Holley Ported Vacuum At Idle at Edwin Whitlow blog

Holley Ported Vacuum At Idle. while at a show today spoke to someone that suggested i try ported vacuum instead of manifold vacuum to prevent. ported vacuum is zero at idle, comes in just off idle, then goes away as the throttle is opened further. As the pedal is pushed, the vacuum increases. begin by adjusting the driver side idle mixture screw in (clockwise) approximately 1/8th of a turn while. I'm trying to raise the idle a bit,. the port is above the throttle plates, thus, as throttle goes open, it'll have a vacuum signal on it at rpm's above idle. on holley's, the cure is to drill a 0.090 hole in each front throttle blade to allow air in while keeping the throttle. the difference between ported and full manifold vacuum only occurs at idle. A proper timing advance curve uses rpm.
