A method of operating a gas turbine engine includes providing combustion gases to turbine means, and choking flow of the combustion gases for increasing shaft horsepower in an output shaft while reducing thermal efficiency of the gas turbine engine. The method may also include the step of supercharging the turbine means for further increasing output shaft horsepower. In accordance with an exemplary embodiment, a gas turbine engine effective for carrying out the method is disclosed. The engine includes an output shaft, compression means, combustion means, turbine means, and diffusion means for diffusing combustion gases discharged from the turbine means for obtaining choked flow for increasing shaft horsepower and reducing thermal efficiency. The compression means is effective for supercharging the turbine means at a predetermined speed of the output shaft for providing increased output shaft horsepower.
