I asked this question of a well known BMW race shop and parts supplier, who told me that they had 2 cases of spun crank hubs on their cars.
That said, the jigs for drilling straight holes in a crank had better be pretty good. I will be planning this as well as upgrading the wheel hubs in my track-toy M2. Ray |

That is why I personally prefer the gintani design.

After many (many) hours contemplating all of the CH designs, Gintani and Precision Dynamics were the ones I was most confident in. Both of these employ the same philosophy, however the drilling approach is different. As I said the Gintani is drilled 90 degrees from the crank. Both of these have all of the geometry machined and would need a very large piece if steel to fail in order to spin.
I am happy I did it, it alleviated that slight anxiety I felt. Very similar to how I felt about my E92 M3 rod bearings.

How much hp is an upgraded one piece crankhub like the gintani one good for? When would a fullly built engine be needed? If venturing past 700? 800?
Crankhub cost - About $4-5k? Built motor cost - Does anyone know? $8-12k?

A built motor would likely be much more.
