This test document is applicable to all superchargers not requiring fuel to be added to the inlet air prior to the supercharger. This SAE Standard only applies to bench testing. Any maximum speed, temperature, and pressure ratios supplied by the manufacturer should be for this use only and may not apply to applications of firing engines. This document has been adopted by SAE to specify: a. A standard baiss for supercharger efficiency rating; b. reference inlet air supply test conditions; c. a method for correcting observed efficiency to reference conditions; d. a method for presenting these results in an accurate and usable way; and e. a method to compare superchargers without the affects of engine dynamics and intercooling.
Rationale: This document reflects the latest SAE standard format and incorporates numerous updates since the original standard was chartered in 1995. Definitions of measurement techniques and practices have been expanded to permit testing flexibility and to reflect modern testing practices.
