Hennessey releases renderings, details of new Viper-based Venom 700R, 1000 Twin Turbo

Hennessey Performance is known for taking fast cars and making them even faster. Just imagining what the Texas-based tuner can do with the 2013 SRT Viper is pretty exciting, and it seems like we won't have to wait much longer as Hennessey has released renderings and specs for the new Venom 700R and the Venom 1000 Twin Turbo. After purchasing a 2013 Viper or a Viper GTS (for $97,395 and $120,395, respectively), those looking to add a little venom to their snake can have the car shipped to Texas for the upgrades; Hennessey has not released pricing for either of its new Venom Viper models.

Stepping up from the base 640 horsepower and 600 pound-feet of torque that the SRT Viper delivers, the Venom 700R gets freer-flowing intake and exhaust, helping to increase the 8.4-liter V10's output up to 725 horses and 695 lb.-ft. of twist. This is done with reworked cylinder heads and exhaust system as well as a retuned engine computer; all with a three-year/36,000-mile warranty. On the 700R, Hennessey claims a 0-60 time of 3.1 second, a quarter-mile time of 10.7 seconds at 134 miles per hour, and a top speed of 216 mph.

If that isn't enough power and speed for you, Hennessey can dig even deeper into the engine and toss on a couple of turbochargers to create the Venom 1000 Twin Turbo. Hennessey says this engine will be rated at 1,120 hp and 1,092 lb.-ft. of torque which can get this car to 60 mph in just 2.7 seconds and through the quarter mile in 9.7 seconds at 152 mph. To accommodate such massive output, almost everything about the Viper's engine has to be upgraded except for the block and crankshaft.

It isn't clear if these stated performance and engine specs are preliminary numbers or actual tested numbers, but they're impressive nonetheless. Options for both cars range from aero upgrades to must-have racing equipment like a rollbar and five-point harnesses.

Not sure I buy the "re-tuned engine computer" part.

Mopar (chrysler) PCM's have a rotating military-style encryption from 2011 on. There are no plans to release the break-in codes any time soon. I know because I want a programmer for my Ram and it simply does not exist. The mopar community is up in arms about it, specifically the Ram and the SRT-anything owners.

Going from 640-725hp is not likely to be worth the extra 30 grand they will charge. That 1000 looks good though, if they can tune it.
