1/4 mile runs....on the street...stock!

Well, it was time to take out the VBox and do some street runs on the Hellcat.
2015 Challenger Hellcat
8 speed auto
Stock P Zero Summer Tires, at stock 35 psi
(**Edit: I just checked my tire pressures and they were actually at 37 psi cold. Then I noticed that on the sticker in the door jam that 32 psi is recommended. So new runs are in order, as my tires were slightly overinflated. I may of done 11.6's the other night had I been at 32 psi instead of 37 psi)

595-610 miles on the odometer (first run was 595, last run 610)
Started with 3/4 tank of gas, 93 Octane Shell
70 degrees outside
91% humidity
3 feet elevation
Based on Density Altitude Calculator my DA was 938 feet.
Clearly not the best of conditions.
Had it been a month earlier, DA would probably be sea level with temps in the 50's

Car is completely stock, not a thing different from factory (except tint and clearbra). :)
I had not gone full throttle on the Hellcat until I had 525 miles on her and then I only did 3 full throttle runs from 50-120 mph prior to these runs tonight, so the car may be ecu learning still too.

Red Key of course
Transmission in TRACK
Suspension in SPORT

I did a couple attempts at the Launch Control and it resulted in too much tire spin, need to learn that system better.
So I decided to just do it the old fashioned way.
I am a seasoned drag racer with many other cars in the past, but first time in Hellcat.
All runs launched in 2nd GEAR, no launch control, just easing into throttle and letting transmission shift for itself.

My very first run was:
0-60 in 4.0
0-100 in 7.9
1/4 mile in 11.9 @ 127.2
Had a 2.2 60' time

Then I reeled off 3
11.7 @ 126.7 to 127.4
Best 60' time was 2.1 seconds.

So the best run was run #3 of 4
0-60 in 3.8 seconds
0-100 in 7.6 seconds
1/4 in 11.7 @ 127.4

Got home and decided to compare that to Car and Driver's time with their Hellcat and they did it in
0-60 in 3.6 seconds
0-100 in 7.6
1/4 in 11.7 @ 126
Their car had 2000 miles on it and they had better weather. Basically tied (and had better trap) their times and they do it for a living. LOL

11.5 @ 128 on the street, on street tires at street tire pressure will be a reality once car is broken in a bit more, I have a better DA, and get a chance to learn to launch this car a bit better.
On a drag strip with VHT prepped surface, 11.2-11.3's no problem on street tires (which is about what the pro drivers at Dodge got and stated IIRC) So overall I'm pleased considering these were my 1st attempts at 1/4 mile runs in this car.
Sadly weather is only going to get hotter and more humid (life in the south) in coming months, so may have to wait till fall to hit up drag strip around here to see if I can get those low 11's at 127-128 on street tires. Good times.

Before anybody gets mad, I went out of the city on a desolate flat highway (where I live, just above sea level, you can go 50-100 miles and elevation will change by no more than 10 feet). On this highway where I did the runs, there are no side streets, no homes, no buildings, and no cars in sight. If I saw a car coming, I pulled over and waited for them to pass, and get out of sight. Open fields on both sides of highway.
If anything was going to happen, I would not of hurt anybody else or anybody else's property.
Was as safe as I could be. Made 2 runs in each direction.

First of all thanks for the disclaimer as I have no issue under those circumstances. 2 lane roads with side streets with houses on any side block vision (deer here) and kids and isn't the place to get on it IMHO. Nice write up. I was running Sunday and a HC Charger made a few passes when I was in the staging lanes and all I could hear was 11 sumthin at 124 so not so good I thought.
