ATM XRSB- 650 TO 1050 GAS   - Sold Each   ( Suck through- NOT Blow through )

COMPARE TO QUICK FUEL   BUT  little better :) 

ATMs most versatile gas carburetors are its XRSB-GAS  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 Gold  finished and black anodized billet metering blocks and billet throttle bodies.

ATM Innovations XRSB is a Methanol Drag Race Carb. . While it shares many of the same features with the XRC, 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.

ATMs 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 ATMs 2-circuit, 5-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-leaving racecars and Braswells Fuel Chute Lite dual inlet, dual sight-window fuel bowls were designed exactly for this purpose. They are fitted with the 7/8-20 inverted flare fittings for leak-resistant connections.

All XRSB Series carbs are available for gas, methanol and E85 fuels. Gas XRBs come with a polished silver finish and black anodized billet metering blocks and billet throttle bodies.
