you do realize that there is a lot more to turbo efficiency than " move more air through a bigger tube", correct?Get any size bucket you want to it doesn't matter. Get a bigger diameter hose to fill it then you will see how and what fills up faster.
for forced induction, in particular turbos, you need to pick up CFM AND velocity.
your example would only be picking up CFM.
The pump needs to create MORE pressure to maintain velocity when the "hose" gets larger. ( or you need a bigger pump)
If it doesn't, you'll actually lose power.
Most modern turbos need a specific backpressure target to maintain efficiency.
