By popular demand, Holley is expanding the draw-thru supercharger carburetor line to now include the 4150 XP Series. Like the existing HP line, these carbs are available in 600, 750, and 950 cfm flow rates—and standard polished with black accents. The feature-laden XPs include a contoured venturi inlet for balanced airflow, screw-in air bleeds for precision-tuning capabilities, high-flow billet metering blocks, billet base plate, and Dominator-style fuel bowls which allow plumbing from either side. Supercharger XP carburetors also have a unique capability that allows their power valves to reference the intake manifold vacuum below the supercharger. This enables the power valve to operate as it should, based off intake manifold vacuum. A power valve provides further enrichment to the main metering system under load (low vacuum) conditions. Holley XP carburetors are the standard for square bore race carburetors. Race-Ready out of the box! Order the model with options preferred for your vehicle. Product details: * Tumble polished shiny finish for good looks * Application-specific blower calibration * Contoured venturi inlet offers balanced airflow for increased horsepower * Screw-in air bleeds for precision-tuning capabilities * Dual accelerator pumps for additional fuel under initial acceleration * Dual feed fuel inlets for constant high-volume fuel delivery * 4-corner idle allows you to precisely control your idle system * Mechanical secondaries for perfect off-the-line launches * Boost referenced power valve for proper enrichment under acceleration * Throttle lever cut off for clearance on a sideways application * 100 percent wet-flow tested by Holley technicians to assure it arrives ready to run

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 pumps
