Quick question, I know that the G85 pkg. comes with recaros and LSD. But don't they all have some sort of LSD? My SS/SC will leave a single burn mark in first gear then I hit second and both tires grab and leave about a fifteen foot dual burn marks, is this some sort of LSD? Sorry for the ignorant quest. just want to know a little more about my car

 

the regualr diff , is what is considered a open diff


it all depends on alot of variables , but it isnt uncomon for a open diff to leave 2 marks

 

I assume it depends mainly on surface conditions.

 

Yes, it's very dependent on surface conditions.

Put your car one tire on grass/ice/mud, one tire pavement(doesnt' matter which one) and gas it a bit. You won't move. The tire on grass/ice/mud will spin away.

An open differential applies power to the wheel with least resistance. In the event that traction is equal, it will evenly distribute power 50/50 and it is certainly possible to leave dual burnout strips.

 

This is talked about again and again.

Limited Slip on a FWD vehicle is way to over-rated. And for those who are knowledgeable about Limited Slip would know that unless it is a locker 90% of limited slip units will still spin one tire when on ice or mud.

 

Thanks for taking the time to answer my question

 

I saw a cobalt base model burn out on streetfire.net and both wheels were pouring smoke

 

codyss, how often do you drive your cars on solid ice or through mud pits? If it is a quality LSD, it will get power to BOTH wheels, like its supposed to.

 

Well I think I know what I am talking about, Sorry.

No LSD no matter who makes it is 100% unless it is a locking differential or a spool is being used. No clutch style cone or plate (Auburn, Borg-Warner) can have enough pre-load to do so or it would bind making it basically locked 100% of the time. And a gear type differential (Torsen) needs equal traction to both wheels or it too will spin one tire only. Even a differential with a centrifical engaging locker will spin one tire for a second or two.

I have had vehicles with all of the LSD listed above so I would know. Even the almighty Quaife is based of of other peoples designs.

In mud or on ice both wheels will spin due to the fact that both wheels have no traction. The whole one tire on ice and the other on concrete story is BS.

 

I am aware of most of the above. I never said it will get power to both wheels 100%, but it will get a hell of a lot more to both than an open diff.

I disagree however, with the Torsen needing equal traction. I'll admit I am not a LSD genious, so ill speak from an experiance. One of my buddies and i took our cars up to a parking lot to screw around and do some donuts cause we were bored... He drives a 1999 Camaro SS with a 9in (thanks to the t-56, dominator of rear-ends) It's got a Torsen. He (somewhat conveniently) started off with one wheel in water and the other on dry surface. When he punched it, definitely both wheels were burnin the Khumo's up pretty well. I'll get technical when i feel like the need.

 

yeah, lsd on a fwd car is MOST DEFFINITLY NOT OVERRATED!

 

Well a Torsen does require equal load. Thats why most F-Body guys upgrade to a Auburn Pro series.

And on this site LSD is over-rated.

 

You don't know **** buddy. All talk and nothing to back it up with:

http://www.quaifeamerica.com/

"The Quaife also controls loss of traction when the front wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. The Quaife Differential provides constant and infinitely variable drive. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs."

 

Once again CodySS has made himself look like a fool on this forum, when r u going to learn buddy?

 

Unless you're on an autocross course, that's the only place I've noticed a difference in LSD vs non-LSD cars. Everyday driving, yeah, unless you're in snow, ice, or other low-traction situation there really isn't much of a difference between the two. But put it on an autocross course, especially ones with hairpins and tight radius turns and that's when the difference really shows up. With and LSD you can actually get somewhat decent acceleration out of those turns where as my SS/SC with no LSD will sit there and spin the wheels until it gets traction. Even out on the track, I've never had any situation where I've noticed my lack of LSD because usually you've got a lot more momentum to pull you through turns and you don't rely as much on hard acceleration in extremely tight turns.
