NHRA and AHFS

As the result of runs under the Automatic Horsepower Factoring System (AHFS) 1.20-second under policy at the NHRA FOUR-WIDE event, the following changes have been made.
BBC396/375 / 399 / 412 and LT1350/285 / 346 / 358


Dear NHRA administrators.

Following on your latest Automatic Horsepower Factoring System (AHFS) update, many of us were under the impression the cars involved had to go through teardown before confirming any AHFS adjustment.

But I was told there wasn’t any teardown at least in the latest update?

May I bring to your attention the following; when someone (like I did last year) decides to make history and tries to establish a new record in the sportsman category, this same person knows and is willing to pass teardown for the new record to be recognized by all. There is only one person involved and one car with no effect on anyone else but by respect to all competitors and to make sure all the rules are well respected, NHRA goes through the time consuming experience of teardowns all across the country.

Now comes this AHFS moment, something that affects many many racers in the indicated classes that are fighting every week to gain thousands of second’s improvements here and there to better their chances in winning rounds and programs. And here you are, with this AHFS policy that automatically penalize an ole bunch of us without any kind of inspection to validate the conformity of such performance, no teardown what so ever and we all pay the price of this laxity!

For many of us, under the impression teardown occurs before any AHFS adjustment, such attitude is nothing short then a lack of respect of NHRA’s own rules and policies and a serious lack of respect to NHRA’s sportsman racers.

I understand some places do put racers through teardown to validate an AHFS adjustment, and some don’t, would you accept such approach towards establishing new records entries?

It’s never too late to correct what’s wrong and make it fair for everyone and be assured I’m not saying the racers involved have done anything wrong.

Thanks for your time and actions.

Re: NHRA and AHFS
 

Did you submit this letter to anyone at NHRA and if so did you receive a reply?

Re: NHRA and AHFS
 

If you set your record at a points race and went 1.205 seconds under the index, what would happen and who would it affect?

Re: NHRA and AHFS
 

What had happen was?

Re: NHRA and AHFS
 

1.20 under always applies. Even in mineshaft the only thing that is lifted is the -1.0 trigger.

Re: NHRA and AHFS
 

I knew that, not

Re: NHRA and AHFS
 

Yes I sent that to Dave Mohn this morning and no reply right now

Re: NHRA and AHFS
 

What's a letter gonna do? It's done. 1.20 is the law nhra only tears down at Indy

Re: NHRA and AHFS
 

JMRACING STOCK / SS 1999

I agree with you, it's the law and please, make it the same law for everyone, in all circumstances.



Why checking fuel and weight? Take it for granted that all is well, but that's not the way NHRA works thank God.



Working with the highest standards of technology and tech people to enforce all rules & regulations and fairness to all racers in all aspects of this sport and acting in total disregard when AHFS time comes is not only questionable but in total opposition to its responsibilities when so much is at stake for so many people.


What’s a letter going to do? Can’t tell but NHRA’s administrators’ needs to identify the irritants of this organisation and you might change your mind when your turn comes!

Re: NHRA and AHFS
 

It sucks, I understand. I got 12hp before I turned a tire at the track. From the looks of your avatar, you got some too. I think your letter has great intentions but I honestly don't think anyone in Glendora cares about S/SS and it has shown for a long time. My hat's off to them over the off season for breaking the FS cars out, I really didn't think it would happen. We have been weighed, we have been measured and we have been found wanting. Good luck with your endeavor, it is a very daunting task.

Re: NHRA and AHFS
 

But yet you can set the C/SA record at -1.40 at a national open with no affect on HP factor.
So. -1.20 gets you HP at a national event but -1.40 at a national open no HP. Sounds like a good system to me.

Re: NHRA and AHFS
 

I'm pretty sure that if the conditions are mineshaft, per the new mineshaft rule, runs of -1.20 under the index do not get automatic hp. I could be wrong, but that's how I interpret the rule. It is supposed to prevent getting hp in "mineshaft" air.

Re: NHRA and AHFS
 

Look at the 11th paragraph of the AHFS. Runs of 1.20 and above always count.

Re: NHRA and AHFS
 

1.20 applies except at National Opens. The mineshaft is only for the 1.00 under trigger. That rule you read must be in Dutch Arabic or Roman Numerals or something.

Re: NHRA and AHFS
 

" No runs made during National Opens, test and tune, time trials, or races within a race (i.e. Jegs Allstar eliminations, Stock / Super Stock Combos) are included in the 1.200-second-or-more-under review or adjustment."

Re: NHRA and AHFS
 

I never actually read the whole mine shaft rule, but you would think mineshaft is mineshaft and no runs would get penalized! What does mineshaft mean for Comp? Can they still get a permanent hit if it's mineshaft for them?

Re: NHRA and AHFS
 

1.33 under during qualifying at the Jegs Allstar no AHFS!


If the racer uses the 1.33 under qualifying time to get on the sheet for either Stock or Super Stock eliminator at that same national event the AHFS will apply. That seems fair.


If that scenario works for the All Stars, why does this not apply to the Factory Showdown cars?


Let the Showdown put on the good show without AHFS, but when they use that same qualifying time to place themselves on the qualifying sheet for the eliminator let the AHFS apply.

Re: NHRA and AHFS
 

Comp cars can still get a permanent CIC in mineshaft conditions, but the trigger moves from -0.61 to -0.66. So a -0.66 run will be a .01 permanent hit, -0.67 will be a .02 hit, and so on.

Re: NHRA and AHFS
 

This sounds like a much easier and better idea. If mineshaft conditions exist then raise the hit. EX: 1.05 instead of 1.00 1.25 instead of 1.20 Or whatever increase seems reasonable. Then let AHFS does its job.

To me if your running that fast in any condition mineshaft or not don't you think motor should get HP with any combo? I do. It must have been a soft combo that was protected and potential was shown.

Im speaking in general and not finger pointing any 1 particular combo

Re: NHRA and AHFS
 

Bryan, Comp racers get a 'nickel' extra to play with. If the first car in the bottom half of the field in qualifying (#17 in a 32 car field) is -.61 or more under, the mark for a permanent hit goes from -.610 to -.660. Maybe S/SS could get something similar (i.e. -1.25 or -1.30 for an automatic hit).
