How Much Does Density Altitude Affect ET

How do you measure the percent of oxygen?

Thanks

There are many different combinations of Temperature, Relative Humidity, and Barometric Pressure that will give you the same Density Altitude, say 2500 feet. The car should perform similarly in any of those combinations that equate to a DA of 2500 feet, but it can vary depending on the exact makeup of those measures.

I'm pretty sure your weather monitor needs to have an oxygen sensor if you want that info.

At first I thought there was a conflict in this statement. However are you saying at the same DA the car will perform similarly but not exactly the same depending on the differences in the factors that determine DA?

Yes, it sounds like you understand what I was saying.
