WebJan 22, 2016 · For example, if the dewpoint is 59 F (15 C), and the manifold pressure is 29 inches, the correction is -0.5 inches, thus we would use a m.p. of 28.5 inches when using the power charts. The dewpoint cannot be higher than the air temperature, and air temperature generally decreases as the altitude increases. WebVacuum is a unit used to measure changes in pressure. The standard unit for measuring Vacuum is inches of mercury. Manifold vacuum measures the difference in air pressure from the inside of the intake manifold, to the air pressure on the outside of the engine. A difference of 1 Pound per Square Inch in pressure will move a column of mercury 2. ...
