Is it still t-50 ?

Rene maybe we shouldn't go this way. Because then we have to know a lot more parameters, such as composition and homogeneity of the material, exact shape of the teeth to determine what amount of material is in constant contact etc...
I'd rather leave it to specialized TRD engineers...
...I think more about the results of their work which in the case of ZF are available in the user manual, and sometimes outright on the box.
I had hopes that TRD or Toyota also provide such data.

I need reestablish questions for You.
Are 10k rpm that You have entered an engine speed ?
And from where do You get this data, from your own experiences or maybe from some book ?
Im asking not to undermine them, Im just looking for sources with whom I could get familiar too.
