I started looking and found this link from the wikipedia DB601 entry: http://www.scribd.com/doc/71362812/1...r-DB-601-A-u-B

Can any of our german speaking friends lese through this bitte and then reporten zu backen hier was ist gesayin ist?

Very nice find, however this is a manual from 1940 so there is nothing about the MW50 or any other boost system in there.

This is not the same engine that was fitted with the MW50 later. This is the DB-601, the later engine that used the MW50 was the DB-605. This is the engine used for instance on the Bf-109E.

It says about this engine that you should not run the motor in low rpm before the start on the ground for very long (or not at all if possible).

For this engine rpm should never (ever) go higher than 2400.
In a dive rpm should be 2400 but rpm of 2500 are O.K. for 30 seconds or less.

Ladedruckerhöhung (WEP) Power of 1.4 ata at 2400 rpm should not be used for longer than 1min.
Full Power of 1.3 ata at 2400 rpm should not be used for longer than 5min.
Increased Power of 1.23 ata at 2300 rpm should not be used for longer than 30min.
Power of 1.15 ata at 2200 rpm or lower can be used indefinitely.
