991 GT3 Clutch Kick. Is anyone using it? - Page 2 - 911/Carrera GT - PistonHeads UK

This pulling both paddles for clutch in is really confusing me. I just cant work out when and how to use it. My brain just cant convert what could be done with a pedal in to what can be done with a paddle. Any thoughts?

Its quite straightforward to use, but my advice before your practice is to find somewhere with plenty of runoff space...!

I use it quite a bit but mainly when coming to a stop or over speed bumps to smooth out the jerkiness so in effect im coasting. Its also handy for pulling away at more than tick over for when you are going slowly towards a round-a-bout and need to pull on to it with a bit more oomph

1. Drive along road 2. Wind windows down 3. Enter tunnel 4. Pull both paddles 5. Use accelerator pedal liberally 6. Pull both paddles 7. Exit Tunnel 8. Wind windows back up.

Yes, that seems to be what most will use it for or you can just knock into neutral for same effect. I guess this feature that AP felt so important has no real world use? I tried something with it today and it certainly wasnt mechanically sympathetic.

It is basically an invention purely for Chris Harris, so he didn't have a go at the lack of manual. Having said that, will definitely have a cheeky few gos on european trackdays to hone my drifting. Can't do it in the UK anymore; you just get black flagged. I suppose a few years down the line in adverts it'll be about having a car with no clutch kicks logged

A clutch kick in a manual car involves revving the engine quite high with the clutch down then abruptly clutch kicking (release or dumping the clutch). This allows you to easily power slide a car when there otherwise wouldn't be enough space to get the revs up to do so. This feature of the 991 GT3 does sound pretty cool, but despite being even easier than a manual car, I'd expect the number of owners who could use it effectively to be very small indeed.

It appears to be none!!! Not one person has replied who has 991 GT3 and uses/knows how to use it. Not one video of it on You tube. Hardly a mention via Google. Ive played with it a little more today and still have no idea at all how to do anything with it and before the idiot who doesn't give driving lessons pops up again I am a very experienced driver so I can tell you there's nothing obvious or simple about it. Anybody?

Ive found someone.... Richard Hammond. He says... "The gearbox does, however, have a very good party trick: Porsche calls it “paddle neutral function”. First, disengage the traction control, then pull back on both steering wheel-mounted paddles and both the clutches in the gearbox will disengage. You then rev the engine to its redline and release both paddles. The result is an explosion of tyre smoke from the back of the car, crazy wheelspin, two black lines in the road and £250 worth of tyre wear in a couple of seconds" http://www.mirror.co.uk/lifestyle/motoring/car-rev...

Anybody? Sorry but your either very naïve or thick and by calling members on here that are trying to help you use a simple feature an idiot will get you nowhere im afraid! I replied to your post in ways to use it, I can't see what you are not getting

Im not getting any real world use for the feature that AP seemed so proud of and felt essential for the GT3 PDK. I hear how you use it but im not sure thats why its there.

It is quite handy when used as described above but all in all its just so the "purists" (Chris Harris and a few super heroes on here) have less to moan about by not having a clutch second best thing if you like! btw, I'm glad you're not thick

As someone peeking in through the window of the 991 two things always struck me as odd with the this feature. It always struck me as odd firstly that the both paddles neutral feature (this is what clutch kick is right?) was even mentioned. This seems to be a standard feature on paddle shift cars i have driven and has never warranted a special mention from those manufacturers. The second was that upon deciding to mention it, the situation that it is obviously most useful in gets no mention anywhere. Instead just that ridiculous clip where AP discusses dropping the clutch to let him go sideways in second gear in the rain!!! It would seem to me that the ability to save the engine and gearbox by hitting neutral in the event of a spin on track would be something they would want to remind owners. Going backwards in a car that has up until that moment being going forwards, with the engine and gearbox still connected is great for lightening the wallet but not much else.

I guess the point is that if you don't know what you'd use a 'clutch kick' for in a manual car then you're unlikely to be someone who tries this in a PDK GT3. I'm hoping to try this out at my PEC day next month.

Let's hope they don't need more than half a turn of lock while going backwards then

One purpose of disengaging the clutch via the paddles in the 991 GT3 is to momentarily break traction, and allow the rear of the car to rotate. Its exactly the same as dipping the clutch with lots of throttle aggressively in a RWD manual car There was a degree of seriousness about the "not giving driving lessons" comment anyway, I wouldn't want to repeat personal experience of how and when to use the clutch kick, only for someone to try and copy it and crash..! Which is why I'd suggest finding a deserted test track to practice

Ive been driving paddle shift for quite a few years now.

Thank you, much better.

http://www.pistonheads.com/news/default.asp?storyI... "There are quirks, like the 'paddle neutral' ability to open the clutches by pulling both shifters together. Porsche says this can "neutralise the driving behaviour of the vehicle when oversteering in a wet curve by pulling the paddles, thus redirecting the additional cornering force to the wheels of the rear axle." If anyone can explain the logic of what seems like dipping the clutch mid-oversteer situation I'd love to hear from you; for all the opportunities to try it my hands and head are too full for experimentation"

I just can't see how anyone could hold both paddles while twirling the wheel or loosening their grip especially in an oversteer situation. It'd be more effective to try and lock the front wheels with your Left foot if it's still rotating ? Unless Porsche are assuming it's going to end up rolling backwards

Paddle Neutral The “Paddle Neutral” function is based on the function of a clutch pedal on vehicles with manual transmission. On the new 911 GT3, this decoupling function can also be used for influencing driving dynamics individually, irrespective of the driving situation and the engaged gear. The Paddle Neutral function is activated by pulling and holding both shift paddles on the steering wheel at the same time. This opens the clutches of the Porsche Doppelkupplung (PDK) and interrupts the flow of power between the engine and the drive system. When both shift paddles are released again, the clutch closes with lightning speed if PSM is switched off (ESC+TC OFF) and there is a pulse-like resumption of the flow of power between the engine and drive system. If PSM is switched on, the clutch also closes quickly, but not in the same pulse-like way, when the paddles are released at the same time. The engaged gear flashes on the gear indicator in the instrument cluster to indicate that the Paddle Neutral function is activated. The Paddle Neutral function essentially offers two advantages. First, if the vehicle understeers in a curve (on a wet road, for example), this function allows the driver to neutralize vehicle handling. The interruption in propulsion force on the rear axle prevents further “sliding” over the front axle and allows the build-up of additional cornering forces on the wheels on the front axle. This functional advantage therefore ensures not only greater driving safety, but also improved driving performance as a result of faster stabilization of the vehicle. The second advantage of the Paddle Neutral function is due to the individual influencing of the driving dynamics through the pulse-like build-up of propulsion force upon clutch engagement. During dynamic driveoff acceleration in conjunction with the ESC+TC OFF function, for example, the amount of slip on the wheels can therefore be controlled individually using the accelerator pedal. ______________
