When I think domestic performance tuning, I immediately think Hennessey performance. They have just released their renderings of the 2013 Hennessey SRT Viper Venom 700R and their 1000 Twin Turbo. You can expect unbelievable performance from these bad boys. the Venom 700R puts out around 725hp and can get you down the 1/4 mile in about 10.7 sec with a 0-60 time in about 3.2 seconds.
The 1000 Twin turbo is where it gets crazy with the added turbochargers putting down around 1120HP and 1092 Pound feet of torque. This will get you a 0-60 time of 2.7 seconds and a 1/4 mile time of 9.7 seconds. Unbelievable.
Horse power (HP) - 1120HP
Torque (TQ) - 1092
0-60Mph - 9.7 sec
