THROTTLE BODIES

Wilson Manifolds High Flow Throttle Bodies were developed using the latest computer modeling software and test equipment available to produce designs that yield the maximum flow per square inch of cross-sectional area. This results in maximum power for any given throttle body type and size. Four barrel style throttle bodies are designed to work with the Wilson line of billet spacers and incorporate a tapered and radiused throttle bore and precisely machined progressive linkage for smooth throttle operation. They also feature inward opening throttle blades to eliminate any part throttle directional influence by the blades that can cause poor air distribution. Wilson has redesigned their Dominator style throttle bodies to incorporate improved throttle linkage and to significantly reduce overall mass. All throttle bodies feature brass throttle blades to control vibration and reduce thermal expansion. Throttle blades are fastened to the throttle shaft using aircraft quality hardware that is both locktited and peened to assure positive retention of the blades. Throttle shafts are machined to decrease their cross-sectional area, which increases the actual cross-section available for airflow. All throttle bodies are machined from 6061-T6 aluminum on precision CNC machining centers for consistent quality and light weight. High flow throttle bodies are available in 4500 and 4150 four barrel styles as well as many single bore sizes in Ford style. Wilson also now offer a throttle by wire version of the popular 90 mm LS1/LS6 design, which allows a 90mm throttle body to be installed on a late model Corvette when using 90mm LSX intake manifold.
