Which outcome occurs transiently when a turbocharged engine's throttle abruptly opens?

💡 Explanation

Compressor surge becomes prevalent because the rapidly increasing airflow demand creates backpressure on the compressor. This exceeds the surge line and leads to flow reversal and instability, therefore surge occurs, rather than a simple pressure decrease if the turbines spooled correctly from the beginning.
