Description
Tilton Engineering Steel Flywheel – BMW M50 / M52 / S50 / S52
Larger diameter. Greater inertia. Smoother power where it counts.
Tilton Engineering’s 12lb steel flywheel is a high-performance upgrade for BMW M50, M52, S50, and S52 engines, engineered with a larger diameter than the OEM flywheel. This added size, combined with its 12-pound mass, provides increased rotational inertia—translating to smoother, more consistent power delivery across the rev range.
Unlike compact 7.25″ race flywheels that prioritize razor-sharp response at the cost of drivability, this larger-diameter unit is built for real-world performance where traction, torque stability, and smooth clutch engagement matter most.
Key Benefits:
- Increased Rotational Inertia
The physically larger diameter helps store more energy during rotation. That means better torque retention, improved idle stability, and less tendency to stall—especially useful in traffic, on inclines, or during launches. - Smoother Power Delivery
The added mass and size help dampen engine pulses and reduce drivetrain shock, making throttle transitions more predictable and easier to modulate. - Drivability Without Sacrificing Performance
At 12 pounds, it’s still lighter than most OEM flywheels but heavy enough to offer smoother clutch engagement and better low-speed behavior than ultralight race flywheels. - Steel Construction for Strength and Longevity
Built to handle high-torque applications without the fatigue risks associated with lightweight aluminum flywheels.
Ideal For:
- Street-driven BMWs with performance upgrades
- Track or drift builds that need low-speed control and launch consistency
- High-torque turbo or supercharged M50 / M52 / S50 / S52 setups
