Holley 1150 Cfm 3 Circuit Metering Gen 3 Ultra Dominator Carburetor - Black

In the realm of carburetion, the Dominator® made its mark in 1969, elevating performance to new heights on the NASCAR® circuit. Evolving through the years, the Gen 3 Ultra Dominator represents the pinnacle of innovation, undergoing its most significant transformation yet. A cutting-edge main-body, state-of-the-art calibrations, and voluminous fuel bowls, boasting sizes up to 1475 CFM, define this powerhouse!

The GEN 3 main-body, pending patent, stands 5/16" taller than its predecessor. This heightened design facilitates larger radius air entries, meticulously fine-tuned with Computational Fluid Dynamics (CFD) software for a seamlessly smooth flow into newly machined, big bore venturii. Not just about height, the main-body introduces an integrated idle bypass valve for effortless idle adjustments while maintaining the precise throttle plate to transfer slot relationship. An extended air cleaner flange adds convenience for air scoop attachment with the available air scoop adapter.

Fuel delivery reaches new heights with high-capacity fuel bowls, offering a 20% boost in fuel capacity to eradicate starvation. Integrated fuel shelves minimize fuel aeration, and internal baffling controls fuel slosh. Crafted with all-aluminum construction, the Gen 3 features 12-hole billet booster inserts, fully tunable billet metering blocks, and an adjustable external linkage. Throttle position sensor mounting points and knurled (hand-adjustable) curb idle screws add to the versatility.

Each calibration undergoes rigorous dyno and track testing for proven performance! Features:
