Which outcome occurs when turbine RPM exceeds design thresholds in boosted engines?

💡 Explanation

Compressor surge follows because exceeding designed speed creates a pressure differential against the direction of flow causing flow Reversal – also known as compressor surge — therefore A rather than B, C, or D. The surge reduces boost rather than producing efficient catalysis.
