Manifold Vacuum Vs Carb Vacuum at Bill Voigt blog

Manifold Vacuum Vs Carb Vacuum. Most vacuum advance dizzys (on spridgets) use the carb for the advance. The general answer to the basic question ported vacuum or manifold vacuum to dist? is yes. Unplug one of the lines from the distributor if has vacuum at idle it is manifold vacuum. For some reason choosing between which type of vacuum to run off the carburetor or tbi efi is a big controversary. In order to function properly, in the manner stated in the article, the vacuum canister should be connected to a *manifold* vacuum port (sourced from below the carb throttle plates), not “ported” vacuum (above the throttle plates). Ported vacuum is taken from above the throttle plate, while manifold vacuum is taken below it… that’s right! Both types offer unique benefits in fuel efficiency and engine control Vacuum retard dizzys used the manifold. Try both ways, see which works best with your car. Understand the differences between ported vs manifold vacuum in car engines.
