why is it only one spining and not two??????????
what do i need to put to make both spin?????

 

one wheel spinning....hmmmmmmmmm that sux
you need posi

 

limited-slip differential

 

I hear that some Birds and Camaros come with limited-slip. Anybody know which ones. I belive my 89 just might.

 

Jack up the rear so both tires are off the ground. Now spin one of the tires... does the other one spin in the opposite direction? If it does, you have an "open" differential. If one spins when you put power to the pavement, then you may have a blown posi unit and thus too have an "open" (by default) differential. They do wear out after a while...

 

looks as if someones got a one-wheeler peeler...but we have proof that at least SOMEONE on this thread has posi!!!! lol broady

 

14.3 @ 98mph bone stock 305? Why does that sound funny to me? Do you mind posting your entire time slip?

 

Or did two identical peg-legged burn-outs.....

 

If you have an open differential each wheel is connected perpendiculary (sp?) by a small gear to a large gear. The large gear is driven by your engine (through transmission and other stuff, blah blah).. When both of your tires are on the road they provide mostly equal resistance and thus they are turned by the larger gear.

When you peel, one of your tires loses traction first (the chances of both doing it at exactly the same time are miniscule). It provides much less resistance and it's thus turned much easier.

So, there's no way that both of your tires would peel because almost all the torque is transferred to the wheel giving less resistance -- in this case -- much less resistance, the wheel that lost traction...

This gets tricky when it happens and you don't want to impress hot chicks or whatnot...

Limited Slip Differential, SLP, Positraction, etc. are all a name for what is pretty much a spring that is put between the two small gears.

When there is a big difference in torque transfer (i.e. the two small gears turn at a significantly different speed) the spring begins to exert a force on the small gears, effectively locking them, and thus transfers some torque to the wheel that offers higher resistance to movement. Result: both wheels peel...sometimes.. (depends on your torque output, strength of the spring, etc.).. that's why it's called limited-slip, and not no-slip...

Now, Positraction is a cheap hack, there's also viscous coupling (used in rally cars), which uses thick fluids, and TorSen which is computer control hydraulic torque sensing differential, but now you're talking some serious $$$$ ..

The main reason you have a differential is because sometimes you want one of the wheels to rotate slower, such as when you are in a turn, otherwise your tires, traction, driveability, etc. would suffer... Some World Rally Championship cars have a locking switch so they can choose when they want the wheels locked-up..

Try left-foot braking, that might transfer some more torque to the other wheel.

:nono:

 

That looks just like a "Slippery When Wet" sign.

 

I have a 89 TA. It had an open diff. So I was a one wheeler peeler!!

No I have 3.73 with posi!! Way better!!

 

if your getting that from your 91 z28 then the posi is either worn out or someone removed the original rear. 90 and up z28 models came standard with limited slip. for going cheap i'd recomend a torsen take-out from slp.

 

:rockon:

 

A spool

 

Get a Powertrax LockRight locker. That's what I did. Works great and both wheels turn at the same time. Does killer burnouts.

 

I have a 1995 Chevy that has been LS swapped and no matter if I’m on asphalt or gravel I can only get one wheel to spin during a burnout. Everything else is stock. Why can’t I get both wheels to spin.

 

open differential? You need to limit to one post this is an old thread.
