Jeff, I liked the vid - car sounds good! That was the first video I've seen of the track since the Billy Mitchell bridge was taken out.
Here is one of my race vid's from RA (last August). I think I read you were in the 2:4x.xx range - is that right? My best is a 2:39 lap there - but I do it with 285 RWHP (in a 3000 pound Mustang).

I played the two videos side by side. We are pretty close!! I'd say your top speed is 10 MPH faster than me. I'm making up the difference under braking and corner speeds, especially in the Carrusel.
BTW, There was a Noble in my race, probably the same one you saw there - damn fast car. Sux to loose a race to a car with license plates....
