It does. If you go 1.95 or more under the index you get hit 18.25%.

All class rounds count. It says:

"At events where class eliminations are run, all runs are included in the AHFS database."

It then says:

"Only the first round of class is part of qualifying and therefore is part of the "Q" database."

I assume the other rounds of class will be part of the "E" database.


Also, the way I read it, runs at national opens won't be put in the AHFS database. Only the automatic HP hit applies at national opens.

Thank you Toby.

Hi Toby,

I believe that the incremental increases in the percentage of increased HP only apply to a combo that averages more than 1.00 under the index and not the instant 3.25% hit.

If your combo's average is more than 1.00 under and the fastest single run during the review period is 1.49 under than the adjustment would be 8.25% for all cars running that combo.

On the other hand, I could be full of crap..

The way I understand it is if there is a run of more than 1.20 under it is an automatic hit and there is no need to figure averages.

If all runs for a combo are less than 1.20 and there are 2 runs of more than 1.00 under to trigger a review, then they go to the average.

If you look at the web page everything quicker than 1.20 under says "(immediate change)."

Toby, That's the way I understood it.

Toby,

I think that you are correct about the imediate hit, but are you saying that the combo would not also be reviewed at the end of the review period if the combo average was faster than 1.00 under?????

Would an immediate hit exempt the combo from the average????

It looks like the AHFS was written in NHRA speak..



"Once the need for an adjustment is determined, the following sliding-scale formula, based on a percentage of horsepower, is used to calculate the horsepower increase"


"The quickest run, by the combination being reviewed, is used to determine the adjustment percentage".

Yes, that's how I understand it. If a combo gets an immediate hit of say 5.25% there is no need to figure the average.

And the quickest run being used is if one car goes 1.21 under and another goes 1.51 under on the same weekend, the combo would be hit 9.25% instead of 3.25%.

Or if one car goes 1.01 under and another goes 1.11 under and after the review the average is more than .850 under, the combo will get hit 2.25% instead of 1.25%

It is kind of confusing, but I think I'm getting the hang of it.

Bob,
For some unknown reason once a combo gets a new HP Rating all previous runs for that combo are wiped out. The data collecting starts all over at the new HP rating. My thinking is the runs should continue to be gathered and be reviewed at the end of the year to see if the " possible runaway combo" is still a running away. LOL
