Dodge Challenger Scat Pack adds power and noise, with a warranty

If you want to go fast, there's certainly nothing wrong with the Dodge Challenger SRT8. With 470 horsepower and 470 pound-feet of torque for 2014, there's certainly not much to complain about. But what if you want something more aftermarket in flavor? There's no shortage of options, but while turning to the tuner world will make your car plenty fast, that extra power won't just shred rear tires, it'll torch your warranty, as well. That's where Dodge's Scat Pack comes in.
With three stages of mods for both the 5.7 and 6.4-liter Hemi V8s Challenger (as well as the 5.7-liter Charger and, soon, the four-pot Dart), the Scat Pack cars give drivers all the power, aggression and noise of a heavily modded aftermarket car while maintaining the piece of mind provided by the Dodge warranty.
Power gets bumped up to 485 horsepower and 475 pound-feet of torque with the 6.4-liter Scat Pack, while the 5.7-liter can provide up to 58 hp and 47 lb-ft of torque to add to the stock engine's 375 horsepower and 410 pound-feet. It's the latter engine that can really get some work done, with upgrades ranging from the mundane - intake and exhaust - to the racy, like the ported heads and high-flow headers.

NHTSA investigating power modules on Chrysler Group SUVs and minivans

The Center for Auto Safety is officially petitioning the National Highway Traffic Safety Administration to begin scrutinizing alleged problems with the totally integrated power module (TIPM) on about 24 Chrysler Group SUVs and minivans. The advocacy group claims that the part's failure can cause affected vehicles to stall or not start at all. NHTSA is still looking into the accusations and deciding whether a full investigation is actually warranted.
The CAS petition claims at least 70 TIPM failures, but according to NHTSA, six of the complaints are for models that don't have the modules. In 34 of the reported cases, the vehicles refused to start, and in 17 of them the engine stalled. There were also two allegations of smoke and one of a fire. However, none of these affected airbag deployment or resulted in a crash.
This petition isn't the first TIPM-related problem for Chrysler Group. A recent report in the New York Times alleged that it found 240 complaints potentially related to the issue on NHTSA's website alone. In September, the automaker also recalled 230,760 examples worldwide (188,723 in the US) of the 2011 Jeep Grand Cherokee and Dodge Durango replace the fuel pump relay circuit inside of the TIPM-7 with one external to the unit. The original part could allegedly cause the models to stall without warning. Even earlier, the company also recalled about 80,000 examples of the Jeep Wrangler and Dodge Nitro in 2007 to have the module reprogrammed.

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.
