AHFS active for 2021 US Nationals
 

NHRA has announced that the Automatic Horsepower Factoring system will be used during the 2021 NHRA U.S. Nationals event. All runs made by Stock and Super Stock competitors at any time during the event will count towards class averages, and will be used to trigger index or horsepower adjustments

Well, there goes a really big part that makes Indy special.....at least to me.

Re: AHFS active for 2021 US Nationals
 

That will turn Class into the Super category's. Only exception will be instead of shooting for exactly 10.90000, 9,90000, and 8.90000's.... We will be shooting for 1.199999 under your index. Sounds like 1000 foot racing is back at Indy. At least it was cool while it lasted

Re: AHFS active for 2021 US Nationals
 

Wow. Disappointed to hear this.

Well on the bright side it will get some really silly
Combos sorted out.

Pretty sad the last several years the “race cars” that have qualified at the top of the list....

With all the gloom and doom these days, I am happy to see that we are still on the menu......

About Time.
No more mulligans

Re: AHFS active for 2021 US Nationals
 

And the hits keep coming.
Thank You Sir "May I have another"!

Re: AHFS active for 2021 US Nationals
 

As it should be. Not sure why they ever took it away. without HP adjustments and Tear down we are just glorified bracket racers. No more 2 second under qualifiers at Indy.

In 2008 I qualified #1 at Indy and took HP for it. and I'd do it again. If you want that spot, be prepared to pay the price for it.

Well that's because your brain is frozen!!:rolleyes:

I was planning Indy 2021, solely to run flat out .
Very Disappointing if true.

And every combo on the list had a very soft factor and deserved an increase.
