Here's a handy little bit of software I found. Put in your elevation, the current temperature, the barometric pressure and the relative humidity percentage. It will give you the correction factor for the numbers you get from your dyno.
It will also show you how little humidity effects horsepower. To make a long story short, at 70 degrees, 100 foot altitude and the barometric pressure at sea level, a change from 40% relative humidity to 80% relative humidity, the correction factor only changes .012. A change of 10 degrees in temperature would have almost double that effect on the correction factor.

If the data does not support the theory, get a new theory. (Al Nunley)
