Don't be daft.

It's a standardised figure.

You "think" do you? I have explained how they work to you the sadly baffled several times. You dont know your arse from your elbo and keep cuttin everything out. Keep digging yourself in...

OK then every dynamometer company and the likes of recardo developments and all the big car and bike manufacturers are wrong and you are right then.

Prey tell us how?

Oh you cant...

Yep basically the same baro corrections used for mapping an ECU or giving a starting aero setup.

'Corrected' = 'fudged to say whatever the punter wants to hear'

Ok, I've now heard two bits of this. So there are two sets of corrections : one based on environmental conditions, set according to known standards. And the other which is the fudge factor to convert from wheel BHP to engine BHP.

Now I think we all know the latter are the ones which are notorious for being over-egged. But Burgerman has carefully said he's not talking about those - so why do you keep ignoring what he says and pretending the second set are related to the first?

You misunderstand me.

I have very little faith in any figure that claims to be 'corrected' - as this almost always means it's being fudged to make it look more favourable to the target audience of the person producing said figure.

Maybe I'm just sick of marketing people quoting 'corrected' or 'seasonally adjusted' figures to me.....

Yeah but it's based on known quantities and is pretty simple. Probably GCSE physics FFS!

And anyway, it wont always make the figures look more favourable.

Yeah, I understand exactly what the theories are.

All I'm saying is that 'corrected' figures are almost always used to hide something / fiddle the figures to show what you want them to show.

I deal with 'corrected' figures all the time - but no matter how sound the theory is behind them, they'll always be a fiddle.

Yes.

And

No theres no such thing.

Cos hes simple and has put foot in mouth...

Oh, the irony.

Not at all you didnt even undertsand what a correction factor was or is.

No it means on any DYNO rint out that its corrected to whatever correction factor it is using which is also stated.

Eh?

Exactly. Working for a motor manufacturer, I regularly see our engines on the engine dynos. As an example, one of our engines is officially rated at a corrected 300bhp SAE, but I've never seen one on the bench that throws out less than 310bhp.

Despite never seeing the same figures twice on the bench, once the correction factor is applied it's always 300bhp +-1bhp.

Its not "theory" and works perfectly in practice.

Rubbish they correct to a standardised sea level standard pressure and temperature to make direct comparrison possible.

No they are not. And whats more if you think so then you simply look at the CF: 0.00234 or whatever and see at what pressure and temp it was during the run. I have never yet seen one thats more than 2 percent either way at the extremes so if it is then something is obviously suspect.

Or any other one of a multiple of operations. Apparently its all fudged and meant to inflate power figures! :)

Strange then that many graphs are corrected downwards as well...

Do you really think anyone reading this thinks anything but you are a fool?

Thanks for all the posts, but your ranting barely reached a 1/10.

Was nice of you to play, but it's all a bit pointless unless the respondent gets shouty and sweary.

I can't be arsed anymore.

Still, it filled a bit of 'downtime' whilst waiting for files to load from the network drive.

By which you mean you made yourself look clueless again? Have no reasoned argument? Dont really understand dynos or correctionj factors?

I already knew that from your first rude post.

Oh dear.

You've been nicely trolled on this one - I knew how touchy you are when anyone questions dyno outputs - as I say, nice of you to play, but you didn't get shouty enough to make it worth continuing.

HTH. HAND.

That's right Steve, you are the puppet master, playing people along with your masterful subtlety; you aren't really a touchy gobshite who suddenly found himself splashing around well outside his depth. We bow before your revealed genius. *bow* *bow*
