What Is Ported Vacuum Advance at Ali Clarence blog

What Is Ported Vacuum Advance. Ported vacuum feeds vacuum from above the throttle plate. That means there is no vacuum sourced to the canister at curb idle. This type of vacuum advance was found. This means no vacuum at idle (because the throttle plate is closed). With ported advance, vacuum is applied once the throttle is opened past curb idle. Using a ported spark advance will still allow the vacuum advance to do its job at steady cruising, but all of the benefits of idle. As the pedal is pushed, the vacuum increases. It’s also important to mention that in most applications, the vacuum advance canister is connected to what is called ported manifold vacuum. Which should you use, and should you even use vacuum advance at all? The vacuum port acts as a source of vacuum pressure, needed by a vacuum advance mechanism to adjust the ignition timing accordingly. All vacuum movements are exactly the opposite from being full vacuum. This mechanism uses the strength. If you are running your ford on ported vacuum i feel sorry for your engine and how you are gimping it by using the emission era form of vacuum advance over the proper non emission era manifold vacuum.
