I don't know if McLaren plan to come forward and show the world what they have done - earlier they suggested they would not, but now they aren't being quite as tight-lipped over the result as I expected them to be by telling a journalist who was sure to repeat what he heard.
On a side note, sorry to 
but does anyone have a diagram of the car in respect to where all the vents, ducts & scoops go? More specifically, where does the scoop on the roof and doors lead to?
Thanks...

Yes, you may assume that to be correct on the time range. This time was obtained running a complete lap and is not a compilation of sector times.

Roof scoop splits at the entry point and channels air through the Monocage and into the airboxes on each side. The door scoops below the window feed air to the side mounted radiators.

McLaren's tire partner in both Formula One and their road car business is Pirelli. Much to the dismay of some owners there isn't even a factory approved Michelin tire you can fit to the 12C, for instance.
Pirelli developed a special version of their P-Zero Corsa tire specific for the production McLaren P1 in order to maximize grip and manage things heat and sidewall deflection under the heavy downforce load produced by the car at speed. It was these tires that were fitted to the P1 for its laps of the Nurburgring that mattered here.
More info on their relationship expressed here by the Sales Director for P1, Marcus Korbach, and their lead on the program at Pirelli, Stefano Bizzi:
And here - some details on the tire:
If you care to read more, here's a Pirelli press release that was republished after the Geneva show:
Pirelli Develops Bespoke Tyres To Power The 903 HP Of The P1
Oh, and before I forget... I wouldn't be too skeptical of the claimed lap time. They are definitely in the range specified.

And here - some details on the tire:
McLaren P1, which uses PZero Corsas 245/35ZR19 front and 315/30ZR20 rear.
Pirelli said the tires for this two-seat, mid-engined car are designed to deliver maximum stability and handling for a car with a top speed of 223 mph.
Among the specific features of the Corsas for the P1 are:
- Asymmetric profile on the front tires to optimize aerodynamic downforce. The asymmetric design allows the tire to remain sufficiently rigid even when subjected to different weight transfers, Pirelli said.
- Asymmetric bead design on the rear tires to help withstand lateral forces of up to 2g under acceleration and through corners.
- Innovative compounds processed with Pirelli's "ground-breaking" mixing processes to improve stability and resistance to stress.
Pirelli makes the various PZero models at its plant in Settimo Torinese, near Turin, which uses the firm's "Next Mirs" robotic tire manufacturing technology
