Question. I've seen this brought up a couple of times and it got me to wondering. I understand that this event requires entrants to abide by standard NHRA safety rules but what's the criteria for rules that affect performance? Do they follow NHRA rules or can you run with less weight, more wing angle, more than 90% nitro, blower overdrive, laid-back headers, etc.? I wouldn't think so but I'm not sure.
