Chrysler readying Hellcat V8 with Viper-like power

A monstrous supercharged V8 engine could be in store for Chrysler and SRT products, if recent rumors are to be believed. Allpar is reporting that the forced-induction V8 - Chrysler's first, if this goes down - could make its debut this summer.
The story goes that the Hellcat would be based on a 6.2-liter Hemi engine, rather than on the existing 5.7- or 6.4-liter versions of the company's vaunted mill. In any case, the general consensus is that the motor will have gobs of power. Modest estimates call for between 500 to 570 horsepower, with some outliers predicting a figure as high as 600 hp. That figure would put the output would place the Hellcat awfully close to that of the 640-hp V10 in the SRT Viper, too. Allpar contends that a slightly lower powered version would allow Chrysler to keep costs below that of the more powerful Ford Shelby GT500, which might be a sweet spot.
The Hellcat could debut in a number of SRT products. SRT versions of the Charger, Challenger and 300 are all up for grabs, as is the rumored SRT Barracuda.

Here are the Challenger SRT Demon's bare-minimum performance numbers

This week's Dodge Challenger SRT Demon teaser video provides what seems like more concrete evidence than any of the others before it. We say it seems that way because the numbers flashed on the screen are likely not showing us everything the car has to offer. So we're looking at these as the minimum performance stats and expecting Dodge to reveal even crazier numbers alongside the car next month. The video also provides some hints at features and modes the car will offer. Let's pick it apart. First off, there's the performance data from the various SRT Performance Pages screens. The 0–60 mph time is 3.0 seconds, which compares well to the "regular" Hellcat's 3.5-second manufacturer claim. Then there are two 0–100 times: 6.08 and 6.8. An eighth-mile time of 6.6 seconds at 125 mph and a quarter-mile time of 0.5 seconds at 129 mph lead us to believe the driver lifted off the throttle in that second eighth-mile and that the car will actually do the quarter in the low 10s. For reference, Dodge claims an 11.2-second quarter for the Hellcat on its street tires and a 10.8 with race slicks.

A graph shows it heading up toward 10 psi but the final spike is obscured by a Demon head. Cute. There's a hint at horsepower and torque numbers in a graph on the Dyno page, which shows both peaking around 750. In every shot of this video, the clock is set to 7:57, which we think means it either has that much power or, well, more. We think there's more to it because it appears that part of the graph above the dyno run shown, which would reach to 800 or 850, has been blanked out. A horsepower total of 808 would be a nice complement to the Hellcat's 707, don't you think? We can see from the shift indicator screen that the car will come with or at least offer the eight-speed automatic that's also available in the Hellcat and other Challengers. That's likely to be the best option for drag racing. The Demon's user-defined shift light feature, which lets you choose an optimal shift rpm for each individual gear, also suggests that a six-speed manual will be available. We'll cover the many modes and settings highlighted in this video in a separate post. There's a lot to discuss. Related Video: This content is hosted by a third party.

Somebody created a Dodge Challenger SRT Demon droptop

The Dodge Challenger SRT Demon is a vehicle built with one purpose in mind: going fast down a drag strip. Weight is the enemy when it comes to acceleration, and one surefire way to add weight to a car is to make it into a convertible. However, that’s exactly what one Demon owner decided to do to their Challenger. Motor Authority spotted this Plum Crazy Demon convertible conversion for sale online, and the dealer and builder even spilled a few details on the car itself. This particular conversion was done by Droptop Customs, a shop with experience, having previously converted a couple Challengers into convertibles for Shaq in Miami. However, ripping the roof off the 840-horsepower Demon is no small task. ThatÂ’s a ridiculous amount of horsepower to handle for a car that has lost a fair amount of structural rigidity from removing the roof. The Droptop Customs sales manager told MA about the changes that were made to make this build work. To begin, the frame rails were reinforced with 1x2-inch pieces of metal. Then, the shop added diagonally-mounted metal braces underneath to resist twist. Even more structural supports were added to the trunk, front and rear shock towers, and gussets were added to the bottom of each door to keep them from moving. Lastly, the shop boxed the connection of the front rails to the engine cradle. No specifics about weight gain were provided. There is one sad bit of news about this Demon, though. The dealer told MA that itÂ’s currently on consignment, despite being listed for sale on FCA dealership Cape CoralÂ’s website. ItÂ’s priced at an eye-watering $145,995. But the new owner wonÂ’t have to manually put down the top! ThatÂ’s right, itÂ’s powered, and itÂ’s supposed to take about 20 seconds to lower or raise into place while stationary. Somehow, the car has only 172 miles on it, so itÂ’s hardly been used. We have no photos with the top up, so youÂ’ll have to settle for top-down photos for now. It looks like a professional job through and through, and we actually dig the convertible look. Plus, who doesnÂ’t love Plum Crazy?
