Dodge Challenger Super Car on 2040-cars

Cold start comparison: 2020 Alfa Romeo Giulia Quadrifoglio vs. 2013 Dodge Challenger SRT8

The 2020 Alfa Romeo Giulia Quadrifoglio is a five-seat, compact luxury sport sedan packing 505 horsepower thanks to a 2.9-liter twin-turbocharged V6. My personal 2013 Dodge Challenger SRT8 392 is ... well ... not. It's a full-sized muscle coupe whose iron-block 6.4-liter V8 makes 470 hp in the very traditional way: it's freakin' huge, like everything else about the car.  On paper, these two have nothing in common beyond the fact that they were built by the same multi-national manufacturing entity.  But if paper were the be-all and end-all of automotive rankings, everybody would buy the same car. And we don't, especially as enthusiasts. Whether it's looks or tuning or vague "intangibles" or something as simple as the way a car sounds, we often put a priority on the things that trigger our emotions rather than setting out to simply buy whatever the "best" car is at that particular moment.  So, what do these two have in common? They both sound really, really good. Like looks, sounds are subjective. While a rubric most assuredly exists in the world of marketing (attraction is as much a science as any other human response), we have no way of objectively scoring the beauty of either of these cars, and the same applies to the qualities of the sound waves being emitted through their tail pipes.  But we can measure how loud they are. In fact, there's even an app for that. Dozens, as it turns out. So, I picked one at random that recorded peak loudness levels, and set off to conduct an entirely pointless and only vaguely scientific experiment with the two cars that happened to be in my garage at the same time.  For the test, I opened up a window and cracked the garage door (so as not to inflict carbon monoxide poisoning upon myself in the name of discovery), and then placed my phone on a tripod behind the center of each car's trunk lid. I fired each one up and let the app do the rest. I then placed my GoPro on top of the trunk for each test so that I could review the video afterward for any anomalies.  I started with the Challenger. The 6.4-liter Hemi under the hood of this big coupe is essentially the same lump found under the hood of quite a few Ram pickups, and it has the accessories to prove it. Its starter is loud and distinctive. Almost as loud, it turns out, as the exhaust itself. As its loud pew-pew faded behind the V8's barking cold start, we recorded a peak of 83.7 decibels. In the app's judgment, that's roughly the equivalent of a busy street.

SpeedKore carbon-fiber 1970 Dodge Charger packs a 996-hp Demon engine

SpeedKore Performance does some pretty neat things with carbon fiber. SEMA is always the place to show off new and interesting builds, and SpeedKore has a few new offerings on display. We talked about the lightweight carbon fiber 2018 Dodge Demon late last week, but now that SEMA 2018 is in full swing, we've got a look at something even cooler, an all-carbon, Demon-powered 1970 Dodge Charger "Evolution." SpeedKore Performance is based in Wisconsin and has been churning out SEMA showstoppers for years. In addition to the Demon, take a look at this Shelby GT350R the shop modified a few years back. The Charger Evolution is named so because it further modifies the SpeedKore Charger "Tantrum" that was used in the " Fast and Furious" films. That car used a carbon composite body and was fitted with a 9.0-liter Mercury Racing twin-turbo engine making an absurd 1,650 horsepower. The Evolution might be down on power — only 996 horses thanks to a modified Demon crate engine — but the goal was to create something a little more usable than the Tantrum. Upgrades include a smaller supercharger pulley, larger fuel injectors, a custom cold-air intake, stainless steel headers and a custom exhaust with SLP mufflers. There's also a Dailey Engineering dry sump, upgraded oil cooler, and Saldana radiator. It's also lighter, thanks to even more carbon fiber. SpeedKore had a goal to get the '70 Charger to about 3,200 pounds. To get there, the Evolution employs carbon-fiber bodywork, an aluminum floor, a steel roll cage and a new 2x3-inch steel box frame. SpeedKore's autoclave is large enough to bake a one-piece roof, hood and quarter panels. The bare bodywork has been finished with a clear coat to help prevent fading. The Evolution uses billet aluminum for the door handles, fuel cap and grille, all finished in a bronze-nickel coating to pair with the HRE wheels. In addition to the floor, aluminum was used for the firewall, transmission tunnel and radiator shroud. To slow the Charger down, it uses Brembo brakes with six-piston calipers up front and four-piston calipers in the rear. The suspension uses Penske adjustable coilovers while Michelin Pilot Sport 2 tires wrap 19x10-inch front wheels and 20x12-inch rear wheels. Related Video: This content is hosted by a third party.

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.
