Default See the post below. The question you are asking is as not as cut and dry as you would think.
What is reliable and in what condition? The question is fairly complex.

Default Our question is not what "race" MAX is, it's what did he as the engine
designer for a production based motor(RS4) think the max was on stock RS4 internals. I understand that designing for a race car is different. The point is that I'm sure in the course of his work on the production car, they did have a upper limit for the stock internals(RS4).

I've heard 550(crank) is about all they thought it could take or all they would risk taking it to. Obviously the production car was not at that limit.
