sae is the only way that I run my dyno. I had a ricer tuner come in and rent my dyno for a few hours last week and he changed it to std and pissed me off. Of course his numbers were up about 20 from what they are sae so I guess that is what you do if you have a Neon.....

Someone mentioned if we correct dyno numbers why not correct track numbers. Certainly makes sense here, why should you correct dyno numbers when you live in Denver where the air is thin and you don't make the power like the sea level states? I only know of a few people who use correct track numbers but honestly thats the only way you can get everything to line up.
For example A denver guy dyno's 400rwhp corrected but only runs 13.5 @ his local track due to altitude. So is he right to say his car dynos 400rwhp or that his car goes 13.5s? I'm tired of the dyno BS around here, who cares if your car makes xxxrwhp sure its good on paper but it ONLY makes that power when you car sees @ 77 degrees and 29.2 inches of pressure.
So what happens when you go to the track and run a 12.5 because your @ 4000' and its 90 degrees outside? Do you correct it to match your "corrected" dyno numbers or do you keep telling people you have a corrected 400rwhp car that runs uncorrected 12.5s?

Yes, Phil it is an endless arguement. Dyno readings vs track times, corrected numbers vs uncorrected.
Same issues plague many sports from track & field to boxing divisions.
Racing/track times have many variables, from tire selection to the weight of the car.
The dyno is attempting to eliminate as many variables as possible. While the dyno reading may not be as important to the pure racer involved in competition, for the average enthusiast it may provide you with the only objective way to measure a performance gain.
Interestingly enough, the NHRA actually does has a correction factor for altitude, but that would probably not be a very practical solution.
I can understand your point. For the true racer, who cares about dyno readings. It's is who wins that counts. But for the average enthusiast, dyno readings carry a huge marketing advantage.
Everyone just wants them fair so you can make an educated decision.
