Edelbrock has launched a new a high-performance carburetor, the AVS2, that the aftermarket-parts company says delivers smoothness near that of electronic fuel injection.

“The AVS2 Series is based on the popular Thunder Series AVS utilizing the innovative Qwik-Tune Secondary Air Valve that provides unlimited calibration of the secondary circuit for the most precise tuning across the entire RPM range,” according to a new release.

“Edelbrock engineers managed to make the AVS design even better by adding Annular Flow Booster technology. The AVS2 Series boasts new calibration and delivers superior atomization.”

The annular flow booster’s eight orifices provide fuel atomization instantly as the butterflies open, an improvement over standard down-leg boosters by smoothing out throttle transitions without any flat spots, the release explains.

“With an AVS2 carburetor, you feel the difference as soon as you step on the gas,” the company says.

“Flat spots that are often encountered when a carb transitions from idle to wide-open-throttle are completely eliminated, and throttle response in the low- to mid-RPM range where you spend 90 percent of your driving time on the street, is improved tremendously. Additionally, there is no sacrificing that top-end power that Edelbrock is known for.”

The AVS2 features two-piece aluminum construction and a design that allows easy tuning when changing components or making adjustments without draining the fuel or removing the carb from the engine, Edelbrock notes.

The AVS2 is designed, manufactured, assembled and calibrated by Edelbrock’s carburetor division in Sanford, North Carolina.  The carburetor is available in 500, 650 and 800 CFM with manual or electric choke, the release says, in satin or “our chrome-like EnduraShine finish.”
