Of course other drive train components need to be broken in as well. That's why I chose my words very carefully by only discussing the break in of the motor.

OK, thanks for the clarification. I think I mixed your post up with another post on this thread by a different person.

In that case, I'd say that it is mainly about the controlled setting and monitoring/measurement issue.

Also, did you actually follow up with the street engines to see how they were holding up with 100000+ miles? And if so, how large was that sample?
