Wilson Manifolds now offers flanged high-performance single-bore throttle bodies for forced induction EFI engines. The flanged mouth is counter-bored to accept a machined aluminum mating ring. The other end of the mating ring will accept a 4-inch O.D. alloy tube, which can be welded to the mating ring. The setup allows for no steps, clips or restrictions throughout the whole system. Wilson’s high-flow throttle bodies were developed from scratch using state-of-the-art modeling software to produce designs that yield maximum flow per square inch of cross-sectional area. All Wilson throttle bodies are machined from billet 6061-T6 aluminum using precision CNC machines for consistent quality and decreased weight. Features include brass throttle blades to control vibration and reduce thermal expansion, and shot-peened throttle shafts specially machined to decrease cross-sectional area for improved airflow.
