Reply to "How to increase the power handling of a ZF? (850 newton/meters or 627 foot/pounds)"

This was not mine zf , youst one from a friend. I bought a new ring and pinion for mine. At this time, we are closer to make more than 800 nm hapen in a zf.
We tried to call rtb and zf direct , we also bought a quife and we did a lot of basic groundwork with the zf now. I am happy to say : we are able to do it better now !
Friends from a big austrian aircraft company redesign ring and pinion to a modern "klingenberg" theeth with a bigger area and some other oil skills , so that the peassure between the teeth is not to high. All the new parts we develop now are at minimum factor 1.5 better than stock. We also do a new aluminium housing in cooperation with zf . Also the ratio is changed to about 4.0 , I think its a nice ratio for the engines with more power than stock.
And yes , this all is done by us. One had worked at zf and have done maybe more than 100 25-2 ,
So he know everything about the zf. Also he have better sinter plates for the diferential. The man who develop the new ring and pinion works for more than 20 years in the car and aircraftindusteoe and develops several gears for turbopropengines or mercedes.
I am happy to initiate this all, If somebody like a new ring and pinion please pm me.
