CONTEST : Guess the HP and WIN!

Reading that, are you saying the dyno is in a temperature controlled room? Because the weather correction factor is based on the weather, not a fixed percentage. Unless of course the dyno is in a controlled room.

A 5% correction factor doesn’t make any sense outside of that (that I can think of).
It’s the correction standard as determined by the SAE (society of automotive engineers) and used by most dyno operators that want results that are inline with baseline standards. I didn’t add that info to confuse anyone. I added it because if I didn’t, then some would think I went for higher numbers by not using correction.

It’s ok to not understand it as I don’t fully understand it either. I just know that it is the industry standard used by most operators that want a more realistic number versus an inflated one.
