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?
