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?

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

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

So its far from "recent" news

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.

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)

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

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.

      98 R34GTT 4k engine stumble

      By JC71 · Posted

      neither stumble or cut really seem to be an appropriate term....hard to explain its like a rev limiter but at 4k, but it violently shakes engine and entire vehicle as the rpms will not rise over 4k, even with slow acceleration. as soon as it hits 4k, it sounds like entire spark is lost entirely. plugs were 1.1 which I used as such, but later put in new plugs gapped down to .8 changed back after issue arose when I replaced the coils, still does it with either plug gap...damn and it was all running so good.

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      Oh how times have changed! I actually lean it out relative to my water/methanol injector duty cycle. The methanol adds a lot of fueling and you can then lean it out even more due to reduced knock.

      Yeah my thoughts are the same, a well thought out WMI setup, would be slightly ahead of just straight E85 and you're also chemically intercooling the charged air, dropping it even further. This is why you need to add so much more fuel as soon as you spray. I remember someone taking me through their set up before (Dennis, has a R33, lives around Cabramatta - no idea if he's still around on this forum). He would target AFR 10:1 on 98, then as WMI ramped on, AFR would lean back up to 11:1. Amazingly, he did this all through his PowerFC, a relay to cut power to his EBC solenoid if there was not enough line pressure on his WMI kit. And of course, if there wasn't any boost made above gate pressure, you wouldn't be accessing the load cells with heaps of timing for WMI. One downside to that rudimentary setup, once the WMI came on, the EBC would unleash the dragon, and of course all the timing. Tyres would fry lol.

      RB25DET with solid lifters - which cams ?

      By MBS206 · Posted

      Shimmed or shimless, still solid, no hydraulic pump up stuff.

      They have said food will be limited. Mainly meat pies and sausage rolls from memory. But they have a coffee van!
