Watch this video......

Also, PEC-ATL does this multiple times a day to the same cars. No issues.
I wouldn't do it though......Why would you do it more than once anyway?

Almost makes me want a PDK...nah, if I cannot do it myself forget it. But that sure is impressive and it looks like fun!

At PSDS, the same car does roughly 100 launches in a single day. They stay for about a year in Alabama (I'll never purchase one of those). At least that shows their confidence on their equipment. Those cars are also severely abused in the track. So, unless there's some ultimate hooligan using the launch control nonstop, it shouldn't be an issue. Quite different from other brands...
Of note, the PDK is a closed piece of equipment, in that there's no clutch replacement for the life of the car, so I've heard. Gotta replace the whole thing.
I don't doubt the PIWIS has a counter available. German engineering borders OCD. IMHO, there's other ways to abuse a car more severely (high revving with cold engine or constant short drives comes to mind).

It seems the secret of PDK durability is in the strength of the assembly, and the liquid cooled clutches, and the ability to very quickly control the clutch slippage by just the right amount of tire/road slippage, such that the clutches do not wear during launches - because the slippage time is so short along with lack of heating during the launch. It's a beautiful thing.
But i am still shy about launching mine. It has zero launches on it. Maybe I'll get brave sometime and try it. 44 months of new car warranty left. But still I'm reluctant...

I launch mine fairly regularly (it’s not as savage as you would think on the components....not like just dumping the clutch....way more complexity to it). It’s a blast when I get a new passenger and a pile of fun to just floor it and hang on.
I have no no worries about durability as per the video and from friends with 911s. It’s a Porsche and meant (engineered) to be driven hard.....not like the Italians or British manufactures.
Worry less, drive more = more smiles per mile.

This article on the 50 launch test quotes Wolfgang Hatz as saying "There is no limit" "when someone asked him how many violent, Bugatti-quick launches the 911 Turbo S can perform before grenading itself."

Thanks for the video and article. Impressive durability! The no-hands launches didn’t seem that smart but it was notable how true the car tracked with all that power going down. Now to find somewhere to give it a try.

Whenever I think about launch control, it's usually because I'm driving in traffic and just wish I could leave everyone behind and have the road to myself.
Whenever I have the road to myself (somewhere that would be a great place to try launch control), I'm already enjoying myself and completely forget that launch control is even a thing.
I'm still at zero launches.

Well, keep in mind that no-hands launching with AWD is likely a bit less risky than no-hands launching a RWD 991! The balance of power between front and rear during hard accelerations like launch is near-perfect and adjusts instantly to grip issues. I don't think I would launch my RWD GTS without a firm grip on the wheel.....
