Our Port Flow Analyzer for flow bench testing has several features for making several measurements of cylinder head performance.  For head flow, pretty much anything that improves CFM flow improves the HP potential of the head. But after measuring CFM, there are several other measurements which can give better insight into one particular head runs well on the dyno or the track, and another head with equal or sometimes even less flow can run much stronger. These are the hard earned “black arts” of head porting which many engine builders are reluctant to share. Questions these engine builders are looking to answer include: Read the rest of this entry »
