2016 Dodge Viper ACR racks up lap records

With 645 horsepower and an adjustable spoiler nearly six feet wide, the 2016 Dodge Viper ACR would look at home on the runways of most any airport, air base, or aircraft carrier in the world. But it's not built for the runway. It's built for the race track. And it has positively mastered them one after another. In fact, the new Viper ACR has not only beat the lap times of its own predecessor as it set out to, but took the production-car lap record at 13 tracks across the country. The endeavor started out at the Inde Motorsport Ranch in Arizona, where development engineer Chris "The Wolf" Winkler set a lap time of 1:33.75 on the Configuration 4 track to beat every other street-legal vehicle to ever lap the circuit. Then it was off to Buttonwillow, the MotorSport Ranch (in Cresson, TX), Big Willow, VIR, Grattan, Pittsburg, GingerMan, the Motown Mile, Nelson Ledges, Waterford Hills, and Road Atlanta. And with the new American Club Racer, Dodge took the lap record at each and every one. The journey culminated just days ago at Laguna Seca, where track expert Randy Pobst climbed into the Viper ACR and set a lap time of 1:28.65. That's 5.27 seconds faster than the previous ACR's time, and 1.24 seconds faster than the Porsche 918 Spyder that held the record until now. The sum total is a bragging-rights sheet of lap records set at 13 tracks across these United States. And you don't have to take Dodge's word on that. The records have been certified by the Sports Car Club of America (SCCA), cementing the ACR's place in the record books. Nice work if you can get it, and you can scope it out in the video above and press release below.

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!"

Common Dodge Ram 1500 vs. Chevrolet Silverado breakdowns

These two trucks are famous for their ability to get the job done. Still, even the toughest vehicle can have mechanical problems at some time. What if we match the Dodge Ram 1500 and Chevrolet Silverado head to head? Let's find out more about common repairs for each model. Also, learn some tricks to pay for car repairs. Clunky Steering Both Dodge and the Chevy owners sometimes notice bumping and clunking when steering. This might be more noticeable when driving over bumps. The cause is usually different in each truck though. In the Dodge Ram, clunky steering is more likely due to a defective lower ball joint. Replacement costs around $300 - $400, parts and labor. Clunky Chevy Silverado steering is probably a steering rack failure. This problem appears more often in trucks with over 90,000 miles. Silverado steering rack repair will run you up to $1,000 or more. Starting Woes For the Chevy Silverado with over 130,000 miles, you might notice trouble starting. This problem may appear occasionally at first, but it typically gets worse. Excluding a weak battery, the culprit is usually the starter. Replacement will cost you around $330 - $500. Of the total cost, $90 is for labor only. Now the Dodge Ram might make a ticking sound when starting, especially on models with over 94,500 miles. The noise often disappears after the engine warms up. These symptoms may indicate a broken exhaust manifold. Repair costs range from $800 - $900. Burning Oil & Gas Gauge On The Blink Sometimes, the Dodge Ram burns oil much faster than normal. In models with over 125,000 miles, this often points towards a leaky intake manifold gasket. A knocking sound may also appear with acceleration along with possible engine misfire. The cost to repair is around $200 - $300. The Chevy Silverado has its own surprises, especially when you've filled the gas tank but the gauge still reads low. Or the needle fluctuates widely from low to full while driving. In trucks with over 120,000 miles, it's likely due to a faulty fuel sensor. You might need a full fuel pump replacement, which can cost you up to $820, parts and labor. Water Inside And Poor Heat The Ram 1500 rear window has been known to leak. You might notice the back seat and floor wet after a rainstorm. This is more common in trucks with over 65,000 miles. Resealing the Ram 1500 rear window costs around $150 - $250.
