Ported Vs Full Vacuum Advance at Clarence Turner blog

Ported Vs Full Vacuum Advance. This is the most misunderstood item on oldschool carbureted engine tuning.link. The vacuum advance mechanism is usually connected to this port, controlling ignition timing. With full time it is ever present so you might find that. 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. Ported vacuum is zero at idle, comes in just off idle, then goes away as the throttle is opened further. 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. Improve power, throttle response, and economy!!! Vacuum advance is purely an idle to slightly off idle to low rpm cruise thing. Using a ported vacuum can help improve fuel economy by advancing ignition timing. This system allows the engine to produce more power when the vehicle is at low speeds, using the same amount of fuel. I could see where it could be.
