I'm not certain you understand how forced induction works

>>14887353
define displacement

> people who don't realize that more displacement and forced induction are two ways of pumping more air through an engine

But forced induction is a bolt on modification. As in bolted on to an engine of a specific size, or displacement.
>try again faggot

But engines don't work at 100% volumetric efficient so forced induction is just more efficiwncy

Displacement isn't the same thing as mass airflow. Forced induction improves the latter, not the former.

If you want to say forced induction is the same thing as displacement, then so is installing a straight-pipe exhaust, a better flowing intake, more aggressive cams, or anything else that improves the ability of the engine to pump air.

volumetric efficiency=/=fuel efficiency

>>14887467
You can go above 100% volumetric efficiency even without forced induction.

I remember reading about this in auto math handbook, but it only covered carburetor engines iirc and for them, only high output engines get past 100%, when normal engines have like 70 or something.

>>14887511
S2000 can apparently do 110% or so in certain situations. I'm sure other cars can as well.

>>14887511
It's hard (though possible) to do with carburetors for various reasons, but with modern EFI throttle bodies and a high-revving motor it's not that difficult relatively speaking.

I remember there was some built F20C that hit 137% on the dyno. The NA F1 engines were probably doing some pretty obscene VEs as well.

>>14887467
That's not the only effect. The amount of fuel burned is increased as well.

>>14887560
The amount of fuel burned is always increased when you make more power.
