Personally, I pretty much consider dynoing on the same dyno and under similar weather conditions great for baselining and doing mods, but thats where it ends.
You could put your bike to 3 different dynos on the same day and have an 8-10 hp variance either way.
With that being said, if you take into account a vehicles hp reading on a given dyno as being from a "happy" dyno, and down the numbers from there, and they are still big hp or torque, you are probably looking at a very stout motor.
Case in point here on the site would be BigSaints truck. 450 hp, lets say it was a happy dyno, he was really making 420 hp. Those are still very big hp numbers, happy dyno or sad.
What I would like to see is 12's with varying mods dynoed on the same machine one right after another.
Check out this article, its pretty good.
