It’s been almost a decade since Roush Performance unleashed its last P-51 Mustang. The wait has been well worth it as the tuner’s latest P-51 Mustang, unveiled on Friday, is the most powerful yet. Heck, it’s the most powerful road car Roush has ever launched. The car was previewed...

Alcon likes big brake kits, and it cannot lie. That's why it's created such a kit for the Ford F-150 Raptor. This is a big rig that manages to haul itself down from speed nicely, but there's always room for improvement. That's what the Alcon brake kit provides. If you upgrade to this kit, you'll...

In our continuing exploration of the world of hillclimb race cars we present a new mighty, maniacal machine for your enjoyment. This time around we're working with a Lotus Elise. This is a car built on the idea of added lightness, but this one also has a V-8 engine. This particular V-8 isn't a...

There are few Japanese engines that gain the recognition Toyota's 2JZ inline-6 does. Not only was this 1990s-era Toyota Supra engine over-engineered for the time, it's also incredibly reliable and can handle oodles of power when the aftermarket touches it. Does it have any business in a Jeep...

Hennessey Performance Engineering unveiled its VelociRaptor 600 this past March as a considerable update to the stock 2017 Ford F-150 Raptor, but how much quicker is it? HPE will answer that question directly. The performance house set up a simple quarter-mile drag race to see how its modifications...

An off-road racer's pre-runner truck is a tool for making sure that the course to be tackled is first thoroughly investigated. You want your co-driver to know where the bumps, ruts, and other pitfalls are. This way when you're blasting across the desert at 100 mph in the dark of night, you have an...

Did you buy a Dodge Challenger SRT Hellcat? Good for you! That means you have an entertaining 707-horsepower mean machine parked in your driveway. A question though, if we may. Do you ever wish you had more horsepower on tap?As you might expect, Hennessey Performance has a power package for you...

Saleen hasn’t always been a manufacturer and tuner of high-performance cars. Back in 1986, just three years after the company was founded, Saleen entered the SCCA/Escort Endurance Championship with a version of its Saleen Mustang prepped for motorsport duty. One year later, Saleen took home...

All-wheel drive is not conducive for a traditional burnout, but Hoonigan got creative to make it happen. Taylor Steffes, the owner of the Nissan GT-R in this video, drove her car from Arizona to California to just to say hello to the guys and gals at Hoonigan. But, really, she's also a participant...

The world of high-horsepower builds is an insane place. While production cars with 500, 600, and even 700 horsepower are considered wild, it's the aftermarket that takes things to the next level. And then past that level and into the stratosphere. Case in point is the Nissan GT-R from Extreme Turbo...

For two years back in the mid 1960s, Honda produced a fun little sports car that wore the name S600. You could get it as a coupe or a roadster, and power was provided by a 606-cc flat 4-cylinder engine. It produced a mighty 57 horsepower, and nobody at the time thought of it as a drag car. The...

There is a 1965 Ford F100 in my garage. I've owned it for a few years, performed a few mechanical fixes and upgrades over the years, and I love my truck. It's a good "ten footer" and a pleasure to take on cruises. Jonathan Ward of Icon doesn't build "ten footers." He builds amazing machines to his...

Underground Racing is back at it, and it seems nothing can slow the shop down. Less than seven months after the performance house set the half-mile world record of 247 mph in a Lamborghini Huracán it built, it's back, this time with Gidi Chamdi behind the wheel of its latest Huracán...

If there's one country other than the United States that has a bonkers relationship with power and oddball builds, it's Australia. Take this Nissan GT-R-powered Ford Focus for example. Okay, so it's not exactly a Ford Focus anymore—it only shares the windshield and A-pillars at this...

Staging a car at a drag strip is an art form. You line up so you have your car exactly where you want it to try and extract tenths of a second as you blast off down the strip. Some like staging deep while others run shallow. However, for some, staging is now moving beyond the art form and into the...

HGK Motorsport is a Latvian race shop that is churning out some seriously powerful machines, and its focus is on a handful of BMW platforms. The crew over there has a soft spot for the E36, E46, and E92 M3s. Now, though, HGK has a new jumble of Bavaria's finest alphanumerics in its stable: the F22...

Remember Tesla's Roadster? That was a pretty neat little machine that paved the way for grander offerings from the electric car company. It was built on the bones of the Lotus Elise. The final version saw 288 horsepower and nearly 300 pound-feet of torque from its electric powertrain. Today...

Drag strip loss got you down? There's a quick remedy for that: nitrous oxide. But how much? How does a shot of nitrous worth about 5,000 horsepower sound? That's sure to do the trick. This isn't anything like Brian O'Conner's request ("I need NOS, one of the big ones"); this is a kick in the pants...

The humble Peugeot 106 makes a paltry 118 horsepower in its most vicious trim. This one makes 500, all thrashing through what began life as a stock 1.6-liter inline-4. Built to take on time attack events, the car has abandoned all of its former life as a commuter. There's a massive turbo sticking...

There's nothing wrong with a 1977 AMC Pacer that a 351 Windsor can't fix. These things came from their Kenosha, Wisconsin manufacturing facility with one of two inline-6s: a 238 or a 258. The latter, more potent mill produced an unflattering 114 horsepower and 192 pound-feet of torque. At around...
