Tunnel Ram

Carburetors

Good tunnel ram carburetors have special requirements.  Chuck Nuytten is very experienced in using multiple carburetors on tunnel ram applications.  Air flow and booster signals of each carburetor venturi must match to perform as a team.  Our tunnel ram carburetors utilize custom circuitry for the best response and power.  Chuck Nuytten tunnel ram carburetors also have matched linkages and special accelerator pump geometry.
