whats with everyones hard on with an lsd? and im not a noob posting on why i should get one, because i dont want it. i just dont see why its so great...

now maybe its the drag racer in me, but i love the feeling of both tires spinning and fishing it out around the corner. thats the was a rear wheel drive car should be. a solid axle is the only way to go, imo. now eventually ill take my car out on the road course and see whats up, and maybe ill realize what everyone is saying. but im willing to bet, and i could be wrong, that a good driver with a solid axle can keep up with an lsd. its not that hard.

i dont know a whole lot about the lsd's, but i know it follows the same line as the old posi-trac. i had a posi in my old chevy street rod, and it was just not that fun. one wheel burnouts are gay.

just lookin for an answer on why everyone likes that one wheel drive bs.

 

... Go hit pahrump with no LSD... You'll see why.

 

I thought E was the new thing now.

I had a blast when i was younger.

oh, sorry. wrong lsd

 

^^^ thats pretty funny bro

 

hahaha +1!

 

You have an incorrect view of what an LSD does. Here is a wiki that explains a lot.

http://en.wikipedia.org/wiki/Limited-slip_differential

BTW, The Z has a Viscous LSD.

 

ok. so its basically a one up on a posi, no? so basically the main advantage of an lsd over an open diff, on a road course, would be coming out of a corner i figure. right?

i dont know, i see your point, but i still dont think im ready to jump ontot he bandwagon

 

posi was merely both rear wheels having drive as opposed to one wheel having drive. LSD is for cars that have posi already but it takes into consideration what wheel needs what amount of drive given the experience the car finds itself in. It doesn't "shut off" drive to one wheel, it regulates the amount of drive to each wheel based upon what is senses is occurring. Viscous LSDs are the easiest to manage.

Don't get a two-way to drift til you understand LSD.

It basically senses which wheel is still grabbing and sends the power to THAT wheel in layman's terms (specially the quaiffe)

 

well that makes good sense. but i still dont really understand why you would want that to drift or drag race? especially in drifting, one would think you want both wheel spinning freely, not trying its dammed hardest to hook up?

 

In drifting you're gonna break loose. Might as well break loose under some kind of control.

In drag racing, you don't want to spin. It eats time.

 

Good read. This part caught my attention...

"Viscous LSDs are less efficient than mechanical types, that is, they "lose" some power. They do not stand up well to abuse. In particular, any sustained load which overheats the silicone results in sudden permanent loss of the LSD effect.[4] They do have the virtue of failing gracefully, reverting to semi-open differential behaviour, without the graunching of metal particles / fragmented clutches. Typically a visco-differential that has covered 60,000 miles or more will be functioning largely as an open differential"

 

I would just like to correct you a bit. A "posi" unit is just a clutch type Limited slip. It is just that GM coined the term "positraction" and uses it as a selling point. Where most imports started using the more relevant term "limited slip" or "LSD" to sell cars.

A spool permanently locks both axles with no slip at all.

 

So basically, are stock ones wear out. I have beat the tar out of my car, I now have 62000 miles. I autocross alot, so probably would help me out my upgrading my LSD, what would be a good one to get for my application.

 

Thanks, I didn't explain positraction very well. An example can be seen in the movie "My Cousin Vinny" wherein Vinny's "mechanic" girlfriend was able to solve the case of a car speeding away from the scene of crime. The Defendant's car was NOT the car because the crime scene showed the burnout skid of one wheel leaving the scene, whereas the kids on trial had positraction in their Pontiac (i think it was a Pontiac) which would have left two burnout skids.

 

yes, the clutches on a VLSD will wear out. if you autocross a lot and drive quickly, it was probably before 60,000. granted, it will still operate and seem normal, but the LSD operation of it will be diminished.

 

Your movie referencing sucks. The kids did not have positraction, hense two tire burnouts were left on the scene.
Duh.

 

What he said...what can I say, I'm dyslexic...you know what I meant

(my memory is shot and that's an old movie, jeez off the top of my head "My effing Cousin Vinny" was good pull)....

 

Obviously not since you got the base Z.

 

hahaha

 

ooh sick burn.... but true.
