| It is far more complex than the simplified basis you have suggested. The compressor discharge temperature is dependent on the intlet air temperature of the comrpessor, the ambient pressure of the air entering the compressor, the volume of air entering the compressor, and the pressure ratio at which it is being compressed. To explain what I mean, look at the compressor map:
 The efficiency islands you see on the map reflect what the efficiency of the comrpessor is in terms of how well it can compress "X" amount of air. The higher the efficiency percentage, the lower the temperature of discharge air coming out of the compressor. You are suggesting that by improving the airflow by reducing restrictions, you will also lower the temperature of the compressor discharge, which is only true about half of the time, dependent on what RPM you are looking at. For example: If you reduce the restrictions and improve the airflow of the engine by %5 to a total of 95% volumetric efficiency at 6000RPM and a pressure ratio of 2.8, you are going to reduce the efficiency of the compressor from 74% to about 72%, which is going to RAISE the discharge temperature. -CONVERSELY- If you reduce the restrictions and improve the airflow of the engine by 5% at 5000RPM while running a pressure ratio of 2.3 (18.85psi of boost), you have just moved the engine's airflow into a higher efficiency range, which lowers the discharge temperature. There is far more to this equation than you are accounting for bro - there isn't a simplification to what is trying to be explained here and I hope to have provided some insight to you on the workings of this.
