If your scanner is showing the vacuum as PSI it can be converted to roughly 10 inches of mercury (inHg) as you increase revs the … Nettet26. apr. 2016 · So the MAP sensor on the manifold. It's obviously post throttle, which at idle should be in vacuum. Right? However it shows like 5 psi on the Accessport. Looking at Cobb's site, I see the Boost Pressure monitor is "MAP minus barometric pressure" which is 14.7 psi... okay, so to me this doesn't make sense. If I were to put a hole in the …
Intake manifold pressure at idle psi
Did you know?
Nettet15. feb. 2024 · The intake manifold is under vacuum at idle. The intercooler and everything before the throttle body will see a slight positive pressure at idle (.1-.2 psi). Take a look at the barometer reading, the manifold vacuum, and the pre throttle pressure on the screenshot. Running slight positive before TB, vacuum after. Nettet27. jul. 2016 · They can measure up to 2x the atmospheric pressure (29.4psi), so that means it can measure up to 14.7psi boost (the atmosphere is 14.7psi + 14.7psi from the turbo/supercharger). 3 Bar MAP sensors can measure up to 44.1psi, which translates to 29.7psi boost from a Turbo/supercharger. Q: I will be putting up to 11lb of boost to my …
