But, the 2010 Viper was never run at the 'Ring to show it. They knew they would beat it again. Dodge didn't pay for this trip, a few Viper dealers got together and funded the trip. Just because they could.

Still, to sit here and tell me that a mothballed 2010 "100% stock" ACR Viper came out and ran a full 10 seconds faster than it's previous brethren (a 2008 ACR) is a bit fishy no matter how you look at it....
The only changes on the car were the gearing change that was made on the 2010 model and from what I understand, new tires. That somehow translates into a full 10 second faster time....
The ZR1 meanwhile went and got new tires, and some changes...and only improved it's time about 5 seconds. Roughly the same HP/torque/weight....same exact tires (as far as I can find out)....and yet we have no video proof of it actually happening.
If the Viper was given the same treatment the ZR1 was, I'd expect a faster time than the ZR1, and rightfully so. However, to make that big of a jump with only a minor gearing change and a new set of tires.....
