Is More Flow Better, Is The Smallest Intake Port That Flows The Most The Best
Target velocity ... know the territory.
Totally agree. Have a think about what creates the demand for air to flow in the first place ie the piston speed and where the valve is in relation to that and also the vacuum generated at the valve curtain area and how that aids vaporization because liquids don't burn in cylinders gasses do. Funny how head porters never talk about combustion and how to improve it because all they understand is airflow. When you can't utilize the fuel and air you already give an engine give it more air........
I've posted many examples of engines that punch above their weight for the head size and airflow those engines receive. Imagine a 360 running to 6K with a 1.78 valve. As always you can highlight facts but people will always attack what they don't understand.
Have no idea, what's the significance ?
Is the cylinder still filling as the piston passes BDC and returns to TDC? Does that column of air and fuel have inertia and does it still continue to fill the cylinder until the valve closes?
All these things you need to think about if you want to build power. Here's a thought what happens with you put a much bigger head with a much bigger valve and a big manifold and a big carb on that same piston speed and demand generated? Ever thought about that?
Vacuum plays a big part in vaporizing the fuel so you can burn it so does all that increase in size help that or worsen that? Does the distillation temp of the fuel you use matter?
Now go and look at this engine and think about how the smaller carb ran the quickest, Idled the leanest while making 4.5 inches of vacuum at the top end.

There's more to making power than just airflow other wise the bigger carbs would have run quicker. Head Porters always talk about the air they never discuss the fuel.
