Crankshaft resonance shows up first as erratic main bearing wear, which we believe is the case in the VR38. Stronger resonance can also lead to crankshaft failure over the long term. The issue is caused by factory engine dampers tuned for the stock power level — in the VR38's case, likely the same part seen on the VQ35.
The Boost Logic damper is designed to work across a broader range of engine power levels and modifications. It uses a larger, higher quality damper ring than factory, so it is better suited to balancing out the stronger resonance created by engines producing higher torque levels than stock.
