HOLLEY GEN 3 ULTRA DOMINATOR CARBURETOR 1250 CFM #0-80908HB

The Holley Gen 3 Ultra Dominator Carburetor (Part #: 0-80908HB) is a 1250 CFM racing carburetor designed for maximum horsepower applications. Originally developed for NASCAR® in 1969, the Dominator® has evolved into Holley’s flagship race carb, and the Gen 3 Ultra takes it to the next level with an all-new main body, state-of-the-art calibrations, and high-volume fuel bowls.

The patent-pending Gen 3 main body is 5/16” taller, allowing for larger radius air entries optimized using Computational Fluid Dynamics (CFD) for smoother airflow into fully machined, big-bore venturis. An integrated idle bypass valve enables precise idle adjustments without altering throttle plate position, while the extended air cleaner flange simplifies scoop installation.

The Holley Gen 3 Ultra Dominator Carburetor features fuel bowls with 20% more capacity, internal baffling to control slosh, and a fuel shelf to reduce aeration. Additional highlights include 12-hole billet booster inserts for superior atomization, fully tunable billet metering blocks, dual 50cc accelerator pumps, TPS mounting points, and knurled curb idle screws for tool-free adjustments.

Finished in Hard Core Gray with black anodized billet accents, this carburetor is lightweight, durable, and 100% wet-flow tested for race-ready performance.
