Ultra Street Avenger & Ultra Double Pumper Carburetors



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.

 

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.

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.
