This four barrel carburetor is intended for use with superchargers, and 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. Without this external referencing, the power valve would be "reading" the supercharger boost pressure, which has no bearing on the engine load.

  • Model 4150HP design
  • Designed for use on the Weiand 6-71 & 8-71 superchargers
  • Four-corner idle system
  • Replaceable air bleeds
  • Dual 30cc accelerator pumps
  • Shiny Finish
  • Mechanical secondary
  • Boost referenced power valve
  • Throttle lever cut off for clearance on a sideways application
