Holley Releases 1050 CFM Gen 3 Marine Dominator Carbs

Holley/MSD is pleased to announce the release of Holley 1050 CFM Gen 3 Marine Dominator Carburetors, which exceed performance demands whether you're out for high-speed fun or just hitting the lake for an easy cruise. All-aluminum and hard-coat anodized in a gray finish to protect against corrosion in both freshwater and saltwater conditions, they feature a patent-pending Gen 3 main body that's 5/16-inch taller than previous models. This creates large-radius air entries, which are optimized by Computational Fluid Dynamics software to deliver smoother flow into fully machined big-bore venturi.

The main body features an integrated idle-bypass valve that allows for easy idle adjustments while maintaining the correct throttle-plate/transfer-slot relationship and an extended air-cleaner flange for easy air-scoop attachment when using the available air-scoop adapter. This all-new design uses high-capacity fuel bowls with 20 percent more capacity to eliminate starvation, an integrated fuel shelf to minimize fuel aeration, and internal baffling to control fuel slosh. Holley 1050 CFM Gen 3 Marine Dominator Carburetors come complete with 12-hole billet booster inserts, fully tunable billet metering blocks, an adjustable external linkage, throttle-position-sensor mounting points, and hand-adjustable knurled curb idle screws for hassle-free adjustment. Each calibration is fully dyno tested for proven performance.
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 venturii. The main-body also features an integrated idle bypass valve that allows for idle adjustments while maintaining the correct throttle plate to transfer slot relationship as well as an extended air cleaner flange for easy air scoop attachment when using the available air scoop adapter. 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. Each calibration has been dyno tested to deliver proven performance!

Features:

  • All aluminum construction saves 3.8lbs. over original models (28% weight savings)
  • Gray anodized finish with black anodized billet aluminum metering block and booster inserts
  • Designed for use on Marine high horsepower engines
  • Fully machined from venturi throat to throttle bore for predictable & repeatable performance
