Holley Gen 3 Ultra Dominator Carburetors 0-80902BK

Holley Gen 3 Ultra Dominator carburetors feature a brand new main body, brand new state-of-the-art calibrations, high-volume HP fuel bowls, and sizes up to 1,475 cfm! The metering blocks are fully adjustable (emulsion bleeds, power valve channel restrictors, and idle feed restrictors). These carburetors include redesigned Holley HP fuel bowls for racing. Internal baffling helps to control fuel slosh and minimize float level fluctuations in hard launching or cornering situations. The HP fuel bowls also have material added in key areas (the needle and seat, fuel inlet, and sight window areas) for added strength in demanding race environments and can be plumbed from either side.

Some of the many Holley Gen 3 Ultra Dominator carb features include:

* Main body 5/16 in. taller than the previous generation
* Designed for larger radius air entries optimized using computational fluid dynamics (CFD) software to deliver smoother flow into fully machined, big-bore Venturi
* Improved 6061-T6 billet aluminum metering blocks offering improved durability, true gasket sealing (sealing surface integrity), and brightly dipped anodizing for good looks and corrosion protection
* Power valve channel restrictors are now machined lower in the metering blocks for improved fuel delivery to the power valve circuit
* Accelerator pump channel internally drilled, eliminating the need for an external plug,
* Excess material removed for increased fuel capacity
* Snap-in-place bowl vent whistle makes removal and/or replacement easier
* 20 percent more fuel capacity vs. traditional V-bowl, eliminating fuel starvation and providing consistent air/fuel ratios
* Fuel shelf is positioned below the needle and seat to minimize fuel aeration and promote more consistent metering
* Fuel trough designed into the floor of the bowl to route fuel flow directly to the jets and assist in keeping them covered by fuel
* Clear sight windows on both sides of the bowls for easy and safe fuel level adjustments
* Built-in drain plug in the front center of the bowl provides easy access to empty the bowl (contoured entry provides smooth fuel flow directly to the needle and seat)
* Designed for use on drag race, Pro Street, or any high-horsepower engines
* All-aluminum construction saves 3.8 lbs. over original models (28 percent weight savings)
* Dual 50cc accelerator pumpsBrand: Holley
