Turbos right out.
Are pro chargers ok? Beside roots what are the options?
Turbos are not allowed on vintage engines, any type of belt driven superchargers are allowed.
Turbo's are not allowed on vintage engines competing in Vintage Body Classes. According to the 2024 rule book. I believe they are allowed in special construction classes.

Desotoman is correct Turbos are only allowed on vintage engines in special construction classes. The same applies for electric injectors as well special construction classes only when used on a vintage engine. If your building a streamliner or lakester with a vintage engine a turbo would be allowed.
