Racing Experience at New Hampshire Speedway ?

I am doing a racing experience next week at the New Hampshire Speedway, I am Stoked!! I am doing 36 laps (per my pakcage). My question(s) are; has anyone done this at this particular track? If so, what was your top speed and did you have to down shift going into the turns? I haven't driven a stick shift in about 5 years and though once you learn you never forget, I am still a little intimitated by the whole experience and don't want to stall out!!! I've been to this track to see the Sprint guys and know their top speeds are around 130mph as the track really has no banking so I was wondering what I might top at. Thanks for your replies...
