Because everytime that argument is brought up someone with a smaller displacement motor says something to the tune of "Well my turbo makes up for the displacement". Ok well the guy with the bigger displacement can put a turbo on his car too then what happens. There's no replacement for displacement when both cars are equally modded.

You can't put boostfed's car against mine just because I have a V8 and he has a 4 cylinder. He has a built to the fucking brim motor and a turbo for a semi on that bitch.

That was just an example.
