1200 Cfm 4 Barrel 4150 Billet Throttle Body

This new Speedmaster Throttle Body is designed to produce smooth, stable air flow at any rpm. The entire throttle body begins as a billet of 6061- T6 aluminum for superior quality and is introduced to a state-of-the-art CNC machine. From here it is precisely machined resulting in overall accuracy to within 0.001"!

The air inlets are formed with radiused openings to supply a smooth entrance for the air.

Brass throttle blades control vibration & reduce thermal expansion Bearing mounted butterfly shafts for smooth throttle action Shorter height for better airflow, easier packaging for tight hood clearance and reduced weight Comes complete with billet arms and stops. Provision for TPS on unit
