More accurate than what? The ONLY time an engine makes the power the dyno says it does is when you use observed numbers AND the weather at the track matches the weather like it was on the dyno OR when using corrected numbers the weather has to match.
It doesn’t matter which CF you use because IF you are going to live and die by corrected numbers any corrected number has to match weather conditions at the track.
You keep saying the higher the CF the more inaccurate it is. My question is by how much? 20%? 2%?
I don’t know but I’m doubting is more than 2% worse case scenario. If that.
Also, most flow bench software I’ve used corrects to STP.
Why not correct to 90 degrees, 80% humidity and a 29.0 barometer? You’ll see more days at the track with numbers like that than ANY CF I’ve seen.
I’d argue (and do) that the CF is not the reason why dyno numbers are all over the place. It’s shitty dyno operators that have sloppy methods or they are just outright lying crooks.
