It can't be proven. Like a lot of similar topics its just a theory. There are thousands of crossdrilled cranks running well over 6000 rpm without failures. If the results don't agree with the theory, get another theory. That said, we use k1 in some builds. All parts have their proper place.
If you happen to visit the PRI show this year I highly recommend stoping by the Winberg Booth and chat with either Randy or Dennis and they can explain a little more in depth.

I had a week before a thrust bearing failure.
My evo is built with cosworth parts and cosworth bearings.
max rev 9800rpm.
I am wondering what was the problem that cause the failure....

Ive seen Cosworth bearings fail more often than Clevite or ACL, a much higher failure percentage. Im not exactly sure why that is, but it happens, and Im not the only one to notice it. I asked a couple big shops if they heard of anything similar and they saw the same problems.

I have used Cosworth bearings in over 50% of my engines and all have been perfect but then I pay more attention to oil flow also.
