AHFS Updated

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

"The class review revealed that K/SA had a class/engine average for the combination in question of 1.101-second under, therefore surpassing the 0.850-second-under requirement and signaling a horsepower adjustment for all 305/215/241 FI Camaros."

Sounds like 1.01 trigger, and the average has to be faster than .85 under for a hit.

Sounds like everyone is getting the drift. Also a racer that runs two runs between 1.00 and 1.19 at the same event triggers the review.

Except when they do it only in qualifying. Say a racer runs 1.05 under and 1.03 under during qualifying, that only counts as one trigger since only the 1.05 under run shows on the final qualifying sheet.

I just keep learning about this! Last year I was told 1st round of class was the only class round that counted. That never did make sense to me. Also did not know only the fastest qualifying time counted. Used to be just Farmer's call. LOL.

The data from before the hit is irrelevant. Once it has been hit, the factor has changed, and the previous data no longer matches the current combination. How would you accurately correlate previous data to a car now running heavier, or in a different class, or both?
