Yeah I saw immediatly that it was for a G (the diff being with the laminar flow absorbing device). Thx for re-posting AoAce.
No prob!

Oh I understand that, have for years

What I don't understand is how guys like David can come here and make baseless claims.. Such that he had no idea how much the speed should be affected.. but did that stop him from making the claim? Nope! Now that we have some numbers to get a feel for the affect.. I get a good laugh at David's expence that he 'thinks' he can detect an 11kph difference that he didnt even know as 11kph until I provided him the data.

you still dont know that its 50kph difference and not 11...man im getting tired arguing with you...

and even if it was only a difference of 11kph, why shouldnt one be able to detect it???

You know what is even funnier?

In your last few posts you act as if you know what those numbers on the graph are.. Even though your first post you admited like me that they were hard to belive

Yet you came up with some 50kph number out of thin air

When it is actully only around 11kph, based on the numbers you want to use

Now who needs glasses? LOL!

David198502 10-31-2011 06:42 PM
well at first i only took a short glance at it.then i had a closer look after you came up with your 11kph...
those 11kph you see is actually the difference between the DB601 and the DB605 engine...
now who needs glasses?lol(never thought i would ever use this abbreviation)

C'mon guys there was enough blood wasted at the time those events took place. No need for anymore shredding here ;)

I think we are talking about two different things.. I am saying the difference in the two graphs is a constant ~11kph

You can, but not with the naked eye! You would have to log the data, so you can take into account the variations of flight, because the fact of the mater is the speed vary as you fly due to you making small altitude changes.. That is to say YOU ARE NOT CAPABLE OF MAINTAIN A PERFECT ALTITUDE !!! But don't feel bad most cant! Thus the variations in speed due to altitude changes are on the order of 30-40kph. So, the 11kph falls within that range, thus you can not desern which is which unless you also plot altitude

Ah.. ok, your right! I don't read German very well but that does make more sence now!

yes but these constant 11kph is the DIFFERENCE BETWEEN THE DB601 and DB605 engine!

Now I would like to know if someone has made tests:
Full throttle, optimal rpm

what are the durations before ruining the engines depending on rad setting.

100% open, 95%, 90% ...
