AED Ultra HO-Series Carburetors: Serious Carburetion for Serious Performance

  • thumbnail

What happens when you combine a Holley Ultra HP main body and fuel bowls with AED’s years of carburetor tuning expertise? The Ultra HO-Series carburetors, of course. These are not carburetors for the faint-hearted—they are designed for use on serious street performance, bracket race, circle track, and off-road race engines.

Available in 650 and 750 cfm versions, the mechanical secondary carburetors feature AED’s custom CNC-machined billet aluminum metering blocks. Each carburetor is hand-built and blueprinted, then wet-flowed to provide a balanced fuel delivery curve across the engine’s RPM range. That makes an Ultra HO-Series carburetor as close to ready to run as you can get.

Other features include:
• Four corner adjustable idle circuits
• Adjustable idle air bleeds
• Aluminum fuel bowls with large site glass
• Dual fuel inlets
• Dual accelerator pumps
• Dual vacuum ports
• Reusable gaskets and washers
• Choice of red or black metering blocks
