BMW E90 320D 177HP Turbocharger Limit?

Postby nyxiz » Thu Apr 23, 2020 6:16 pm

Hi,

i want to know how much pressure/rpm my turbocharger is able to handle without damage.

First of all i have found a map named "charakteristisches Verdichterkennfeld" with label id: ASMod_nTrbChRed_MAP


and the second map is "Wirkungsgrad-Kennfeld in Abhängigkeit vom Druckverhältnis über dem Verdichter" with label id: ASMod_etaCmpr_MAP

Is it possible to calculate the max rpm of turbine which is "allowed" with those maps? If not, how can i calculate it?


In attachment you can find pictures of the maps above.


Would be very great if someone could help me out.


Best Regards
