Hellcat motor 'fits like a glove' in the Wrangler and Gladiator, says Jeep

Just like "technically correct" is the best kind of correct, "technically possible" is the best kind of possible. Specifically, it's technically possible to slot a Hellcat crate motor into the Jeep Wrangler and Gladiator, as confirmed by Jeep brand chief Tim Kuniskis. Speaking to Australian media last week, Kuniskis went on to say that "everybody" keeps asking him if the supercharged, 6.2-liter Hellcat V8 fits in the Wrangler and Gladiator, and that the answer is yes. "It fits like a glove," said Kuniskis. But — there is a but — the fitment is so close for comfort, it makes the combination one that Jeep can never produce. "There's no air space around the engine [...] so you have no crush space, you have nothing that can be used to absorb energy in a crash. It's not a problem to put it in — other than emissions and fuel economy — except it would never pass any crash tests, and that's a problem," as Kuniskis told Drive. However, since the Hellcat is now out of the bag, it's probably only a matter of time until hobbyists with access to these engines will start putting them into Wranglers and Gladiators. And with the time-honored piece of advice — just don't crash into anything — it'd be a combination worth seeing and hearing. Just to throw it out there, a "Hellcrate" engine costs less than $20,000 new. Kuniskis also said that Jeep is "gauging interest" for the J6 concept, one of the Easter Jeep Safari concepts that were just revealed. "[The J6] is just a concept at this stage. But that doesn't mean we're not going to gauge interest for it." However, he said justifying its production is apparently "tough."

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!"

Hellephant 1,000-horsepower Mopar crate engine priced, is available to order

The folks at Fiat Chrysler's Mopar division unveiled its meanest road-going V8 ever at last year's SEMA show. It makes 1,000 horsepower, and it's called the Hellephant in honor of the second-generation Charger's 426 "Elephant" V8, and because it has a honking big supercharger on top like the modern Hellcat. What we didn't know was the price, but now order books are open, and it's priced at $29,995. That's about $10,000 more than the currently available Hellcat engine, which makes 707 horsepower. You'll also probably want to buy the available kit that comes with all the computers, wiring, sensors and throttle to run it, and that's an extra $2,265. Putting things further into perspective, you can actually buy an entire new Dodge Challenger SXT V6 for $29,340. You'll also still need to add other accessories if you want things like air conditioning, which Mopar is also happy to sell you. What we're saying is, this is a lot of money just for an engine. But on the other hand, this is a roughly plug-and-play engine with Bugatti Veyron power for the price of a V6 Challenger, so that's pretty awesome. And you can put it into anything you have the skills or money to put it in. Plus, it should be able to make more power with higher-octane fuel. We can't wait to see the swaps and builds.
