I have owned and raced the Srt and still own the Z06 and the GT as well as several other cars. I am pretty well known in the Viper community running My Supercharged Viper, the first successful one by the way, done by Jason Heffner and I have run several of Jasons customers cars and some of Jasons First Twin Turbo cars for him as well. I have run at several of the Viper shootouts in Englishtown and Beech Bend in Bowling Green. I ran low 10's on street tires at Beech Bend in Gary Almonds Supercharged Rt/10 which was the fastest time on street tires and I think I am a pretty competant driver, as I am sure most guys that know me or have raced with me will agree. The SRT in as delivered condition usually runs low 12's at about 118 with a good driver and I think if you call Jason he will tell you thats what they run in Bradenton when they take stockers out with a good driver. I have seen and driven many and have never seen a stock Srt go 11's although I am sure there are a few guys that have made that perfect pass and put one in the 11's but I have never seen one. On the other hand I have seen many stock GTS and Gen 2 vipers go 11's and I think in the viper community most guys will tell you the gts will out quarter mile the Srt, maybe the 19" wheels and tall tires and gear ratio with 3.07's hamper its 1/4 mile time on the SRT? Now for the Z06 my first day out on my first pass the car went 11.4 at 127 and lived in the 11.3's all day at 128 mph with a best of 11.2 at 129 to date, and that is as delivered 100% bone stock, with tires would easily go 10's. My Gt went 11.5 at 127 on its best pass as delivered. There have been no quartermile tests run on the 2008viper so everything is speculation, but 3 tenths for the current Viper and the new Z06? That's just fantasy, not even in the same league, everybodys got a buddy who's car ran this or that, I can speak from first hand experience hands on both cars and that why I say I will believe it when I see it or experience it!
