well, it wasnt really a burnout, but when i torquebraked and gave it a good amount of gas, my left rear tire left a track while my right one didnt do anything. i have done this before in my dads jeep grand cherokee, and the right rear tire is the one that spins. it seems that most peg legged cars spin their right rear tire.

what does this mean? is it possible that i've got some non working posi in the rear?

 

nah man Fbody open rear cars do whatever they feel like my 1985 Berlinetta spun both rear tires 6 out of 10 burnouts thats why i put that rear in my 91 RS

open rears work like this
whenever there is an unequal amout of traction on both rear tires 9 times out of 10 the car will spin the right rear tire

when the traction is equal on both sides the rear locks posi

a good way to get V6 Fbody cars to pin both rear tires when doing a burnout is to first

1.)put either 255/6015s on the rear or bigger (recommend 275s)
2.)when you power brake it pull the shifter to 2nd gear
3.)when you power brake it very slowly increase the rpms this slowly puts pressure on the rear causing it to lock
4.)when it begins to spin both rear tires NAIL IT and watch the smoke fly!!!

 

You my friend are a prize..... "When traction is equal on both sides the rear locks"? Really? On an open rear end? You are clueless and are giving bad info.

 

Thank you. What he's described is a limited slip differential, aka Posi.

I believe an open rear CAN spin one or the other wheel, tho. Is it always the left? If so, I'd suspect something, and probably pull the diff cover to take a look-see...

 

Just checked the vid of my friend doing a b. torque in his '87 bird...yup...RIGHT wheel is the one going up in smoke.

 

my 85 spun the right, my 82 spun the left, and my 89 spun both, while a astro spins the left a 95 siilverado spins the left, and a 94 explorer couldnt spin tires in the rain..lol

 

Recommended 275's? Wow. I really had to try hard to get my old P275/60r15 rear tires on a 15x8 steel rim to spin.

 

I lit up the 255/50/16 Eagle ZR50 on the back of my 2.8... From a stop, I can actually burn all the way through 1st. If I drop the clutch, and jump on the brake, I can sit and spin until I run out of gas. I really gotta get a pic or two of me doing that at the track....

 

Well actaully he is partially correct! So don't jump to fast. I think he could have worded it better though. He is right though. Usually the Passenger tire will be the only tire to spin in a open rear, but like he mentioned, when there is equal traction in a certain spot both tires will spin similar to a posi. A true posi will always spin the tires as long as it is still in working order. So slow down with your name calling and find out info before you judge so quickly. Cause he is more in the right then YOU!

Oh so you know..I have a open rear right now, and both tires light up quite often. After 2 months you seem to know all there is to know..Sorry don't think so...

 

Riiiiiight. That's a pretty vague statement.

The guy said to get 275's for a V6 and you're supporting him? The original post was for brakestands, so I must assume we're dealing with auto trannys. It's going to take a lot of work for that motor to turn even one tire at that rate.

 

Dude I am talkling about the fact of the open rear factor not spinning both tires...please re read what I really said. Don't just read what you want to see... I mentioned nothing about tires, did I? No I did not.

 

Oh yes and one more thing 275 is the width of the tire, in case you are confused, a taller tire may make it harder to spin, more then the width, for the most part anyway. What makes you think you can't do a break stand with a Stick?? I use to do them all the time with a M21 muncie. with ease!:lala:

 

You are an I%^#@...Point blank. Open rear ends will not, never, or even in their next life ever lock--&^%$#&* *&^%$ *&^%$#%$^---- I swear! Kids and their bad info- You have no clue who you are trying to school youngster.

 

Kid!!! lol!!! Well I guess you know all..don't really matter to me old wise one! I'm not going to turn this inot a total flame so good night to you. all mighty one.... My open rear on my SS spins both tires almost 70% of the time..And no it is not welded or anything... It's called equal traction... Figure that out...:hail:
