I said it earlier but if you make the area around the valve bigger just because it flows more you are killing power. Just because the flow bench says more air flow doesn’t make it better.
Flow benches are just tools. They try to replicate a characteristic of a running motor...but don't accurately simulate a running motor.
Just a thought i have is when you negatively alter the fuel distribution around the valve, or have a biased port... that burn time and efficiency takes a hit.
But be more specific. Is it chamber to bore or chamber to valve. Tossing statements like "just because it flows more air doesn't mean it makes more power" Who should toss their heads in the trash and why..?
And lets talk about flow setup on the bench and the effect of bore center and placement of the shrouded side of the bore lining up. Throw in the importance of an intake manifold straight wall lining up perfect with the port straight wall on power and the reflected flow increase on both the bench and the dyno, volume, discharge etc..
In what example are you using to it's relevancy?
Dissect it more and explain what you are trying to say to these people.
