The first problem with resonance in the crankshaft will be erratic main bearing wear which we believe is the case in the VR38, stronger resonance can also lead to crankshaft failure in the long term(which we don’t expect to see in the VR38). The issue is caused by factory engine dampers tuned for the stock power level and in the VR38s case, likely the same part seen on the VQ35 to begin with. The Boost Logic damper is designed to work across a broader range of engine power levels and modifications. It utilizes a larger higher quality damper ring than factory so it is better suited to balance out the stronger resonance created by engines that produce higher torque levels than factory.
