Sorry for my probably stupid question, but what are the benefits of a polished crankshaft?

Huib: Yours is not a stupid question at all. This type of work is very common in the high-performance racing engine industry. This type of processing is performed to improve performance and extend life. WIKIPEDIA gives the short list of the advantages: Advantages of superfinishing include: increasing part life, decreasing wear, closer tolerances, higher load bearing surfaces, better sealing capabilities, and elimination of the break in period.[1] A colleague of mine, Jack Clark, used this method on race engines on Formula One like cars to extend their life from several races to an entire season. This effect can be easily created with centrifugal isotropic finishing.
