Which outcome occurs when the torsional damper fails on high-performance engine crankshafts?

💡 Explanation

When the torsional damper fails, resonance occurs because the crankshaft's natural frequency is excited by combustion pulses, leading to amplified torsional vibrations and high stress concentrations. Therefore harmonic vibrations causing crankshaft fracture result, rather than timing belt slip, oil consumption, or increased exhaust temperatures each based on other independent engine aspects.
