AHFS Changes:

Re: HP Changes Posted, AFHS Changes for 2015
 

Hmm, if these don't go in effect until Jan 1, 2015 then my math says I should have gotten 3hp back this last review.

Re: HP Changes Posted, AFHS Changes for 2015
 

This Mineshaft rule will almost never come into play in Super Stock! Look at all of the races in "good air" last year, where has the top of the bottom half been .850 under? I saw Indy was "mineshaft" but that's about it.

My suggestion was, "if it's mineshaft for Comp, it's mineshaft for all categories!" Others had that opinion also, but I guess the powers that be thought that would be too simple.

Re: HP Changes Posted, AFHS Changes for 2015
 

Does this mean that the Indy U.S. Nationals will be considered "mine shaft" conditions? It took more than .850 under the index to make the 128 car field.

Re: HP Changes Posted, AFHS Changes for 2015
 

just glad I don't have to keep track of who is getting hp'ed anymore way to confusing.

Re: HP Changes Posted, AFHS Changes for 2015
 

Marty, I would say yes. Only the 1-.200 (excluding FSS) penalty is in effect there, the way I read it.

Bryan, I would agree. Mineshaft for Comp = mineshaft for everyone. But Comp uses -.61 under for the first car in the bottom half (11 in a 20 car field,. 17 in a 32 car field, etc). I'm not sure what number would be fair to use. -.61 would make a lot of races 'mineshaft'. -.85, like you said, only Indy might make that cut and 1-2 others. It took -.882 to MAKE the show at Indy in Stock. Not sure what a fair number would be; maybe -.75. Just some more fun stuff to debate before Pomona.

No HP hits at Indy..means no HP hits for factory cars.
Got it ? Good

Re: HP Changes Posted, AFHS Changes for 2015
 

I got it Mark!

Re: HP Changes Posted, AFHS Changes for 2015
 

What I meant was if the "Mineshaft" conditions are met for Comp at a race, then Stock and Super Stock should be considered mineshaft also. So if that Comp number is -.61, then regardless of what the bottom of the top half runs in Stock and SS, they are still mineshaft. But there would still have to be a minimum number for Stock and SS for when Comp is not contested. I looked at races like the 4 Wides, where there were definitely mineshaft conditions, yet the -.85 number was not hit.

Re: HP Changes Posted, AFHS Changes for 2015
 

Byron, I know super stock is going to be tough. Hopefully they will make a change. This is a step in the right direction. The way I like at it, races like the sports nationals in Belle Rose and some nationals with class will benefit. Last year the split for stock at Belle Rose was - .817. I think some people that may have not wanted to try for class to avoid triggers may turn it up and it may raise the numbers a bit to make more races "mineshaft."

Re: HP Changes Posted, AFHS Changes for 2015
 

No change in Stock for Ford 300 150 190 1993 F-150
I Realise nobody is running it, but 190hp for an inline 6?

Too bad, would be interesting.

Re: HP Changes Posted, AFHS Changes for 2015
 

I give up on HP changes.

Try this^

Re: HP Changes Posted, AFHS Changes for 2015
 

Why wouldn't the 'mineshaft' conditions trigger, just simply be when there actually are mineshaft weather conditions, and not have anything to do with the top spot of the bottom half of the ladder, or what any car runs for that matter????

Like, anything less than 250' D/A is mineshaft ?? :confused:

Re: HP Changes Posted, AFHS Changes for 2015
 

Mineshaft conditions are something that we are not familiar with..... (out west)

Most tracks are not corrected, or corrected less than they should be. Phoenix is 1,060 ft and uncorrected, Las Vegas is 2,000 plus and corrected minimally. Fontana is not corrected and should be. The only track that could be considered "mine shaft" is Pomona.....and it is over 1,000 ft, but down hill. The difference between Fontana and Atco is probabably 3-4 tenths for our SuperStock car. I am not bitch--ng....everyone runs the same conditions. But....since I am retiring from racing....and going to sell our Dart...the question I get is "how fast have you gone"....well, we have gone 9.85 (unimpressive)....however, it would go 9.60 in the east coast.....la la la la

Re: HP Changes Posted, AFHS Changes for 2015
 

You don't think that would be? Would be in Div 4. Been over two years since I've seen anything like that.

Re: HP Changes Posted, AFHS Changes for 2015
 

The actual D/A to use could be argued, no doubt. I was just saying it seems to make more sense to pick a corrected altitude as the trigger rather than what the cars are running at an event. Like someone else said, Indy National event would always be 'mineshaft' conditions even when its a dog hot summer day.

Re: HP Changes Posted, AFHS Changes for 2015
 

Yep, that one might be. If the humidity isn't 90%.

Re: HP Changes Posted, AFHS Changes for 2015
 

Using a given density altitude may work, but all tracks are various physical elevations. Houston, Gainesville and Sonoma for example (and a few others I'm sure) are 100' above sea level (physical elevation) or less. Maple Grove is around 550' above, give or take. Vegas is 2,100 or so. Denver is over 5,000'. So the number would have to be changed. -250' below sea level at The Grove would really be -700-800' below track elevation, whereas the same air in G-ville would be -300 below track elevation. And Denver will never see air that good. Neither will Vegas, Chandler AZ or Brainerd MN (Brainerd and Chandler are 1,200' or so above). SO you kind of would have a floating number, specific to each track, as far as what would be considered 'mineshaft'. At least this way NHRA introduced, the number is the same, regardless of track and elevation.

Re: HP Changes Posted, AFHS Changes for 2015
 

D.A. in Denver is pretty normal around 8,000` plus. Mile High time it`s over 10,000`.
