The extra horses allow the Hennessey Viper to accelerate from 0-150 a full 1.5 seconds quicker (15.5 seconds) than the stock Viper. The brakes have also been modified to reduce the weight of the car (8 lbs per corner)
The upgrade also includes 650R exterior badges and Venom Power floor mats, as well as a serial numbered plaque in the cabin and under the hood, just to let people know that your not driving any ‘ordinary’ Dodge Viper SRT10.
The Venom 650R should have an output close to the Corvette ‘Blue Devil’ proposed for 2009 but until a side by side comparison can be done of the two cars we can only speculate as to how they will compare.
