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

challenger 392 dyno 450x300 2011 Dodge Challenger SRT8 dynod   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.

Oshkosh Light Concept Vehicle competes in Baja 1000

Yep, that’s a diesel hybrid Light Concept Vehicle (LCV) from the Oshkosh Extreme Racing team competing in the 43rd running of the Tecate SCORE Baja 1000. “Light” in this case is relative, of course. Oshkosh builds a large variety of bigger machines, ranging from fire trucks to rigs capable of hauling up to 70 tons.

Now, the Oshkosh outfit didn’t win the event. In fact, only one of its two entries finished, and it was six and a half hours too late to be scored. It was, though, an opportunity to see how Oshkosh’s ProPulse hybrid system would hold up to the rigors of off-road abuse. In that department the race was a success.

According to the Oshkosh, the hybrid system uses a diesel engine to send power to a generator which, in turn, directly powers the wheels (Though not stated, we imagine there’s an electric motor involved for each set of wheels.) In place of batteries, the setup relies on ultracapacitors to store and deliver energy. The arrangement is said to reduce fuel consumption by 20 percent thanks to the elimination of components such as the torque converter, automatic transmission, transfer case and driveshafts. To get a better look at this beast, check out the gallery below or the video of it in action after the break.
