each car will not dyno the same////it all depends on the dyno, the car, and the conditions. a dyno is meant IMHO for only one thing...a baseline.
Exactly. That was basically my point. My car could dyno 291 somewhere else for all I know, but it dyno'd @ 270 with .95 SAE corrections, if it was STANDARD it would have been @ 284whp
But baselines are only worth it if, after your mods, you continue to take it to the same shop and dyno the same way every time (ideally, with the same conditions). I'm surprise no one has ever sat down and wrote an "in stone" guide or set of rules of dynoing that the masses should follow to make number comparison worth it. I know one car isn't like the other, but in the same conditions, dynoed the same way from car to car, the difference shouldn't be more that +/-5% at baseline, I wouldn't think. Until that happens, it's almost useless to compre numbers other than those from the same car over and over. Dynos are, after all, experiments. If you think chemistry, your using the same ingredients with different methods to get different results. What can you really compare there other than do it this way you get a different number. You can pick and choose which ever number you like better, but in the end the ingredients are the same, so you haven't proven anything. So all in all to make dynoing usefull for others, especially when comparing a baseline to a bolt on part, not to pick and choose the method to get the number you want. Sometimes, easier said than done, tho, I know.
That's my 2 cents, not directed towards anyone, of course, certainly not towards the poster.
