I had been looking for some official 1/4 mile times on the car and I just haven't seen anything reliable. I went today to see what the car would do with me driving it.
Car has 3100 miles and is an 8 speed auto. I had never used or tried launch control so I only got it to work on my last of 4 runs. It was my best time but barely. I didn't give it any more runs to learn the track so maybe it would have gone slightly faster I don't know.
1st run (not showing slip in photo)
13.5
2nd run
13.33
3rd run
13.39@104
4th run
13.33@104 (only run using launch control)
Was about 58 degrees out on my last and fastest run. Only ran 4 times and was consistent enough I didn't think it would get much faster.
Basically all were at 104 mph or just hundredths of a mph below.
Even when the launch control wasn't activating I was power braking so seemed to have pretty much same effect.
I actually cut my best 60ft without launch control but best ET was with Launch control on the last run.
