Okay, we'll try this.

Let's say you hit the throttle, and go to WOT from a standstill. At 2000 RPM, you're at WOT. When you hit redline, you're still at WOT. Is the boost the same? Of course not. If you put the pedal to the floor from a standstill, are you going to be producing max boost at 2000 RPM, even if your foot is on the floor? Of course not.

The amount of boost produced is dependant upon how fast the turbine is spinning, which is driven by exhaust gasses- NOT the throttle pedal, throttle body, etc, etc.

Also, by the WOT=full boost theory, Boosted isn't running at WOT until 3rd or 4th gear. Strange drag race strategy, IMO. This also brings up rotational inertia and how it isn't a concept reserved for rolling stock, but that's another thread. For more info on that, go to "How to Figure Out..." a great sticky, BTW- good job, Boosted.

Indirectly, yes, obviously putting the pedal to the floor will rev the engine higher, thus producing more exhaust gasses, which will in turn exit the engine, drive the turbine, and produce boost. However, your earlier post clearly stated that boost was a direct product of how far the throttle pedal is depressed, which is far from accurate.
