SA Extreme, Large Butterfly Carburetor - Choice of Fuel
Extensively modified, stock-appearing carb that produces the most HP possible utilizing a stock carb body. No external epoxy

In addition to having the largest Venturi (>.670) 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. Choke is removed.

Stage 3 carbs have no expoxy on thjem, however they flow same as the stage 2 carbs.

Dyno testing shows these carbs to produce up to 1hp more than a standard bored (stock butterfly) carb, and over 2hp more than a stock carb with only marginal loss in low-end and idle quality.
