Rick I do not doubt what you say for a minute. You have way more experiance than me. I have mostly read on subjects that interested me.
By theory, as you mentioned, dry air running through the intake will flow more air, and you can polish it up without the problem of fuel dropping out.
All the factory EFI stuff was designed to give cars and trucks good low to midrange torque, and most of the aftermarket was designed with the same goal. I have no doubt this stuff just will not flow well at high rpm.
I think my mass flow system (designed to look like a carb) is rated for 1200 cfm, and it is on a Vic Jr single plane intake. I wonder how well that intake will flow dry air as it was designed for a carb. It would be interesting to see how this EFI compares with a carb.
I do think that in theory the EFI, if designed for power, should do better than a carb every time, but since most EFI systems were designed to lug passenger cars around the streets with good low rpm torque, it just may not be practical to find an EFI system designed for high rpm power. On the other hand, in theory a bumble bee cannot fly, so maybe I'm full of crap.
