They both explained it to cause turbulence
don't recall saying that?
I do recall something to the effect of saying its an attempt to convert turbulent flow to laminar flow prior to transition up the boost and transfers and effect desired tumble and swirl in the combustion chamber.
Theres alot of ways to skin a cat. best of luck, it certainly is novel anyway.
You might want to consider port velocity based on volumetric increase in the transfer port and its effect on charge speed and atomization effeciency. Unfortunatly air does not scale well like most people think it does.
also the theory of Min R = Dia X 2 when trying to affect flow rate.
you might find this usefull.
More power: yes it is surely possible
Longer run times: It takes fuel to make power and unless you have created a way to defy airfuel theory it is unlikley, as you have created higher total flow through the engine, assuming your carburetor is still of standard conventional design. It highly depends on the test conditions and throttle percentage open, needle settings, and temp over a measured test to be able to make a quantifiable claim such as that. We call it VE and BSFC
don't take that the wrong way it is just an opinion given a bunch of years doing engine development for General Motors corp.
