Isolate harmonics before they can destroy your engine.
If you are breaking crankshafts and oil pumps, the cause may be a mystery to you as it has been to many of our customers. We know that 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.
FACT: harmonics CAN destroy these motors despite their ideal 'inline six' balance. Popular word on the street says the OEM units do not fail, but we have dozens of clients who prove otherwise. Some racers would bring a few spare units to each event -not any more. Simply fitting their engines with the VAC damper solved their issue and restored confidence in the powertrain.
ATI Performance Products, a leader in harmonic dampers has developed a VAC exclusive damper for the S50B30 EURO engine.
These VAC exclusive dampers eliminate nearly all unstable crankshaft harmonic vibration which allows the engine to produce more horsepower and torque, maintain reliability and ensure internal engine wear in minimized.
When used with our included VAC Pulley, this is a direct bolt on solution. Available in overdrive, underdrive (for use with standard size pulleys) or standard diameter (for use with under driven accessories, or supercharged cars).
Also, configurations available for use with our dry sump kits. This damper has a 7" outer diameter and it includes OEM style timing alignment tabs.
