Not many aussie dyno's give ft/lb @ the wheels unless you ask the operator spefically for it, what you usually see is newtons atw. Even if AU members were to give torque in ft/lb; you cant compare that with a US let alone FM rotor dyno, we have different correction factors.

Doesn't matter what rpm you are measuring it at, refer back to blackster's post.

No, what I said was re-read blackster's post, specifically the part on...

I have always been told that torque figures on chassis dynos are practically guess work which you would be better off ignoring. Note that I'm only referring to the number attached with it, the curve itself and the point at which said number is derived can be useful.

Therefore my previous statement of

is still completely relevant.

I know the original differences re dyno, units, temps, operators, etc.

You answered your own question. If by chance those variables mean nothing, have you thought that perhaps FM does 1:1 runs; meaning its done in 5th gear, therefore altering hp & torque?

There is a member on here that posted a formula converting newtons atw to Nm atw, from recollection the power run has to be done 1:1. So again, AU dyno dynamics and mainlain figures are not helpful, as they use 4th gear.

All in seriousness the only way your going to find similar torque figures, is if two different SE's with identical mods use the same dyno. Perhaps you should stop putting so much emphasis on dyno's, there just tuning tools; does your butt dyno feel a difference?

Heres mine.
But as stated before, the actual numbers vary from dyno to dyno and technician setup.
But the curve should give a reasonable representation.



I dont have a Torque print out

So it turns out after all that different dynos (whether caused by the operator, or conditions, or settings etc) give different results.

If only someone had mentioned that at the start we could have avoided all this bickering...

Between 320 and 370Nm atw depending on the switch position

Hrmmm., written sarcasm seems to be difficult to identify...

By doing so, we were able to quantify that Minx had 50% more torque at 3000 rpm than on my two runs (which were 8 months or so apart) hardly within normal tolerances of operator, conditions, etc. etc. etc. If you accept those kind of errors then good luck!

It seems that all that was shown was that your results one one dyno were different to the results on another dyno, and that there was nothing wrong with your car. Did the information supplied by Minx actually provide any of that information? no.

Not an SE, but retune on my NB, 176kw atw 12 psi, 365NM torque at 4500.

Managed 186kw atw on one run, but injector size not quite adequate, car didn't like it.
