EMPI's Single 44HPMX Carburetor Kit offers the performance of the two barrel HPMX carburetor and the ease of only having one carburetor. The 44HPMX carb is completely tuneable with air and fuel metering all being adjustable and the butterflies are drilled to help maintain a smooth idle. The carburetor kit includes the 44HPMX carburetor with linkage kit, a chrome air cleaner assembly with gauze filter, chrome velocity stacks, the isolated plenum center intake manifold (for use with single or dual port end castings), fuel line and mounting hardware. The single, two barrel carburetor kit fits Type 1 1300-1600 based engines. We recommend the single 44HPMX carburetor for displacements over 1800cc. The carburetors are test run and adjusted for smooth performance out of the box. Fits 1966-1974 Beetle and Super Beetle. Will fit in 1963-1971 Bus and 1973-1974 Things if the idle jet vent tubes and velocity stacks are removed and a smaller air filter (8805) is used.

EMPI's 44HPMX Carburetor kits include:

  • Chrome Velocity Stacks
  • Air Craft Style Heim Joint Linkage
  • Isolated Plenum Aluminum Intake Manifold (fits single or dual port end castings)
  • Chrome Air Filter with High Flow Gauze Element
  • Mounting Hardware, Gaskets & Instructions

EMPI's 44HPMX Carburetor comes with the following parts installed:

  • 0.60 Idle Jets
  • .140 Main Jets
  • .160 Air Correction Jets
  • .350 Exhaust Pump Valve Jets
  • 0.55 Accelerator Pump Jets
  • F-11 Emulsion Tube
  • 30mm Venturis

What size carburetors do I need?

In general we use 40mm single carburetors for engines up to 1800ccs. 44mm carbs are used for 1800cc and larger engines. Cams, heads, valve sizes and other factors will determine which carburetor set up works best. At the end of the day though, when in doubt, go larger as venturis and jets can all be changed to make a larger carb suit a smaller engine as needed.

Why choose an EMPI HPMX carburetor over a Weber IDF?

Don't get us wrong, we're suckers for performance and when it comes to VW engines and performance carburetors, few will argue with the quality and performance that comes with the Weber name. That being said, there are better Weber versions than others with the Italian versions being the more preferred. So when EMPI decided to take on the task of reproducing one of the most popular VW performance carburetors they went to the best and made it better. They started with a 44 IDF carburetor as a base for the casting for both the 40HMPX and the 44HPMX carburetors. Some of the first improvements was updated circuitry and profiled throttle shafts to flow better right out of the box compared to the Weber. Now on their 4th generation, having made improvements along the way the HMPX carbs now feature a cast in enrichment plate block off, a vacuum port and extended idle jet tubes to help eliminate clogged idle jets. So, why choose an HPMX Carburetor? Because it works just as well, if not better than a IDF carburetor, it's less expensive, and all the components, jets, gaskets and parts are all interchangeable with the IDF. Why pay more for less?!
