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.

Il nuovo design flottante impedisce alle molle di entrare in contatto con le masse in movimento, garantendo un funzionamento fluido e una maggiore durata del gruppo. Per chi cerca le massime prestazioni, ogni componente è bilanciato dinamicamente a 0,01 g e il peso complessivo è inferiore del 20% rispetto al volano originale. Inoltre, i componenti interni in Teflon rendono il nostro volano bimassa più stabile agli alti regimi, prevenendo risonanze e vibrazioni laterali.

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.

Progettato e prodotto in Grecia con macchine CNC a 5 assi ad alta tecnologia.

*Per un corretto accoppiamento sull’albero motore, e poiché la guida dell’albero è spesso usurata, il volano è realizzato con un foro leggermente più piccolo (0,02 mm). Potrebbe essere necessaria una leggera carteggiatura con carta abrasiva per ottenere un accoppiamento perfetto. L’esatto accoppiamento tra volano e albero motore è fondamentale agli alti regimi, perché garantisce il perfetto bilanciamento dell’intero gruppo*

* Consigliato per uso quotidiano e pista con applicazioni ad alta pressione di sovralimentazione.
