Hennessey SRT Viper Venom to offer 725-hp and 1,120-hp upgrade

Just behind the release of their take on the CTS-V, Hennessey is back at it again with the release of two high-performance packages for the 2013 SRT Viper. Few tuning houses craft models that are able to rival that of Hennessey’s, and the company lives up to its reputation once again with both a 725hp and a 1,120hp version of the already ridiculous Viper.

The Hennessey Venom 700R is offered up on both the Viper and the Viper GTS, and gets more then its fair share of performance upgrades. To highlight some of the enhancements, the package includes high-flow cylinder heads and catalytic converters, engine management calibration, a stainless steel 3-inch exhaust and a K&N air filter. Together, the mods produce 725hp at 6,400 rpm and 695 lb-ft of torque at 4,400 rpm, allowing for a super-quick 3.1 second 0-60mph time, a 10.7 second ¼ mile run and a 21 mph top speed.

Plenty of exterior options are also available, such as carbon fiber parts for the front splitter, rear lip spoiler and canards, along with a wheel selection, 5 point racing harnesses and a double adjustable coilover suspension system. Interior mods are available, but less extensive.

The second package that Hennessey offers is the Venom 1000 Twin Turbo engine upgrade, that provides an awesome 1,120hp at 6,200 rpm and 1,092 lb-ft of torque at 4,200 rpm. Hennessey achieves this with mods that include forged aluminum pistons, a front-mounted air-to-air intercooler, two precision ball bearing turbochargers, and plenty of others. Combined, the tune enables a 0-60 mph time of a mere 2.7 seconds and a sick 9.7-second quarter mile time.

Optional upgrades remain the same for both versions.

I will happily applaud Hennessey once again for an extremely well executed package, as they are one of the few tuning houses that can work a car like the Viper the right way. Be sure to hit the jump to check out the full list of modifications for each of the models.
