Carburetor sizing for a blow through turbo

Hey all, there is a ton of information on carb sizing, based on your engine size, rpm and HP expectations, but I am wondering if those with experience have advice for carburetor sizing when blowing through a turbo?
Does sizing it for drivability work fine, because the turbo is forcing air through, or do you need to size it for your expected horsepower, or somewhere in between?
Thanks for any advice you can offer!
