Though not stated, I'm gonna assume the "b" numbers are from your bench Dwayne.
Correct...... my numbers are bench B.
I’ve tested several heads that come CNC ported from the manufacturer, where they have published flow numbers.
Sometimes the flow numbers from my bench are pretty close from top to bottom.
Other times........ close for some of the curve.....not all that close for other parts of the curve.
Once in a while, my numbers will be a little higher than the advertised numbers......... although that doesn’t happen very often.
I’m on my second bench.
I bought the first one at the end of 1992, and the current one in August 2007.
As for the phrase, “racing flow benches”, it’s something I say to people/customers who are trying to compare numbers they have gleaned from different sources, off different benches.
I tell them......... you’re just “racing flow benches”.
Same situation as “racing dynos”.
