    Holley Ultra XP 850 CFM 4-barrel carburetors give you maximum performance in a good-looking, easy-to-install package. They're calibrated to give you excellent performance with additional fuel delivery from its additional accelerator pump. Ultra XP Double Pumper carbs feature durable billet aluminum metering blocks and baseplate. Electric choke allows simplified installation and trouble-free cold starting.

    Maximum Tunability
    Holley Ultra XP carbs are wet flow tested before leaving the factory. These 4150 series carburetors allow maximum tunability from their front and rear metering blocks and dual 30cc accelerator pumps. You can dial in maximum performance by changing jets and accelerator pump cams front and rear. This allows you to keep up with the fuel demands of high horsepower, hard-launching street/strip race cars. Built in window sight plugs allow easy float adjustments on the engine and an idle bypass that allows you to get your idle just right, even with a huge cam that wouldn't idle properly with a normal carburetor.

    Maximum Fuel Flow
    Everything about the Ultra XP carburetor is designed to supply maximum fuel flow to feed your hungry engine. It features 30+ upgrades over a base model carburetor including 20% larger fuel bowls, integrated idle bypass, dual high capacity accelerator pumps and more. They also have many features designed to prevent fuel slosh to further ensure proper fuel delivery.
