower engine temperatures and improves octane levels, allowing you to move beyond expensive racing fuels while maintaining power and safety in high-performance scenarios.

• Cylinder-Specific Power Gains: Water-methanol injection is critical for engines exceeding 100 horsepower per cylinder.
• Optimal Mixture Distribution: Ensures each cylinder receives the proper amount of the water-methanol mixture for safe engine operation.
• Simplified Tuning: Direct port injection makes tuning easier and more efficient.
• Cost Savings on Fuel: By using water-methanol, the need for racing gasoline is eliminated, reducing overall costs.
