Which risk increases when an internal combustion engine turbocharger overspools beyond design limits?

💡 Explanation

When a turbocharger overspools, compressor surge can occur, because rapid pressure fluctuations build on the compressor face reducing mass airflow leading to instability. Therefore, compressor surge results, rather than bearing, knock, or fuel dilution, which are caused by independent mechanical/chemical issues.
