I suppose it is 473 HP SAE for the US and 480 HP DIN for Germany, this is where the confusion comes from.
But still...there are some questions to ask: if the boost pressure increases by 0.2 bar for 10 seconds, why doesn't the power increase and only the torque? Which brings me back to my theory that MAXIMUM power isn't increased but power at certain rev ranges IS INCREASED by at least 30-40 HP. Meaning: if the engine has lets say a 400 HP output at 4000 rpm, it increased to 440 HP at the same rev range. Now this "trick" should actually make the 997 Turbo the hell of a perfomer on the track since it adds more horses and torque at lower rev figures.

With information from this article that we know, and interpolating some values, it's conceivable that the 480 HP is due to overboost and the 473 is without. Although this article at least states that "Power remains the same". If the former is not the case, it can be argued that the HP increase is pretty insignificant with the overboost (+7 HP)

Porsche has known for almost two years what 997 TT competition can do. It is safe to assume the 997TT will exceed their competition performance. If 473hp will do the job, why give it with 500hp when you can charge an arm and leg for the extra hp?

The 997 TT will beat the 430 and Galardo in performance tests. To me it will be of no consequence.

A really nice surprise is that it is 22mm wider than the C4S!!
Yeah, that is a nice surprise.

Yeah, that is a nice surprise.
Yeh, that'll even surprise Porsche.
The cars' makers think that the Turbo and C4S are the same width, and that both are 22mm wider than the narrow body C2 models.

But isn't the C4 wider than the C2 by 44mm?
