A couple of months ago in the Drive magazine, there was an interview of the famous Walter Rerl ex Rally car champion and test pilot of Porsche.
Answering a question about the times of the GT-Rat the ring he said: I haven't drove yet a GT-R so I cannot comment on it. The only thing I can say is that I was driving a Ferrari Scuderia in the ring and while I was in the big straight I saw in my mirror the GT-R at a distance of 120 meters behind me. After 500 meters the GT-R was exactly behind the Ferrari. Scuderia as you know has 510PS and weights 1250 kg while the GT-R weights 1740kg and has a power of 480PS. As you understand it is not possible with such power to weight ratio to be as fast as that, and claim also those times at the ring.
In order for the GT-R to be that fast has to have an increase in the boost of the turbo having a power of 600PS. Only this way can be that fast...
