Turbo
Turbo OverspeedingWhy does overspeeding damage turbos? Turbochargers can operate at speeds in excess of 200,000 rpm, with exhaust gases around 800°C. Each turbo is designed and manufactured to rotate at the correct speed for its application. Overspeeding is when the turbo rotates at a greater speed than its operational limits. Overspeeding can push the turbo beyond its safe operating parameters, causing it to fail by damaging the turbine or compressor wheels and bearings. If the turbo continues to overspeed, it can overboost the engine, resulting in serious damage to the internal components and potentially complete engine failure. What causes overspeeding?
Compressor destroyed by overspeeding.
'Orange peel' effect on backface.
Turbine blade fracture.
