Dynodynamics Vs Mainline Dynolog

[Just Boost It]

it seems like dynodynamics on shootoutmode is the popular choice for a dyno readout but ive heard recently that autosalon changed their dyno to a mainline dyno . which one is more accurate?

[R31Nismoid]

they are a tuning tool

they are both accurate unless everyone gets on the same dyno on the same day, then you can compare.

otherwise. just a tool

two different dyno's (mainline and dyno dynamics) in the same city (around 5 klms apart), two days apart with similar barometric conditions. read within less than 1% of each other. With the same vehicle.

Not bad eh!....pretty acurate

autosalon

and yeah, just on that... the Cabin group have been using mainline dynos since 2002/3.

So its far from "recent" news

Ash...its [cabin] not Cabin

[R31Nismoid]

ok... :owned:

nah... i got one for ya

:lol:

Where?..which dynos? Anytime I have seen the same car go on a dynolog and then a dynamics, the dynamics always reads about 10-15% higher.

hehehe i stand corrected

Croydons...then Autosalon....and it was Stacey's car...so i should know.

I didn't say you didn't...but I think Cabin must have a 'special' version of the Dynolog software.

I know of a wrx that made 20% more power on CRD's dyno in the afternoon than it made on a Dynolog in the morning. There were no changes in between. Had the same tank of juice and all.

All the other dynologs I've seen read very similarly (comparing the same cars on different days)

[R31Nismoid]

did you record the temps on that day?

you said morning and arvo... so my bet there could have been a reasonable temp difference.

end of the day, does it really matter? anyone can can get any figure if you need too

Yep...it was slightly warmer in Syd than the gong...only a degree or 2.

Yep..I agree

This is from Mainline website, read it and it should hopefully shead some light on things.

Allot of the differences can be put down to the operator.

Well how does this grab ya...Carlos from Millenium Motorsports ran 599kw at Queensland 2 days before Autosalon on his Mainline dyno...and at the same boost levels ran 601kw on Autosalon's dyno.....he must have the "special" software too!

Mainline dyno's even run the same no matter if its 2WD or 4WD...we proved it in front of hundreds of people at Final Battle...there was 1kw difference between the runs.

I think what Mik is trying to say is Croydon's dyno is happy...if its so happy i should be rolling almost 520AWKW......i think im gonna have a word to Jim about my deflated power figures.

I Have seen IDENTICAL results on two different dynologs equate to 40awkw more on two different dynodynamics dynos in an unchanged trim/tune. Just my experience.

highly experienced acredited operators should not have such a discrepancy...as essentially the dyno's use similar hardware.

Haltech E11v2 with lambda + full logging at the strip is the best dyno after initial tune imo

[yogi000]

but i made 6 gazillion jigawatts of power too!
