Holley Double Pumper carburettors are a perfect performance upgrade for hot street cars and race vehicles. Double Pumper carburettors are an American icon when it comes to performance carburettors. From their roots as the premier carburettor on many factory muscle cars to powering thousands of vehicles across the finish line, the Double Pumper is a great choice whether you are burning up the street or the quarter mile.
The Ultra Double Pumper carburettors feature all aluminium construction and are equipped with metering blocks and a base plate made from 6061-T6 billet aluminium. They weigh in at approximately 5 lbs. less than a comparable zinc carburettor.
The new Ultra Double Pumper carburettors have an enhanced fuel curve for optimum performance, with many more features such as aluminium construction; anodised billet aluminium metering blocks and base plate; 4 corner idle for precise idle control; dual accelerator pumps for additional fuel under initial acceleration; mechanical secondaries for great performance; clear fuel level sight plugs for easy, no mess fuel level adjustments; Ford automatic transmission kickdown for use on popular Ford transmissions; four vacuum ports for all necessary vacuum accessories; and for the first time on a Double Pumper, factory pre-set electric choke for easy, fast cold start-ups.
The clean, polished look coupled with Blue metering blocks and throttle body will certainly set your ride apart whether you are at the show or track.
