Is it actually possible to do a standing burnout in the c8? I've looked everywhere and can't seem to find anyone or any videos of it being done. Drifting it seems to be straightforward but standing still doing a burnout seems to be scarce. I know about the "pull the paddles back to disengage the clutches" trick, but is it safe to do a burnout like that without hurting anything? I would have assumed I'd see more evidence if it could be done safely. My thought process would be:
1.) Turn off all nannies
2) Move to manual mode, 1st gear
3.) Pull paddles back to disengage clutches
4.) Rev to whatever rpm and hold it with brake engages
5.) Let go of paddles simulating a clutch dump
I'd try it myself but obviously don't want to break anything if I haven't really seen any evidence of it being done anywhere else unless someone has videos?

So in our TT shop car I have done this a few times at the track. Granted I did it in the water box so its going to take stress off the drivetrain. It was on a stickier Drag Radial Tire which will provide more grip and therefore more stress on the drivetrain and we had no issues at all.
My theory is that if it had the ability to hurt the car GM probably wouldn't have made it an option.

I have been interested in seeing video examples of this as well. I assume you are aware that it is described in the owners manual, as "rapid exit" mode. But, I will post that anyway, since its related to the topic. The fact that it is described in the manual would seem to suggest that the car should be able to tolerate it. But it obviously puts a good bit of stress on the car. I have not tried it, and probably won't.
^That sounds like a procedure for a typical burn out.
I think the OP is asking about doing a brake stand. A burn out, while holding the car in place with the brakes.
I haven't seen a C8 do it on YT either. They either seem to fight w/themselves systematically, simply bog down and do nothing, or move forward.in a weird, awkward way.

Launch control has literally been destroying axles. I've seen instances where it's happened on both the street and on a track.
I would *try* it even though the car is under warranty but the problem is the axles on z51 c8's are special ordered (and are on national backorder. Ask me how I know... lol). I already had to have one replaced and it took a miracle for me to even get one. If doing this were going to break something, it'd be an axle first guaranteed.

Yes, agree, thanks for pointing that out. There are two different procedures in the owners manual for a fast start. They are "rapid exit", the one I posted above, and "launch control". Neither procedure involves holding the car in place with the brake, while spinning the wheels. Rapid exit revs up the engine with paddles held, then released. Launch control involves revving the engine with brake held, but you release the brake to start the motion-the tires are not turning until the brake is released. So, there is no procedure for spinning the tires while holding the car in place with the brake-if that is what someone wants.

It's "standard procedure" for warming/cleaning tires at the drag track before making a pass. Also...it's just fun to do, occasionally.
Yeah. I've done it, or more accurately, my wife has, in my 66 Pontiac. It is fun.
Launch control on a sticky drag strip prepped surface may destroy axles.
Doubt the same can be said for a street surface since there is some wheel spin.

@djpelosi So did you try it? Is that how it's done for a standing/stationary burnout? I am almost at 500 miles and can't wait to try it out.
Engineering explained's video said for launch control if you hold it at the 3500ish rpm too long it's bad for the car, but the car he used wasn't a sports car, but does it apply for C8 Z51 as well? Is it harsh on the DCT and I should let go of gas fairly quickly when 3500 rpm is achieved during LC?

Even on street really? I was thinking on street it will spin some and won't be as bad on the axle?
lol did you do a lot of LC and broke the axle?! Dealer covered it under warranty right but Is Z51's axle still on back order? oh man maybe I shouldn't do it that much when I get to 500 miles lol, I waited a long time for this car!!
Edit: looked into it and axle parts and labor it's around 1k at the dealer, that's not that bad actually but will LC damage other parts? or just mostly axle since it's the weakest point?

It says at the rev limit let go of both paddles to do rapid exit, but it doesn't have to be at the rev limiter right? any rpm above let's say 3k ish will do ?

I don't know. I have not tried it. Since it does say the rate of acceleration depends on how far the gas pedal is pressed, it implies that full throttle is not required to execute a rapid exit. The term "rapid exit" is in the section on double paddle declutch, and refers to one of two ways to "exit" from the double paddle declutch, one being "Normal Exit", the other being "Rapid Exit".

Reason: add caveat
Every student at Ron Fellows gets to do several launches. With around 100 cars I wonder how many axels have been destroyed.

Yeah and they have classes all the time, last month I checked and classes are all booked up until end of summer! When I go to Spring M I am going to ask them is the break-in 500 or 1500 miles before doing launch controls, manual doesn't specify and some owners do it at 1500 some 500. Also going to ask how often to let the DCT rest after doing x LCs.
This is kind of a manual launch control, pull both paddles, rev to 2k, 3k depending on slippery the road is then let go both paddles, what do you guys think about that? I wonder if that's less harsh on the DCT.
Is the axle still in back ordered? Take a few months to get it?!
We have upgraded axles in stock for anyone that needs them!
We have noticed a lot of factory axles snapping at factory power levels and while we typically see them covered under warranty they still take a long time to get and their is no gaurantee it won't happen again!
These axles have taken dozens of launches at over 1000whp on drag radial tires!
The bottom axles is our upgraded version that uses a solid stronger axle bar versus the hollow factory unit.
In another social media they said other than the 2 snapped from 1.5, 2 years ago, they haven't seen any new report of it snapping. One that was snapped by username "toilets" in here, it came from a bad batch. The other one the detail of how it snapped wasn't clear.
But now djpelosi just snapped his recently and he said above "Launch control has literally been destroying axles. I've seen instances where it's happened on both the street and on a track." So I am pretty confused now, maybe djpelosi can chime in on if those are stock C8 /drag radial or what. The other place said stock C8 the axle got no problem.

I hope you're letting your customers know that this would end up causing their powertrain warranty to be voided if there were a major failure and the dealer was smart enough notice the upgraded axles.
