I was just thumbing through some old photos and noticed my dyno numbers. I noticed it was the uncorrected numbers.

My chart has temperature, humidity, I know the altitute, etc.


My question is,

Is there a way to FIND what the corrected numbers will be? Some sort of an equation?

IMO, there isnt a huge point, the differences around here are minimal...5-10hp max.

I didn't know if it would even change that much, or how they figure out what the corrected numbers are.

195 whp sounds better than 185 lol.

lol, yea ive messed around with my charts in winpep or whatever the program verocious uses... and because we are so close to see level here, its a minor difference

If you have the numbers like humidity, altitude, etc. you can search for a SAE correction calculator and that will give you the factor. The factor is expressed as a %. Multiply your uncorrected number by the correction factor to determine the SAE number. Generally around here correction factors average .98 - 1.02 depending on conditions.

So, if you made 200whp uncorrected, you would take the correction factor and multiply it out, example:

200 * .98 = 196

or

200 * 1.02 = 204
