By popular demand, Holley is expanding the draw-thru supercharger carburetor line to now include the XP series. Like the existing HP line, these are available in 600, 750, and 950 CFM flow rates and standard polished with black accents. The feature-laden XP includes a contoured venturi inlet for balanced air flow, screw in air bleeds for precision tuning capabilities, high flow billet metering blocks, billet base plate, and Dominator style fuel bowls which allow plumbing from either side. Supercharger XP carburetors also have a unique capability that allows their power valves to reference the intake manifold vacuum below the supercharger. This allows the power valve to operate as it should, based off intake manifold vacuum. A power valve provides further enrichment to the main metering system under load (low vacuum) conditions. Holley XP carburetors are the standard for square bore race carburetors. Race-Ready out of the box!
Features:
- Tumble polished shiny finish for good looks
- Designed for use on the WEIAND® 671 supercharger (big block Chevrolet/Chrysler 392) or WEIAND® 871 supercharger (small block Chevrolet/Chrysler 426)
- Contoured venturri inlet offers balanced airflow for increased horsepower
- Screw in air bleeds for precision tuning capabilities
- Dual 30cc accelerator pumps for additional fuel under initial acceleration
- Dual feed fuel inlets for constant high volume fuel delivery
- 4 corner idle allows you to precisely control your idle system
- Mechanical Secondaries for perfect off the line launches
- Boost referenced power valve for proper enrichment under acceleration
- Throttle lever cut off for clearance on a sideways application
- 100% wet-flow tested by Holley technicians to assure it arrives ready to run!

Good deal

Seems a bit thinner than my last two, but they did come together for the price of one. Seems to be of good quality non the less. Fits well in my 2014 Subaru forester
