Turbo compressor housing with 2" outlet compared to 2.5" outlet? What gains?

[V6UnderPressure]

Just curiuos how much of a difference you would see if you had the 2" or big boy 2.5" outlet to the intercooler. For sake of discussion, we are assuming an IC inlet pipe of 2.5 or greater.

you mean the difference between the smaller 3" inlet, 2" outlet to the 4" inlet, 2.5" outlet compressor covers?

if that is what you mean it is usually about 10%
