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!

Refreshing and amazing toner

Love this toner. First thing I do when I wake up or get out of the shower is spray this. Scent of the rose is subtle. Refreshing. I’ve been using this product for over 5 years and nothing can replace it

Refreshing, gentle and soothing
Scent: Rose Petal, Size: 3 ounce (Pack of 1)
The Thayers Alcohol-Free Witch Hazel Facial Mist is amazing! It feels incredibly refreshing on the skin and provides instant hydration without any stinging or dryness. I love that it’s alcohol-free, so it’s gentle enough for sensitive skin while still helping to tone and soothe.
The mist is fine and evenly distributed, making it perfect for a quick pick-me-up during the day or as part of a skincare routine. My skin feels soft, calm, and revitalized after each use.
Overall, this facial mist is a must-have for anyone looking to refresh, hydrate, and care for their skin naturally. Highly recommend!

This mist makes my skin feel so soft and hydrated! I use it after cleansing or whenever I need a glow boost. Smells amazing and never irritates my skin total staple in my routine! These two are a match made in skincare heaven! The pads keep my breakouts under control, and the rose mist adds the perfect glow and hydration. Together they make my routine feel like a mini spa moment.

Scent: Rose Petal, Size: 8 Fl Oz (Pack of 1)
This is one of my favorite sprays. It feels so good, gentle on my skin, I personally like the smell because it smells like roses. It moisturizes my skin, I like to put it on even in the middle of the day over my makeup, it seems to freshen it up. My skin loves this spray, it's very refreshing. I will definitely be buying again.
