No Mine Shaft for 2025!

The mineshaft rule actually works against you if you make a fast run. It takes away all of the runs for the weekend that could be used to lower the average. Not just the fast run.

This is especially bad at the end of the year.

I think every new rule idea submitted was shot down by the rules committee. Some that I heard that got submitted for Stock were allowing addition valve reliefs to solve the piston ding problem, and allowing pistons to be made with the smaller size ring lands so racers would not have to use spacers. Both got shot down. I'm sure there were more. The poll that was taken to see if racers wanted the indexes lowered had a very low percentage of eligible racers voting, and it was shot down.

What's the piston ding problem?

The idea of mineshaft is that the weather is stupid fast for everybody
Including you slow poke
When you have more than 50% of the field going 85 under that means it?s freaking fast out there

Mineshaft is more helpful than harmful

hey hey hey, no name calling lol

Anyway, fair. I can see the importance and necessity of a mineshaft rule. Maybe more generally, when the mineshaft rule isn't/wouldn't be in play, why do we not have AHFS at all of those races too? Like Indy, National opens, etc? Also, what defines mineshaft air and who makes the decision on when the air is too good?

By that definition Indy 2024 was a mineshaft. More than half the Stock field was over a second under.
The relationship between AHFS and indexes is out of whack

As you are not allowed to notch pistons for valve clearance, NHRA saw fit to make it illegal to allow your valves to do the job.
