      XRB-1050AB2 Sold Each - 4150 Flange Methanol on a Supercharger

      ATM’s Methanol XRB Series are our most versatile "race" carburetors with a 4150-style flange and "no vacuum ports". They are the perfect blend of a precision die cast aluminum ATM™ carb body with ATM 2-circuit, 4-emulsion billet metering blocks. Fuel is managed by ATM™ all aluminum dual inlet, dual sight-window fuel bowls and the billet aluminum throttle-bodies have vacuum tubes for vacuum advance and PVC hookups. They are available in 5 sizes from 650cfm to 1050cfm (4150 flange) applications.

      Methanol XRBs come with a dichromate gold corrosion-resistant finish and black anodized billet metering blocks and throttle bodies.

      ATM’s XRB carbs use the ATM™ die cast aluminum carb body that has a fully contoured high-flow air horn and externally changeable idle- and high-speed air bleeds. When combined with ATM’s 2-circuit, 4-emulsion billet metering blocks with 4-corner idle adjustment, the XRSB becomes one of the most “tuneable” race carbs on the market. These billet metering blocks also have changeable idle fuel and power valve channel restrictions.

      Dynamic fuel handling is important in hard-cornering racecars and ATM’s™ all aluminum dual inlet, dual sight-window fuel bowls were designed exactly for this purpose. They are fitted with 7/8”-20 inverted flare fittings for leak-resistant connections.

      They are available in 5 sizes from 650-1050 CFM (4150 style).

      ATM Innovation is a new high performance company backed by one of the most experienced teams in race carburetor technology. It’s true “that the apple doesn’t fall far from the tree” and CEO Angela Benoit Neely has spent years following in her father’s (Marvin Benoit [founder of Quick Fuel Technology™]) footsteps. She is launching ATM Innovation with years of experience at QFT™ under her belt.

      Angela’s mission statement is boldly stated on the banner of this website. It’s the “NEXT Generation In Fuel Systems” which means that ATM is innovating and re-inventing race carburetors and throttle stops as we now know them. A good example is its new Double D™ throttle stops that not only restrict horsepower when applied, but actually increase horsepower when they are fully open.

      Her motto is “we build parts for racers by racers”. Performance, quality and customer service is the foundation for ATM Innovation. And Angela and the ATM Team are already delivering on these promises with a World Championship in one of the toughest divisions in Lucas Oil Drag Racing – Super Gas.

      Angela proudly reflects on ATM and what they’ve accomplished so far, “I will forever be indebted to my father and family for the education and opportunities they have provided. The new ATM Team is truly the Next Generation, building state-of-the-art, high performance and racing fuel systems”.
