No none of the teams got any of their money back. The race's reputation, and Mike Worrells, have been destroyed. I believe the general theory is that Mike had used the money that came in to pay previous debts and never had all of the sponsorship in place that was needed anyway (this is from what I got reading the forums - I have no association with anyone involved, just a fan of the race).
This is a very sore subject for a lot of the people on the list and many really don't like to talk about it or bring it up.
