Im purchasing a pair of s/h standard GTR turbos for a biturbo project on another car, but what I wan't to know is WHAT is the reason for the ceramic wheels packing up on the GTR at just over 'a bar'..?
Is it the total turbine RPM, based on the fact that you lot are holding a bar into very high engine RPMs, so the turbo has to overspeed or run at high rpms to sustain airflow...?
Is the turbine inlet pressure too high, is it shearing it off the shaft?
Is it EGT related, on this engine, at these revs, at this boost level...?
Which part of the wheel is breaking, the vanes or the core..?
So basically, what I want to know, it is 'a bar' that is killing them, or something else, so in theory, in a different application, they could be run at more boost..
Thanks in advance..
