Ok...

This is gonna sound like a childish post however I was wondering. Is it possible to do a burnout with the L03?

2.73's Suck

sure, hold the gas and the brake down at the same time:rockon:

PyRo9862

I can spin them for a couple seconts without holding the brake. Alot of times it will spin a little on the 1-2 shift as well.

And I thought the right way to do it with the brake was to put it in first, hold the brake, rev it up, then let off the brake.

ThraxXx

Wait a second...hold the gas and brake down? Wouldn't that wreck the back brakes?

PyRo9862

Yes.

Yeah, you're right...Childish. It's called a brake torque. Hold the brakes just enough to hold the car back, hammer down, when it is up in RPM let off the brake. It doesn't ruin the brakes but does cause premature wear. Or you could get a 350, LOL!

Twilightoptics

It's called all kinds of things.

Most people that a Brake Stand.

Is a good way to fry a centerforce clutch

Hold the foot brake down, mash the gas, tires spin. Easy enough.

When you get some power then you can just mash the gas and leave a 100ft trail w/o the brake.

2.73's Suck

it doesnt hurt the brakes anymore than when you stop
just let off once they get spinning and have fun! (brakestands are the one good thing autos are for ) and to cya, consistancy(sp?) on the dragstrip

hot86z-28

yeah, typically breakstands, burnouts, power jacks, etc... are not great on the car, i have heard a few stories about people breaking things. but it's easy enough to do, like people said above, but IMO it looks dorky as hell in an l03 b/c most are non-posi and have the infamous one wheel peel, where just the right rear tire spins, so it looks goofy. but to answer the question yes you can do it.

Its possible to do brakestands with jsut about anything... except an LG4. Again, not good for the car. Ive never really been too keen on wheel slip. Thats power thats not going into driving the car. Granted, having the rear mirror full of smoke after mashing the gas down looks kewl, it does nothing for performance.

hot86z-28

dont knock the LG4, i did a good number of smokey burnouts with the old SC, granted not quite as good as the one in the IROC where smoke was coming through the A/C vents, but that's beside the point the only real problem i could see you encountering is if at every corner your smokin the tires, peelin out, etc... or if your cars in really bad condition and stuff is just waiting to break. trust me i've done my fair share of the such and have had nothing bad,( other than one incident, where i got to cocky), so just go have fun and dont run it to hard.

AJ_92RS

And it's MUCH easier with rear drum brakes. If you have rear disc, it's more likely to wear the brakes faster IF you're able to get them to spin at all.

305LG4Cutlass

^^^ Are you trying to say that you can't even do a brakestand with an LG4? That's BS. I have 2 LG4's and I don't have to brake torque either one to spin the tires. The winter beater stock 86 Caprice w/700R4/2.93 will light up my brand new 235/70R15 winter truck tires with big lugs on them halfway through first gear. When I had the bald 225/75 winter tires on it I could screech the tires almost to the top of 1st gear!

My 87 Cutlass with 2004R and 3.73's will spin the 235/60R14's to the point where the car doesn't really move from a stop. If I ease into and put it to the floor it will lay rubber to the top of 1st and then screech into 2nd for almost 2 seconds. When it had the stock 2.73's and single exhaust it would still light them up pretty decent from a stop.

They might not be fast but they have enough torque down low to rip the tires up pretty good as long as the carb is working right.

btw this is with open rear ends, but I did have a 3.42 posi in the Cutlass for about a month (long story) but it would light up the 235's and kick the car sideways back and forth.

Whats an LG4? These names for the engines don't make sense to me

PyRo9862

LG4, L03, L98 and a whole bunch more are all RPO codes. The LG4 was a carbed 305, it took me a while to figure out just what the were too when I first came here and heard the names.
This should help you figure out what is what.

Very cool. Thanks for the link. I bookmarked it for the future.

This was an LG4 with 245's, 2.73's & posi. Wouldnt do a burnout for the life of it.

IROCtheRoad

My 305 can peel out ALL day long. But I have a question; twice i've been able to chirp the tires into second, but only twice. Why is that? Once was in the morning and the other time it was a hot summer day, so i dont think the weather had anything to do with it.

305LG4Cutlass

^ Well I can see that one not being able to do a burnout, but it should at least be able to do a brakestand. If not something isn't tuned right.

dimented24x7

iTrader: (2)

Its been a long time but it was tuned ok, jsut with the sticky tires and disk brakes from the previous owner it wouldnt do a brakestand. Just sort of sat there against the tc not really doing anything.

305LG4Cutlass

Okay, well I've never had any experience with disc brakes so I guess that could make a big difference. But that would be the extreme worst case scenario for trying to do a burnout. LOL. I had an 83 Grand Prix with a 231v6 (110hp) w/2.41 gears. That thing wouldn't even spin one of the bald 215/70's on it unless I punched it while going around a right turn. It would do a brakestand though. The last time I drove that car we did a brakestand for about half a minute and the smoke started coming in the backseat of the car cause the trunk was so rusted out.

dimented24x7

iTrader: (2)

That car was pretty much the only one that wouldnt do them. Even my 4.3 L blazer could cook the tires if I stomped on the gas and the brake at the same time, but then again I think it had decent gears.

TiMMaH668

hmm my lo3, t-5, 3.08, 235/55/16 combo doesnt seem to have any trouble at all laying rubber through 3 gears. and it is basically stock. guess its how u drive it. if you just got your car wait a couple months till you are used to it, when i first got mine i couldnt burn out or shift for the life of me. now i can chirp second nicely and kick the backend a bit in third. click the siggy for a demonstration of me and my buddys lo3's having some fun.

hot86z-28

i dunno about this disk brake theory. my 89 IROC had 4 wheel disks and trust me it had no trouble layin some rubber. but get a feel for the car and then go for it, if you break somethin, replace it with better stronger parts and then go from there.

90RS305

Gah, I can do burnouts all day long with my LO3/T-5 combo! It's hard to do, but I can do a breakstand with my car too. You have to use your left foot for the clutch and turn your right foot sideways for the gas/break....takes some practice but done right 3.08's aren't hard to get spinnin'. LOL my first set of tires I bought for my car were rated at ~70,000 miles and the steel radial belting was showing through the tire at 15,000...


Bruce (90RS305)

PyRo9862

I was wondering if you could get away with that. Buy an expensive set of tires with a big treadwear warrenty, then just kill them before its up and get free replacements. So long as you rotate them so they are evenly worn they cannot prove abuse can they?

90RS305

Yup! I got to use my warranty!!

PyRo9862

Wow, i'm amazed they gave it to you after 15k, where do you get your tires?


Damnit, I was hoping it was a chain store I could find around me

90RS305

Discount Tire Co. Great guys!

Man, you people and burn outs. I personally hate wheel slip. In an ideal world, Id like to have zero wheel slip at all times so the car can accelerate as quickly as possible. Theres nothing I hate more when I tip the throttle in to get going (usually in a hurry) and the back tires break loose.

dimented24x7

iTrader: (2)

To that video above, I take it it has an open rear? Those open rears really allow that outboard tire to put on a good head of speed. My friend egged me on about how far an open rear would allow the tire to spin and man, it would go for blocks. Jsut stuck the accelerator down and smoked out the whole street. Really makes me apreciate even having posi thats partially dead.

305LG4Cutlass

^ Man, burnouts are about having fun. Your starting to sound like one of those ricers that has a fwd with 110hp and says, "Yeah, well my car has better traction than yours".

At least with my LG4's, I really don't have to worry about barely touching the gas and spinning real bad. If I do a good burnout its usually (depending on the road) because I punched her to the floor real good. If I really need traction I can ease into her and get minimal wheelspin.

PyRo9862

Last I checked burnouts did slow you down...

89TA383M5

My LO3 has no problem spining one tire. From a dead punch it will spin to the top of first. If I brake torque it for 1 second it will go into second. Just bought the car and it needs a tune up and it still has nuts. Now my TA is a different story. 1st, 2nd 3rd, and 4th down the street smoking the tires fighting the steering wheel to hold it straight. I love American Muscle.

pecha

here's my former LO3 that can answer your question

Uh oh, gonna have to reach through my monitor and slap yo *** . Lol, J/K.

I came to detest burnouts at college. Every day on my way back to my appt. Id have to make this turn into traffic. Everytime Id have to get going in a hurry, the car would jsut spin through every gear with the peg-leg. It was so bad everyone nicknamed me 'one-wheel peeler'. The last thing I wanted was to be laying miles of tread with an 80,000lb peterbuilt doing 60 right behind me. Ive always found the exilerating squished into the seat feeling to be much more gratifying when I lay down on the gas.

hahahahah I get a kick out of how some of you guys talk.

"But... but... you mean floor it? isnt that dangerous?"

ssxmac

iTrader: (1)

Burnouts are fun, but there is something very gratifying to lining up next to someone and just getting a little 'chirp' on your launch. then being thrown into the back of your seat by those 255ft/lbs of torque.

LO3's can burn good, i got pulled over for laying a couple hundred foot patch out of a bowling alley once, luckely my dad had hired the guy !


btw, i need gears and limited slip

dimented24x7

iTrader: (2)

One thing ive always liked about a right wheel drive platform. The car can transfer (sometimes quite dangerously) its weight to the rear wheels which allows for accelerations up to and exceeding a g. Cant do that weight transfer if the car starts peelin' out.


^
Is your dad a sheriff or something?

90RS305

I've heard rumors and actually experimented myself that if you back up about 5 feet before you launch (if you have limited slip) it loads the lilited slip and that will give you momentary posi on a launch. From what I have done, never got a good launch (driver error) it does seem to work!

Bruce (90RS305)

Pablo

iTrader: (1)

limited slip and posi-traction are the same thing

if you have an open rear you have neither


and yes, I have heard that too about going reverse before launching if you have a posi that is worn out it will help keep it tight

305LG4Cutlass

The first day I got my dual exhaust, I took 3 friends out for a rip. Come to think of it I still had my 2.73's back then, but I only had 215/75R14's. Anyways I did a big burnout through this little intersection in a residential area. Next thing I know theres lights comin up behind me. Yep coppers. So they pull me over. Can't remember what the guy said to me, but he didn't act angry or tough at all. Just asked me to keep it down a bit at night in these residential areas because people start complaining (I can understand that LOL). Then he asked me if it was my car. The way he asked, it kinda sounded like he really liked the car. I think it might have been this guy around here that has a 5.0L Mustang done up a bit.

90RS305

Ohh... hmm... interesting.... Now I'm a little confused, cuz when I did that I got BOTH tires to spin for a few seconds. I know it wasn't some kind of fluke cuz' I did it more than once. You by chance able to explain why? I don't think the fact that mine is 3.08 would have anything to do with it, or would it....


Bruce (90RS305)

Dewey316

equal traction loss by both tires, even on an open rear, will spin both.

90RS305

Hmm...think I get what you're saying, but still a lil' confused... Based off what Pablo said, it seems to me there is NO connection between the diff. and the back left tire. Is there something on an open rear end SIMILAR to limited slip?

dimented24x7

iTrader: (2)

There is a connection in the diff b/w the tires, its the planitary gears (aka spider gears) tied into the diffs housing that serve to balance out the tire speeds. In a posi/limited slip or what have you, there are either clutch packs or clutch cones in addition that lock when large ammounts of relative motion are present but still allow for a small ammount of motion so the tires dont scrub around turns.

dimented24x7

iTrader: (2)

What your probably seeing is the inertia of the wheel itself and that causes the other to spin momentarily. After that, the power will simply take the path of least resistance, which is usually the pass side tire since, with a stock suspention, its unloaded by the torque on the rear end.

Dewey316

what demented said. BUT, the reason only one spins, is because the planetary gears will spin around each other, if 1 tire has more traction, the traction will serve to keep the one tire from moving, the power will go to spin the other axle and gearset, around the other. this is the reason, that when you lose traction with an open rear, that the tire will spin at twice the speed that the speedo reads.

if you have completely equal traction loss, both tires, can will spin. as there is no resistance on the 1 tire to hold it in place.

they had a really good write up on open rears, and auto trannies. Auto trannies are so confusing....
