Re: FLOW Bench / Optimum Valve Lift
Well, dry flow air is completely different than what should be done, a metered air/liquid wet mixture flow bench.
I built mine over a decade ago, keep updating it, and get real world results. I also have a very nice dry flow bench, so I get both results from a project.
Dry flow is OK, I guess, but the heads I have done after dry flow, on my wet flow worked a lot better.
Just my take on flow benches.
Always remember one thing about custom head porters that live by the flow bench, you get the head that had a reduction in flow efficiency just after the best reading.
