The SU Carburetors AUSeries, specifically the AU155F and AU155R models, are renowned for their exceptional performance and durability in various applications, particularly in vintage automobiles and high-performance engines. These carburetors are designed to deliver precise fuel mixture for optimal engine performance.
The AU155F and AU155R are 2-barrel carburetors, each having a separate barrel for the primary and secondary throttle bodies. They come with a 520CFM venturi capacity, making them suitable for larger engines requiring more fuel delivery. The carburetors feature a twin choke system, which ensures a consistent and reliable idle and smooth transition during load changes.
The AU155F and AU155R carburetors are mechanically operated, meaning they don't require electricity to function. They are equipped with a reliable vacuum secondary system that utilizes a mechanical accelerator pump and a power venturi. This system ensures a quick response during acceleration and maintains a stable idle at various engine speeds.
The carburetors come with a high-quality, finned, aluminum manifold that offers excellent heat dissipation. The manifold is designed with a flange that can be easily bolted onto the engine, making the installation process straightforward. The AU155F and AU155R carburetors also feature a reliable fuel pump that delivers fuel efficiently to the carburetors.
The exterior of the carburetors is finished with a durable, satin black coating that not only adds to their aesthetic appeal but also protects them from corrosion and wear. The carburetors are also equipped with a breather system that equalizes the pressure between the carburetor and the intake manifold, preventing vacuum leaks.
In summary, the SU Carburetors AU155F and AU155R offer superior fuel delivery and engine performance in vintage and high-performance engines. With a 520CFM venturi capacity, twin choke system, reliable vacuum secondary system, and a high-quality aluminum manifold, these carburetors are an excellent choice for those seeking precision and reliability. Their mechanical operation and durable design make them a long-lasting and worthwhile investment.
