RTMG Performance Dual LPFP Upgrade Kit for EA888 Gen 4 Platforms

RTMG Performance Dual LPFP Upgrade Kit for EA888 Gen 4 Platforms

The Ultimate Low-Pressure Fuel System Upgrade for High-Power EA888 Gen 4 Applications

The RTMG Performance Dual LPFP Upgrade Kit has been developed specifically for EA888 Gen 4 vehicles equipped with the latest OEM brushless fuel pump system, including applications such as the Volkswagen Golf R Mk8, Audi S3 8Y, Audi TTS 8S and other compatible MQB Evo platforms.

Designed and tested on high-performance builds, this complete fuel system upgrade supports up to 1300 HP while maintaining OEM drivability and everyday reliability.

Unlike conventional dual-pump systems that operate continuously, the RTMG solution intelligently combines the factory brushless pump with a secondary Walbro 450 fuel pump, delivering fuel only when additional flow is required.

Key Features

• Supports up to1300 HP applications on gasoline.
• Retains the factory brushless fuel pump
• Secondary Walbro 450 high-flow fuel pump
• CNC-machined billet aluminum pump mounting system
• Hard anodized billet components
• Complete fuel basket assembly upgrade
• Dual AN6 to main AN8 fuel feed outlets
• High-flow fuel lines and fittings included
• High-flow fuel filter included
• Integrated check valve system
• Full Start/Stop compatibility
• Supports both direct injection and supplemental port injection systems
• RTMG Performance intelligent pump controller included

OEM Brushless Technology Retained

The factory EA888 Gen 4 brushless fuel pump remains fully operational and continues to provide fuel during normal driving conditions through the OEM fuel pump controller.

This preserves:

• OEM cold-start behavior
• Factory fuel pressure control strategies
• Smooth idle quality
• Daily drivability
• Low noise operation
• Start/Stop functionality

The OEM brushless pump is fully compatible with ethanol fuels, making it an excellent foundation for high-performance E85 applications.

Intelligent Secondary Pump Control

The included RTMG Performance Fuel Controller manages the secondary Walbro 450 fuel pump independently from the factory system.

Instead of running both pumps continuously, the secondary pump activates only when additional fuel demand is required under boost.

Benefits

• Reduced fuel temperature
• Lower electrical system load
• Extended pump life
• Improved reliability
• Reduced fuel aeration
• OEM-like operation during daily driving

Pump activation pressure is fully adjustable by the user through the integrated controller and can be configured to activate at the desired boost level, typically around 1–2 bar depending on the application.

Fuel Delivery System Architecture

The upgraded fuel basket features dual high-flow outlets feeding AN8 fuel lines.

Fuel passes through a high-flow check valve assembly, maintaining pressure retention and preserving full OEM Start/Stop operation.

The system then flows through the supplied high-flow fuel filter and forward to the high-pressure fuel pump.

For customers running multi-port injection systems, the kit provides sufficient flow capacity to support additional injectors without compromising fuel delivery to the direct injection system.

Billet Aluminum Construction

All critical mounting components are CNC-machined from aerospace-grade billet aluminum and finished with a hard anodized coating.

Advantages

• Exceptional mechanical strength
• Perfect fitment within the factory fuel basket
• Ethanol-resistant construction
• Superior durability compared to plastic adapters
• Increased reliability under high boost and high G-force conditions

Integrated Fuel Pressure Management

The system incorporates an integrated fuel pressure relief valve within the upper fuel rail assembly.

Standard Configuration

• 6.7 Bar Fuel Pressure

Optional Configuration

• Lower pressure settings available
• Up to +0.5 Bar higher pressure available upon request

This ensures consistent fuel pressure, protects system components, and maintains stable fuel delivery at extreme power levels.
