Day 2 – 30 Days of Racing in a Row

My goal today?

Well a pre-goal, was to actually drive.  The changes I made (stopping OneDrive from syncing, installing the latest updates so they weren’t downloading in the background and not having a video uploading on another device) all resulted in no performance issues at all.  Yay!

The real goal: Drive like I do in real life – putting down a string of consecutive and consistent laps.  I’ve found in the past in iRacing that I go off A LOT more than I do in real-life, usually having multiple incidents with walls in a given practice session.  That’s not what happens in real life and while I am not driving anywhere near the same car, I believe I should be able to drive in the virtual world as I do in the real world; safe, consistent and somewhat fast.  🙂

After a day more focused on setup and updates on the machine, my goal was just to put down a true initial baseline of what I can do in the Mercedes AMG GT3 and Road Atlanta.  Ideally, I wanted to drive the entire 60 minutes without an issue but I was only able to make it just past 30 minutes with no crashes. The good news was that I improved my personal best AND I put down several laps within .5 of my personal best, clicking off a consistent string of 1:22.xxx lap times and while trying different things.

I wanted to use this baseline of data to be confident in what I could do when analyzing the data with Virtual Racing School data packs.

22 laps without crashing! Not bad for not driving as much as I wanted to the past 6 months.

Lessons Learned

    • Pareto lives!  I am down 2.197 seconds from my reference lap and one segment alone accounts 0.809 seconds, almost half of the lap time.  Two segments (4 and 7) account for almost half of the delta.

  • By default, in testing, a car starts with a full fuel load – in the Mercedes AMG GT3, it was 30 gallons.  The car in the reference lap was running with about 10 gallons and 9 gallons in the lap I am using for reference.  That is a ~15 gallon and 90 lbs. difference.  THAT IS HUGE – though, I still have much more work to do aside from losing car weight.
  • The data exposes all – the major theme of comparing the two laps is clear.  I am braking too hard for the most of the significant turns where I am losing time and then getting on throttle sooner and harder than my rabbit.
    • I need brake slightly sooner, lighter and carry more speed through the corner and this will require coming on throttle softer.
    • This is consistent with what I’ve seen in real-life, comparing my data with a super fast driver like Olivier.

One thing I am going to work until I can get it

Segment 6, which includes turns 6 and 7.  Brake sooner, lighter, carry more speed in, know that mid-corner will be not as planted and I will have to be more gentle with throttle application on corner exit, because I’ll be carrying more speed.  The goal is still to get to throttle as fast as I can but I’ll be more at the limit.
