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.

      What was the power to weight ratio of the older cars compared to now?
      • 4 Years Ago
      Maybe someday we'll get to see a 426 or 440!!! With that said, I love this car.
      • 4 Years Ago
      At least you've got roads big enough to unleash 452 BHP, ours are littered with Gatso speed cameras or little yellow tax boxes. The Camaro looks smart in white with the blue stripes, its one of those cars,along with Mustang, that take a varirty of colours well.

      Chrysler has Always understated their HP Numbers

      Man , what a beautiful muscle car . All that room in front & back with a huge trunk to boot . Plenty of headroom ,shoulder & hip room . Real comfort on long extended cruises . The best sounding engine & exhaust system stock from the factory . I'll take mine in blue , just like the one pictured with a nice big moon roof & camel interior . Send me the bill !

      where have you guys ALL been? in Cali one of the 392 mules was dynoed at 449rwhp on piss 91 octane yet still managed to pull off 12.4s @ 110-111

      Every MoPar fan knows that Chevy could NEVER match Dodge at the drags. Yea, Chevy makes a great race car, but only the HEMI is put in a class by itself (SS/AH)because nothing, and I mean NOTHING, can stay with a HEMI MoPar.
      Chevy straps on a supercharger on its Z28, Dodge straps on a supercharger on its HEMI--game over--again !

      You're only going to see better and better ET's from those cars. The stock air box on the LX cars is very restrictive, and the mid pipes on the exhaust are too. Many 6.1L cars got major gains just by swapping those out and the gains will be even more substantial on the 392's I am sure.

      Plus, the 12.40 pass was one driver in a car with probably 20 un-broken-in miles on it. I wouldnt be surprised to see 11.90's from a few of them in the very near future.

      Dynojets consistently run higher numbers than Mustang dynos. I work a Mustang dyno at the tuning shop where I work and I hear massive numbers from Dynojets all the time. Impressive numbers nonetheless, can't wait to tune one of these from the DFW LX Club!

      You know what, I know that dynamically it's the worst pony car, & the interior isn't the best either (better than Camaro though), but I'll be damned it if doesn't look good... better than Mustang or Camaro to these eyes.
        • 4 Years Ago
        I would agree that this is the cleanest retro-muscle.

        Not that it looks exactly like the Challenger it reminds people of... it is much thicker looking...

        But the lines are clean. No bulbous fender flares, no cartoonish proportions, or overly swollen bumper protrusions. The details are well crafted. The Camaro looks like a cartoon from every angle, and the Mustang doesn't look very good from the back, and the front is pretty blunt, with wide bevels on the edges, as well.

        But it is still a huge beast of a coupe, and very heavy.

        Pure thumbs up on that fantastic shade of blue on the pictured 392.

        ITS NOT A "PONY" CAR!!! Its a MUSCLE car. The only one sold in America. "Pony" cars don't have 116 inch wheel bases. They have 108 inch wheel bases. It was never meant to compete with the Mustang and the Camaro. That was never mentioned. Its the coupe version of the 4 door Charger.
        • 4 Years Ago
        +1, that is exactly what my opinion is regarding the pony cars.
        • 4 Years Ago
        Same here.
        My dream mix of the three would be a Mustang chassis with a Challenger body and a Camaro (Z28 plz) engine under the hood. :D
      • 4 Years Ago
      452rwhp is awesome but can you imagine how much better this thing would be if it lost some weight.
        • 4 Years Ago
        or gained some traction from an improved weight distribution.
      • 4 Years Ago
      The car already ran a 12.4 @110.7mph at Infineon's drag strip. I"m pretty sure that Dodge is "sand bagging" just a little.
        • 4 Years Ago
        I've got to agree with you there, this thing is as big as a barn, they're not getting those ETs with the claimed engine ratings that they published.
