No particular problem here.... I was just wondering.
When you hit boost (over atmospheric), do the vacuum lines cease to be vacuum lines (perhaps they don't because the tappings are very close to the intake valves)?
Does your VSV close under boost?
Does anyone know at what boost pressure the vacuum lines cease to be a vacuum (i mean, they can't hold out forever, right)
From what i can tell, the vacuum line tappings aren't particularly close to the intake valves, so maybe there's piping inside the throttle body so that the vacuum lines are always below atmospheric pressure?
