Worse combustion chamber design ever? Saveable?

In some cases.

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.


You can talk about it. I’m not typing all that out.

I simply stated you can keep moving the chamber wall out and it will flow more air. You kill pressure recovery when you do that.

The valve job has an influence on pressure recovery (exit loss) too.

Like an exhaust port, using a flow bench, particularly using mass air flow through the flow bench to determine chamber shape is not always the way to do it. Not all air flow is good air flow. The exhaust port is a perfect example of that. Make it as small, fast and quiet as you can and it will flow less and make more power.
