Re: Word is 1.15 under for AHFS at Opens and Divisional races
 

Was told the 2008 is the last year for the rotation of classes at national events. The end of the trial.

2009 all classes will run at all national events. Car count will be cut as X amount of cars can be run down the track on a given day within the time constraints. Logistical issues are just a fact of life. If you want to run a national you are going to need them grade points.

As far as I am concerned, I will still concentrate on using my shoe polish since we are under the index.

Mr. Buckingham,

You sound very much in the know on all things nhra or possibly some one is retro fitting the news for you. After cleaning your nose can you please tell me who will be discussing what at the PRI show? Specifics please!

There are rules of engagement that must be followed when doing statistical evaluations. Some are assumptions. Some assumptions are statistically significant, some are not. This is why no system is perfect.

However, you cannot have a valid system that is not mathematically accurate. If NASA did it the AHFS way, they would have missed the moon entirely. It is only the manual joy stick that keeps in on track. (The good people adding some sense to it)

One thing that is perfectly clear, you must correct to sea level or some other standard. Yes there would be some inaccuracies, but a 10.00 run at 5000 feet is not the same as a 9.80 run at sea level. Most racers have the software in their trailers to calculate all of this. It isnt that hard to do.

Yes if a set of numbers are found to be inaccurate, then you gotta throw them out. The statistical method of standard deviation can be found on any Excel Spread Sheet or any high school science book. It is the only right way to do things. It separates the individual outstanding performances from bogus HP and bogus parts acquisition.

Even doing it the right way is difficult, can you imagine the mistakes doing it the wrong way? I would say an engine family that averages 1.15(without sandbagging) under to an engine family that averages 0.7 is an egregious difference. If we have a AHFS, then how does this condition currently exist if it is working?

My guess to equalize these two would be about 70HP?(assuming 15HP a tenth?) How many 3-4HP adders would we do? How long would it take? I assure you there are many engines that fit this category and worse.

You do not need an Excel spreadsheet to do it. It is easy to do a computer program that would adjust the numbers based on weather conditions and actual track altitude. The computer program called Density, that was created by Pat Hale, can be modified to do so. Nevertheless, Pat sold all the program rights to the owner of speedtalk.com. NHRA should hire Pat Hale to develop a computer program to do the adjustments properly and scientifically, and take away the "Human Interest/Factor" from the adjustments.

Re: Word is 1.15 under for AHFS at Opens and Divisional races
 

Greg has it right and Bruce has it right also. NHRA is not going to do a darn thing that takes alot of time and manpower. Why do you think they implemented the AHFS in the first place? Why do you think they don't count runs that are not on the Q sheet? Nitro Joe has all the numbers . They are not that hard to find.
I'll say it again. Count all runs at Nationals . Forget Div's . You want your combo hit by somebody that is claiming the small cam motor ,when they really should be carrying 20 -30 more HP? Don't think it has not been done.

Re: Word is 1.15 under for AHFS at Opens and Divisional races
 

If the runs at the Divisional races are not going to be included in the AHFS,they why have any heads- up races at Divisionals?
Isn't the purpose of the AHFS to try and equalize the combinations,so if everyone worked hard on their combo,then theoretically it would be an even race?
If there is no AHFS at Divisionals,then just get rid of it altogether.When some cars run over 1.15 under with a 20 mph headwind in 4000 ft corrected air,I would kind of like to see how fast they could go at sea level anyways.I'm thinking several combos are capable of 1.6-1.7 under if they really went for the killer pass.Not legal,of course,but still impressive!

Re: Word is 1.15 under for AHFS at Opens and Divisional races
 

Asked and answered.
I'm sure you remember , being the veteran racer you are, when there were teardowns at Divisionals.
Again , it comes down to manpower and effort. It just ain't gonna happen nowadays.

Re: Word is 1.15 under for AHFS at Opens and Divisional races
 

Actually any simple program could do it or anyone knowing how to do spc methods and data entry. Excel has it or any other compute programs. It isnt rocket science more like High School Science.

Hey Mark,

You + Greg are both right.. The other thing that needs to stop is giving ANY HP without a teardown first to be sure they are legal... How many times were they torn down later and found illegal...But the HP aways stayed and never was reduced ..This should always happen any time you get HP added... Yes, all runs during National events should count... I think this would be a good first step..........Dave,
