No doubt the GTR is a great car apart from its chocolate gearbox but the 911, what a machine. I'm sure there is a video where a journalist does something like 50 launches back to back in the Turbo S and it doesn't skip a beat.
It was nutter Bill Caswell doing it on behalf of Road & Track. 911 Turbo S. 50 consecutive launch control starts. No issues. It consistently hit 60 within a very tight margin of each run. https://www.youtube.com/watch?v=A5DRCTW-Q7oPorsche rates the PDK's clutches for either 2000 or 3000 launch control starts. I believe Nissan doesn't really ever want you doing more than 20 or 30 in a GT-R. 2 orders of magnitude difference. One of many reasons why the Porsche costs so much more money.
Also if I remember correctly GTR gearboxes have been modded to handle LC better. To put forward claims as to PDK's superiority you'd have to have a new GTR do the same as Porsche and break its box within those 50 runs. If you have a link to a test like that I'd like to take a look.

te on launch. I'm sure the software updates have improved it, but it'd have to be some fking code to up its game to the level of the tried and tested PDK. I'm sure it's not often an issue if you're not doing launches (who is), but we've all heard a few horror stories now. J4CKO said:

Sixty grand difference, if its performance in a straight line, spend ten on the GTR and see what happens.
Or get a 2nd hand 996/7 turbo and take it to 9e but that's not really relevant to the test in the video is it?Both are so quick its irrelevant, been in a 991 turbo and got out wondering what happened.
Like I said not relevant.

They're not really baseless claims - the GTRs gearbox was widely reported to be ste on launch.

The boxes on the GT-R are a known weak spot when it comes to Launch Control but how many times will you use it & with a 60K price difference there's enough left in the kitty to cover the cost, then again it would still be under warranty so not a problem.te on launch.

As others have said, at some 80% more than the GTR the 911 has a somewhat hollow victory here. And if anything, the margin was so small it's barely a victory at all.
Bit of a foregone conclusion but enjoyable nonetheless. If only there was a comparison of a rolling start to give the Hellcat just a slightly better chance.

I thought he was saying that because it broke - or at least had some sort of failure - in the video.
Did you watch it?
After 2 or 3 launches the GT-R's gearbox software will not allow any more launches under certain conditions are met, hence the software protects the box. That's by design, that's not a failure.Did you watch it?

.) and not claiming GTR box is trouble free.What I do have an issue with is pub-grade "facts" that have little support in even remotely scientific experiments.
If one wanted to test this issue, they would have to take a small sample, say 3 to 5 GTRs and 911s (each) and keep launching them (in the same conditions - ie. just drag strip them for a day) until the boxes go pop. That way you'd know what is an average reliability of a box based on a small sample of cars.
