Dominator HP #71 Air Bleed

The Dominator HP #71 Air Bleed from HOLLEY is an essential tuning component for high-performance carburetor systems, designed specifically for serious enthusiasts and professional mechanics who demand precision fuel delivery and engine response. Air bleeds control the air-fuel mixture ratio by regulating the volume of air entering the fuel circuits within the carburetor, making them critical for achieving optimal performance across varying engine loads and RPM ranges. Whether you're building a street machine, circle-track racer, or naturally aspirated engine looking to maximize power output, selecting the correct air bleed size is fundamental to carburetor calibration.

The #71 specification denotes a precisely sized orifice that meters air emulsion in the main and idle fuel circuits, allowing HOLLEY engineers to fine-tune atomization and combustion efficiency. Compact at just 3.5 inches in length and weighing only 0.03 lbs, this air bleed integrates seamlessly into HOLLEY Dominator HP carburetors without adding bulk or complexity. The brass construction and precision drilling ensure durability under sustained high-RPM operation while maintaining consistent air-fuel ratios that prevent stumble, hesitation, and lean-out conditions that plague improperly calibrated systems.

This air bleed is essential for tuners working with HOLLEY Dominator HP carburetors on engine builds ranging from 400 to 650+ horsepower naturally aspirated platforms. Installation requires removal of the carburetor bowl and careful positioning within the air bleed circuit—a task suited for experienced builders or professional shops with carburetor expertise. When paired with proper needle-and-seat selection, fuel curve adjustments, and dyno tuning, the #71 air bleed helps unlock consistent power delivery, improved throttle response, and reliable starting across ambient temperature variations.
