Isolate harmonics before they can destroy your engine.

If your engine build is plagued with broken crankshafts and oil pumps, the cause may be a mystery to you as it has been to many. Controlling the harmonic resonance of the BMW 6 is highly important as RPMs rise, but the ideal configuration of the inline-6 motor makes even experienced engine builders overlook some fundamental principals of engine harmonics that can be destructive.

The truth is, harmonics can destroy these motors despite their ideal balance.
ATI Performance Products, a leader in Harmonic Dampers has developed two new dampers (Part # 917994 & 917994TR) for the popular S54 & S50b32 Euro, as well as the 3 liter S50b30 Euro.

These dampers are made available exclusively through VAC, and they nearly eliminate all unstable crankshaft harmonic-vibration, allowing the engine to produce more horsepower and torque, maintain reliability, and reducing internal engine wear at the same time.

A trigger wheel comes standard on M3 Damper (Part # 917994TR) needed for M3 euro engines.

When used with the included pulley, they allow a direct replacement fit over the OEM balancer. Available in underdriven , overdriven or standard diameters . Also, configurations available for use with our dry sump kits. Both dampers have a 7" outer diameter and include OEM style timing alignment tabs.

• ATI Super Dampers exceed SFI 18.1 Safety Certification and are approved for competition
•Made in USA
•Eliminate problems with inline 6s fitted with lightweight clutch and flywheel assemblies
•Control destructive harmonic forces
•Reduces instances of bearing wear, accessory failure and oil pump failure
•Includes lightweight VAC Billet Crankshaft Pulley (not shown)

Engineered to provide the best compromise between performance and reliability for your BMW.

Specifically designed to underdrive the water pump and power steering pump.
These kits provide 10%-20% overall reduction in driving your car's systems and have been dyno tested to provide up to 12bhp power gain, depending on vehicle.

These pulleys work by reducing parasitic losses from the factory over- driven OEM pulleys, so that more power reaches the rear wheels, as well as providing more throttle response.

We purposefully do NOT underdrive the alternator pulley on road cars as this is not a good idea in our view, however we can do this at specific customer request or for race cars.

PLEASE SPECIFY YOUR ENGINE TYPE / SIZE WHEN ORDERING, THANK YOU .
