im just wondering if Darin or Larry(or anyone else) might have a formula for determining the max flow for a particular valve based on the L/D and test pressure.
there is a chart in the Superflow operators manual that came with my bench when i bought it 12 years ago, but i have to believe that with the way the head technology has evolved in the last 12 years that that chart might be a little outdated.
or, is it more fundemental than that, and the available flow vs area is accurately represented in that chart?
what got me to wondering about it is the differences they show for wedge heads and hemi heads, and i figured the newer design canted valve and high port wedge designs must be getting closer to reaching the potential of the hemi design in this regard(flow vs L/D).
that, coupled with me getting results on some heads where i can slightly exceed the theoretical max flow for certain head and valve combinations has prompted me to ask the question.
when i was reading through one of the posts here where Larry was stating that the newer high port heads can benefit from running cams with higher L/D ratios than the older design, more traditional ports, it got me to thinking about how the new technology might impact the flow potential of the valves themselves.
