"An important thing to note also is that he said they did not start getting good times / hookups until they turned the stability control completely off. He said once they got that off (which required them to hold the button for 8 seconds), then they started getting good runs. So the car was in track mode and stability control was turned completely off and this was a require,ent to get the car to start hooking up properly.
Driver confirmed that he put the car in track mode and turned stability control off. No other changes to suspension.
Launched as close as possible stalling it to 2000 rpm. Launch control NOT used.
Lastly, the driver used the paddles to get the best times out of it!! His shift rpm was 6200 RPM when he hit the paddle." ~cerino2000
Interesting to note that the driveshaft is just 'slicks and race fuel away from twisting! Detroit overnighted a new Driveshaft for the twisted one.
Here is a user picture taken the night of the 1/16/2015 race by another forum member of the modified Black Hellcat. They posted it around 9:20pm that night as well as talked to the owner who confirmed MS109 race fuel and tires as the only mods.
Hehe, the amount of skepticism is hilarious and amazing how much buzz this is creating in the performance car world.

Your mind whispers to you.."It cant be coming that fast ..the calculations don't add up.....don't worry....it's not real." But your eyes....ohhh your lying eyes.....see the demon...about to have you for a snack.......
Hehe sorry, just enjoying the moment that a Hellcat, at 4449lbs, can run a 10.48 @ 133mph.

Based on the weather data for both days, the wind conditions were calm at the time they ran the 133 mph run on 1/6/2015. For the 126 mph run on 1/5/2015, winds were out of the North to South at 10.4mph.
The track is a Southward to North-Westward facing track meaning both runs would be going into the wind, except there was no wind on the 1/6/2015 133mph run. Between the better 60ft and no head wind, that could account for another 0.2s in the 1/4mi and definitely account for the big gap between final ET MPH.
No doubt, when they ran the 133mph run, conditions were damn near perfect!
