Re: ahfs question
 

Mark,

I don't think it's an either/or situation applicable to all classes. NHRA was just stating that adjusting HP (for Stockers/Superstockers) --- OR --- Index (for Comp style cars and Hemis) would be at their descretion. In other words, the 1.25 under barrier may not be anchored in concrete.

Re: ahfs question
 

Jerry, I can't think of a past example where they have done anything other that the 1.40 hits or the AH index reduction because of the exclusivity of the combo.
Can you?

Re: ahfs question
 

Mark,

No, I can't. But since the inception of AHFS, NHRA has never intimated that changes could be made "at the discretion of the NHRA Tech Department". Now they have. Which might mean that a 1.25 under run at Boise in the Spring in mineshaft air may not get HP or Index. :)

Re: ahfs question
 

Yes I can.
They gave me 13 horsepower at once The car was rated at 152 they raised it to 165 (in one hit). And at the time, I never went fast at a national event.
Do the math how does 3.25% of 152 equal 13 . By my non fuzzy math it comes out to 8%.
Thats were there discretion comes in. You have to play by the rules, THEY DON"T

Re: ahfs question
 

Art, they multiplied the 3.25% times 2.5 atmospheres for the amount of boost you were running at the time, and it comes about to around 8%. As good a guess as any, huh?

Re: ahfs question
 

You guessed wrong.
You guys with this boost stuff should really read a bit before you post about the evils of boost. How much boost do any of you think I was running? Do you honestly think you can put unlimited boost into an engine? Remember this was a stocker You can't run huge water to air intercoolers. I couldn't run any intercooler at all. The only adjustment I had was fuel pressure. 95% of the stockers out there flow a lot more air then a stock head would flow. But if you add a few pounds of boost people think you have this huge advantage, and anybody could go just as fast.
The car I run now has no intercooler either. I have to ice the intake manifold to go fast
Just like everybody else.

Re: ahfs question
 

Art,

It was supposed to be a light-hearted way of explaining how NHRA got there. It just so happens that 3.25% times 2.5 comes out to 8.125%. Pretty close to the 8% you mentioned. Sorry!

Jerry

Re: ahfs question
 

I'm sorry Jerry. Didn't mean to jump on you.
It's just that the boost is a touchy subject with me. And whether I got hurt by the horsepower or not, they broke their own rules by doing it.

Re: ahfs question
 

Has anyone done a spreadsheet of this for the various tracks that could take the records list and autocalc it across ?

If its sounds like something that someone else would like to do/see but dosent know how, I know how to do the excel part I just need someone to check/verify a couple of the calcs as well as be 100% sure Im putting the right info into the sheet.

PM me if youd like it, personally Id like a list of all the records and what has to be run where to beat them on alt factors.....I like it all laid out in front of me....

Cheers

Re: ahfs question
 

Anybody known the answer? Altitude tracks at national and division events, 1.25 under altitude index or 1.25 under sea level index ? AHFS Can somebody ask at the Winternational`s? Tried to call Bruce no answer. Tom
