He is out of Austin and does all the racing circuits.
I saw an article posted on one of the forums one day that was from the Austin American Statesman that quoted him heavily. I remember, it was before the movie with the slammed imports came out - I forgot the name.
You should be able to find out more about him by doing some searches online.
And yes, he is one BAMF with too much time and $ on his hands. I have heard of his cars and seen some of those videos. Wow!
