1. A method for bench-testing a turbocharger using a turbocharger testing system before installing the turbocharger on an engine, the method comprising:
disposing the turbocharger above a lubricating oil tank; and
testing the turbocharger by actuating the turbocharger testing system,
wherein testing the turbocharger further comprises:
engaging a lubrication pump power input to a lubricating oil pump configured to circulate lubricating oil from the lubricating oil tank to a turbocharger lubricating oil inlet, through a turbocharger bearing housing, out a turbocharger lubricating oil outlet, and back to the lubricating oil tank;
allowing the lubricating oil exiting the turbocharger lubricating oil outlet to drain at atmospheric pressure directly into a tank hole disposed on a tank top of the lubricating oil tank;
engaging an air supply device power input to an air supply device;
monitoring, using a computer processor, a set of operational parameters of the turbocharger;
collecting, using the computer processor, a set of data of the set of operational parameters;
disengaging, on or after receiving a signal, the air supply device power input; and
disengaging the lubrication pump power input;
wherein the turbocharger testing system further comprises a monitoring subsystem; and
wherein the monitoring subsystem comprises:
a monitoring of engagement of a lubrication oil pump power input;
a monitoring of a lubrication oil pressure to the turbocharger;
a monitoring of a lubrication oil pump start delay timer; and
a monitoring of a lubrication oil temperature.
