I've found out it's rather hard to exceed 400 IAS in Bf109E3, but sometimes you can do it.

Combat (full power settings - bold settings are your main goal):
- oil radiator almost closed 30% open (between 20-40% open, I'm modifying it all the time) - keep an eye on oil's temp all the time
- prop pitch anywhere around 90% (between 80-100%, I'm modifying it all the time, accordingly with oil rad modifications, and trying to keep the RPM in the desired area)
- throttle kept modified (accordingly with the above oil rad and prop pitch settings and trying to keep the RPM in the desired area)
- RPM around 2500 (between 2000 and 3000)
- speed over 400 IAS
- water rad fully open

Don't forget to lower/cut the the throttle in dives (and eventually ease your prop pitch too), and get it back once leveled.

Cruise (economy settings - bold settings are your main goal).
- water radiator fully opened
- oil radiator fully opened
- prop pitch 100% (between 90-100%)
- throttle around 45% (between 45-55%)
- RPM around 2000
- speed over 300 IAS
- manifold pressure as lower as you can manage it (to conserve fuel while keeping a reasonable speed)
