Blown tire @ 120mph....
Wow, you are one lucky SOB! Were you rolling video when it happened?
I'd be real curious to hear what Dunlop says the cause was. My uneducated guess is that it was rubbing something on the inside suspension. I would take a close look at the other side for comparison.

just remembering when my tire rubbed , it was pretty evident, loud, and you couldn't miss it.
if the op didn't hear it, or the instructor, that says something.
First few pics showed relatively full tread.
with low pressure he might have rolled over on his sidewall and picked up a bolt. hard to say. but even there, he gave good account of his pressure so that is out too.
I just felt I was wrong in my first post and was letting the air out of my post.
I guess I should have said, forget what I posted, I don't know... still don't.
Hey man! I WASNT!!! uhhh.... i had the video camera in the car and mounted up ready to roll but i decided i wanted to take an instructor with me on the first session so i didnt turn the camera on as it was right behind his head... I had a car right behind me also and he got a front row seat to the blow and spin... but again he also didnt turn the camera on for the 1st session either!!
lol uhh i was so pissed!!! I actually just pulled all the tires and rims off the car and will be looking at them today to see if there are any areas on the inside that were rubbing...

Thanks man, yeah this was my first experience on an actual track. Like i said i have autocrossed on that track many of times. Thats good to know though about tire temps going up around 10-12 psi. Im used to 2-3 in an autox lap but theres alot more demand on the tires. Thanks for the advise and next time ill run around 30psi and monitor it.
And I didn't drive very hard that time. 
I've learned than in the summer (90+ down here) I can now expect up to 12psi increase in the fronts depending on the track. CMP this weekend was a good bit cooler and I was seeing around 9psi rise.
Just make a habit of chekcing your pressures hot right off the track. If you watch the serious TT guys, most of them will not even take off the helmet, they pop out of the car and grab the gauge.
Also, right before you go back on the track at each session check you lug nuts with a torque wrench. Do this when the wheels are cooled off. If you do this while everythign it hot, then the studs will contract as everything cools and you actually end up seriously overtightened.
Hey, no prob. First event I went to was a March event very cool. First time I ever drover on a track. Came in and my instructor had me check the tires (hot) and the fronts were at 45psi. He then explained to me what was going on.

Do you see how F'd up that wheel is? I don't think laying it down is an issue.
