I only run a couple hundred RPM higher at the end of the straights at
RA than at VIR or Atlanta. With a 4.1 and OD and 60 series tires,
I'm at 5300 to 5500 coming into turn 5 and if I take the kink right I
am about there going into Canada Corner. I think I was in the 5200
to 5300 range when I was battling you on the back straight at VIR.
You should be fine.
