Correction Factor
A key element to producing comparable dyno charts on a global basis is the Correction Factor, SAE Standard J1349, which applies the following weather station data--atmospheric pressure 29.23, air temperature 77 degrees Fahrenheit and humidity 0 percent--to all tests. These exact figures allow apples-to-apples comparison of runs from different cars, different facilities, etc. So graphs with SAE-corrected power were made to this standard. The dyno in question must have a weather station and the proper software in order to generate SAE-corrected data.

Either way, if this is uncorrected... you need to get the corrected #'s man! You are way above sea level. I would love to see what the corrected #'s are... Or just go to sea level and do a dyno. You have such great #'s for how high up you are.

i think what everyone (including myself) is getting confused about is... atmospheric pressure. at sea level you make more power, thats the root of this discussion. and we are grouping atmo, with humidity. there is no atmopheric pressure here, and no humidity. well, you make low power here, and down in diego, the cars rip ass. i dont care much to argue about all this crap, bottom line is, thanks for the props that have been given. i stepped to what you guys asked, and if its not apparent im making more power than most, on a roller dyno, then that is up to the person interpreting. what if i stepped on a dynapak??? 250ish, you betcha. so take it where you will, ill still hand versionJDM/yellows2kpower/wisconsin/steveC/mustangkiller01,,, and all the other ap1's there asses if youd like to step into the ring. gears no gears i dont give 2 shits. my main goal is to win races, always has been, and ill do whatever it takes to make it happen.

Lower humidity is better. Water vapor contains oxygen, but it is unusable for a car engine. Trust me, I live in Florida.... Higher humidity kills your performance. Now, it is true that right before it rains, it usually gets really cool. So while the coolness = more oxygen/more performance.... the humidity = less usable oxygen/less performance.

oh yeah, one more thing. remember, dyno numbers dont mean anything if you cant duplicate that on the street. like supras, that dyno 975 wheel, and run a 12 second pass. not only are they lacking proper suspension setup, but more than likely short of a proper driver for such a car. i rape this car, and know how to make it go, that is to my cred, and until you see it in action, you wont understand what people like mike, and jimbo are talking about. just test me, at a light, i promise, you wont win. hehe. lates mayne
