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.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

Weekly Recap: FCA hit with record fine as NHTSA crackdown continues

The National Highway Traffic Safety Administration slapped Fiat Chrysler Automobiles with a record fine this week that could reach $105 million. The punishment comes after NHTSA found problems with the automaker's execution of 23 recalls that affect more than 11 million vehicles. The consent agreement, announced Sunday, calls for FCA to pay a $70-million cash fine and requires the company to spend at least $20 million over a three-year period on industry outreach programs and to beef up old recall campaigns. Failure to comply will result in another $15-million fine. FCA also agreed to federal oversight, which includes an independent monitor to oversee the company's recalls. The $70-million cash fine equals a penalty NHTSA levied on Honda in January. "Fiat Chrysler's pattern of poor performance put millions of its customers and the driving public at risk," NHTSA administrator Mark Rosekind said in a statement. "This action will provide relief to owners of defective vehicles, will help improve recall performance throughout the auto industry, and gives Fiat Chrysler the opportunity to embrace a proactive safety culture." FCA called the deal a "consensual resolution," but admitted that it "failed to timely provide an effective remedy" during certain recalls. "We are intent on rebuilding our relationship with NHTSA and we embrace the role of public safety advocate," the company said in a statement. The announcement kicked off a busy week for the automaker. NHTSA agreed FCA did not need to recall 4.7 million vehicles after an investigation failed to find defects with a power module used in some Jeep, Dodge, and Ram vehicles. A Georgia judge also reduced a civil verdict involving a death in a Jeep Grand Cherokee crash. Amid all of that, the company reported net profit of about 333 million euros, or $364 million in the second quarter on Thursday. OTHER NEWS & NOTES FCA ramps up Hellcat production Despite a decidedly legal and financial week for FCA, there was still time for the performance side of the business to briefly grab the spotlight. The automaker is more than doubling its production of the Dodge Challenger and Charger SRT Hellcats in response to strong demand. The order bank opens the second week of August and production begins in September. FCA will finish up its scheduled 2015 model-year Hellcat builds, and cancel any "unscheduled" versions, though customers will get discounted pricing for 2016.
