I am planning to take my car to Dyno. My car is NA right now and I want to see how much hp I have before I get my SC kit installed. Since I don't have any engine management, do you think one run would be better?? or should I do more. Is there a chance they can mess up the first run and i don't get accurate numbers?

 

In my experience, dynos are done in two ways. First, you go as an individual and rent the machine the by the hour. Or second, go as a group during a "dyno day" and get three runs for a fee of about $30 to $40.

In any case, there is certainly the possibility of getting a messed up run so I think three would be just fine for you.

 

Three is better, but I certainly wouldn't pay extra for multiple dyno's just to get a baseline of a basically stock car with no engine management.

 

Typically places that do dyno runs charge you for 3 pulls, unless you want tuning done. Then it's by the hour.
