This billet Throttle body is CNC machined from T-6 aluminum in house. This item is built to fit 8 injectors with Ford model injector plugs and has the holley #4150 bolt pattern. This piece has everything that a throttle body should have for example, machined venturis for better flow, roller barring, thick brass butterflies with a diameter of 1.875 that flows 1244 CFM and has been raise 2 inches above the base for more torque, ports for injectors, fuel rail, and will fit the Ford TPS. At this time this is the highest flowing 4150 bolt pattern throttle body in the market.
This piece will fit the jay tech and the Racing Beat intake. This is the answer for all rotary vehicles and hot rods (V-8 needs to add a 1 in. adapter so the air cleaner can clear the fuel rails and some intakes there might be some porting for the 1.875 butterflies) that would like to go fuel injection with minimal fabrications. This a beautiful piece, must see to appreciate.
This throttle body flows 1244 cfm @28 of vacuum. Our bore is 1.870 in diameter. Our butterflies are position 1 3/4 from the base and they sit on 3/8 thick stainless shaft.
