Its more of a fluid dynamics situation but whatever.

DCI is very different than scoops. The filter of the DCI is a larger total filtering surface area, where as scoops only "direct" (or so the thought is). Even with a DCI you are "pulling" against the filter surface area, because, again, the way the intake system functions in a turbocharged car is with the exhaust gasses spinning the hot side of the turbo, which then spins the turbine in the cold side of the turbo. The wastegate then regulates how much of that exhaust goes through the hot side and causes the cold side to "suck in."

There is no "forcing air in" into a turbo engine. Period.
