OM617a flow rate ? - kmaser - 03-07-2013
I thought I could remember a discussion on the Om617a flow rate but could not find it. I want to check the flow rate against the R444-2 turbo map and see if I am overspeeding the turbo. Can anybody tell me the OM617a flow rate or point me in the direction of a calculator and the specs from the OM617a that I would need to determine it?
thanks

That's a cool page.
What you need to know is the Volumetric Efficiency of the engine or, even better, the volumetric efficiency curve. I bet it gets pretty bad past 3500 RPM.
