ok, I finally have a minute to think about how to explain this. Here goes.
Don,
let me start with this statement, Boost does not make power. In reality, all the boost pressure is, is a measurement of the resistance to the flow from the turbocharger into the cylinder. The reason you get more power when you raise the boost pressure, is because you are flowing more air into the engine. This is also partly why, after a certain point increasing boost pressure will give less gain for each psi, the engine can only flow so much air, and you get to a point of diminishing returns.
I will go on to say, a turbo does NOT make boost. A turbo pumps air, and in order for boost pressure to exist, that air must be pumped against some restriction. The more restriction, the more boost pressure. This is why, for a given amount of airflow, an SVT contour will have less boost pressure than a regular contour will. This is also why, for a given boost pressure (regulated by a boost pressure referenced wastegate) an SVT contour will flow more air than a regular contour.
Try this, take a stock SVO, and measure the airflow going into it at a given amount of boost (and a particular rpm), then go get an Esslinger head or somehting like that, with improved ports and whatnot and put it on the car. w/ no other changes, I gurantee that the new head, at the same boost pressure and rpm will be flowing a lot more air. or you can take the wastegate setting and play with it until the two airflow measurements are the same, and then look at the boost guage, and it will be noticably less than the stock head.
cfm of a turbo is not related to the engine flow. it is dependent on the turbo itself.
This is just plain wrong. Where do you think the airflow from the turbo goes? (ignoring a blow-off or bypass valve)
You know what, I just completely re-read your post, and you are close, but quite mixed up. It would take more time than I have now to cover it all. I guess I will have to come back to this.
