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.

En un motor TSI o TFSI de cuatro cilindros, se producen cuatro combustiones potentes en un ciclo completo de 720 grados (dos vueltas), que corresponden a la entrega de potencia del motor. Estas explosiones en los pistones, que generan un movimiento alternativo, se transforman en movimiento rotativo a través del cigüeñal, y este movimiento se transmite después al volante de inercia. El volante bimasa actúa como amortiguador de estas vibraciones. Mediante sus muelles, evita que los picos de fuerza de combustión se transmitan a la caja de cambios.

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.

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.

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.

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.

* Suggested for daily and racing use with high boost applications.

Designed and Manufactured in Greece with high technology 5-axis CNC machine.

*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*
