When it comes to large 4700/4500-flange carburetors it’s hard to beat ATM Innovation’s XRX Series. You get a true custom built carb that is engine tested and ready-to-race right out of the box. And with the help of ATM’s Custom Shop technicians you can get your XRXs configured for anything from throttle stop racing to all-out 2 x 4 setups.
ATM starts with a QFT™ die cast main body and adds its own ATM billet 4-circuit, 5-emulsion metering blocks with 4-corner idle adjustment. It adds annular booster assemblies with custom sizes from .092”-1.05” depending upon the carb size and the application. Of course the XRX has changeable idle and high-speed air bleeds and changeable idle, emulsion, intermediate and discharge channel feed restrictions.
The final piece of the XRX puzzle is the Braswell™ Fuel Chute Lite dual inlet; dual sight glass windows fuel bowls that control fuel flow regardless of the G-forces. They have the desirable 7/8”-20 AN #8 connections that make plumbing your fuel system failsafe.
XRX Series carbs are available for gas, methanol and E85. Methanol XRXs have a gold corrosion-resistant coating with black anodized billet blocks and billet throttle bodies. They also have special gaskets and GFL diaphragms resistant to methanol fuel.
