2015 Ford Mustang EcoBoost already hitting 12-second quarters

The arrival of a new Ford Mustang means many things to many people, but not least of them is drag racers. The pony car has always been a mainstay of the drag strip, and the Ford Racing team aims to carry that reputation forward with this latest generation. So it cooked up a few basic modifications on three new 'Stangs and headed to the strips at US 131 and Milan Dragway to see what they could coax out of 'em.
Impressively, the 5.0-liter V8 Mustang GT with a few modifications (but no forced induction) managed to clock a quarter-mile time of 11.77 seconds. Another Mustang GT fitted with a supercharger clocked a blistering 10.97 seconds. But just as intriguing was the modified EcoBoost model that, with only four cylinders and 2.3 liters of displacement, still passed the gates in just 12.56 seconds - nearly half a second better than expected. This with modification limited to a new subframe, half-shaft, drive shaft loops, exhaust, engine calibration, slicks, roll cage and bucket seat. Well done, boys.

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!"

Jay Leno drives postcard-perfect '32 Ford Highboy Roadster

At the turn of the century, it was arguably the Honda Civic that best defined inexpensive performance tuning, and in the '50s it was the Tri-5 Chevys. One of the earliest platforms to gain a huge following among young people looking for a cheap way to go fast was the classic '32 Ford Highboy Roadster. This week, Jay Leno's Garage looks at one of the very first vehicles that defined the look of the hot rod heyday.
This '32 Ford was built in the '40s and graced the cover of the fourth issue of Hot Rod Magazine back in 1948. All of the hot rods that you see shining at car shows today owe a serious debt of gratitude to this roadster. It bears all of the cues that define the look, including a notched frame and hidden door hinges. Under the three-piece hood is a flathead V8 boasting all sorts of period modifications, including copper cylinder heads. It was seriously fast in its era too, and proved it by reaching 112.21 miles per hour on a dry lakebed in 1947.
These days, this hot rod is on display at the Petersen Automotive Museum. Although, if you can't make it to California to see it, the United States Postal Service is celebrating this Ford with one of its two hot rod Forever stamps. Like Jay says in the video, in terms of hot rodding, "it all comes back to this." Check out the video to learn more about this rolling piece of tuning history.
