Which consequence results when aggressive engine tuning over-speeds a turbocharger?

💡 Explanation

Compressor surge and failure occurs due to exceeding the turbocharger's design limits. This triggers the mechanism of choked flow, because the compressor physically cannot process any more air. Therefore, surge results, rather than improved efficiency, due to induced backpressure.
