Ie carbs before turbos, like on some old skool turbo conversions, renault 5 gordini turbos, etc etc etc.

Do they need a specially modified carb, or is that most the point of them, they dont?

They always seem to use SU's, dunno why, aside from they side draught, so face the right way.

A bit confused how the fuel gets to the engine when not on boost, surely the suck from the engine cant be that good, can it?
