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.

Mais que se passe-t-il au-delà ? Lorsque le couple dépasse 420 Nm, les ressorts à l’intérieur du volant moteur d’origine atteignent leur limite, et les forces de combustion au-delà de ce point martèlent toute la transmission – du vilebrequin et de ses boulons jusqu’aux engrenages, aux arbres de transmission et finalement aux pneus. Le volant moteur d’origine n’a pas été conçu pour supporter des configurations à turbo hybride ou gros turbo, des pneus slick pour les départs arrêtés ou 10 000 tr/min.

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.

The new floating design prevents the springs from contacting the moving masses, ensuring smooth operation and longer lifespan of the assembly. For those seeking ultimate performance, every component is dynamically balanced to 0.01G, and the overall weight is 20% lighter than the factory flywheel. Additionally, the internal Teflon components make our dual-mass flywheel more stable at high RPMs, preventing resonances and lateral vibrations.

Un avantage très important supplémentaire de notre volant moteur renforcé est que, comme les ressorts renforcés ne se compriment pas totalement sous des couples plus élevés par rapport aux ressorts d’origine, il empêche la rupture des vis entre le volant moteur et le vilebrequin, car toutes les forces d’impact sont absorbées par les ressorts renforcés. Les ressorts fonctionnent dans un environnement lubrifié, garantissant que l’ensemble fonctionne harmonieusement lors des phases d’accélération et de décélération, aussi bien en conditions de course qu’en usage quotidien.

For a proper fit on the crankshaft, and because the crankshaft guide is often worn, the flywheel comes with a slightly smaller hole (0.02mm). It may require slight sanding with sandpaper to achieve a perfect fit. The precise fit between the flywheel and crankshaft is crucial at high RPMs, as it ensures perfect balancing of the entire assembly.

ATTENTION: ITS ALREADY BALANCED WITH ADVANCED BALANCING METHOD, PLEASE NOT TRY TO BALANCE THE FLYWHEEL AND REMOVE MATERIAL !!!
