I don't have any experience turbocharging bikes, but I do have a 69 Camaro that I turbocharged. It is carburated, and the boost is blown through the carburetor as described with the turbo f3. To run a carburetor in a boosted application, some changes have to be made. The brass floats that are in most car carburetors tend to crush from the boost pressure at about 5 psi, so you have to put solid nitrophyl floats in it. You can jet up the carburetor to add the extra fuel, but then it runs rich when you're not in boost. Since a car carb is usually a progressive 4-barrel, you can just make the secondary jets bigger, since you won't be making boost just riding around. Car carbs also have a power valve, which normally opens when there isn't much vacum on the motor (when you mash the gas hard). You can also modify that valve to only open under boost pressure. Fuel injection is easier,but alsomore expensive. It is quite possible to run a carb with boost.

If anyone is serious about wanting to run a turbo with carbs, the should check out the following link. It's the best site on the net for turbocharging anything. They have a carb-specific forum as well.
