bluelines:
Now we just need the torque curve which should be high, wide and flat Smiley The new intake system with the switchable flaps is hopefully handling this nicely for low vs high rpm (just like the 997.2 X51 package).

Don't expect better low-end torque.  The Carrera S already has a variable intake tract to make max torque across the rev range (started 17 years ago in the 993 Varioram).

The listed modifications are required to make the extra 30hp at the top of the rev range (7,500rpm).  To make any noticeable difference to torque in the lower revs, you need to add discplacement or forced induction (turbo or supercharging).

Actually, if the X51 makes the same torque as the Carrera S but 150rpm higher, then it has slightly worse low-end torque by definition (less torque than the Carrera S' at 5,600rpm, but more torque (HP) at 7,500rpm).  So, the shape of the X51 torque curve is necessarily peakier...
