RTMG Performance Upgrade Kit for 1.8 / 2.0 TSI EA888 Gen 3 LPFP - 1150HP Kit Walbro 450 and 525 Aeroflow Filter AN6 Kit HPFP Cap

The most complete kit to upgrade the EA888.3 low-pressure pump!
RTMG Performance is modernizing with new CNC equipment, VSR, dynamometer and, above all, with innovative products.

With this upgrade kit, you can keep your original pump, saving money on buying a new one and on the labor costs you would pay us for installation.

An advantage of upgrading the original pump is that the factory filter, which could be clogged, is replaced by a new, externally installed one.

Introducing the upgraded RTMG Performance fuel pump system, available in four options designed for 900, 950, 1150, and over 1300 horsepower applications.

Incredible help with installation: This kit includes detailed installation instructions, step-by-step with photos, and all the information you need.

900 HP Kit: This kit includes the original VW fuel pump, complemented by an additional Walbro 450 F90000274 pump. It provides a reliable fuel supply to support up to 900 horsepower.

950 HP Kit: The 950 HP kit includes the original factory fuel pump along with an additional Walbro 525 pump, ensuring consistent fuel flow for high-performance needs.

1150 HP Kit: For those seeking ultimate performance, this kit comes equipped with two Walbro pumps: one 450 WALBRO F90000274 and one 525 WALBRO Hellcat, providing exceptional fuel delivery for 1150 HP. This kit also includes a larger diameter fuel line to the high-pressure pump, AN6 fittings, a machined Aeroflow fuel filter, and a high-pressure cap with AN6. The best option for direct installation in racing and motorsport setups.
1300 HP Kit: For those seeking ultimate performance, this kit includes two Walbro pumps: one 450 l/h WALBRO F90000274 and one 525 l/h WALBRO Hellcat, providing exceptional fuel delivery for 1300 HP. In this kit, we use both outlets of the pump cap for increased flow, with an internal supply of 10.5 mm. In addition, it includes a larger diameter fuel line to the high-pressure pump, AN8 fittings, a machined Aeroflow fuel filter, and a high-pressure cap with AN8. The best option for easy installation in a racing environment.

The ultimate solution for fuel delivery issues for MQB platform enthusiasts. Compatible with VW Golf 7, 7.5, Seat Leon, CUPRA Formentor, Audi S3, TT, TTS, and A3 with EA888 Gen 3 engines. The idea arose after numerous tests on our own race cars. Here you will find the information you need about the MQB low-pressure fuel system and the problems our system solves.

The factory system is designed to support up to 400 horsepower, primarily for daily use. However, due to space limitations and VW AG's decision to locate the fuel filter inside the basket along with the pump, there was no room for a pressure regulator. This means that excess fuel does not refill the basket, leading to small pressure drops during hard acceleration, deceleration, and sharp turns when the fuel level in the tank is low.

Our team of engineers, with the goal of improving the system, moved the fuel filter externally to a higher-flow filter and positioned the pressure regulator in such a way that excess fuel always keeps the basket full. The basket essentially acts as a secondary fuel tank, which must always be full.

Furthermore, by moving the filter externally, its replacement and inspection are facilitated, which reduces the cost compared to replacing the entire factory pump due to a clogged filter. This allows the system to operate at its full potential at a much lower cost. Our system retains the factory pump and the low-pressure fuel pump control unit, as it offers high reliability for daily use up to 400 horsepower. However, when greater fuel flow is required for engines exceeding 400 horsepower, the RTMG Performance system provides the solution.

How does it work?

We scanned the basket space with a high-precision 0.02 mm scanner and designed a support structure for both pumps made of forged aluminum, integrating a second WALBRO/TI pump, with a capacity of 450 liters per hour, or even 525 liters per hour depending on use. Thanks to this redesign, we fixed both pumps to the basket with screws, but the most innovative part is that, instead of connecting them with hoses — which creates reliability problems and installation errors — we designed a second forged plate that joins both pumps in a larger outlet. We also positioned the pressure regulator in front of the basket and, for all-wheel drive vehicles, we maintained the transfer system of the second tank.
The second pump is activated by its own circuit, based on boost pressure, and most importantly, it is integrated into the system we designed. The activation of the second pump occurs between 0.7 and 2 bar, and is easily adjusted with an Allen screw on the RTMG Performance control unit. All electrical installation is of excellent quality, with safety measures at all points, capable of supplying 40 amps to the second pump in racing conditions.

No original wiring has been cut, and everything is installed in such a way that, if you decide to sell the car, the system can be returned to the factory configuration with the original pump, exactly as it was before. The installation of our complete system takes no more than an hour, which facilitates the work of mechanics.

The result? A robust, high-quality construction that functions like a factory system, with everything in perfect working order, including the fuel gauge in its original position, supplying your engine with the necessary fuel flow for up to 1000 horsepower and more if required. The complete kit is offered ready to use, but for those who have a factory pump in good condition, we also offer only the upgrade kit.

Thank you for your preference. Welcome to the new generation of performance upgrades.

All kits include the necessary wiring for electrical installation and come with a controller to ensure seamless integration and optimal performance. The unique design of the RTMG adapter allows for a perfect connection between the two fuel pumps, ensuring durability and efficiency.
