With the airflow dynamics and fuel metering accuracy of a racing unit, Speed Demon is the most formidable street/strip carburetor on the market. It boasts balanced, high-velocity airflow with matched booster response. The choke tower walls and contours and the venturi air entries are smooth and free-flowing with radii designed to maximize airflow. A new die-cast technique, Concentracast, provides the most accurate, consistent method of manufacturing concentric venturi, virtually eliminating any misalignment or core shift.Note: Demon float bowls use special 9/16" x 24 TPI inlet fittings available in standard, filtered, or swiveled sizes.
