Chrysler almost smothered the Hellcat before it lived

Chrysler's 6.2-liter supercharged Hellcat V8 was an absolute sensation from the very moment it was announced, and honestly, how could it not have been? Packing 707 horsepower and 650 pound-feet of torque, its numbers immediately put every other production muscle car (and many supercars) to shame. Plus, we soon learned that would be wrapped in a package retailing for around $60,000 - a pittance compared to other vehicles offering similar grunt. However, the Hellcat almost never got the chance to rumble under the hood of the Challenger and Charger.
The Hellcat was initially proposed back in 2011, back when Fiat was deciding its future strategy for Chrysler Group, according to Automotive News. At the time, the company was just emerging from its bankruptcy doldrums, and an ultra-high-performance V8 wasn't exactly a must-have item. The program didn't move forward. However, SRT engineers kept fighting, according to AN, and four months later, they received the green light to pull the project off the shelf and continue developing the Hellcat. The muscle car world is certainly better for that decision.
The work of those engineers focused on taking Chrysler's standard 6.2-liter V8 and making it reliably handle all of the extra power from the supercharger. "It came down to micron levels of changes in the crank to be able to withstand the pressures of the engine," said Chris Cowland, director of advanced and SRT powertrain, to Automotive News. The changes amounted to switching out about 91 percent of the parts to make the Hellcat, including some quite minuscule alterations. For example, the washer holding the supercharger pulley is embedded with industrial diamonds to keep it from slipping.

A look at the Dodge Demon's drag settings, modes, and go-fast tech

In the same video that gave us a peek at the 2018 Dodge Challenger SRT Demon's performance stats, there's a serious dump of info on the tech and tools that will likely help this muscle coupe slaughter drag strips. Dodge has outlined a few of them for us and we're using the power of inference to figure out the rest. Here's what we've gathered. A lot of these hints come from the Demon's version of Performance Pages, the infotainment screens that show what SRT models are doing and let the driver change the powertrain and chassis setup. There are a lot of Demon-only features, including line lock, a quick cooldown mode for the supercharged engine, and data recording. And of course there are pages to show a digital time slip with acceleration and braking figures, a g-load plot, and lots of gauges to track temps and levels. The engine output is shown in the video on a special Dyno page. It tracks horsepower and torque over time on the upper graph, and engine rpm and shift points on the lower graph. And we think it's still hiding something. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Any good drag car has a line lock, allowing the driver to lock the front brakes and leave the rears free to do a nice tire-warming (or tire-shredding, depending on length) burnout. Ford has it on the Mustang, Chevy puts it on the ZL1, and now Dodge is adding it to the Demon. It should help get the giant Nitto tires up to temp for a drag run. And once the tires are warm, there's launch control, just like on the SRT Hellcat, with selectable rpm to dial things in for the conditions. The Demon also has a shift light in the cluster, and the driver can set a shift point individually for each gear. After each drag run, you can activate Quick Cooldown, which Dodge says uses the first production application of After-Run Chiller – it runs the cooling fan and intercooler coolant pump with the engine off until the coolant reaches its target temp. It's shown in one of the slides above. The checklist on the left side of that page suggests it requires a set of conditions be met to work: engine off, hood open, and sufficient battery level. This further reinforces our theory that the supercharger is going to make big boost, beyond the Hellcat's 11.6 psi. And while you're waiting for the supercharger to cool off for another run, you can review the performance data the car records.

Mopar Hellephant crate engine sells out in 48 hours

This happened so quickly that we're only just catching up with it. Mopar opened pre-orders on the 7.0-liter Hellephant Hemi crate engine on April 26, which is Hemi Day. According to Allpar, hubbub on social media not long after that day claimed Mopar had gone through all of its Hellephant stock. When Allpar asked Fiat Chrysler for clarification, a spokesperson e-mailed, "Given the high demand and the hand-built, time-intensive build process, we have closed preordering for the 426 Hellephant Supercharged HEMI crate engine. Based on preorders, the engine sold out in just two days. Customers can visit www.cratehemi.com to receive future information and updates on the 'Hellephant' engine." No one is certain how many engines Mopar sold. Allpar wrote, "Industry insiders believe Mopar may be making around 100," but reiterated that it's a guess. The engine and the ordering process have their peculiarities. Mopar Insiders explained that Tool Engineering International helped create the 426-cubic-inch block, and that the Hellephant engine "shares nothing except for displacement with the rumored upcoming 7.0-liter 426 Hemi V8." On the Hellcat.org forum, a poster wrote that the engines "can only be sold through a dealer and that the dealers can only order 1 engine per week." The Hellephant doesn't come with Mopar's three-year, 100,000-mile warranty, either. During a press briefing last October, FCA officials said they weren't sure about offering any warranty. Based on the motor being given a part number starting with the letter P, there is a bit of protection, but it's a 90-day limited warranty covering "defects in materials or wokmanship," and only applies to engines not used in competition. For those who didn't get the opportunity to drop $29,995 for 1,000 horsepower and 950 pound-feet of torque, the best bet is to hope for the return of Apollyon's pachyderm. Motor1 wrote that "Rumors hint at... another limited run scheduled for next year due to overwhelming demand." That's thin thread to hang a Hellephant from, but it beats bupkis.
