Hennessey is famous for extracting a lot of horsepower from engines with the use/optimization of forced induction. Their kits range from light to hardcore and the Venom 700R pack for the SRT Viper is on the less complex end of the scale.
There’s no turbo or supercharger kit in sight, and the 8.4-liter V10 engine is made to produce 705 hp (up from 640hp) with the use of old fashioned tuning techniques.
On the list of mods we have high-flow cylinder heads, custom tube headers and 3-inch exhaust, high-flow cat and a K&N performance air filter. Torque gets a boost too, up from 600 to 695 lb-ft (813 to 942 Nm) – this is an increase you’ll definitely feel, and it goes to show that the large ten-cylinder engine has yet more to give, even without affecting its response and signature exhaust noise by fitting it with twin turbos.
The extra power sends the Viper to 60 mph (96km/h) in 3.1 seconds, while the quarter-mile sprint is dispatched in 10.7 seconds. Top speed is rated at 216 mph, or 345 km/h, if anybody dares go that fast in it, that is, as it’s reportedly not the easiest thing in the world to control, and it can’t get easier the faster you go.
Hennessey also offers a slew of optional carbon fiber parts, lighter wheels, 5-point racing harnesses, adjustable suspension, differential cooler and even a fire extinguisher. There’s plenty of badging thrown in for free, as well, though, to be fair, having numbered plaques all over the car’s interior and exterior is a bit on the excessive hey-look-at-me side
