Since I've never driven a Viper, I wouldn't know how it handles, although I've heard that it's worse than a tractor. It's tough though, I'll give it that.
I'm just looking at top speed here, since Nurburgring is a very bendy track with over a hundred corners, I'm also looking at cornering speed, breaking, etc.
I'm looking for cars build for driving pleasure, and please let me know what is it that you would find pleasurable about driving it on the Nurburgring, not just a drag strip.
Eg. Rx-8
This car has a tougher than tough engine characterized by it endurance record and high revving, a perfect weight distribution layout for accurate cornering, and to do a great lap-time in it will really need you to be skillful trying to get the engine to stay in it's high-rev band to harness all that acceleration, and I'd imagine the sound of the engine to be incredibly exciting when you do so.
