The test procedures outlined in this SAE Recommended Practice are applicable to single rotor turbochargers having either fixed- or variable- geometry with the following caveat: At this stage in the development of variable-geometry (VG) turbochargers, it would be impractice to generate a detailed practice to cover all types of VG turbochargers which may evolve. However, there is a requirements to quote performance data within a stipulated degree of accuracy and to furnish comprehensive performance information. This will form a basis for this document where further refinements may be added as experience and necessity dictate.
The purpose of this document is to provide a recommended laboratory test procedure and presentation format for establishing the component performance for a turbocharger. It is intended that this test procedure be used to determine turbocharger compressor and turbine performance characteristics.
