Most vary somewhat in what they will actually flow.
For instance these engines run stipidly high oil pressure on idle with most manufacturers using less than half a bar due to no load on static idle.
You have to work out the maximum and the minimum flow rate both at peak pressure i.e7 bar and at what rpm.
Also it must also filter at 0.8 bar or whatever your base value is when the engines hot.
Small particles are not harmful for the turbo,but may cause blockage of the restrictor.
If theres any bigger particles then the turbo will be the least of your worries.
Personally i dont know anyone who runs these for the above facts.
