I was backing off a little most of the time, on the straights you would catch Boxsters and Caymans, that were faster in the turns than I, on pure grunt and there was a lot of passing going on by P-turbos! I sucked at Oak Tree, so would go aorund it in 3rd instead of 2nd. I was getting 145 on the speedo (139 real?) on the back straight, and probably ~125 on the front straight as I was conservative through The Hogpen.
Please note that I have RPI scoops on my car, so that will have added huge amounts of power!
