You completely misunderstood my post and bypassed my main point. I never doubted that all the extra power would yield better times. I don't mean to nitpick, but your semantics made it confusing. From what I understand from your post that I quoted, it seems like you're saying that the 600 whp GT500 did the 1.456-second 0-60 ft time, and the 800 whp GT500 could reach the 1.3s. Maybe, but you didn't say that, all you said originally was "with a harder launch," you didn't say anything about a different setup, whether it's something as minor as adding race fuel or something along the lines of additional bolt-ons. And I think it's pretty fucking obvious that mods will make your car faster, whether it's 10 or 200 extra whp.
And after your rephrasing, I agree that it isn't leapfrogging, but the original issue was that you made it seem like the GT500 that did the 1.456-second time could do 1.3 with the exact same setup, which would definitely be leapfrogging. When I said "leapfrogging a car's limits over and over and over again," I was referring to a situation where the car stays in the same state of tune throughout the tests--maybe not necessarily stock form, but the same setup--and higher and higher and higher claims are made. And by that, this is what I mean. Take this scenario: let's say you have a broken-in stock Ferrari F430. One magazine does 0-60 mph in 3.5, one magazine does it in 3.7, and a couple seasoned Ferrari owners pull off a 3.5 and a 3.6. You can't automatically assume that with a bit more pushing, the car might do 3.4 as-is. Saying that it could hit 3.4 would sort of be leapfrogging, seeing how the magazines and a couple online drivers have been mirroring similar results with the car hitting 3.5. But let's say Michael Shumaker gets behind the wheel and magically pulls off a 3.4 in the same car. Then you say that maybe a 3.3 is possible. That would definitely be leapfrogging. Do you see what I'm trying to say? In a specific state of tune, every car has its absolute limits. And while it might be possible to nudge a car's performance just a smidgen further, it has to stop somewhere. And I think that is my main counterargument to most of the stuff you've posted not just recently but in the past couple weeks--the whole "people are doing [insert time] in the [insert acceleration measurement], but with a good driver (as if the first drivers weren't) you could probably do [insert significantly lower time, considering it's the same setup]" argument.
As I usually say, I hope I don't sound anti-GT500 or anti-C.R.Y--I am a fan of the GT500 (although I don't think it's for me) and I enjoy going back-and-forth on certain arguments, since it's certainly more thought-provoking than this specific forum being dead. But let the car go! Yes it's fast, yes it's faster with mods, we know, but I think the updates on the GT500's capabilities, while well-appreciated, might be more appropriate under the same thread (perhaps the original "Thoughts on the 2007 Shelby GT500" thread?) rather than starting up a new one about the same car when a new product comes out for it or if somebody manages to knock off a tenth from their times. Just a friendly suggestion.
