Can you put 2 centrifugal superchargers in a car. If so can you put both two one carburetor. or could you have dual carburetors and have a supercharger attached to each one?

Yes, you can install two centrifugal superchargers in a car. You could configure them to feed into a single carburetor or have one supercharger for each carburetor in a dual-carburetor setup. However, careful tuning and engineering are required to ensure proper airflow, fuel delivery, and engine performance, as well as to manage potential complexities in the intake and boost pressure. Always consult with a professional when considering such modifications.
