Which risk increases in a high-performance internal combustion engine encountering crankshaft torsional resonance?

💡 Explanation

When crankshaft torsional resonance occurs, amplified twisting vibrations develop because the engine's firing impulses match a natural frequency, accelerating fatigue crack growth. Therefore, crankshaft failure increases, rather than valve timing issues, bearing wear, or cylinder head overheating, which involve separate issues.
