So fellow forum members are gonna head to our track which is a short distance above sea level. Bout 6000' above.

See how we run.

raceyBMW bringing his supercharged E92 M3
tnd720 bringing his tuned M235 xDrive
Lemongrease bringing his X3MC
And I'll have my X3MC as well.
Got my dad to bring his c43amg too

Update:
We hit up the drag strip last night. Was great weather so was hoping for some good times for all of us. It was however busy.

Track stats:
- Track elevation ~6000 ft above sea level
- DA ranged from ~7600 - ~8000 (very typical)
- Temps ranged from 69F - 73F

Observations.
- The X3MC does not like to sit at altitude. We had to wait between 30-45 minutes between runs and best I could tell the IAT's were 114 degrees and climbing.
- Launch control simply does not work as well with high IAT's and not much airflow before runs. Sitting in the staging lanes too long because 200+ cars just doesn't bode well.
- Dragy, I was skeptical but damn that tool is spot on. Within hundredths of the slips.
- Dragy DA here in Colorado is bonkers and not accurate.

So, those are my excuses. Some will probably say we are still not doing it right, but Lemongrease and I both had the same issues. The car just won't launch above 2300-2400. So 60's are horrible, and the ET's show it.

That said, I was very curious to see what the darn thing could actually do with an open road and proper airflow. You'll see my Dragy runs from this morning confirming what I knew the car could do even at altitude. DA where I was this morning was 6800 approximately.

We are hopeful that the fall running, temps will be better and can have more time to cool down and not have such high IAT's. I believe the car just does not want to build enough boost when particularly warm at our altitude.
