The reason people (such as myself) are pointing to WOT is that the throttle plate is a restriction in the intake stream, and as long as the throttle is not completely open, the engine "wastes" some of it's energy in creating a vacuum, rather than turning freely.
A diesel, for example, doesn't have a throttle plate and is throttled strictly by fuel.
