Turbochargers can operate at speeds of over 200 000 RPM, driven by exhaust gasses of over 950 °C. At these speeds the compressor and turbine blade tips approach the speed of sound and even the smallest object entering the turbocharger inlets can cause extensive damage.
Causes of foreign object damage to the compressor.
Sections of a damaged or blocked air filter sucked into the compressor intake.
No air filter fitted. This allows objects to enter the air inlet system.
Gasket material entering the air intake. Only the correct gaskets should be used when fitting a turbocharger. The use of liquid/silicon sealers will void the turbocharger warranty.
Loose bolts, nuts, washers or other items left in the air intake pipe during servicing.
Causes of foreign object damage to the turbine
Gasket material entering the exhaust intake. Only the correct gaskets should be used when fitting a turbocharger. The use of silicon/ fire gum sealers will void the turbocharger warranty.
Broken engine components such as injector tips, valves or other debris caused by an engine failure.
Preventing foreign object damage to the turbocharger
Always fit the correct gaskets when fitting a turbocharger. The use of any sealers such as silicon and fire gum can damage the turbocharger and will void the warranty.
Ensure that all hoses, pipes and connectors are in good condition and free of any obstruction or lose objects.
Always fit the correct air filter to ensure an unrestricted flow of particle free air.
Ensure all air hoses are in good condition and free from blockages or foreign items.
Before fitting a turbo check for left over turbocharger or engine fragments from the previous turbocharger failure.
