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 five-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 DQ500 gearboxes to handle up to 750Nm of torque for daily use.

But what happens beyond that? When the torque exceeds 750Nm, 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.

Como entusiastas del rendimiento y tras haber sufrido repetidos problemas con las transmisiones DQ250 en nuestro propio coche de carreras 2.0 TFSI, decidimos encontrar una solución. La mentalidad de nuestros ingenieros es diseñar algo que mejore el rendimiento con mejores mecanismos y materiales. En el nuevo volante de inercia que diseñamos, fijamos el listón muy alto en términos de calidad, durabilidad y vida útil, permitiéndole soportar de 770 Nm a 1200 Nm de par. Se probó y desarrolló en nuestro propio coche de carreras.

Proof of its success? We managed to break the European record with a 7.49-second run using a 2.0L TSI engine, reaching nearly 310 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.
