I am, and have been from the Start. To see some Porsche fanatics laugh their butts off because the half-as-expensive GTR is slower here and slower there... It's just rediculous.
The 7:39 reported time was on the standard Bridgestones (RE050's, I believe). This is 10 seconds faster than Porsche's time for the older Turbo on similar tires. With the optional Pilot Sport Cups, the Turbo lapped in 7:38 last year. Subtract 10 seconds from that and the sub-7:30 time is believable. Keep in mind that Porsche doesn't do all-out 'Ring attacks like Nissan, on a closed course. They tend to report times while running with other cars during industry days.Some people still think the new 997 Turbo has lapped under 7:30. It hasn't, it's still at 7:39, so it hasn't even matched the 2008 GTR yet. So it's 13 seconds or 2 years behind, depending on how you look at it.
