Did he? in what part because I didn't hear it. He must know everyone especially all the OEMs that have much bigger budgets to do all that research and the same guys who designed that lS7 head to work that way and what happens when head porters touch it? It loses all its torque and doesn't work in the lower rpms anymore. But it flows more air.
The fuel has a long way to travel from when it leaves the carb to when you ignite it. Have a think about De-atomization and why he mentions it and then think about OEM stuff and why they do it.
He "said" you want to keep as much "energy" in the port as you can. That Swirl ground into the combustion chamber HAS NOTHING TO DO WITH ENERGY OR LOSS OF ENERGY IN THE PORT.
And everything to do with the energy released at the time of ignition. He's trying to get you to look past just the air component. So why does that LS7 make less power now with more air. What you need to think about is "what" swirl actually does. Stop chasing more air and start chasing a better mixture............one that doesn't De-atomize and burns quickly and efficiently.
Obviously his wet flow bench showed him what the fuel was actually doing in the port and in the chamber and it wasn't what his flow bench was telling him it would do.
