Vegas SS Qualifying - WOW!

Stewart Way · 11-02-2007, 12:18 AM

Comparing the top 18 SS cars at Vegas that also were also at Pomona looks like around an average .16 quicker against the factor in Vegas than at Pomona. All 18 were at least .07 quicker. Don't think that is all starting line and humidity. Think part of it is the wrong factor. All runs should count.

Remember, Vegas was a class race. Dan went 9.50 in Vegas with the heads up tune up and 9.46 at Pomona in race day mode. Same with several others I know of. Most SS'ers hold about .15 for heads up, which makes the factor about right.
That being said, for years I've advocated correcting all runs to a constant norm from track conditions for records and AHFS review as dynos do - say to 29.92 bar, 70 degrees and 20% humidy. We all do a version on it to dial our cars so let's have NHRA do it for those reasons. -600 feet at Houston and Atco corrected up, 11000 feet at Denver corrected down, etc.
A simple computer program to implement, could even print the DA on the time slip.
Too simple?

Good post Stewart. I think the factor is off too.

One thing I don't understand is that everyone is saying that all runs should count...I'm glad the factored runs aren't! I wouldn't want my combo to get HP from an unrealistic run at a factored track. If the car can't run the number at sea level, then it shouldn't count for AHFS...the fact they can set a record like this is bad enough, don't make it worse!!
