...One of the advantages of EFI is that the effectiveness of the fuelling is decoupled from the air velocity through the throttle body.

not just EFI :-)


Quite true. MFI is the same way, as is CIS (though it moves its intake restriction elsewhere).

Carbs do and must introduce a restriction to work, but it's not usually so bad that it drops top-end power by 30%. That 200-230hp Type I would probably produce just as much power with 48IDAs as it does with the FI, though it may very well need to idle at 2000rpm and fall on its face trying to accelerate from anything below 4000rpm.
