Abstract: A process for monitoring turbocharger operation in a machine is disclosed. The machine includes a power source having an intake manifold for supplying the power source with air and a plurality of turbochargers. Each turbocharger includes an air inlet passageway to receive air, a plurality of pressure sensors arranged within the inlet passageway, a compressor configured to pressurize air, an air outlet passageway to direct pressurized air from the compressor to the intake manifold, and an exhaust turbine operably driven by exhaust gas from the power source and coupled to the compressor by a turbine shaft. The process includes monitoring the differential pressure across the air inlet passageway for each turbocharger, comparing the differential pressures for each turbocharger and indicating an anomaly in turbocharger speed when the differential pressure for one turbocharger exceeds the differential pressure for another turbocharger by a threshold amount.
