Before Jay Leno, this 1970 Dodge Charger was a SEMA star

When Jay Leno drives an awesome car, enthusiasts take note, and this week the internet blew up over the 1970 Dodge Charger resto-mod that starred in a recent Garage episode. But you might not remember: this strapping Charger, called "Tantrum," was one of the highlights of the SEMA Show in Las Vegas last fall. Here's another look at a true Mopar monster. The power: Yep, Tantrum has 1,650 horsepower. That's more than two Hellcats worth of power under the hood. It's a twin-turbo 9.0-liter Mercury Racing engine with a quad-cam four-valve setup. Basically, it's a V8 boat motor developed for cars. Mercury Marine is the crew that developed the V8 for the 1990s Chevy Corvette ZR-1. That all-aluminum LT-5 under the hood cranked out 405 hp – an astronomical figure for the time – and helped make the ZR-1 an icon. Take a listen to Tantrum's 9.0-liter Mercury mill below.

You might not know: Tantrum won the Best Domestic category of the GT Awards at SEMA – chosen by your author. The sinister looks were the hook, and the crazy engine solidified its performance cred.

2018 Dodge Durango SRT First Drive | Speed, and space for six

We're gathered along with other members of the media at the Indianapolis Motor Speedway to drive a trio of new vehicles from Dodge's performance arm. Alongside a pair of SRT Challengers – the Demon and the Hellcat Widebody – the 2018 Dodge Durango SRT towers over the coupes, and is surprisingly menacing to behold. Its proportions may be relatively simple, but its hood scoop, air vents, and aero features let us know that this car is built for performance. A set of sporty wheels and bright Brembo brakes reiterate its purpose. A badge on the fender bearing the number "392," denoting the V8's displacement in cubic inches, gets us thinking about classic muscle. Even with the Demon sitting feet away, just looking at the Durango has us excited to drive it. Our first stint in the Durango SRT takes place on the infield road course at Indy. We had just gotten out of the Challenger SRT Hellcat Widebody, driving the same circuit, and we expected the Durango to seem tame by comparison. We were mistaken, mostly. The Durango SRT's seating position feels very upright, particularly due to a helmet that kept us from settling into the headrest. Still, we make ourselves comfortable, able to adjust the steering wheel right where we want it. Everything is in Track Mode – transmission, AWD, suspension, and steering – except for stability control, which is still set to Street. Taking off from behind Indy's famous bricks, throttle tip-in is quick, and the Durango SRT springs to life. The Durango feels fast under wide-open throttle in a straight line, which is impressive consider we had just gotten out of a louder, faster coupe. Dodge claims a 0-60 time of just 4.4 seconds, and it's that kind of acceleration that makes us agree with Dodge's boastful claim that the Durango SRT is a "three-row Charger." Then we take the first corner. The steering feels progressive, if not super tight, but the size and weight of the Durango quickly make themselves known. Body roll reminds us that this is, in fact, a tall utility vehicle, and definitely not a Charger. We lean to the side as the tires dig in, pulling the Durango around its axis and toward the apex of the corner despite the lateral momentum they are fighting. We're hesitant, but the instructor in the passenger seat coaches us to keep on the throttle despite what our inner ear is telling us. The Durango manages to stay stuck to our line as we push harder through the corners than we had thought possible.

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!"
