Same question as in the title will these destory the transmission or rear?

demonchild

well it cant be exactly good for the car...

MdFormula350

i like burnouts better, dounuts killed my 88 formula 350 9 bolt's posi.

brodyscamaro

i cant see them being good. i know for a fact that law enforcement (at least ours) does not approve of either. i have done at least 50+ burnouts on my drivetrain. done a few sets of donuts - but no more. they are too illegal for me...

oh well - if it cant hang it cant stay

edit: when i say burnout i mean at lease 45 seconds long

If they were good, there would be no need for this forum

Whether your whole setup is built for it or not, sooner or later, something is going to blow, unless you are into tearing it down on a regular basis. No ifs ands or buts about it. One reason why these forums are here; most people don't, and then wonder what happened.

I just did a couple of burnouts and donuts today ahhh stress reliever. Yeah, it's hard on the equipment but I'm not worried about the transmission or engine in mine, just the rear end. If it breaks, 250 bucks later I'll have another one in, no big deal.

Donuts aren't very great for gm rear ends. It puts a ton of side load on the rear end, and the gm c-clip systen isnt exactly the greatest thing out there.

One time this nieghbor kid was pissed at me, so he figured he'd take his pos truck on my lawn and do a donut. He was quite shocked when his passenger rear axle shaft just popped right of of his rear end.

I charged him $200 to fix it, and then i pressed charges against him.

2.73's Suck

Yes.

PyRo9862

Ok, so ill stop doing these so much Thanks guys, just curious

snowman89

I herd that doughnuts aren't just bad for the rear end....since camaros are unibodys don't they seem to get twisted or bent when we do doughnuts????? Thats why they have Sub Frame connecters right???

idrag2

think about it when you do a doughnut your putting all of that stress from you axles moving in and out on the center pin in your rear end, sooner or later something is gonna break. Have you ever noticed that when you jack your car up you can grab your axles and move them in and out just alittle, and I mean alittle. I have broken spiders the center main pin, and this last time broke a whole carrier!!!!!!!! But thats just my .02

Of course they're hard on the car. So is power-shifting, drag racing, auto-crossing, etc. But these are the things that make our cars sooo much fun.

Abuse it until you can't afford to fix it, that's my philosophy.

(Note to self - Is this why my car has been stuck in the garage for the last year with a busted tranny & rear-end?? Naaah!)

It's just "testing" until something breaks. Then it's abuse of power and you hang the parts on a wall and post pictures, etc, then fix it accordingly and try again...

RJR99SS

i knew an engine builder who would test out an unused engine and drivetrain he just built by just bringing the engine up to about 5 grand, dropping the clutch and doing a burnout. His theory was that if anything was going to break...it would break then.

In pure racing terms...i guess that is pretty much true.

Ed Maher

ROFLMAO....not exactly when you want to find out that the brakes don't hold, or a motor mount breaks jamming the throttle, or the seat mount was loose and you fall in the back seat, or ....

RJR99SS

well interestingly enough, he retired when a flywheel came loose, shot through his floorboard, dash, and out the roof of the car. Somehow it didnt maim him either.

Well...it's still a good theory.

87 Firebird

Rotflmao....that's pricesless stuff. Did he have the clutch pressed down when this happened and whas revving the engine or what? Geez, that's what would be called a leg-remover if it had flown to the side instead of upward. Wow

Dewey316

just a thought here, but wouldn't there actualy be less stress on rear-end parts, if the tires are spinning? going sideways or forward, if the tires are spinning, there isn't the resistance of traction

TheGreatJ

It's the shock-load of initially breaking traction that blows things up during a burnout. Once they're spinning it isn't so bad (except for the tires.)

With donuts the big issue is side loading.....like RJR99SS said C-clips aren't the best design for withstanding side-load.

87 Firebird

Yes and no. When going forward, there is always the pressure being placed on the system by rotations, by resistance, etc. The difference is that the system is DESIGNED to withstand those pressures. When going sideways, It's putting thrust pressure on the works, which can cause gears to be eaten much faster because the tolerances are being changed

ive never broken something when burning rubber, ironically ive only broken things when i had traction, smoked two clutchs at the drags in the burnout box. donuts probably will wear out the posi faster but i think their kinda fun. i get a little crazy with my burnouts too.

Dewey316

doesn't the same apply for lateral movement too, once you break traction the force should be alot less. i would think with some sticky tires, road racing would put the most force pull and pushing on the axles.

i am not trying to argue, but in my little mind, the most stress on the parts you are mentioning, is when there is lots of traction, not lots of sliding, spinning, smoking, ect

this is why we see guys on slicks break axles on the launch, because that is when the most force, and shock is being transfered to those parts, on street tires, you break the tires loose before you overstress those parts.

I can tell you that both burnouts & donuts, while really cool, don't agree much with a T-5 Tranny, not sure about autos, but sure its not good on them either.

resinlake

On my Iroc, blow transmission mounts all the time, and rearend has to be tied up every month and a half or so. The rear end has been replaced once, as well as two sets of gears. yepp, those donuts and burnout sessions take a toll =))

Some how i managed to break off an exhaust bracket doing a burnout. probably from the back end sitting down when i got on it. From what i've been told burnouts are really tough on U joints too. I agree than burnouts and doughnuts are fun though. Especially when angry. How else is the drive through fast food place going to know if they screwed up your order? Rock on

resinlake

maybe that would be why my driveshafts on the verge of falling out??? every time the car gets put in gear you can hear the transmission slap the underbody. too much torque ya think?


keeeep on burnin!

Abird4u2nv1

iTrader: (-1)

If ur trans slaps the underbody that sounds like a trans mount.

strokedtpi

wow...i should really stop whippin donies before i break somethin

thanks for the specific info fellas

strokedtpi

yeah that slappin is prolly a tranny mount for sure had that in the old formy a few times--from experience i dont think the polyeurothane one is any better than the 12 dollar rubber--they both break..

resinlake

Well... if its the trans mount (cost $7 for a rubber one here), then i must be breakn it every time ive put one right back in =), and no the poly ones are good, but the damaging force is then subjected to the rearend. Learned that from a drag racer. So, if you are going to build up your tranny, build up a rearend really good, umm but personally, Id rather just replace rubber mounts, its pretty easy anyways.

2.73's Suck

LOL! stupid drive thru asses

Yea and make sure the torque arm mount is tight! I had a bolt fall out and let my torque arm fall out the other day!!! Talk about rear end grinding! Took a u joint with it! Got it fixed b4 anything got hurt tho.

resinlake

when taco bell goes and messes the orders up late at night, youve got the whole wal-mart parking lot right there to do the donies in here =))

Tobias05

anyone ever get crazy dash shaking noises? I've gone slidding around in my school parking lot a few times and my car always sounds like its gonna break in half... could wheel hop have anything to do w/ this? What about havin a 17 yr old car ?

brandon

ronterry

I must be the only person to ever get a ticket for doing a donie in a mall parking lot. HALF donie at that (I call it a turn around deal), and the parking lot was empty.
4 point careless driving if you can believe it!!!
I told the cop that this is the most retarded thing I ever got a ticket for. That pretty much sealed the deal
That statement came back up at plea bargaining, and I told the DA - "I stand behind that comment 100%!"
I walked away with a defective vehicle ticket

Flyersman29

if ya don't have line locks your prolly rippin up your brakes too

GTABABE

yeah man you do enough burn outs and your trans clutches will strip real nice. trust me i have a gta sitting in my driveway because of it. as far as donuts i'd say they put some strain but i wouldn't say they are as bad as burnouts. but close to it.

Beefy89

If something breaks, it was gonna break anyways..

my84firebird

Well I did a neutral drop into a burnout after work today for the first time since I got the tranny redone, and now I have a bad tranny mount......

IROCThe5.7L

Neutral drop after your tranny was rebuilt....You must have deep pockets

my84firebird

No, quite the opposite my friend. My car would look alot nicer if my pockets were deep.

In all honesty, the tranny was rebuilt in October and I pretty much drive like an old lady 99% of the time, but I was showing off in front of some coworkers, bye bye tranny mount. My fault though, neutral drops are the devil....

ronterry

Never - Never - Never do neutral drops!!!

I did ONE in a loaner car - ONE!
They had to tow that loaner off, and bring me another loaner car.
I think it broke the output shaft?

As far as burn outs, I stopped doing then after I kept replacing two hundred dollar a piece tires every 6 months.

Longer91Cam

You know whats really cool? My 91 RS 305 can barely turn the tires over, or should i say TIRE. My four banger s-10 can light em' for a longer time. I must be doin something wrong, or it might be the fact the car is slower than ****.
