Chrysler readying Hellcat V8 with Viper-like power

A monstrous supercharged V8 engine could be in store for Chrysler and SRT products, if recent rumors are to be believed. Allpar is reporting that the forced-induction V8 - Chrysler's first, if this goes down - could make its debut this summer.
The story goes that the Hellcat would be based on a 6.2-liter Hemi engine, rather than on the existing 5.7- or 6.4-liter versions of the company's vaunted mill. In any case, the general consensus is that the motor will have gobs of power. Modest estimates call for between 500 to 570 horsepower, with some outliers predicting a figure as high as 600 hp. That figure would put the output would place the Hellcat awfully close to that of the 640-hp V10 in the SRT Viper, too. Allpar contends that a slightly lower powered version would allow Chrysler to keep costs below that of the more powerful Ford Shelby GT500, which might be a sweet spot.
The Hellcat could debut in a number of SRT products. SRT versions of the Charger, Challenger and 300 are all up for grabs, as is the rumored SRT Barracuda.

Mopar teases a big Hemi crate engine for SEMA

Mopar has released a new video teaser hinting at the release of a large and powerful crate Hemi engine at SEMA later this month in Las Vegas. The video functions like a lesson on symbolism in an English lit class. It opens with smoke and settles on a pair of backlit, large-clawed paw prints that look to be feline in origin. Then we hear earth-shaking pounding sounds of something larger than the paw prints that stomps over them. Then cue an overhead shot of what looks to be a vintage-model Dodge Charger and its growly Hemi engine entering the frame and then gunning the engine. Mopar already offers three crate Hemi V8 engines, topped by the 6.2-liter supercharged Hellcat, good for 707 horsepower and 650 pound-feet of torque, found in the Dodge Charger SRT Hellcat and marketed for pre-1976 classic muscle cars. So promising that "Something big is coming" is really saying something. Could it be a crate version of the 808-hp Hemi 6.2 that was found in the Dodge Demon, which was rated at 840 hp on racing fuel? Or is it something different? Curiously, Mopar says its reveal is planned for Tuesday, Oct. 30 at the odd time of 4:26 p.m. Could that time be a reference to the 426 Hemi — and specifically the Generation III 426 Hemi "Elephant" that Chrysler made several years ago? That technically qualifies as "bigger," and it would also align with both the muscle car-era Charger and round, earth-shaking footprints shown in the video. Time will prove whether we were right.

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.
