Nothing catastrophic. I made 11 runs and had competitive times. On the last two runs it stalled out just after I crossed the finish line and let off the gas. It had to sit about 15 minutes before it would crank and start. It drove onto the trailer at the end of the day, but had started popping and misfiring. I'm going to drain the fluids and pull the sump for a look, but I think it's done now.
It was Awesome!
