in your case, i think the air flow should be

air filter + TB > Supercharger > intercooler > manifold.

you can have weber supercharged engine. there are two methods: blowthrough and drawthrough. in drawthrough, the airflow is carb > sc > manifold. using this setup, you can't use an intercooler. the fuel will condense in the intercooler. plus point for this setup, it's easier to set it up right.

another method is blowthrough. sc > carb > manifold. while this is harder to do, they have their own plus point. it is harder because you have to completely seal your carb in boost, your fuel pressure should conform with the boost. but you can use your intercooler for better knock resistance.
