Weakest link in the power train?
Many of us are running engine mods that are producing HP and Torque values way above the stock numbers. I don’t see much about tranny mods other than TCU tunes and I know some people are running quaifes, but it seems most power trains are stock except for the engine. So what is the weakest link in the power train and what power level becomes unsafe for the tranny, drive shaft or diff?
I was once at a track that runs 99% American iron (Muncie, IN). According to a friend of mine watching, when I lined up with my SL55, the announcer says “gee I wonder if MB roadside service will come out when this Benz is broke on our track.” Apparently this got a laugh from the large crowd watching. I ripped off a high 11 and at least got some respect, but have been paranoid about breaking something ever since. Hence my question above.
The W211 AMG guys seem to be the most ardent modders so I decided to post here. I have learned a ton about my 55 from you guys.

Nothing major to report, but bout the only problem you face is twisting half shafts in the rear or even a tiny bit more common.....shearing suspension bolts out causing entire rear to collapse. Most of the time, people have twisted a shaft out from not running LSD.
Just satanic kinda torque and pressure being applied to that rear and the Benz ECU really fights wheel spin with brakes being applied etc.
I consider the E55 one of the greatest drag racing 4 doors of all time, but those half shafts would just shock you in the rear at how tiny they are, yet still handle the mountain of torque it takes to launch a 2 ton boat off the line.
ALL that being said, twisting half shafts is really rare but we have had just a couple of suspension bolts shearing over the years.
Over time tranny will eventually wear out faster. Just put in my replacement after years of hard service. They just over engineered the crap out of this car. The tranny is just a monster, the engine is simple and stout and the rear does the best it can to handle it all.
As far as the "benz will break on the track" comment. He's on crack, E55
s have probably run thousands of runs with very few problems.
Like this was gonna happen when you launched ya know?

The track at Muncie just doesn't see much other than American cars, maybe the occasional ricer. That's why I need to get some Indy boys to run out there with me and represent.
