Dyno question.
My experience with dynos has been limited to engine dynos. In this case, the computer that runs the dyno also reads ambient weather conditions (temp, humidity, barometer) and generates HP/torque numbers that are actual and altitude adjusted. This allows you to dyno at anytime and have apples to apples information if you, for example, were having a carb built by a shop out of state.
I want to get the vette chassis dynoed and have never seen this done or really even seen the sheets you get. Do most places give corrected numbers or not?

Re: Dyno question. (LT-4 CE)
Thanks,
I've never gotten the visual graph before, just a table that lists the variables on the horizontal and rpm on the vertical. I supposed the graph would be easy to build from there, but it is not necessary.

Re: Dyno question. (LT-4 CE)
I think if the graphs as mojos says, "SAE corrected" then they are. When I just did mine Friday, the guy said they were NOT corrected values, hence the 30+ HP loss I showed. :rolleyes:
There are calculation on the net that you can correct to. Not sure how accurate they are.
Neither of my dynos I went to were corrected. That is why you should always do a baseline run to see what the caparison is off the bat with the old tune. That is not always that easy to do, expecially with a change in headers or other "equipment" upgrades.
And even during the runs, DA can change and skew the results.
That is why I probably won't be heading back to a dyno anytime soon. I personally think they are a waste of money. I dropped 200 dollars on Friday and really came out knowing exactly what I already did know. :rolleyes:
Kinda silly. LOL :smash:
