Sorry to be late to the party, but I learned of this topic, decision and controversy this morning. My perspective is skewed. I just got back an engine rebuild and haven't even started it yet. With totally unknown HP/TQ, I find it disappointing that I now must spend more money and more time to find out if I have a possible DQ motor.
I don't really have an issue with the rule, but the DQ sanction troubles me. I prefer an appropriate penalty of reward weight for one or more future events as a sanction. As a part of proper preparation, the front runners must go to the dyno before events to assure close to the threshold, but cannot risk going over. So more time and money on dynos for anyone with podium aspirations, or even point accumulation needs for qualifying for Nationals. Then there are undeniably dyno variations, which forecast for some pretty ugly arguments if the outcome changes a season. So the prudent prepared racer should dyno on the equipment used by the track that they risk the DQ measurement on. Still more time and still more money. If the sanction is weight, you get to live with it.
Racing is a money and time indulgence for me, and any rule that adds to both is not a good rule in my book. But with a less draconian sanction I think the (good) intent behind this rule can be achieved, without the harsh and potentially surprising consequences. I will be lucky to make enough events in 2013 to qualify for Nationals, which I would eagerly attend. Risking a DQ I feel is too draconian and may knock me out of Nationals. But with a weight (reward) I can still compete and take my lead lumps. And then at least I didn't have to take another day off work to go to a shop, dyno the car, and hope their dyno matches someone else's.
Thanks for listening.
