Dodge Viper to out-Hell the Hellcat with supercharged V10?

The Viper wouldn't be the Viper if it wasn't the most powerful model under the Chrysler umbrella. But with the arrival of the Hellcat engine in the Dodge Charger and Challenger, the Viper has fallen behind in the bragging rights department: where the new supercharged V8 produces 707 horsepower and 650 pound-feet of torque, the naturally aspirated V10 offers "only" 640 hp and 600 lb-ft - gargantuan output figures by almost any other standard, but crucially behind on the SRT power scale. Conner Avenue is going to have to do something about that.
Although the Hellcat's engine reportedly won't fit under the Viper's hood, SRT is now rumored to have another trick up its sleeve: supercharge the existing V10. According to the Pentastar performance enthusiasts at allpar.com, Chrysler has already taken delivery of the first such prototype engines so that it can begin the process of fitting it into an upgraded Viper.
The spooled ten-pot is tipped to produce around 800 hp and 650 lb-ft of torque. More than that and the Viper's drivetrain, chassis and bodywork would have to be substantially reworked. Though beefier transmissions are available, fitting them would reportedly set off a domino-game of changes required to handle the added torque. Which may be something Chrysler would be prepared to do for the next-generation model, but in the meantime, 800 hp could prove enough to put the Viper back atop the Mopar performance ladder where it belongs, and give it an edge against the new Corvette Z06 to rekindle sales.

Watch dual-engined Dodge SRT4 do a FWD burnout, a RWD burnout, then AWD launch

There's something fantastically insane about racers who go out on their own and build something unique. Just take this crazy video from last year of a twin-engine Dodge SRT4 at a drag strip that can burn the rubber at either end – or both ends – at a moment's notice. With tires sticking out way past the fenders, a massive cooling system at the front and no back window to speak of, this Dodge is clearly meant solely for speed. Though it's real party trick is being able to spin the front or rear wheels independently. The setup makes for three quite showy burnouts. When it came time to actually get down the track, things got somewhat awkward. Like other twin-engine creations we've seen, the separate powertrains make for some odd sounds and a weird look launching down the strip. Still, there's no doubt that the engineering behind this Frankenstein is very impressive. Scroll down to see this monster in action and another of it in a very mismatched race last year.

Dodge Scat Pack for 5.7L Hemi V8 detailed, priced

Dodge revived the Scat Pack name back in November at the 2013 SEMA show. At the time, though, we were short of details on forthcoming upgrade packages, which were destined to add some oomph to the Challenger, Charger and Dart. We're still waiting to hear about the upgrades to the Dart's 2.4-liter four-pot, but Dodge has gone ahead and released the details on the upgrades to the 5.7-liter Hemi V8 in the Challenger and Charger R/T.
As we detailed in our original post, three different Scat Packs will be available that will allow customers to upgrade their cars without voiding the warranties. Starting with the $2,195 Stage 1 kit, owners will net an extra 18 horsepower and 18 pound-feet of torque thanks to a Mopar-branded cold-air intake, exhaust and ECU ref lash. Stage 1 is also the only package that could be installed outside of a Chrysler-authorized service center without voiding the warranty (a mechanically competent owner could even do it at home, we're told by Dodge). Stage 2 builds on the entry level Scat Pack, and adds performance camshaft kit, which boosts output over the stock 5.7 by up to 30 hp for $1,895. As with the Stage 1, the ECU is tweaked.
For those that want to go whole hog, they can add the Stage 3 for $4,995. The top-tier gets quite serious, adding CNC-ported cylinder heads, as well as high-flow headers and cats. Output over stock is 58 hp and 47 lb-ft of torque. Each kit comes with a pair of badges, just in case owners want a bit of visual flair.
