DYNO Comparisons....they have a low reading dyno

[Batlground]

its more accurate because its not an inertial dyno. Conditions are easy to duplicate run to run.

Dynojets meaure rate of acceleration, not load so the dyno dynamics and dynapacs tend to read dfifferently.

That doesn't make it accurate it makes it repeatable. I'm not saying its not a fine dyno...

I think we are saying the same thing, i was resopnding to Spoolin.

Most people prefer the steady state method of tuning because it allows you to more accurately tune the car. YOu can tune individual cells, different areas of the map, etc. With a load bearing dyno you can accurately find peak cylinder pressure without guessing.

Dynojets are not know for being able to do that. Since they are inertial dynos there is no load, and its not really possible to do "true" drivability and you never really know if you have found peak cylinder pressure or not. I mean you can find the same means to an end, but its alot more guessing involved with the dynojet.

Problem is that a good Dyno Dynamics or load bearing dyno is $100,000+

Hence why most shops have dynojets, they are cheaper and when used by a seasoned veteran ALMOST the same results can be found.

As far as ACCURACY, its in the eye of the beholder. A dyno is a measuring stick. Its Accuracy cant be compared to other dynoes. It can only be compared to itself. You cant say that XXXs dyno makes this whp and YYYs dyno makes this whp and its not accurate.

I agree with the original statement that most of the dynos in the metro ATL area are prob within 1-5% of each other on any given day.
