I was reading the latest artical of Mopar Action last night. And saw that they spent some time with a 2011 challenger 392. I believe thay said that they were able to make 7 pass on a track with the stock tires. And averaged 12.38 in the 1/4 mile. Their fastest time was 12.29. This was a 6speed also. Very impressive numbers from this thing. It is going to be a beast.
