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.

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.

Before it threw a Tantrum, it did the "Cudinator" used in some of the Fast and the Furious movies. 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.

2016 Dodge Viper ACR First Drive [w/video]

The Dodge Viper is not a comfortable car. Livable, yes. The interior is covered in fine materials. But you still climb over a hot door sill to enter the tiny cabin. And the frequency range of the engine's noises seem specifically designed to cause headaches. What happens, then, if you remove all pretense of civility from a Viper and add equipment solely aimed at improving lap times? You would have the 2016 Dodge Viper ACR. In terms of achieving its purpose, this car is a absolute success. In many ways it's also the most honest Viper of the current generation. Prices start at $121,990 (including $2,100 gas-guzzler tax and $1,995 destination), or $32,900 more than the least expensive Viper. In ACR trim, the Viper loses the under-carpet padding, 9 of 12 speakers plus amplifier, carpet and trim from the cargo area, and sound deadening in front of the rear wheel wells. The parts of the interior still covered add healthy amounts of Alcantara or optional carbon fiber. That weight loss is compensated by the addition of go-fast bits like the giant rear wing (or the larger "x-wing" on the Extreme Aero Package), 10-way adjustable Bilstein Motorsports shocks, Brembo carbon-ceramic brakes, a rear diffuser, and a front splitter. Total claimed curb weight is 3,392 pounds in Aero trim (standard ACR trim is 18 pounds lighter), which is within a few stone of the rest of the Viper lineup. The diffuser strakes and leading edge of the splitter are removable, made to be replaced after rubbing on track tarmac and make street driving slightly more practical. Not that you'd want to drive the ACR on the street, with the lack of noise insulation and spring rates twice as stiff as the Viper TA, but it is street-legal. Dodge claims the DOT-approved Kumho Ecsta V720 tires on the ACR allow faster lap times than some race compound tires. Our test was limited to on-track shenanigans at Virginia International Raceway. Which is fitting because we wouldn't have anything good to say about driving the car on the street. The ACR is, essentially, a race car sold in the showroom, although with the Viper's 1 of 1 customization program, your custom build can include as many creature comforts as you like. Lined up in pit lane at VIR, the Viper ACRs for our evaluation blur the air with heat shimmer. All of the test cars have air conditioning, but that shuts off at full throttle with a six-second reset.
