For about $150,000 you can customize your Viper to go 255 miles per hour, or 4 feet in a 100th of a second!!
Look for the Hennessey Viper. Hennessey have a Twin TurboViper with 1000hp which can cover a mile faster than a Veyron and it reaches 220mph at the end of the mile. Basically, it will be dead fast.
