Holley 1050 CFM Generation 3 Ultra Dominator Carburetor
The Gen 3 Ultra Dominator features a brand new main–body, brand new state–of–the–art calibrations, high volume fuel bowls and sizes up to 1475 CFM! The patent pending GEN 3 main–body is 5/16” taller than the previous generation! This new height allowed for larger radius air entries which were optimized using Computational Fluid Dynamics (CFD) software to deliver smoother flow into new fully machined, big bore venturi. The Gen 3 utilizes high capacity fuel bowls which feature 20% more fuel capacity to eliminate starvation, integrated fuel shelf to minimize fuel aeration and internal baffling to control fuel slosh. Other features include all aluminum construction, 12 hole billet booster inserts, fully tunable billet metering blocks, adjustable external linkage, throttle position sensor mounting points and knurled (hand adjustable) curb idle screws.
