Do runs at sportsnationals count for factoring horsepower

Re: Ahfs
 

Yes. Tom

Re: Ahfs
 

Absolutely! Jim:p

Re: Ahfs
 

I guess runs count at National Opens too? Anybody care to clarify?

Re: Ahfs
 

Not in D7.................Opens have combo races with no heads up or fuel check.
We do things a little different out here................................

7423 The way i read the rules, runs of 1.20 under count at all Nhra events. average`s of runs count at national and division points races. Sportsnationals are like national events. Tom

"The AHFS is used to review and evaluate runs in Stock and Super Stock for possible horsepower adjustments. The review is conducted twice per racing season. The two reviews are compiled individually so the data is not cumulative. Runs included in the AHFS database are limited to final qualifying runs (Q data) and all elimination runs (E data) at all NHRA National and LODRS events. (At events where class eliminations are run, all runs are included in the AHFS database. Only the first round of class is part of qualifying and therefore is part of the "Q" database.) The "Q" data and "E" data files are the official data gathered by the NHRA timing system and processed through the NHRA Information Technology department. NHRA "Q" data and "E" data are the only data files used for the AHFS.

The first review period includes data from National and LODRS events 1 through 11 and the second period includes runs from events 12 through 22. The following procedure is used in reviewing run data:

Final qualifying, class eliminations, and elimination runs of 1.00 seconds or more, under the index, at NHRA National and LODRS events will trigger an automatic review. (The combination must make at least two runs of 1.00 or quicker before a review is triggered to prevent a "one time fast run" from triggering the system.) In reviewing runs of 1.00 or more under the index, the database of runs for the engine combination being reviewed are put through three screenings as listed below. The screenings will look for an overall engine family average or class/engine average faster than 0.850-second under. Runs of .350 and slower are not included in calculating the engine or class/engine averages.

Runs of 1.200 or more under the index will be reviewed and adjusted Tuesday following the event. Runs at all NHRA events, including those at altitude factored race tracks, are included in the 1.200-second-or-more-under analysis. This is done to better react to any out-of-line indexes or under-horsepowered combinations. Therefore, at all such events, a horsepower adjustment or index reduction will be initiated Tuesday following the event.
The decision to adjust horsepower or to reduce the index will be at the discretion of the NHRA Tech Department."

In other words, your fastest qualifying run and all eliminations runs, whether for class or for the eliminator, at any National Event or LODRS Event counts toward the AHFS. All Sportsnational (3) events are considered National Events Jim
