Holley Performance Products is proud to announce the introduction of their all new Ultra Street Avenger and Ultra Double Pumper Carburetors designed for improved performance, weight savings and show quality looks.

Holley Ultra Street Avengers and Ultra Double Pumpers

 Holley Ultra Street Avenger Carb

Ultra Street Avengers and Ultra Double Pumpers are made totally from aluminum, which allows them to be 5 lbs. lighter than their zinc predecessors. The aluminum construction allows them to hold their shine much longer as well. They come tumble polished from the factory, but can easily be hand polished. The metering blocks and base plates are made of 6061-T6 billet aluminum for added strength, mating surface integrity as well as good looks. The metering blocks and base plates come on the carbs in Red, Blue or Black anodizing.

Also new, is a built-in, clear fuel level sight window, which makes for easy float adjustments. The Ultra Street Avengers come with vacuum secondaries, are available in 670 and 770 CFM and have all of the bolt-on-and-go features that made the original Street Avengers popular. The Ultra Double Pumpers are available in 650 and 750 CFM and come with mechanical secondaries and electric chokes. Both feature four corner idle circuits for precise tuning and both have enhanced fuel curves for optimum performance.

Holley Ultra Dominators

 Holley Ultra Dominator Carburetor

The new Ultra Dominators feature all aluminum construction, which saves 3.8lbs of the top of the engine. The Ultra Dominators feature 6061–T6 billet metering blocks with changeable emulsion, idle feed, and power valve restrictions, a fully hand polished top and venturii for maximum airflow and less air turbulence, Teflon coated slabbed throttle shafts with low profile, button head screws mated to lightweight anodized aluminum throttle plates improve airflow, Fully adjustable external linkage provides 1:1, progressive, or soft progressive throttle activation, 12 hole anodized billet booster inserts for superior fuel atomization, and aluminum dual inlet fuel bowls with built in clear sight glasses are just a few of the features on the new Ultra Dominator.

The clean, polished look coupled with Red, or Black metering blocks, booster inserts and throttle plates will certainly set your ride apart whether you are at a show or the track.
