The point in a turbine engine where gas pressures are maximized is at the turbine inlet. At this stage, the gases that have been compressed by the engine's compressor are guided into the combustion chamber, where fuel is added and ignited. The combustion of fuel in the combustion chamber significantly increases the temperature and pressure of the gases before they enter the turbine.

During the compression cycle, air is drawn into the compressor, where it is compressed to a higher pressure, which increases its temperature as well. Once the air reaches the combustion chamber, the added heat from burning fuel causes a further increase in pressure. This high-pressure gas then expands through the turbine, driving it and producing mechanical power.

Thus, while the compressor outlet does have high pressure, it is not as high as the pressure found at the turbine inlet, where the energy from combustion elevates both temperature and pressure to maximum levels.
