Elite Engineering’s Vacuum Venturi Barb 1/2" Vaccum Lines

Designed to be our highest flowing Check Valve to date!

This device generates vacuum as the air flow passes the angled open end using a Venturi effect. The greater the velocity past it, or speed of the flow, the more vacuum it
generates. This provides the vacuum to continue evacuation when accelerating or at wide open throttle when no usable vacuum is present in the intake manifold. Our check valves will automatically open and close to always default to the strongest vacuum source so full time evacuation takes place. With a naturally aspirated application, this is placed close to the inlet of the throttle body, but making sure that it is not so close as to interfere with the blade.

On a Turbo or Centrifugal SC you would place this at the inlet to the turbo or centri supercharger. On a top mount PD type supercharger (Magnason, Whipple, E-force, etc.) you would do it the same way as a naturally aspirated application
as shown in the pictures, the reason - the supercharger lower plenum replaces the intake manifold.

Some key features:

• Custom machined aluminum
• Hose Barb Ends
