Most of you know I'm the ChallengerFest event owner and organizer and I've dealt with this very issue over the past few years since 9 second Hellcats are almost the norm. I tell ANYONE that phones, emails, texts, Instagram, FB message, and it's in our official event rules that your car must have proper NHRA safety equipment to run the times it runs. Period. That way there is no question. I don't make the rules nor enforce them, that's on the track as that's what I pay them for. The track has never questioned anything, but I don't want to be put in the middle of a debate or have someone drive across the country and get pissed. Seems simple enough to me to just make it clear up front. Then if you show up and things are lax, have at it if that's your prerogative.
Also, I've never seen a track immediately boot someone. A warning is typically given first to slow down. You can still race, just change the tune, let off early, whatever. It shouldn't be that big of a deal, that is unless you waited all year for November weather at Atco to set a new PB and drove across the country to do it which sounds like the case here. If you chose to ignore the warning, BYE. I have zero problems with that.
That's my .02 cents no change for your 5.
