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.

Num motor de quatro cilindros, existem quatro combustões potentes num ciclo completo de 720 graus (duas rotações), correspondentes à entrega de potência do motor. Essas explosões nos pistões, que geram um movimento alternativo, são transformadas em movimento rotativo através do virabrequim, e esse movimento é então transferido para o volante. O volante bi-massa atua como um amortecedor dessas vibrações. Através das suas molas, impede que os picos de força da combustão sejam transmitidos à caixa de velocidades.

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.

Prova do seu sucesso? Conseguimos quebrar o recorde europeu com uma passada de 7,298 segundos usando um motor 2.0L TSI, alcançando quase 309 km/h em Malta Hal Far. Esse feito nos motivou a investir ainda mais neste produto, pois garantiu funcionamento suave sem danos à transmissão, levando-nos a nos tornarmos campeões europeus.

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.

* Sugerido para uso diário e em pista com aplicações de alta pressão de turbo.

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

Este volante foi projetado para virabrequim Toyota e não inclui o adaptador entre motor e câmbio. 

*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*

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