To be fair, I did say dyno's could be calibrated and that corrections for relative air density could also be made. I'm also aware of the different dyno types, brake dyno's are more commonly used for mapping cars/bikes, inertia dyno's are the most common dyno used for kart engines.
My real point was that there main value, as an engine development tool, is using the same dyno and exsperimenti g with the different engine variables. Carb selection, jetting, swapping of parts, barrel and head gasket thickness etc.
But because of this, each engine builder has little motivation in trying to match his dyno, against a standard or anyone else's dyno.
When they do want to see how their engines compare to a competitors, they'll just get a third party (or one of their drivers) to buy an engine, run it on their dyno, then strip it down and figure what's been done to it.
Yes in an ideal world, you could ask for the seller of an engine for a copy of the power curve and peak figure and compare it against other engines that might be for sale, irrespective of who built them and know you were comparing, like for like figures...truth is that's not going to happen!
