What is Limiting Your Engine Air Flow:Using Normalized Steady Air Flow Bench Data

Data from steady air-flow bench tests are made more useful during engine design and development when they are normalized for critical geometric parameters. The procedure is illustrated in the study described here. Using prescribed test and data reduction methods, steady air-flow data were collected from a broad spectrum of high performance race engines. The resulting database then offered a benchmark against which a new engine was evaluated, and directions for future development were made clear.
