That's pretty cool.  I guess where I would be curious if something along the lines of these "vortex" inserts were in each intake runner.  Maybe it would take the mixture out of the plenum and get it into each valve quicker and with less resistance.  If not, it would at least be fun to see the same Jon Kasse test with these inserted in each intake runner  :0)

Late 80's in a little town in Iowa,I got to see a set of John Force's cylinder heads with vortex generators(wings) in the ports.Very cool !!!

I have put golf ball like dimples in my intake runners and intake ports to help homogenize the A:F but am wary of anything that 'swirls the mixture because there is already going to be some natural swirling by nature and how do you know you are not swirling opposite the natural swirl?--- it seems to me with eight cylinders some will swirl in different directions
