The Holley Gen 3 Ultra Dominator Carburetor #0-80906HB – 1150 CFM is the next evolution of Holley’s legendary race carburetor, originally launched in 1969 for NASCAR®. Redesigned with a taller 5/16” main body, advanced airflow technology, and precision calibrations, it delivers the performance today’s high-horsepower engines demand.
Using Computational Fluid Dynamics (CFD), Holley optimized the Holley Gen 3 Ultra Dominator Carburetor for smoother, more efficient airflow through its fully machined, big-bore venturis. An integrated idle bypass valve allows precise idle adjustments without affecting throttle plate position, while the extended air cleaner flange makes scoop installation simple.
The high-capacity fuel bowls hold 20% more fuel to prevent starvation, with internal baffling and a fuel shelf to reduce aeration and control slosh under acceleration. Features include 12-hole billet booster inserts for superior fuel atomization, fully tunable billet metering blocks, dual 50cc accelerator pumps, and factory TPS mounting points for data acquisition.
Built from lightweight all-aluminum construction with a Hard Core Gray finish and black anodized billet accents, this carburetor is race-ready and 100% wet-flow tested before it leaves Holley.
Key Features:
• 1150 CFM airflow for extreme horsepower race engines
• Taller main body for improved airflow
• 20% larger fuel bowl capacity with baffling
• Fully tunable billet metering blocks
• Dual 50cc accelerator pumps for instant throttle response
