2 things most aussies don't realise:

1 aust is the clear world leader in aftermarket dyno technology and almost the leaders overall oem/f1 etc type dynos

2 aust are also clear world leaders in aftermarket ecu's by far

Thank you for the opportunity to ask stupid questions!

Ive got one for you:

The guy who is currently tuning my XC, has a "old school" dyno, its not even digital, it has x2, x4 etc switches, and 2 big dials (one for roller speed in KPH, and the other for torque/power reading, depending on what position the switch is at) my question is: There are many rumours floating about that this particualr dyno is 100% accurate up to 200rwhp, but after your car exceeds 200rwhp it tends to be very generous? Is this possible?

Nick> It seems there are actually three things most Aussies don't realise - the third being that a dyno operator doesn't have to know jacksh!t about how a dyno really works in order to use one ...

Sorry to be a bit harsh on you BUT you have left yourself wide open on this one and, going on what you have posted thus far, I think you really need to follow thebrunks' advice on this before you set yourself up as an expert on the physics of dynos.

MS700> It sounds to me like your friend is using a "brake" dynamometer as opposed to the type Nick is referring to here which is an "inertia" type.

profrat> You have posed some really good questions. To answer them all completely would be quite a volume ... you will find a search of Google (as has been suggested) will yield you a heap of info and save a lot of duplication of info on this server space ...

yes its posible as early units used current draw to sense load not always but comon and all it takes is resistance etc to varie readings etc!

ummmm when have I mentioned inersia dyno's?

inersia dynos are purely ramp test dyno's that are not load adjustable during tests and to the best of my knoledge no aust manufacturer wastes their time with them? hmmm

the old turd on the rollcage trik following the yanks dont always get you there first?

turbo6man pls dont take offence as none intended and to answer all questions thus far to the letter would take forever but searches like that should really be compared to the rest and although I have not searched for a long time there were hunderes of thousands of results read on if you like as you will find that many variations its not funny.

have you ever made an inersia dyno?

the instructions are there!

I have! and repaired them and owned multiples do we see a trend here?

mate pls and I mean pls think about what I have said as I do have a little experiance there under my belt I maybe sucker no1 but my knowledge is beyond most of your (the readers here) comprehension!!!

I still regard you as a friend so ask as many q's as you like and even answer with your knowledge as I may learn too but pls dont under estimate my knowledge!
