This is a beautiful way to top off your fuel injection project.  The intent was to make a four barrel throttle body that flows well and isn't the typical chunky billet.  These 4150 4bbl flanged, billet 6061 Aluminum throttle bodies are CNC machined on a 5 Axis machining center in Lenoir City, TN.  They are then polished and buffed by hand before assembly.  They have been designed using CFD software to reduce slow moving boundary layers and turbulence.  The integrated Throttle Position Sensor uses reliable one million cycle Panasonic internals.  This eliminates the large plastic TPS hanging off the side.  The linkage is variable to allow the user to decide if the operation should be more or less progressive.  The shafts are mounted on double sealed INA roller bearings rated to turn 15k RPM.  One prototype was cycled 128,000 times on a computer monitored test stand before logging thousands of trouble  free miles in a daily driven test vehicle.  They should work with any aftermarket multiport computer that allows calibration of the throttle position sensor.
