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!

Extra fine glitter
Color: Gold
Extremely fine. I plan on adding it to my spf body oil. Hoping it doesn’t clog the line but I absolutely love this! The pump is so cute. I love that it’s glass. I know there are cuter ones online so you could just get this for the glitter and put it into another one that’s more ornate. It’s just so much fun. Buy it now

Perfect
I love it. It fits perfectly in my pocket book, love the color of the sparkles. Not itchy, it keeps me glowing all night long, not oily or sticky. I like the feeling and functional of it.

Gorgeous
Color: Gold
This is literally Tinkerbells best kept secret. I’ve never seen a cuter bottle or a better
Spray. Accidentally leaves a hint of shine behind no matter where you go.

Nice but fragile.
Glitter was nice until it dropped out of my hand onto my vanity 1 foot and the plastic snapped off the bulb. Fake metal.
