850M3A AED Pro-Series HP Race Carburetor, Alcohol

Where rules permit and you need the latest in induction technology, this should be your only choice. Our Pro-Series feature all new HP castings, New Billet fully adjustable metering blocks, and Billet Baseplates for 4150 style carburetors in 2012. These are absolutely the finest castings for Performance Carburetion ever produced! They allow us to achieve extremely high flow rates without sacrificing acceleration or torque. We have achieved over 900 cfm flow rates with relatively small venturi sizing which increases signal strength and fuel atomization. We have found our new Pro-Series to make more torque and power over a wider rpm range than anything previously obtainable. Our new Pro-Series is available in a variety of sizes and flow rates. They come with: machined throttle plates and shafts and high flow screws; fully CNC machined, centered, and CNC ported main body to specified size (1.400" - 1.600") based on application; all fuel circuits sized and calibrated per application; New Custom Machined Boosters increase Power an Torque; new aluminum bowls with large sight windows; screw in air correctors for all circuits; four corner idle circuits; all throttle bores "Wet-Flowed" to balance and correct air-fuel ratios; plus many other features.
