Here is a plot of the telemetry from the last time trial on the road course at Spring Mountain - three laps worth:
The green line is GPS Speed. Maximum that I saw was only 104 mph and from the data it was at under 6000 rpm midway down the back straight. I know that I was babying it (especially with my brake problems) but darn, I didn't think that I was taking it that easy.
The blue line is engine RPM. Like I said above, I was under 6000 rpm most (all) of the time. Lots more legs left...
The red line is lateral G's. Maximum positive (right) was 1.4, maximum left was 1.
It's interesting to look at it after the fact, it shows me two things... one - I was being way to easy on it and two - there is a lot of potential left in the car.
