That wasnt the argument.

Yes, it was.

You said
>> You've just guesstimated a guesstimate.

And I explained to you exactly why a corrected figure is no guestimate and
you cut the rest because you dont like being wrong.

"Mr. Pot, Mr. Kettle would like a word with you"

Despite what you say, unless you have measured the power on a bench and
then in the chassis for that particular car, the 'corrected' figure is
pissing in the wind.


The corrected figure has nothing whatsoever to do with engine or chassis dynos and obviously both cannot be compared. Ans as I already stated you cannot give a flywheel figure on a chassis dyno anyway.

The "corrected figure" only relates to the absolute atmospheric pressure and temperature and both are corrected to a standard pressure of 1019mb and 20 degrees c. I t has nothing whatsoever to do with chassis or engine dynamometer comparisons.

A chassis dyno is just as accurate and measures as ir says rear wheel Hp CORRECTED to a standard pressure and temperature if you want it to. Or not if you dont but thats useless.. This obviously includes all transmission and tyre losses as actually happens on the road.

An ENGINE dyno does exactly the same thing and it too is corrected in the same way. Unless you have a specific reason not to do so. In which case just like a chassis dyno you instruct it not to bother.

Correction factors have absolutely nothing to do with the difference between the two types of dyno or measuring "flywheel" or engine power on a chassis dyno (which is and will remain impossible)

Do you get it yet???




However, it wouldn't have been good for your business if this was
publicised.


Prey tell me why not?
What EXACTLY would you publicise??? This should be fun...
