Holley 1150 Cfm Dominator Sp Carburetor - 3-Circuit

Holley engineers have developed a cost-effective iteration of the cutting-edge Gen 3 Ultra carburetors, tailored for street/strip applications and high-performance bracket or sportsman drag cars. The new Holley SP Dominator carburetors showcase the patent-pending Gen 3 main-body, boasting a 5/16" increase in height compared to the previous generation. This heightened design facilitates larger radius air entries, ensuring smoother flow for improved throttle response and consistency. An extended air cleaner flange is seamlessly incorporated for easy air scoop attachment when using the available air scoop adapter. Other features encompass all-aluminum construction, adjustable billet metering blocks, throttle position sensor mounting points, and knurled (hand-adjustable) curb idle screws. Each calibration undergoes rigorous dyno and track testing to ensure proven performance!
