Yes, but 930 develops it's top power at lowly 5500 RPM. As 930's don't have to be revved to high heavens just to get going, rod bolt problems are highly unusual.
Also, forces on rod bolt are proportional to square of RPM. Thus, bolt will be subject to roughly 25% more force at 6200 RPM than at 5500 RPM.
Of course, there will always be a doofus who revs his 930 to 7000 RPM beacuse it "redlines there", "is ment to be driven hard"etc.
