GT6/175CD Manifold Kit
The triple Stromberg or SU carburetor system has grown steadily in popularity since I introduced it in 1991. More and more TR6 owners are realizing how well it performs, offering the high performance they want without a sacrifice in fuel economy or street manners. I've had great success using this system on high performance TR6 engines I've built and I received excellent reports from customers who installed the kit on their engines. Strombergs and SU carburetors have a sliding air valve creating a variable venturi to maintain high air velocity across the jet regardless of the volume of airflow. At idle when the engine is using very little air the air valve is only open a crack so the air still rushes past the jet to properly mix the fuel. As the throttle is opened and the load on the engine is increased the air valve rises, riding on the airflow to maintain velocity. At full throttle under load the air valves are fully open exposing a wide-open passage for air. This performance simply cannot be matched by a fixed venturi carburetor. If a fixed venturi is sized large enough to provide adequate flow at high rpm it will not mix the fuel properly at low rpm resulting in poor fuel economy. With triple Stromberg or SU carburetors the fuel mileage is generally in the mid 20's and the performance is fantastic with instant acceleration and smooth power throughout the rpm range. Installation is easy, original Stromberg carburetors require no modifications, simply add an additional carburetor and a Good Parts triple intake manifold kit. The SU carburetors are specially configured to work on a Good Parts triple intake manifold and the entire assembly bolts right on. This system is a worthwhile improvement to a stock engine and provides even greater benefit to a modified engine.
Order the triple manifold kit for use with your own Stromberg carburetors or as a complete, ready to bolt on assembly with brand new SU HS6’s. Complete manifold and carburetor assemblies include all new accelerator linkage to connect to the lever at the firewall. Stainless steel fuel line assemblies are available configured for the fuel supply line coming around the front of the engine as supplied from the factory or for fuel supply from the rear of the engine. Triple stranded choke cables are also available.
