SA Extreme, Large Butterfly Carb

Extensively modified stock appearing carb producing the most HP possible utilizing a stock carb body.

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. No Extrenal Epoxy. Choke is removed

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