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.

Hennessey's Dodge Challenger Hellcat cranks out 1,032 hp

Enthusiasts know the Dodge Challenger Hellcat produces 707 horsepower. It's one of the modern muscle-car era's iconic numbers. But for some, that's not enough. Enter Hennessey Performance. The Texas tuners loaded the Hellcat with a twin-turbocharger that works with Dodge's supercharger to boost output to 1,032 hp and 987 pound-feet of torque. Yes, that's an engine dyno rating, not at the rear wheels, but still! It's a little more complicated than a bolt-on booster. Called the HPE1000, the turbo kit has stainless steel headers and down pipes, billet aluminum compressor wheels, and a high-flow air system. There's also an an improved fuel pump, and the engine and chassis are specially calibrated. You also get numbered plaques signed by John Hennessey himself and the engine tech who builds your mill. All of this helps get your Hellcat to 60 miles per hour in 2.7 seconds, and it can do the quarter mile in 9.9 seconds at 142 mph. The Hellcat and it's 6.2-liter blown Hemi V8 are not for the faint of heart. Hennessey makes this Dodge downright demonic.

Tesla Model S P85D shows 707-hp Dodge Challenger Hellcat how to drag race

Street Car Drags hosted a bang-up event at the Palm Beach International Raceway last weekend, with a list of massive horsepower ICE cars going up against one another and a trio of Tesla Model S P85Ds. One of those duels pitted the 691-horsepower Tesla against a 707-horsepower Dodge Challenger SRT Hellcat, and the result was an old-school beatdown and a world record for electric cars. The Model S P85D ran the quarter in 11.6 seconds at 114.6 miles per hour, the new mark for BEVs at the drag strip. Proving its pace, it ran three more times in 11.69, 11.72 and 11.76 seconds. It got from the start line to 60 miles per hour in 3.1 seconds. The Hellcat, well, it wasn't a race, really. It was the Hellcat's driver's first time at a drag strip and his first time trying to launch it, so after an excellent burnout ahead of the lights, he rolled to the line, almost jumped the start, balked at the real start and spun his tires for the first 100 feet down the strip. The theory is that he overheated his street tires during that burnout, and the resulting greasy rubber did what greasy rubber does. By the time he got to the other end 17.46 seconds later the Tesla driver had showered and was enjoying a funnel cake. When things go right, though, Dodge estimates the Hellcat will do 11.2-second runs on street tires and it has been clocked at 10.85 seconds at 126.18 mph on street-legal drag radials. There's video of the not-quite-a-race above, and Drag Times says there'll be a rematch between the two in a couple of weeks.
