6.4 hemi 392 runs 12.44 @ 110 mph in bone-stock 2011 Challenger SRT8

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.

Re: 6.4 hemi 292 runs 12.44 @ 110 mph

from what Im reading the 392 is a beast above 2000 rpms and really maintains peak tq throughout the powerband. the same Chally with the 6.1 ran a 13.4 stock....so if they cut 1 full second with the 392 in the Chally...will it cut one full second on the 2012 SRT Jeep as well? That would put the Jeep in the 12.1-12.3 1/4 range. I know....it all depends on drivetrain and what is used in the Jeep SRT8...but this motor really means business and seems more well suited to the SRT vehicles than the 6.1

Re: 6.4 hemi 392 runs 12.44 @ 110 mph

geez, if the 6.4 improves upon the jeep like it did with the challenger, that will def. be the fastest production suv. and its NA. silly germans using twin turbos...dont get me wrong i played with the turbo on my old evo and turbos are fun and it was stupid fast for a 4 banger, it killed the jeep by bus lengths, but i ran into more fricken issues with that thing in the 8 month span i had it and i havent even had a single issue with the jeep at all. these pushrod v8s are the ticket.

Re: 6.4 hemi 392 runs 12.44 @ 110 mph

Great news, spot on, just what I expected

ANYWAY, if anyone cares, I took a ride in the new 392 Chally the other day. A friend of a friend had one so I had my buddy call him up and come by my place just to check it out. A few minutes and some bs'ing later were in the car and Im at the wheel feeling like a 5 year old kid again.

First thing to note this new 392 is way louder and more rumbly compared to the 6.1 from what I recall. It just sounds and feels much more menacing. So as soon as I got to a nice open street (consider this is in a city grid- Philly) I put it down and boyyy did she move. She pulled out hard noticeably harder than the 6.1 Chally. I was really impressed with the power and everything else was the same as the old. Good ride and stopping power is still very good. The seats were very comfortable but look much slicker than previous models imo. Guy had the blue and white options, metallic blueish with white stripes, the thing looked sick. The wheels are the deal maker imo, they looked SICK!

All in all sweet ride, the motor is NO JOKE! Cant wait to see how it pulls in the Jeep, hopefully its the fastest yet again due to some nice AWD
