While pressure does tend to equalize, the intake tract of an engine is not a sealed system. It has a turbo compressor forcing air in at one end, a number of parts of varying degrees of restriction in the middle, and an engine eating air at the other end. In other words, there is a bunch of air rushing through the system, and the result is different pressures at various points along the path.

Think about how a venturi works guys. There is reduced air pressure at the venturi throat, which also causes a tempurature decrease. Typical carb setup. Bernoulli's principle: as the velocity of air increases, its internal pressure decreases.

To prove that physics will win agian, I will put a few more pressure sensor throughout my piping in the morning. All of them will read the same at any given time. It is impossible to have a higher or lower pressure than any other place in a sealed system. For there to be 10 psi in the compressor, there has to be 10 psi in the manifold and TB and piping and intercooler. It will equal itself out. Thats what pressure likes to do
That's not physics buddy. You need to read a few books...

Aerodynamics is basically physics though now that i think of it although it's not typical physics. Damn, I wish I was a little more thorough. ******* short attention span...

What everyone in this thread has said is right in their own context.
Pressure in a closed system at 10 psi is 10 psi everywhere. Correct if we are talking about steady state situations. If you were to pressurize the system at 10 psi and hold this pressure for an X amount of time the pressure on measured at the compressor and throttle body would be 10 psi.
It is when the system is dynamic of in it's inital state that is when you see a closed system having different pressures at different locations. Upon initial pressurization in a system with a restriction the location prior to the restriction will experience a higher pressure then on the other side.
This is not really physics, it is introductory to fluid dynamics.
Now the questino is does this intercooler cause that big of a restriction.
