1. A method of controlling airflow of an engine system, comprising:

  • determining a supercharger operating mode of a supercharger and a turbocharger operating mode of a turbocharger based on engine load of the engine system;

    selectively generating a control signal to control a turbine of the turbocharger to adjust a compression of air by a compressor based on the turbocharger operating mode; and

    selectively generating a control signal to control a supercharger bypass valve based on the supercharger operating mode, the supercharger bypass valve disposed between the turbocharger and the supercharger in the engine system;

    wherein controlling the turbine of the turbocharger permits the compression of air by the compressor of the turbocharger as a function of at least one of an engine airflow requirement and a pressure requirement when the turbocharger operating mode is a closed loop mode; and

    wherein controlling the turbine of the turbocharger restricts the compression of air by the compressor of the turbocharger as a function of engine load and engine speed when the turbocharger operating mode is an open loop mode.
