A dyno session would probably answer all the questions and is probably more reliable than a sticker in the engine bay!

Not really, unless you know precisely how much drivetrain loss there will be ?
Given the difference is such a small percentage, trying to determine this on a dyno run, means the difference will be lost between using a drivetrain loss percentage of 15% or 20%.
The sticker in the engine bay comes from the factory - also the options list for the car will carry the 822 code. It's not something that can be added on. A simple check on the options on the MB system will show 822 or not, easy check for confirmation of true 300bhp.

Two cars on the same dyno - one after the other - would make drivetrain loss irrelevant. Straight comparison of power at the wheels.
Car with supposed higher output ought to be showing a little more than a car thought to have the lower output.
Nope my cars dont have code 822... checked in the original service book.. both are 1988 cars.

Yes that's obvious... but not the point i thought was being made. I thought the point being made was to determine whether the 560 in question has 300bhp or 280bhp.

The Option ceased in April 1988 i believe.

^Agreed. Anyway as I said earlier ir seems to have Brabus Tempamatic. So probably a Brabus. And DRUK posted previously to say his friend owned it.

Maybe.... but when they go off topic in this nature, I think of it as constructive conversation.
I for one have learned something I didnt know before.
