2011 Dodge Charger R/T and Challenger SRT8 392 – Click above to watch the video after the break

As part of its Hemi Highway Tour, a country-wide tour that started in November of 2010 and just recently came to its end, Dodge decided to stop and spend some quality time with the boys and girls from National Speed in Wilmington, NC. Though that company's main purpose is modifying high-performance machinery to make even more power, Dodge decided to put a couple of its brand new 2011 models on their dyno to see what kind of power could be had right off the showroom floor.

As a preface to the actual dyno results, you should know that Ralph Gilles, Dodge Car Brand President and CEO, claims that a bone-stock 2011 Challenger SRT8 392 ran the quarter-mile at Infineon Dragway in just 12.44 seconds at 110 miles per hour. That, boys and girls, is seriously fast. And those figures are backed up by the data spat out by the computers hooked to National Speed's dyno.

Without further ado, the numbers: The 2011 Dodge Charger R/T put down 327 horsepower at the rear wheels and 349 pound-feet of torque. For a car rated at 368 horses and 395 lb-ft, that's quite good. Remember, the dyno measures power after it's already gone through the transmission and through the wheels to the ground, which saps around 15 percent of total power.

And now on to the big guns. The 2011 Challenger SRT8 392 was measured at 420 rear-wheel horsepower and 419 lb-ft of torque. Also impressive when stacked up against its factory ratings of 470 ponies and pound-feet. Even more interesting, these same machines put down ever more power just a few days later on a different dyno, though still below the 452 horses obtained by the scribes at Inside Line. Enough talking already. Check out the video after the break. Thanks for the tip, Norm!

      Wish I knew why so many people keep trashing these MOPARs. I drive a Cobra but still really like these cars. I keep hearing people whine about the Challenger interior but, after checking out a new SRT8 version, I think the interior is just fine. IMO, any car that can hit a 12 second 1/4 miles is MORE than fast enough for the street. Beyond that, I think people are simply bench-racing. I say kudos to Dodge!

      This 15% drivetrain loss "fact" gets thrown around way too much. Do you really think this car is losing 70hp to drivetrain losses?? That is enough power to run over 860 60 watt light bulbs. Now think of how much heat that would put out and imagine all that heat concentrated in the transmission and rear end. It's not happening. Parasitic losses aren't constant at 15%. It might be that for a 120hp car but that number will drop as power goes up. There is no way these cars are over rated and making 490hp at the crank. I bet in reality they are making less than the advertised 470hp.

      Now all they need to do is to give the Challenger an interior facelift. The Challenger interior looks boring compared to the Camaro's and Mustang's interiors. Perhaps something from the Challenger concept's interior would be okay.

      Well national speeds dyno tends to read on the very high side and the people there suck but I love the cars just around here in Jacksonville they are known to blow up cars

      The numbers are impressive, but the video itself is totally lame. They didn't even put in any engine noise while on the dyno. Boring.

      @ Kenneth L ,

      With this much power the car will spin off the line,so yeah a Dodge guy knows how to drive it better so 12.44's are right on the mark..look at the mph !! The Mustang could run high 11's if it had slicks...bet the Challenger would as well..

      It's like the old Mopar cars of yesterday,they spun like crazy and reported 14 and 13 second 1/4 miles from a stock,new 440 4bbl !!! If you ever drove one, and one that is 100% stock will run the 1/4 mile in the low 12 second range (with bigger tires)and with stock tires they ran high 13's-14's....Car Life did a test changing over the rear tires to a bigger 8 inch wide tire,but needed more traction still..and it ran low 12's,street tires 14 flat ! Those days are back...

      What the fook does "twoest" mean?

      The greenies would love to outlaw these cars.

      This just in Challenger faster on straights, still slow in corners.

      Since not one auto magazine got close to the 12.4 time I really doubt dodges numbers with all of the magazine times in the 12.9 to 13.0 second times. The 2011 GT500 with a better power to weight did a 12.4 at 117mph in car and driver and with a best of 12.2 at 119mph in Autoweek. The best time for the SRT 392 is 12.9 at 114mph by car and driver. So I would think Dodge is doctoring the numbers since no one else has duplicated those numbers in the real world. Dyno 1/4 mile times are meaningless in the real world.

        @Kenneth L:
        The 'car and driver'-test with 12.9@114 was done using a manual transmission 392.
        I bet there is quite some improvement with the autostick put into half-auto-mode to use the 'safety upshift at redline'.
        The 392 is still a n/a engine and so every RPM equals power...

      us r/t challenger guys have known this for a while. the new 5.7's are making close to 400hp at the crank.
