As lots of people are aware, the biggest weak point of the S63 is the connecting rod. For standard power levels they are fine, and run well within the failure limit. They are forged and are perfectly suitable for the job.
The issue comes when the power is increased beyond the running limit. Anything over that point and they bend, with varying degrees of damage caused. From a simple misfire, to a hole in the engine.
Broadly speaking, the aim for most engine parts is to run at around 80% of the failure point. Once you reach 100% or more failure is likely to occur. Aftermarket rod bolts are a good example as they are usually torqued or stretched, to approx 80% yield of the bolt. Some engine parts have limits well above the application, stock or tuned.
