Port Flow Analyzer now available from SuperFlow Technologies Group is a computer software program designed to streamline recording, calculating, reporting and graphing of cylinder head fl owbench data ? while using the latest technology to make fl ow testing faster, easier, more accurate and more professional. Port Flow Analyzer enables engine builders and engineers to compare head/cam/engine combinations for peak performance, allowing them to create "cutting edge" improvements in cylinder head flow, port velocity, swirl and tumble motion. Also included are special features that save valuable time (in repetitive data entry) and partially completed selection guides that help speed the process of choosing lift, flow range and test pressure settings. The Port Flow Analyzer (Pro Version) also has options for port velocity mapping with a pitot tube, swirl and tumble measurement, port stability, and more.
