10/10ths driving school at Putnam Park this weekend was an absolute success. I attended Saturday. Two things of interest. The temperature never exceeded 70°. Last year, at my first track event, my differential overheated. I could only run 15 minutes per session before the warning light would come on. (Another reason 10/10ths is my absolute favorite for HPDE events. I was allowed to run for 15 minutes in two categories so I could get my 30 minutes per session.)
After that occurred, I had the differential fluid replaced with high performance fluid. Even though the day was very cool, at my fourth of fifth sessions, at about 27 minutes into the 30 minute session, the differential overheating warning light came on. Of course, I slowed down and ended my session early. In the last session, it was only 20 minutes, and it did not overheat. By the way, I was again allowed to run in two sessions if necessary.
I’m going to take the car in and have the differential checked.
And this was rather interesting. On the front straight, I come out of the last corner in third gear and shift into fourth gear. For the first time, I watched my tachometer very carefully and shifted just before the rev limiter. When I did, my traction control light came on. Does that mean I was experiencing wheelspin?
I did achieve my fastest speed on the front straight (131 mph).
Yes, you were slightly peeling out or experiencing sliding if your car was not completely straight mine does it occasionally when I shift it right before red line. Oh, what an amazing feeling! Love the V.
I was absolutely straight. As far as diff it may be that I am running faster and the overheating is the result. At three prior schools after the HP fluid it never overheated. I guess I should be happy.

Re: wheel spin with shift?
Wheel spin actually happens a lot more easier than you would think...
For the longest time I thought I wasn't getting any wheel spin, until I start noticing I was leaving rubber on the road whenever I was using 75% or higher throttle in 1, 2, and 3 (I haven't tested 4th or higher).
I never get the traction control notifications just because I always drive with everything turned off.
