Check out our dyno results on one of our 572 engines that we were testing. This particular build ideally should have had a 950cfm carb on it but we were just doing a test to see the range limits on the carb. For engine build in this hp range we strongly suggest using our ATM 950cfm. Every engine we have tested have showed great HP and TQ numbers with the ATM carbs. We will soon have more various dyno results showing the hp numbers on all the ATM carbs.

ATM’s most versatile street/bracket race gas carburetors are its XRSB Series that feature a 4150-style flange in sizes from 650cfm all the way up to 1050cfm. It is the perfect blend of a precision die cast aluminum QFT™ carb body with ATM 2-circuit, 5-emulsion billet metering blocks and a billet aluminum throttle body. The idle and high-speed air bleeds and the idle fuel feed and power valve channel restrictions can be changed to tailor a precise fuel curve your application. Incoming fuel is managed by Braswell™ Fuel Chute Lite dual inlet, dual sight-window fuel bowls. They are setup for 7/8”-20 inverted flare fittings that provide a tight, leak-resistant seal. The billet components add durability for frequent calibration changes and strength for the extreme throttle action associated with racing. Gas XRSBs come with a silver polished finished and black anodized billet metering blocks and billet throttle bodies.

GAS ATM Innovation’s XRSB is a step up from its XRSC series. While it shares many of the same features with the XRSC, the XRSB is intended for racers that frequently take apart their carburetors for precise tuning changes – the billet metering blocks add another level of durability over die cast components. The billet throttle bodies are stronger and more precise too. Plus there is more detail work like “slabbed” throttle shafts that promote smoother flow and less turbulence. ATM’s XRSB carbs use the QFT™ 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, 5-emulsion billet metering blocks with 4-corner idle adjustment, the XCTB 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 Braswell’s™ Fuel Chute Lite 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. All XRSB Series carbs are available for gas, methanol and E85 fuels. Gas XRSBs come with a polished silver finish and black anodized billet metering blocks and billet throttle bodies that have vacuum advance and PVC tubes installed.

ATM INNOVATION: WHO WE ARE

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”.
