Product Details

The Holley 0-80577SA Supercharger XP Carburetor is engineered specifically for draw-through supercharger applications, delivering exceptional performance for blown big block Chevrolet engines. This precision-calibrated 750 CFM carburetor features factory tuning optimized for 2x4, 871, and 1071 blower setups, providing the perfect fuel delivery for your forced induction system.

Performance Features:

  • Mechanical secondaries deliver instant throttle response for perfect off-the-line launches
  • Boost-referenced power valve ensures proper fuel enrichment under acceleration and boost conditions
  • Dual 30cc accelerator pumps provide additional fuel delivery during initial acceleration
  • Contoured venturi inlet offers balanced airflow distribution for increased horsepower
  • Dual-feed fuel inlets maintain constant high-volume fuel delivery under demanding conditions

Tuning and Adjustability:

  • Screw-in air bleeds enable precision tuning capabilities for dialing in your specific combination
  • 4-corner idle system allows precise control of idle quality and air/fuel distribution
  • Factory calibration for big block Chevrolet 2x4, 871, and 1071 blower applications

Quality Construction:

  • Tumble-polished finish provides a brilliant shine and corrosion resistance
  • Throttle lever cut-off design provides clearance for sideways mounting applications
  • 100% wet-flow tested by Holley technicians to ensure it arrives ready to run

This carburetor is designed for draw-through supercharger installations where the carburetor is mounted before the blower, making it ideal for traditional street rod and muscle car blower setups. The boost-referenced power valve and specialized calibration ensure proper fuel delivery throughout the entire RPM range.
