For those who are curious, it does exist and it works very well.

Follow these steps to activate and use:

1.) Make sure car is at operating temp
2.) Sport mode is a must (traction control off and sport suspension are optional)
3.) Depress brake pedal completely and hold
4.) With brake pedal held down, floor the accelerator. If done correctly, revs will build and hold at around 5000rpm
5.) Let the boost build a bit; let off brake pedal to proceed with motion (or let off the accelerator to abort)

Unsure about how this affects the PDK, but I'd assume all the logic that surrounds SC launch control applies with this. Don't go crazy and back to back with it. Use it responsibly.

This is similar to a 991.2 7M feature that was pointed out to me at my ATL delivery by the techs..

At stop with the clutch in, the engine will hold revs (I believe he said 4k RPMs), them conceivably you would dump the clutch.

He also said don't do it, not advised.

I think I'll follow their advice.

 

I discovered this a while back and brought it up to a salesman that a non sport chrono car has LC. He sternly denied the fact.

It totally works and can be done in sport mode in cars that have SC.. A soft launch.

 

"Porsche salesman hate him for discovering this neat trick"

 

I wonder why not? It does not seem that out of the ordinary albeit I have not tried it, yet.

 

the missing item is Sport+... pdk doesnt shift as hard without it. but yes, launch control exists in non-sc cars.

 

THIS ONE NEAT TRICK!

 

The rev-limiter at a standstill may have to do with "hidden" LC but may also be there to limit engine damage (esp w/cold oil), emissions, social annoyance, etc. Can look into, but it's of little interest to me—as a 911 has a lot of negatives when it comes to dropping the clutch: weight on the rear end, size of rear tires, and a lack of torque down low (particularly on NA cars) all add up to a huge strain on expensive mechanicals where, say, a V8 muscle car is literally ideal to "light em up."

In all the years of testing 911s, there's only one with a MT that I have dropped the clutch in: the 997.1 GT2 (and then only because Weissach engineered a very interesting LC system to build boost and made a point about it). And...it was fun.

 

Awesome find, Tks. Time to break out the dragy...

 

Dude take the clear plastic off the PCM already...

 

Eeekk.
The finger prints tho...

 

A full,wheel-spinning clutch drop is very hard on the clutch, especially in a 911 with so much weight on its driving wheels. The 4000-4200 rpm limit was new with the 991.2. On earlier cars you could perform a clutch drop over 6000 rpm. Use the right rpm for the traction conditions and the spinning wheels get the car going and when the tires hook up, the engine should be in the meat of the torque curve and off you go.

 

what is running on your phone below PCM?

 

In addition to Valvefloat, Porsche clutches are relatively small compared to Ford or Chevy, why never recommended to hard laugh a MT. Pdk is a different story
