Re: Index Change
Oh well (note sig change from AA/SA to A/SA), it effects everyone the same. Unless you can't run .3 under

Re: Index Change
The AHFS will impact very few combinations with the new indexs. The HP committees job just got alot easier.
The new Mustangs and Mopars will most likely never see an adjustment. The proper way to adjust horsepower ratings is to take the average under the index runs of each car/engine combination and average them against each other. Example: car/engine average for combination X = .95 under index car/engine average for combination Y = .75 under index The HP needs to be adjusted for up (raised) for combination X or lowered (decreased) for combination Y. They aren't reinventing the wheel or performing brain surgery here. Last edited by fredjohnston; 12-18-2009 at 03:31 PM. |

Re: Index Change
Or they could've just moved the trigger up .15, which is primarily what they've done. It just won't LOOK like a -1.55 under run on paper next time.
 Now guys can race to 1,150'. Maybe they can put a cone out there for that. Congratulations, NHRA, you've accomplished.... um.... something, I guess.

Re: Index Change
What about class winners do they still need to run -.50 under to win class?

Re: Index Change
I'm just curious, what happens to all the records now ? Do they change, or do they just start from scratch, or will there be all new records ?
I guess this was to even things out , but it seems to me like the sand baggers will be even farther ahead now. like if you run all out and your a sec. under , you'll be .7 under now , but if you were holding some at a sec. under , now you can run it hard and still be ahead of the game.

Re: Index Change
NHRA could have approached the indexes a different way. They could've just made a valve spring pressure rule that would slow everyone up. Make it so that the pressure can't exceed 150 lbs on the seat. But NHRA doesn't want to work for their membership money which means testing pressures of the valve springs.
