First time drag racing, e55
I had the dampening set on comfort, transmission set on sport, and left the line with the revs around 1100 rpm. I didn't do a burnout prior to any of the runs, and was in the staging lanes with the car idling most of the time for around 30 min wait for each run. Had the traction control on, and floored it from the line. Had 3/4 of a tank of gas.
Kind of disappointed as I thought I'd be in the 12's. My thoughts for my next runs in a couple weeks are:
1. Rolling onto the throttle instead of flooring the pedal from the start.
2. Going with a quarter tank or less.
3. Shutting the car down and rolling it in neutral thru the staging lanes.
Getting a service done at the dealership prior to going as well. I figured being stock my trap speeds should be around 112-118mph from my lurking and researching on this site and others. I was pretty consistently running around 107mph as shown below.
Thoughts are either the car was pulling a lot of power due to TC and me mashing the pedal from the start. Or else possible higher IATs due to an intercooler pump not working at optimal efficiency. Going to test the pump and get some IAT numbers in the next few days.
Any thoughts/advice/concerns from you knowledgeable gentlemen would be greatly appreciated!
Density altitude calculator came in at 1880 ft. I'm car #255 below.

Thanks for checking it out!

Yeah car #254 up there is my buddy's 2011 S4, and he was talking a lot of smack so I'm trying to see what I can do to make sure to beat him next time ha. His best run that night was a 13.27, so I figured with a little more practice I should be able to be a lot quicker than that.
Perhaps since your DA is 1800ft above sea level may explain why your car turned in what your think are poor times? The first give away was your buddys 2011 S4 which is supercharged. Granted it has AWD but under ideal circumstances should be doing high 12's.
Ive looked at other cars and they are just as slow
For instance a v10 m5 turned out a 13.8 1/4 mile time on street tires. A gallardo turned out a 12.8 1/4 mile time with e gear.
Maybe try another track where your a lot closer to the ground.
Also aren't you guys on 91 octane?
STICKY REAR TIRES A MUST!!! They would cut a 1/2 sec or more based on your 60'
