2011 Dodge Challenger SRT8 dyno’d – is the 392 underrated?

Hemi. The mere mention of the word is enough to strike fear into the hearts of lesser powerplants… or at least images of a pair of scrubby-looking bottom-feeders that really love themselves some Ram Trucks. In any case, we’re keenly interested in the latest Hemi engine from the Dodge Boys, in this case displacing a heady 392 (or so) cubic inches and placed gently inside the engine bay of the 2011 Challenger SRT8.

Not only is this new Hemi larger than the already oversized version it replaces, it’s also considerably more potent. The Pentastar says that its new 392 kicks out 470 horsepower and 470 pound-feet of torque – substantial improvements over the outgoing SRT8’s 425 hp/420 lb-ft. But those are factory ratings, and we all know those don’t necessarily match what’s actually under the hood of production models.

Thankfully, the crew over at Inside Line managed to score enough time with a 2011 Challenger SRT8 to strap it down to a proper dyno. And the results? How about 452 horses at 6200 RPM and 443 lb-ft at 4400? Yep, that’ll do nicely, and it means that Dodge may actually be underrating its potent performer just a tad. Oh, and for what it’s worth, IL managed to record 370 horses and 343 lb-ft from its 2010 Chevrolet Camaro SS on the same exact dyno. Chevy’s answer ought to be coming in the form of a Z28 with over 500 supercharged ponies… Stay tuned, the horsepower wars are clearly still in full swing.

2011 Dodge Challenger SRT8 392 is the crème de la Chrysler

Chrysler made waves earlier today when it announced the company would have an armada of 35 vehicles on display at this year’s SEMA show, but the star of the shindig is likely to be the new 2011 Dodge Challenger SRT8 392.

While no one has ever accused the Challenger SRT8 of being light on grunt, Chrysler engineers have taken things up a notch or two with a new 6.4-liter V8 that produces 470 horsepower and 470 lb-ft of torque, all while delivering 15-20 percent better fuel economy than the outgoing 6.1-liter V8 in the 2010 Challenger SRT8. The big V8 uses variable valve timing and cylinder deactivation to help keep consumption low.

The Challenger SRT8 392 also employs a reworked suspension with even firmer shocks, a quicker steering ratio and more negative camber than before, all of which are supposed to help the hefty muscle bruiser tackle the corners with a little more finesse.

Up front, there’s a unique chin spoiler that helps channel air to the vehicle’s radiator and provide additional downforce at higher speeds. It also just looks pretty dang sharp.

Chrysler says it will build just 1,492 inaugural editions of the Challenger SRT8 392, and that the cars will be available to buy right after Thanksgiving. Hit the jump for the full model-specific press release.

Reader Spy: Are you the next Dodge Charger SRT8?

It’s no secret that Chrysler is unleashing redesigned versions of the 300 and Dodge Charger sedans this Fall and we’ve seen numerous images of them prowling the streets of suburban Detroit in recent months. Now another of Autoblog’s eagle-eyed readers, Marty M., has dropped us a note to let us know that he had captured what appears to be the new SRT8 version of the Charger.

We’re assuming this is the high-output Charger based on the size of the wheels and rear deck appendage, along with the depth of the front air dam. The freshly contoured flanks are visible under the camo, but we can’t quite tell if there is a new piece of glass at the trailing edge of the rear doors. The new SRT8 engine is expected to grow from the current 6.1-liters to 6.4-liters with at least 450 horsepower, and shooter Marty tells us it sounds very much how a big V8 ought to. It isn’t known if the high-performance SRT version of the next Charger will debut alongside its lesser linemates for model year 2011, or if it will hang out until it can earn a 2012 designation. Either way, it’s time to get excited.

Spy Shots: 2012 Jeep Grand Cherokee SRT8 spied with 6.4L Hemi V8 underhood

Filed under: Spy Photos, Performance, SUV, Jeep

The 2011 Jeep Grand Cherokee – the pride and joy of Chrysler at the moment – is just now hitting dealerships, but the automaker is already hard at work on a high-powered SRT-fettled version of its new sport ‘ute. In the past, the Grand Cherokee SRT8 has always been a guilty pleasure of ours, if only for the rocket-like 6.1-liter Hemi V8 underhood.

Good news then that Chrysler is prepping an all new 6.4-liter Hemi for use in its SRT products, and we’re anxious to see how this new engine works in the Grand Cherokee application, which seems likely to hit as a 2012 model.

Early reports suggested that it could be good for around 450 horsepower, but spy photographers are saying that we could see over 500 raging stallions coming out of this new monster mill. This means the new Grand Cherokee SRT8 could rip off 0-60 times in under five seconds, and we might have a truly worthy American competitor for the Porsche Cayenne Turbo, AMG-badged Mercedes-Benz ML and BMW X5 M. Here’s hoping.
