Which kind of LSD do you prefer? Cast your votes...

 

I can't stand clutch, give me a torsen.

 

Torsen Cause I just got a use one from a 93 fd. hope it will work on my TII

 

Wish I could afford to even think about that right now..

 

I have heard bad things about Torsen LSDs...can anyone confirm?

 

what have you heard? they are great they are predictable, don't change with time and do not need additives in the oil.

 

See those drift movie clips?
Guess what they are using.
Torsen baby..

(I just have LSD & turbo envy)

 

lol...amen bratha

 

Viscous and clutch are about equal in my book. If I had to choose I would go with viscous. So you have to mantain them, well, what is some silicon fluid change every once in a while.

You still have to change the gear oil in a torsen unit. Also, I have NEVER seen a Viscous or Clutch unit look like this....

Yes, that is a quafe unit stripped, and broken, as it was pulled out of my '71 datsun 510. 224hp/203ftlb n/a 4cyl. Swapped in an OEM Subaru unit and never had a problem after.

 

A clutch lsd is actually a good lsd the only downside is that the clutch packs tend to wear out.
Torsen is used in the s5 and s6 and they are good as well... there are pros and cons to both honestly.

 

I run a Quaife ATB and that damage is not road racing damage, ( which is what the ATB is desinged for) and if it is, then you must have a prostetic feet and hands to do that kind of damage.. how old was it? I run an ATB through a 300hp+/280 tq FWD car for road, solo I racing and daily driver.. mine looks like it should with 3 years of use..

 

i'd go for clutch. most torsion diffs can't handle big power.

 

"i'd go for clutch. most torsion diffs can't handle big power."

Have you seen the Guru Motorsports unit? I don't think that bad boy would fail no matter what you could throw at it. I have tried again and again to email them and haven't ever recieved a response so I have not learned specifically how much it can handle though.

Have you ever talked to them personally? I see you are in OZ and I wanted to ask them about their lightweight rotor kit.

 

I am sorry, but I guess you were there for the destruction of this LSD. Because from what you say, it didn't happen. During an open track event, I clipped a rumble strip, which lifted the left rear tire off the ground. sending the tire spinning, As I was exiting the turn near WOT, I was sending alot of power for a 1947lb car to the rear tires. When the tire came down, the unit did it's job, and locked the rear axle. The damn near instant change in torque bias sent parts flying.

Yes it was a quafe unit, yes it was done road racing, and yes quafe kept their word and replaced it. Because I didn't want another one going south on me during an event, or just putting around on the streets I sold it, and went with a scooby unit.

I am sure I could scan the letter from Quafe, but frankly I don't think I need to jerk you off about this. You love your quafe, that's great, I didn't love what mine did to my rear end. This thread was posted to ask what people thought about the different types of LSD's, and I posted my thought, and pics to back it up. Take it for what it is.

Let it go

 

I understand how a clutch and kinda how a torsen LSD works but could anyone explain how a Viscous type works, torsen also. Or maybe a site that would explain it.

Thanks

I like the torsen... Sounds really bad when it kicks in though, like you broke something...

 

It uses viscosity (sp?) ... just noticed Corprin got a link... hehe

 

what has to be done to fit a torsen from a FD into a FC?

 

What would be the best diff for someone with a well tuned NA that wants to road race on a budget.

 

so what are the drawbacks of a viscous lsd?

 

it has high power loss.

Hi Weird they did not reply.
I help them out and normally they are really good at there e-mails. try rohan@gurumotorsports.com

Try again, or if in Texas drop in to Ari's he has several I think and Bill Cardell with the MX5's also has them, the MX5 ones bolt straight into a Series 2 (non turbo) I believe.

They have never had one fail and offer a 100% refund/replacement if they do due to this record. Made from a single piece of billet, a real piece of art.

 

Yeh, I do too. :|
