Ask me how I know.
The former owner of my car had a friend with a Viper and they would go at it sometimes. He said the same exact thing, essentially he could keep well ahead of the Viper until about 115-120, and then the Viper was quicker above that speed.
I think the 930 aerodynamics really hit a brick wall at that speed.
