By popular demand, Holley is expanding its draw-thru supercharger carburetor lineup with the exciting new XP series. Just like the well-loved HP line, you can choose from 600, 750, or 950 CFM flow rates, all featuring a sleek polished finish with stylish black accents.

The XP series is packed with features designed to improve your driving experience. It includes a contoured venturi inlet for smooth and balanced airflow, along with screw-in air bleeds that make tuning a breeze. You’ll also find high-flow billet metering blocks, a sturdy billet base plate, and Dominator-style fuel bowls that allow for flexible plumbing options from either side.

One standout feature of the Supercharger XP carburetors is their innovative power valves, which reference the intake manifold vacuum located below the supercharger. This smart design ensures that the power valve functions correctly based on the intake manifold vacuum, providing that extra enrichment to the main metering system when you're under load and facing low vacuum conditions.

When it comes to square bore race carburetors, Holley XP carburetors set the standard. They’re race-ready right out of the box!
