From the above link pay particular attention to this section here
The general trend is clear.
The pressure is higher where the velocity is lower, and the pressure is lower where the velocity is higher.

Pay particular attention to this part of the above linked page. A turbo is a dynamic compressor by the way.
Dynamic compressors.
Gas enters a centrifugal or axial compressor through a suction nozzle and is directed into the first-stage impeller by a set of guide vanes. The blades push the gas forward and into a diffuser section where the gas velocity is slowed and the kinetic energy transferred from the blades is converted to pressure. In a multistage compressor, the gas encounters another set of guide vanes and the compression step is repeated. If necessary, the gas may pass through a cooling loop between stages.
Gas laws.

Not trying to be an a hole or anything but your arguing against physics here. Why dont you try and explain your theorys to a physics professor or an engineer and see what they say.
Oh and while your at it do some research on nozzels and find out why the velocity increases after the fluid leaves a nozzel.

Some rocket info if your interested also.

care to elaborate?
...and feel free to quote my posts (in particular the one you say had many flaws) to demonstrate my deficiencies.
and while you're at it, explain why spinning the oil pump on your truck faster, in lock-step with engine rpm's, does not cause higher pressure... which any pressure gauge would disagree with.... because higher velocity does not cause higher pressure, right?
we are talking fluid dynamics, no?

Specifically this excerpt.
Oil pressure is caused by the resistance of the oil to flow (viscosity) under the pumping action of the oil pump. With wide oil galleries and low viscosity oil, flow would be rapid and oil pressure low - a very desirable condition for minimizing wear. Conversely, under the same pumping conditions; with narrow oil galleries (by design or by blockage) and high viscosity oil, the oil flow will be slow, oil pressure will be high, hence resulting in less efficient lubrication.
A "good" oil will be one that has viscosity characteristics sufficient to give good hydrodynamic lubrication of the loaded surfaces, yet flows around the engine well to provide a continuous supply of fresh lubricant.
In an extreme case, a very viscous oil would never get to the critical parts to do its lubrication job. Note in this case, that engines do have by-pass valves to prevent excessive oil pressure in case of filter blockage.
You seem to be demonstrating your deficiencies perfeclty well on your own.
That las one should answer your oil pressure question.
