DCT power braking and burnouts/launch

[michael3435]

Hey guys,

With the DCT, can I just power brake it (meaning hold the brake and mash the accel to burnout then take off)? does this do much damage to the front brakes?
I assume the rear brakes deactivate when the gas and brake are pressed simultaneously?

sometimes when I try to use launch control it doesn't activate for some reason (maybe I haven't driven long enough I have no idea) but when I press the gas down to kick down the car just juts forward and I look like a tool so I was wondering if it safe to just use the aforementioned method?

Power breaking won't get you anywhere. Many of us have found this out by failing the launch control setup. If you want a good launch use launch control assuming the road is flat and wide enough for comfort, or feather the throttle well. If you want a burnout just mash the gas.

I love power breaks..refreshing

So I tried to mash the gas while having the brake down today and it didn't feel good. Is it possible to powerbrake with the dct? Maybe I need to give more gas

I'm going to give my uneducated opinion and say hell no.

There is no torque converter you are loading up. Think of it as trying to take off in a car with a manual transmission while you still have the e-brake on.

OP, there's no traditional torque converter in the DCT. There is nothing to pre-load so to speak in order to put peak power down when you let off of the reigns (brake pedal in this case). Theoretically power braking should be 100% useless in this car.

To answer your questions - no the rear brakes won't deactivate when the gas and brake are both pressed, as you assumed. Also, how many miles on the car? Have you had the break-in service performed at your dealership? If not, the Launch Control won't be activated. But the LC won't give you the smoky burnout you seem to desire - the idea of LC is the car putting down it's power as best it sees fit to get you moving at the quickest rate. In suboptimal conditions the LC will spin tires, I'm sure, but LC's function is not to keep the car in the same place under throttle.

You seem very concerned in doing a burnout, but it should be the simplest thing in the world, as long as you've got the power. Turn off all nannies, floor it, hold on.

When you floor it the DCT should leave the clutches open until revs build and then "drop the clutch". This will happen rapidly as you stomp on the gas, but this is the process occurring behind the computers.

Disclaimer - Don't be an asshole and do this on public streets, during busy hours, in a school zone whilst passing a bus flashing its children sign -- obviously. Find a large and safe space and learn what your car can do. Be responsible with this new power though, it's easy to get out of hand. See the Sakhir Orange car that learned to fly just a few months back.

use LC, raise the RPM and you'll get a lot of smoke

A working alternative to the stomp and hold on method.

All factual statements worth repeating.

I would add flat/level to that, as per the advice given to me on another thread on a similar topic (except I was trying to minimize wheel spin but OP seems to be going for a smoke show)

[CanAutM3]

I'll just re-iterate what others have already said, there is no torque converter in the DCT, so power braking is completely useless and will only result in clutch wear. And that is if it is even possible to "power brake" the DCT, not sure the electronics would even allow it.

^This, if you have revs at maximum with LC activated you will get what you wish for....trust me.

but when the tires are smoking what if I want to prevent the car from rolling forward or launching forward? there is no way of stopping or breaking the car?

Have you done the 1,200 mile service?

Once you have gotten the tires to spin, you can slightly press on the brakes to hold the car. See video below from EAS:

... Every time one fucks this up the shame is as hard to handle.

[babyboss]

excellent burnout ..

detail how this is done ?

Yikes. Bye bye Super Sports.

[buildbright]

I was going to suggest what did in the video. Brake stand like in a manual.
