Presentation and Benefits of the RTMG PERFORMANCE Dual-Mass Flywheel

Another innovation in DSG automatic transmission systems from RTMG PERFORMANCE. The benefits of a dual-mass flywheel compared to the previous generation single-mass flywheels are significant. The importance of having two masses in the flywheel lies in smoothing out the explosions created by the combustion of the pistons during the third stroke of ignition.

In a four-cylinder TSI or TFSI engine, there are four powerful combustions in a full cycle of 720 degrees (two rotations), corresponding to the engine's power output. These piston explosions, which generate a reciprocating motion, are transformed into rotational motion through the crankshaft, and this motion is then transferred to the flywheel. The dual-mass flywheel acts as a damper for these vibrations. Through its springs, it prevents the peak combustion forces from being transmitted to the gearbox.

By smoothing out these forces, smooth power transmission from the engine to the gearbox is achieved, leading to longer component life and preventing the gears from wearing out. The manufacturer designed the dual-mass flywheel for the DQ250 gearboxes to handle up to 420Nm of torque for daily use.

But what happens beyond that? When the torque exceeds 420Nm, the springs inside the factory flywheel reach their limit, and the combustion forces beyond this point hammer the entire drivetrain—from the crankshaft and bolts to the gears, axles, and finally to the tires. The factory flywheel was not designed to handle hybrid or big turbo setups, slick tires for launches, or 10,000 RPM.

As enthusiasts of vehicle performance and having experienced repeated issues with the DQ250 transmissions in our own 2.0 TFSI race car, we decided to find a solution. Our engineers’ mindset is to design something that enhances performance with better mechanisms and materials. In the new flywheel we designed, we set the bar high in terms of quality, durability, and longevity, allowing it to handle from 770Nm to 1200Nm of torque. It was tested and developed in our own race car.

Proof of its success? We managed to break the European record with a 7.8-second run using a 2.0L TSI engine, reaching nearly 300 km/h at Santa Pod Raceway in England in 2022. This achievement motivated us to further invest in this product, as it ensured smooth operation without damage to the transmission, leading us to become European champions.

Our latest version is made of high-strength chromoly steel (42CrMo4), and the splines undergo thermal treatment for maximum durability. The springs are twice as strong as the factory ones, but the key improvement is the progressive spring design. The initial springs are softer, allowing the flywheel to operate smoothly at lower loads. Another advantage over the factory flywheel is that ours is modular, meaning it can be serviced or upgraded for even more torque if needed.

Das neue schwimmend gelagerte Design verhindert, dass die Federn mit den beweglichen Massen in Kontakt kommen, was einen ruhigen Lauf und eine längere Lebensdauer der Baugruppe gewährleistet. Für alle, die maximale Performance suchen, wird jedes Bauteil dynamisch bis 0,01 G ausgewuchtet, und das Gesamtgewicht ist 20 % geringer als beim serienmäßigen Schwungrad. Zusätzlich sorgen die internen Teflon-Komponenten dafür, dass unser Zweimassenschwungrad bei hohen Drehzahlen stabiler ist, Resonanzen verhindert und seitliche Vibrationen reduziert.

Another very important advantage of our reinforced flywheel is that, since the reinforced springs do not fully compress under higher torques compared to the factory ones, it prevents the bolts between the flywheel and the crankshaft from breaking, as all the impact forces are absorbed by the reinforced springs. The springs operate in a lubricated environment, ensuring that the entire assembly works harmoniously during accelerations and decelerations, whether in racing conditions or daily use.

Welcome to the next generation of performance products by RTMG PERFORMANCE.

It has harder springs than the factory receiving more torque helping the transmission system in extreme conditions.

It is divisible helping to maintain it over time.

Dynamic balance 0.01g can performance the maximum horsepower at high rpm.

Entwickelt und hergestellt in Griechenland mit hochmoderner 5-Achs-CNC-Maschine.

*Für einen korrekten Sitz auf der Kurbelwelle – und da die Kurbelwellenführung häufig verschlissen ist – wird das Schwungrad mit einer etwas kleineren Bohrung (0,02 mm) geliefert. Es kann ein leichtes Nachschleifen mit Schleifpapier erforderlich sein, um eine perfekte Passung zu erreichen. Die präzise Verbindung zwischen Schwungrad und Kurbelwelle ist bei hohen Drehzahlen entscheidend, da sie eine perfekte Auswuchtung der gesamten Einheit sicherstellt.*

* Empfohlen für den täglichen Einsatz und Rennbetrieb mit hohen Ladedrücken.
