It's "atomization" where the fuel droplets are made small enough by flow turbulence so they burn properly.
Tunnel rams really work well from 4000 rpm's and above (like 7000). Since most of the Marine engines top out at around 5800 or so they are not always the best choice.

I done quite a few of these setups and yes...a set of well set up carbs and the engines are dockable and very dependable as well.
