What is a Turbo CHRA?

A complete turbocharger is essentially a Centre Housing Rotating Assembly (CHRA or core assembly) with housings fitted to

each side. The turbine housing directs exhaust gas to power the turbine wheel, the compressor housing directs air into the

engine. The turbine housing will have a wastegate to control the turbine speed, or as is more common on diesel engines, there

is a variable vane mechanism giving much better control of the turbo, reducing lag, and improving performance. The wastegate

or vane mechanism is controlled by an actuator – which could be controlled either electronically or by a vacuum system.

The CHRA is a rotor (turbine wheel on one side, compressor wheel on the other) that is held in a bearing system allowing it to

rotate at high speed on a pressurized oil film similar to the engine. Turbo remanufacturer’s traditionally stripped the complete

turbocharger and CHRA, examine all the individual components, replacing these where necessary, and install brand new

bearings and seals.
