PRODUCT DESCRIPTION
The ultimate solution for fuel supply issues for Audi, VW, Seat, and Skoda enthusiasts. Compatible with 2.0L TFSI EA113 S3, A3, GOLF5, GOLF6, SEAT LEON, SKODA OCTAVIA, TTS, TT, and SCIROCCO. The idea emerged after numerous tests on our own race cars. Here you will find all the information about the 2.0L TFSI low-pressure fuel system and the problems our system solves.
The factory system is designed to support up to 430 horsepower, primarily for daily use.
How does it work?
We scanned the tank space with a high-precision 0.02mm scanner and designed a support structure for both pumps, made of forged aluminum, which integrates a second WALBRO/TI pump, capable of 450 liters per hour. Through this redesign, we secured both pumps to the basket with screws.
The second pump is activated by its own circuit, depending on the boost pressure, and most importantly, it is integrated into the system we designed. The activation of the second pump occurs between 1.2 and 2 bars, easily adjustable with an Allen screw on the RTMG Performance control unit. All electrical wiring is of excellent quality, with safety measures at all points, capable of supplying 40 amps to the second pump under racing conditions.
Nothing from the original wiring is cut, and everything is installed in such a way that, if you decide to sell the car, the system can be reverted to the factory configuration with the original pump, just as it was before. The installation of our complete system takes no more than an hour, which makes the mechanics' job easier.
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 with a good factory pump, we also offer just 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 exclusive design of the RTMG adapter allows for a perfect connection between the two fuel pumps, ensuring durability and efficiency.
