Annular Flow Boosters deliver near EFI-like drivability that you can feel as soon as you step on the gas. Fuel distribution is refined by eight equally spaced orifices in the booster rings that replace down-leg boosters which simply dump raw fuel into the venturi.\u003c\/p\u003e\n\u003cp\u003eFlat spots are completely eliminated, and throttle response in the low- to mid-RPM range is improved tremendously without sacrificing that top-end power that Edelbrock is known for. The AVS2 is unaffected by engine backfires since there are no power valves to blow out. For fast and simple part-throttle tuning, metering rods and springs can be changed in seconds without carburetor removal or fuel draining. AVS2 carbs have the unique ability to \"hold a tune\" when compared to other carburetors. Your tuning and adjustments stay unchanged, so performance remains consistent.\u003c\/p\u003e\n\u003cp\u003eUpdated primary and secondary booster clusters in the AVS2 offer the most accurate and up-to-date calibration available for today's fuels and octane levels. Additionally, the unique Qwik-Tune Secondary Air Valve allows for limitless calibration of the secondary circuit. Adjustments can be with simple hand tools in seconds to suit your application. The AVS2 features a two-piece ease-of-tuning design that allows you to make float level adjustments or replace internal components without draining the fuel from the carburetor or removing it from the engine.\u003c\/p\u003e\n\u003cp\u003eThe AVS2 800 CFM is available with a manual (#1912) or electric (#1913) choke in satin or chrome-like EnduraShine finish. All AVS2 Series carburetors, like Edelbrock's popular Performer Series and Thunder Series AVS, are designed, manufactured, assembled and calibrated by Edelbrock in the USA.\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/2e8eaee940255b067251f5f46240cb0f.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":46885426266361,"sku":"EDE1913","price":514.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/5428\/0953\/files\/7f4db2d1bcb81b2dc6d3a9a6a12f21ef.jpg?v=1758746798","url":"https:\/\/octanehaus.com\/products\/edelbrock-carburetor-thunder-series-4-barrel-800-cfm-electric-choke-calibration-satin-finish","provider":"Octane Haus","version":"1.0","type":"link"}
