Read a thread on another Forum about how those CNC shocker heads can be 20 CFM shy of what's advertised =285 cfm -20=265cfm
Which should not be a surprise, variance that is in reproducing that or should I say duplicating that same CNC on different ports that shifted differently
I when I read these things, I can only wonder at what bore size the company flowed them at and what the purchaser did and how he did. 20 cfm is a major discrepancy.
