Just got back from my first track event and here is some data.
Tires were pumped last night to 35 F and R. Garage temp of 65 or so. By the time i got to the track today (1.5 hrs) fronts were at 39 and rears at 37.
Tire PSI increase by session (I wasn't paying much attention to rears so those may not be 100% but should be right about there - these are 20 min session):
Session 1: 41F 37R
Session 2: 42F 38R (Learned how to brake, after i was done the brakes were reading 470) ECS not completely OFF
Session 3: 44F 39R ECS OFF (Brakes were smoking when i pulled back in - forgot what they were reading - somewhere in the 600's - my bro's '17 STI was also smoking up front and his were in the 900's if i recall correctly)
As for the tires - w/ the heat gun they were reading 165-175 after session 2.
I didn't use chalk, wanted to and everything, but at the same time didn't want to worry about it that much. You can see something was happening to the sides but i can't believe that's because of them rolling. To me, it doesn't make sense. Overall their condition was ok and you can clearly see the edge to which they were pushed to, which was in line w/ where i wanted to see them.
I'm super tired. Figured i'd post this before i cool off and forget about this.
The car is a GTI, w/ apr Stage1 and CTS FMIC intercooler. I recorded some data via torque app during my last session so can't wait to see how the intercooler performed. Wish i knew exactly how much timing was being pulled and at what efficiency was the car performing (HP/TQ wise) at. Wonder what difference the RS7 spark plugs would have made - bought those just in case.
In short: tracking this car was ok. I have nothing to compare to it to besides auto-x events which are totally different. I feel like i can get as much fun on my bike in the woods. Maybe it's just me, or the GTI needs upgrades left and right where i feel like we're one. I wish i had an SS 1LE. Something NA and designed for this type of driving. Hopefully for my next time out i will finally get to installing my bilstein b12 pro kit (been sitting in my garage since May of this yr) for little improvement in the handling department. Setting up proper alignment and having a sway bar or two would probably help elevate the car from today's condition.
