Has nothing to do with boost or flow. Under load the turbo can get up to 1600 degrees. this put a bit of a load on the oil that lubricates that bearing. What you are trying to do is not have that oil burn and put deposits on the turbo shaft. When that happens the shaft gets "coked" up with burnt oil and eventually the seals will fail from this debris.
Most critical is after shutdown when the shaft sits there and heat soaks. The water cooling helps because the thermo-syphon effect will keep cooling the bearing even though there is no water pump running.
The higher heat resistance to burning of synthetic is a good thing to have on your side in a turbo.
You can put conventional oils in your car.......my Saab will have synthetic thank you.
