how much faith in dynos do you have.

after to being dyno tuned I will probably never be on a dyno again. The only reason I like to see cobalt dyno #'s is product effectiveness and for the greater good of the cobalt community and its reputation.

I agree with you on dynos.
but if you think all tracks are equal then your deluding yourself.
You can "calculate" altitude/temp/humidity effects on your time....somewhat...
but what about track temp...tire temp....tire pressure....waterbox conditions....track timing equipment accuracy....startline track conditions....60ft traction....track rolling resistance...wind speed....wind direction....
there are just to many factors involved....exactly like a dyno....to have true accuracy.
The only way to have accuracy, is if all the variables are generally constant.
and the only way to do that is to compare on the SAME track...at the SAME time
similarly, the same dyno...on the same day....

cblt12 has the idea.
No matter which way you look at it, the dyno is still a piece of equpiment, and a track is still the real world. For being a controlled environment, a dyno should have less factor affecting it. And we all know htat regardless of factors at a track, it all boils down to one very very important factor -> driver skill.
Beyond that, I just find it sad that for a measuring device, a dyno has such a high error involved. Do you think that Omega would try to sell you a thermocouple or pressure transducer with the same error as a dyno? I think not.

I still view a dyno as a good tool. After my mods my baseline was 262. Then bcp tuned the car (leaned it out to 11.4 and bumped the timing up 2 degrees). I made 280 then and the car's power came on a lot smoother.
thats exactly what many of our points are. its a GREAT tuning tool, not a great power measurer (is that even a word haha)
