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
- Big block Chevrolet 2x4, 871 & 1071 blower calibration
- 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!

Machine quality
Color: RYLCC-BLK, Color: RYLCC-BLK
For the price not bad, machining quality flawed. Could have been better. More of an aesthetic quality, other than that defect not bad.

Excellent Cigar Tube!
Color: RYLCC-BLK
This impressive cigar carrier is a complete and safe way to carry one cigar. This holder is light aluminum; you can throw it in a range bag, backpack, or any other carrier without worry. This carrier has a punch for your cigar and a built-in cigar stand. I love my cigar carrier; I have just enough capacity to enjoy my cigar.

Picture is misleading
Color: RYLCC-BLK
Great product! Good quality! The picture of the product is a little misleading as it looks like there are 2 tubes instead of one.

Perfect sized wrist-rest!
Size: Compact, Size: Compact
Great wrist-rest! Very squishy and feels comfortable & cool even after hours at the computer. The rubber gripper bottom is effective & it never shifts around for me. Also, love that it fits the length of my 75% keyboard & my boyfriends 60% Wooting 60HE keyboard perfectly
