Well, actually it was a similar system to Fw 190C. As far as I know, every P&W R-2800 made also had an internal supercharger mounted directly behind the engine, driven by the crankshaft. The confusing thing here is, that while the air from turbocharger went indeed to the carburetor, from there it continued to the supercharger! After that, it's of course going to cylinders. Some pictures to clarify:
P-47 Engine, supercharger in blue colour, carburetor is the black thing on top of it:
Another view, showing the duct leading to carb, blue object is the supercharger:
Rolls Royce Merlin had almost the same setup (I think most WW2 engines did), except it had an liquid cooled intercooler as the last thing before the intake. Also of note here (two stage version) is that the air is cooled between the stages too!
Hope this helps, I get sometimes confused with this technology too.
