ahfs question

In this statement it says any run of 1.25 is automatic even at altitude tracks.

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

Does this mean 1.25 under the altitude index or 1.25 under the sea level index?

I have a sneaking suspicion they mean the altitude factored index. Guess we will not know until they clarify the rule or the first race it happens. Jim

I hope you are right Jim. But I woulkd still like to go to a density altitude format. To really make it equal.

It should count for AHFS at alt. tracks based on alt. index. The factor is good enough for records, it should be good enough for HP. Competition Eliminator can get their indexes hit at altitude tracks based on alt. indexes, S/SS should also.

I agree 100%.
Besides everyone knows that a big block isn't affected nearly as much as the small block at altitude. Right?

Ty the comp cars don't get hit during qualifying.
