My Lord this thread has gotten a lot more... uhh... whatever, since that time came out.
So, one guy goes out, nails a lap in partially wet conditions... in November (take note, as Greycap says, track temperature is a big issue... a
hot partially wet track is much different from a cold and greasy partially wet track), and then declares with finality what the car can and can't do? For me, a cold, semi-wet time would probably be at least 10 seconds longer than a time on warm Nurb...
I've done track work in cold conditions... and man, it sucks. No grip, hard to get heat into the tires, braking changes, cornering changes, everything does. In fact, I looked at the first half of your post and thought... you're celebrating because it proves 7:38 is possible?
forza2.0, I don't think you're owed that apology just yet... you've been caught in too many contradictory statements and assertions about tires and times and PWR, please, just let it rest...
And, once and for all... semi-slick, semi-race... come
on... extreme performance or ultra-high performance tires are light-years from DOT-legal road tires... I've been riding on Advan Neovas for the past two years. They have much more lateral grip than the GSD3s, treadwear somewhere in the nether region of hell, and they're not the most practical of tires, (they lose grip when cold, but are actually quite forgiving in the wet... the only problem UHPs and EHPs have in the wet is the lack of hydroplaning resistance) but they're a far cry from DOT-legal autocross tires... I've gotten mine to last three or four events plus 30,000 kms (and I still keep my worn set for future events)... while a DOT-legal racing tire would be worn to uselessness after just a few thousand kays on the road... (hey, an autocrosser I know wore his A038s... or 32s, whatever... down in one event, because he commuted 300 kms home on them afterwards)... which is why I passed up on the even faster A048s... I didn't fancy changing tires twice as fast as I already do.
One magazine calls them semi-race. The rest of the civilized world calls them UHP street tires. I'd believe the rest of the world... because calling them semi-race puts DOT-legal racing tires in a kind of no-man's land...

As for the times themselves... again... still nothing conclusive... depending on how bad conditions were when they did the test of the stock car, that would mean an equivalent time in Nissan's claimed conditions of between 7:40 and 7:46. A 7:38 might be possible if the pre-production car was running light or sans some emissions equipment, but we'll never know the car's true potential until someone does a dry lap in good weather... which would be sometime in the middle of next year.
But I do believe a 7:40 flat is quite possible on a dry, warm day, given that time.
