Well there are 3 guys that got new SSs on the Chalenger talk forum, went to the track and none of them ran as fast as the mags say.
Yes it all comes down to theriver somewhat.
But these cars do 170+ top end and high 12s stock with F1 tires and a good driver stock if it is a SRT. We also have many documented cases of 0-60 times from 4.48 to 4.7. My best has been 4.62 and I have run a 13.35 in the 1/4 at elevation in Bil MT. That was before I did a few misc mods to the car.
