On the DB one should not go over the limit else the engine was considered
as dead or at least good for a complete overhaul, 2850rpm on the 605A was
the absolute limit until very late in the war when technical enhancement
permitted overreving above 2850 for short period of time.
It was possible to overrev the engine when switching in manual mode, it was
one of the reason why it was not recommended to use it over the automatic
one. Manual mode should be used only for ferry flight at low speed in order
to preserve fuel.
