So, after a blistering hot weekend at Autobahn CC, I observed a couple of interesting things:
1. Temps were about 10-12 degrees cooler running the normal Black key instead of the Track key. I am baffled by this.
2. Even with temps on track cresting 107 degrees, according to my thermometer, with better than 50% humidity, I had no overheating on the Black key at all. I have the 302s grill and nothing else of note to mitigate heat that isn't stock. Even had a 35 minute session at the hottest part of the day.
3. Every run I made with the Black Key set off the "Service Advancetrac" error, with TCS, ABS, etc lights going off. Didn't cut power to the car, activate brakes or anything so I ignored them after the first time and just finished my run. Each time, it cleared after shutting down and restarting, no problem, so it was just the yaw sensors I think.
4. One other Mustang guy at the track had seen this before, but after my 3rd run session for Sunday, my bleeder valve on my driver-side front Brembo backed itself a little out, leaking some brake fluid on the caliper and rotor. Which promptly caught fire. A quick squirt from the extinguisher put it out, and all is well. I had bled brakes the night before, and the brakes had been rock solid for the first two runs of the day. Never personally seen that before. I pulled the caliper off and inspected it - seals etc. all were fine, we caught it quickly. I simply re-tightened the bleeder valve and all was basically well after another brake bleed and some cleanup. Unnerving, but no real damage.
What does this tell us? I don't know - this is not an interpretation of my experiences, only a relay of what I saw and what happened.
The car was fast, was a great run weekend. There was another Boss to play with out there, and lots of fun with Porsches and Vettes to be had ;D Can't wait to hit Autobahn again, it's an awesome track.
