Dynos - Shootout mode vs Non Shootout mode

[B-Man]

Hey Folks,

What's the difference between shootout mode and non-shootout mode ????

Thanks,

[meggala]

shoot out mode is more generous but if every one used shoot out mode it would be a good guide as you can play with other settings to lower or raise the power.

thats why I dont trust most dyno figures unless it come from a dyno alot of people use

Damn, I just wrote this whole thing out in another thread in the performance section.

Anyway, I'll post it again, so if it's wrong I can get flamed twice

Shootout mode is meant to be used to compare figures between cars. It locks the roller ramp rate, and it can't be modified at all, so you can be sure that any car measured with it can have its power accurately compared with any other one tested with it.

Now, from what I've heard, it adds around 10% to what you would normally get on a properly set up dyno, so 203kw really is around 184kw (A damn good result considering you've got a stock ECU, benm). That said, you can't really just take off the 10% extra to compare with people run in non-shootout mode, as this opens you up to differences in how the non-shootout mode dyno was set up.

So, if you want to compare figures use shootout mode, but be aware that the figures are inflated.

Cheers,

Michael

So when I view my dynosheet and it has printed....

"Atmospheric Correction = YES"

Does this mean that it was run in Shootout mode or does it mean something else????

I'm not sure if it's the same as the DynoJet ones in the US, but they can compensate for altitude. It might be something like that. It may have some sort of temperature compensation.

Even when the Dyno dynamics dyno's are run in Shootout Mode, they can AND SHOULD compensate for atmospheric pressure, temperature, humidity etc.

If anyone noticed, at the Unigroup SAU dyno day they were inputting these variables into the software before every run. This is especially important in comparing different cars in shootout mode as a temperature/pressure/humidity change could significantly alter the performance of a particular car.

Hope this helps.
