Index Change

[Jeff Teuton]

Mike, I think it has been that way. Wasn't that the big deal with Sorenson last year when he dumped the water or something? It's the same as running 1.55 under in 2009. And when the semi-annual adjustments, the new average will be .15 faster than last years 1.00 under average, but with the.3 drop, the effect is a 1.15 under in 2009 average sorta like the 396 guys are commenting about.

Ah Ray, as of this time the records are still there.

Jeff, the flap with Sorenson was he ran -1.40+ the sea level index at an altitude factored track, then they say he didn't, and pulled the water trick. Jim

Hi Jeff. Yes, I remember the Sorenson deal. A car had to run -1.40 (back then, -1.25 now) under it's sea level Index. Meaning Joe in B/SA, if he ran 10.149 or quicker, he got HP regardless of elevation. Difference was, 10.149 is -1.401 under sea level, yet something like -1.77 under the Boise Index.

1 633 B/SA Hal Sorensen, Vancouver WA, '69 Camaro 10.159 11.93 -1.771

The statement in the new AHFS article states:
"Runs of 1.250 or more under the index will be reviewed and adjusted Tuesday following the event. Runs at National Events, Divisional Events, and National Open Events, including those at altitude factored race tracks, are included in the 1.250-second-or-more-under analysis. This is done to better react to any out-of-line indexes or under-horsepowered combinations. Therefore, at all such events, a 3.25 percent horsepower adjustment or index reduction will be initiated Tuesday following the event. The decision to adjust horsepower or to reduce the index will be at the discretion of the NHRA Tech Department".

So is that -1.250 under the sea level Index, or the particular altitude adjusted Index at that event?

You're right, Jim,

I looked in the wrong menu. Thanks for clarifying.

this did nothing but penalize the part time racer trying to go out and compete, factor the fast combo's as needed, this is a crock

well.....the index was 30 plus years old, change is good

[Rich Wallin]

change the factoring process, not the index

[Alan Roehrich]

Not only are the track "factors" suspect, but the system is flawed.

You call racing at altitude "having your cake, and eating it too". But when you get a combination HP running off of a bogus factor, you're "having your cake and eating someone else's too".

If NHRA is not going to correct the factors to the actual current local conditions, then they need to do just what they've been doing, only hitting cars with HP if they actually go 1.25 under the sea level index.

Again, if the track is factored to over 3000', but local conditions actually correct to 1000', that's like having better than -1000' under sea level at some place like Atco or Mission. A car running 1.25 or more under the factored index at the factored track probably wouldn't go more than 1.00 under at a non factored track in really good air.

Running ss/cm index @ ss/em weight....great!,thanks!...

[Mike Carr]

Thanks Mr Geary (I don't like calling anyone Dick, unless they deserve it. LOL).

Alan, I would agree with all of what you wrote. Wonder if NHRA would?
