No Mine Shaft for 2025!

Herbie Null · 02-17-2025, 07:08 PM

The SRAC tried to bring back mine shaft rule this year, NHRA rules committee denied the request!! So let me understand this, no mineshaft rule at 100ft and all runs count, but at +4200ft at Indy the runs do not count towards the AHFS? �� unbelievable! Can anyone explain the logic here?

There was a rumor that the AHFS would be not be used for all class eliminations but I'm guessing not.

So Indy is the only place us southern boys can say “Hay y’all watch this!”

I hate the AHFS. I personally think that Stk/SS is a performance class and should be treated as such. ie; qualified field, lane choice to the lower qualifier, routine tear downs, etc. However, I realize NHRA has chosen not to go in that direction. NHRA has chosen the AHFS as a means to police the class. With that being the case, I don’t see the logic in waiving the AHFS at certain events. The system simply will not work as designed under these circumstances.

I did not see the No Mineshaft on the NHRA website.

Did I miss it somewhere?.

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?

wtf is the point of AHFS if it isn't employed at races where guys actually have to run their ***** wide open?
