CNC Sport Dual-Mass Flywheel with Upgrade Cover – for VW R32 DQ500 10-Bolt

CNC Sport Dual-Mass Flywheel for VW R32 Engines with DQ500 – 10-Bolt, PTB Racing Upgrade Cover

The PTB Racing CNC Sport Dual-Mass Flywheel with Upgrade Cover was specifically developed for high-performance applications using VW R32 engines with the DQ500 DSG transmission. This version combines the 10-bolt flywheel with the PTB Racing Upgrade Cover and its significantly larger spline connection.

The larger spline was developed for applications with increased drivetrain loads. The dedicated connection design also eliminates the critical positioning of mounting holes directly behind the spline area.

The flywheel itself is a completely new PTB Racing development manufactured from new components. It is not a modified or reworked dual-mass flywheel. Increased damping force, reduced weight and optimized mass distribution combine high-performance capability with effective torsional vibration damping and reduced transmission noise.

The system is already in use in vehicles producing up to 1,420 hp.

CNC Sport Dual-Mass Flywheel for VW R32 with DQ500

The CNC Sport Dual-Mass Flywheel combines torsional vibration damping, drivability and increased continuous-load capability in a system developed specifically for high-performance DQ500 applications.

Its increased damping force reduces the transfer of torsional vibrations from the engine into the transmission. This helps reduce drivetrain excitation and transmission noise compared with a rigid single-mass flywheel setup.

Normal street driving remains possible while retaining the increased load capability required for high-performance street, track, drag racing and motorsport applications.

Vehicles producing up to 1,420 hp are already running this CNC Sport Dual-Mass Flywheel. This figure represents proven real-world use and is not a general power rating for every vehicle configuration. Actual loads depend on torque, engine setup, drivetrain configuration and operating conditions.

PTB Racing Upgrade Cover with Larger Spline Connection

This version uses the PTB Racing Upgrade Cover with a significantly larger spline connection.

The larger spline provides a robust positive-locking interface for transmitting drivetrain loads. At the same time, the dedicated design eliminates the critical arrangement of mounting holes directly behind the spline area.

The connection between the CNC Sport Dual-Mass Flywheel and Upgrade Cover is form-fitting, with torque transmitted through the spline connection. The drive adapter is additionally secured with a retaining pin.

The PTB Racing-developed connection design is protected.

For vehicles already equipped with a compatible cover using the standard connection, a separate version of the CNC Sport Dual-Mass Flywheel is available.

Completely New PTB Racing Development

The PTB Racing CNC Sport Dual-Mass Flywheel is manufactured entirely from new components. No existing or used dual-mass flywheels are modified or reworked.

It was developed specifically for applications requiring increased continuous-load capability while retaining effective torsional vibration damping and normal drivability.

A patent application has been filed for the PTB Racing dual-mass flywheel technology.

Standard or Upgrade Bolts with Precision Shoulder

Two bolt configurations are available:

Standard Bolts
The standard version uses the intended conventional bolted connection.

PTB Racing Upgrade Bolts with Precision Shoulder
For highly loaded applications, PTB Racing Upgrade Bolts with a precision shoulder are available. The shoulder provides defined positioning within the mounting holes and prevents relative movement caused by clearance between the bolt and bore.

This provides more precise positioning of the connection under increased mechanical loads.

Diamond Friction Washer

A diamond friction washer is always included with the system.

The diamond friction washer increases friction within the bolted joint and supports reliable load transfer through the connection.

Approx. 9 kg – Reduced Weight and Optimized Mass Distribution

The PTB Racing CNC Sport Dual-Mass Flywheel weighs approximately 9 kg / 19.8 lbs, making it lighter than the standard flywheel.

In addition to the reduced overall weight, the mass distribution has been optimized. A greater proportion of the rotating mass is positioned closer to the center of rotation, reducing the mass moment of inertia while retaining the damping characteristics of a dual-mass flywheel.

This combines reduced rotating mass and optimized inertia with the torsional vibration damping required for a high-performance drivetrain.

Increased Damping Force and Reduced Transmission Noise

Increased damping force is a key characteristic of the PTB Racing CNC Sport Dual-Mass Flywheel.

Engine torsional vibrations are damped before being transferred into the DQ500 transmission. This helps reduce transmission noise while retaining the advantages of a dual-mass flywheel in a significantly higher-performance application.

The combination of increased damping force, torsional vibration damping and increased continuous-load capability allows normal street driving while supporting demanding high-performance applications.

Noise and Usage Information

The CNC Sport Dual-Mass Flywheel is specifically designed to reduce torsional vibrations and resulting transmission noise.

Depending on engine calibration, idle speed, transmission software and the overall vehicle configuration, additional mechanical or transmission noises may still occur. Complete elimination of drivetrain noise cannot be guaranteed in high-performance applications.

Development, Quality and Manufacturing

The CNC Sport Dual-Mass Flywheel and Upgrade Cover system is a dedicated PTB Racing development for high-performance clutch and drivetrain applications.

The flywheel system is precision manufactured from new components and fine-balanced for smooth operation.

Engineered in Germany. Assembled in USA.
