How do I select the correct valve for my universal application?

Selecting the correct universal valve for your vehicle requires a baseline knowledge of your needs and intended air routing system. First, you need to identify the size of the valve that would be sufficient for the volume of air you will be discharged through the valve. Next, you need to determine if you plan on plumbing the air back into the intake tract, releasing it to the atmosphere, or a combination of the two. Some vehicles have limitations in this regard because of the air metering device being used to calculate the fuel supply to the engine. The final step in choosing the correct universal valve would be to identify which spring is supplied with the unit in its base form and to confirm that this spring is the best option for the amount of vacuum your vehicle generates.

    • What’s the difference between a “Dual Port”, a “Supersonic”, and a “Plumb Back” valve?

      Our “Dual Port” valves split the released compressed air, recirculating a portion of the air into the intake tract and removing the remaining air into the atmosphere. A “Supersonic” valve vents 100% of the compressed air charge into the atmosphere. A ...

    • Why/when/how would I adjust the valve?

      Most valves come pre-adjusted to the correct setting for your vehicle. The two possible extremes that may require adjustment are a valve that is too stiff for your application or a valve that is too soft. If the valve is too stiff, your vehicle will ...

    • How much boost can a valve hold?

      Our valves are not rated by the amount of boost pressure that they can hold. A good rule of thumb is that if the hose supplying air into the top chamber of the valve is large enough to supply an adequate volume of air, then the valve itself should ...

    • What signs indicate my valve is adjusted too soft?

      If the valve is too soft, then your vehicle will generally suffer from a valve that is open when it shouldn’t be (such as at idle) or from an extended air charge release (possibly in excess 3 seconds). If either of these conditions occur then the ...
