Toby, thanks for the detailed explanation, and it basically supports with objective measurements the hypothesis i had in mind.  the key factors being 1) quicker spool / response due to the smaller turbos; 2) faster shifting leading to virtually "full-boost" shifts.  and probably also shorter gearing, with the PDK having 7 speeds vs the GT2's 6.

the videos were not intended to be a scientific test by any means, but just for fun, and to document somewhat "real world" (or "real" for THIS part of the world) conditions.  there are optimal situations where the cars may perform better-- as the video showed for instance, starting from approx 130kmh, the Z06 actually beat the PDK by half a car length or so.  but in most other situations-- i.e., from very low speeds, or in poor traction situations, or where you just don't have the room to run to 250kmh and beyond, etc-- the new PDK Turbo is all-round the complete package.

obviously things change on the track, but that is much harder to "test" and document on these videos, as driver skill is at least as important as the car itself...
