2011 ahfs

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:


Under Index
Horsepower Increase
Index Change

1.000-1.099
1.25%
-.05

......so what does -.85 to -.99 get?

[Jeff Lee]

I don't get the index adjustment. The index covers all vehicle combinations (in the example K/SA) so why would it drop .05 or more?
Sorry, not understanding how that is possible...

[Ed Wright]

Jeff, that's the SS "hood scoop" cars, right?

Amazingly, I have had very little input on this subject from any fellow div 6 racers. I do think the proposed changes are a step in the right direction, please let me know what you think.
One additional suggestion I had made is to post the qualifying speed. I am not suggesting those lifting at 1000' should be penalised, just suggesting it would help level the playing field for those us who don't have a crew member to stand at the 1000' mark during qualifying.

Yes, as Ed said, the index change is only for classes that use the pounds per cubic inch factor like SS modified.

Us AMC'ers aren't always the smartest bunch but this just goes to show everybody Ed's smarter than I

Jeff thanks for the pics I have been busy sorry I didnt reply to your e-mail..

As I look into my crystal ball, I can see the future.....

It's Boise or Tucson with a sea level weather condition like we had a few years ago and guess what......

10 or 20 combos get HP on Tuesday and have to live with it when you are in Div 3 or 4 at sea level in August with a 28.50 baro.......

You wanted AHFS at the altitude tracks and now you have to live with the results...

I notice there is nothing in that draft to address the weather conditions. If NHRA does nothing to address the problem of weather conditions skewing the AHFS, the AHFS will remain broken, and the racers will continue to be screwed by it.

It's been said repeatedly for years, in order to work properly and fairly, the AHFS system MUST correct ALL data to an SAE standard sea level day. Each Division must have its own regularly calibrated weather station, to be used at the track before and after every session, or the data collected is skewed and worthless.

If the average racer can afford a weather station, then NHRA can afford to buy 7 nice ones for their staff, keep them correctly calibrated, and have someone on the starting line record a weather reading before and after each session.
