SA Extreme, Large Butterfly Carburetor - Choice of Fuel
  • Extensively modified, stock-appearing carburetor that produces the most HP possible utilizing a stock carb body.
  • In addition to having the largest Venturi area of any of our other bored carbs, the butterfly size has been significantly increased to provide 60% more airflow than a stock carb. Fuel circuits and jets have been reworked to maintain proper mixture.
  • Similar to our Stage 3, but has additional work on inlet side (hand-worked for ~10% more flow)
  • May have internal or external epoxy
  • No choke
  • All Stage 4 carbs are dyno-tested before shipping. Dyno testing shows these carbs to produce up to 1.0+ HP more than the standard bored (stock butterfly) and over 2+ HP more than a stock carb with only marginal loss in low-end and idle quality.
  • Venturi is CNC milled and is oval shaped to maximize volume and velocity. Equivalent bore size (area) is greater than a .670" bore
*Note: Stage 4 carbs are built to order and may take one week to ship.
