Why VLSD Differentials Suck | Why You Should Upgrade

[@JohannesKonow]

That viscous diff simply has to be awesome, it has 42 discs. ...I mean, who wouldn't want a diff that holds the answer to the meaning of life, the universe and everything?

[@Dentt42]

Right over here, bro!

My 95 Eclipse GSX comes with a Viscous LSD its by far the best on the market

[@Typho0nify]

Fools for Elon to send his EV into space for the meaning of life and it doesn't even have a diff! When the answer is actually here in with us all along.

[@michaelbaker1796]

The whole concept of viscous diffs is that they don't use conventional liquid/gel, but instead a non-Newtonian fluid that gets THICKER (more viscous) as the temperature of it goes up (such as when 1 wheel begins to spin much faster than the other, ie a low traction situation).

[@blainechappell5383]

It's not exactly as the temperature goes up, but more when a force and shear acts upon it. The higher the temperature, the lower the viscosity and the less affect shear and pressure have on the fluid.

[@Typho0nify]

​@@blainechappell5383 You are correct to an extent. It's more that the differential doesn't have adequate cooling and high heat is the main source of failure on almost everything. Although, it seems like Nissan deliberately cost engineered it to bare minimum, as if they know people will most likely modify/or weld them as drift missiles.

[@GeloNegron]

@@Typho0nify No, lol, they cheaped out forsure but not for us to make missiles 😂 they’re borderline bankrupt so they gotta cut corners.

[@ioanbugheanu6836]

Was about to comment this. Acutely, higher temp will make the fluid more viscous, not less. It needs to act as an open diff when at normal temp.

[@GuyX2013]

I rebuilt my diff myself with the quaife over a year ago on my 370Z and damn it's perfect for the street. It's quiet and really makes those tires grip when you floor it everytime.

[@Dr_Xyzt]

Agh. It's amazing how sticky that stuff is. Helical and ratcheting type diffs for the win!

[@TheSnoddy]

Hoping you guys go over the benefits of a Salisbury (1, 1.5, 2 way) over gear driven in regards to controlling over/understeer through throttle input. I feel like there isn't anywhere near enough info distributed on this topic when discussing limited slips and locked diffs.

[@24hourgmtchannel64]

My wife's RX300 has the LS option which I'm assuming is the Toyota viscous limited slip. Seems to work very well in the snow.

[@KoreRacing]

Bought a Tomei from Z1, 1.5 Way. Its amazing for track use. A little too violent for daily use.

[@skywalk3x]

When you say "too violent" what do you mean? Can you explain because I am doing an upgrade and info on characteristics are hard to come by. Thanks

[@patsfixxin3916]

We put one in a 260 z with a 350 it has a finned cover works good so far ..thanks for the info .I've never seen the inside of one

[@JuiceDraticZ]

[@Chimera6297]

my diff only locks up... on occasion. when the rear wheels are in the air and you spin one, the other goes the opposite direction. I have an open diff, but for some reason sometimes it'll do some great 2 wheel burnouts instead of the usual one wheel peel

[@elijahkelly8431]

Mine too! It’s a base g37 journey. Confusing stuff I almost swear sometimes both spin

[@Beliefacy]

@@elijahkelly8431 that's because the g37 have a locking diff....

[@jericho86]

So a VLSD is an open diff with added resistance?

[@ioanbugheanu6836]

Can be a lot of resistance. Far as I'm aware the fluid can become extremely viscous when exposed to friction/heat from excessive differential power transfer. It's sensitive to high temperature which makes it temporarily more resistant, but it can break down over long exposure.

[@jason1440]

When it slips n heats up, it becomes more solid to lock the plates up. Non newtonian fluid.

[@skaargan]

What is the name of the fluid they use in vlsd?

[@wedepeixmen]

when it get heat, happen the oposite, it has less lock.

[@cleanwhips3469]

I NEED ONE !! can wait for the follow up videos

[@petercraig4171]

I am Peter from Jamaica and I have a 2004 350z fairlady automatic transmission car. I would love to know what diff would be suitable for the 1/4 mile. In addition do I have to upgrade the transmission and what part if any .thank you

[@lukaslenner]

Thanks for making this video now when I am shopping for one!

[@bjornironsides6474]

Any these option lead to less likelihood of losing the rear end? Or are they about the same because a powerful RWD car taking a turn with power on will most likely kick out anyway?

[@ioanbugheanu6836]

Ya got it backwards. As the goo gets hot it gets thicker. Non Newtonian fluid as several others have pointed out. Its thin under normal temp to act as an open diff. It just might not get much thicker if it's old and broken down.

[@MrAdorabao]

Will it fit my honda? #awd

[@Qkfltpdls777]

Can you use conventional GL-5 to nissan R200V (VLSD) without LSD additives? FSM says use "NISSAN Differential Oil Hypoid Super GL-5 80W90 or API GL-5 80W-90." I was wondering if I can use any GL-5 (without LS spec or LSD additives) to our R200V (VLSD)..

[@Dan-si6cv]

love the video super informative and good humour

[@망아데요]

What is different between 1.5 way and 2 way LSD?

[@funkolog]

1.5 works only half-way when braking. 2 works the same in acceleration and braking

[@TheRobphobos]

Love the vids, very much looking forward to the next one! Thanks again from the UK!

[@aqibbhatti6482]

Died watching this it was way too spot on 😂😂😂 but definitely talk about locking rates a bit confusing I’m considering 70% on a cusco unit

[@jonathannguyen9208]

LOLOLOLOLOLOLOL You took a shot at Josh!

[@adammarron3085]

My wheel locks up everytime I drive once I start it. Gotta wait till it says slip

[@z-ro34]

Don't hate on my VLSD....(says guy who might buy a new LSD this year)

[@g35tho11]

I got 06 g35 coupe 6MT ,should I buy differential fluid that says for lsd or just one that doesn’t say that ?

[@Z1Motorsports23]

The factory LSD doesn't require any special additives. You can use any GL-5 spec fluid, however we recommend Motul or Red Line.

[@BigHeadClan]

"De Gue" - Any plans at offering an aftermarket rear-diff for the Q50/60 cars? They have an electronic based system but it leaves a lot to be desired. :(

[@Z1Motorsports23]

Absolutely! Can't speak much on it at the moment, but we hope to have more information on Q50/Q60 differential upgrades soon.

[@mediawkwardy7230]

I know this was three years ago but can you put a LSD into a viscous lsd housing?

[@Z1Motorsports23]

Yes, a base non-lsd differential can be upgraded!

How do you know wich g35s or 350z came with VLSD

[@rogermartinez78]

In the Maxima you should have a W in the transmission code, I am not sure about the G35.

[@KidKallum]

Could you just put higher viscosity oil in your stock VLSD?

[@Z1Motorsports23]

You can but it wouldn't be beneficial to the performance of the LSD. The VLSD's friction plates are in a self contained unit sealed away from the differentials oil.
