ATI damper BMW S54

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.
