Jim it has been a long time since i have run my mustang at Road America. I dont have much experience road racing. I have run in some open track events there. I ran in an full track autocross and got a 3 place. I was in a class with r model type shelbys and clones. Asked some of the other guys how fast they were going down the long downhill straight. Was told they were running 150-160. They were running 3.89 to 4.11 gears and turning 8000+. My car was limited to about 135 because of Rev limiter set at 6500 and 350 gear. Not sure i topped it out ever on the track because I am a chicken. My car i run a non overdrive 5 speed and I never got lower than third gear on that track.
