LSD??? No Way

[DriFt3r]

OK can any of you guys explain this to me. I thought that my 95 didnt come with lsd but everytime I do a burnout in a straight line, there are 2 equally black marks on the pavement. When I try to drift it also seems like both wheels are spinning at the same time going around a corner. But when I am at a full stop and I turn my wheel all the way to the right or left and do a burn out it only leaves one line. I've done about 20 straight line burnouts and it leaves two marks everytime. Is this suppose to happen or is there something wrong?

Thats the VLSD....i got it...same thing as you...the reason for only one mark when whipping her around is that the outside tire has more weight on it and the LSD is putting more power to it since the inside wheel doesn't have as much traction...

A VLSD IS A TYPE OF LIMITED SLIP THAT USES A VICAIOUS FLUID FOR FRICTION, THERE IS ALSO THE HELICAL TYPE AND CLUTCH PACK TYPE.

HONESTLY YOU PROBABLY HAVE THE VLSD AND IT IS WEARING DOWN, YOU CAN TELL BECAUSE YOU ARE APPLYING ABNORMAL AMOUNTS OF FORCE ON ONE TIRE AND THE LSD CAN'T HANDLE IT SO IT IS JUST SPINNING.

I thought that 95 240's didnt come with vlsd's if they didnt have Abs. How can I tell forsure if i do have a stock one or not?

if you lay 2 patches when you peel out the you do becuase there is no other way you could do that. if you lay 2 skid marks down when you do donuts (consistanly) then you have it. also if you prop up the back end and speen one wheel with yuor hand.....(someone finish this i am not totaly sure whats supposed to happen)

I've put down two patches when I've peeled out and I don't have LSD. You can look on the pumpkin to see if theres an orange sticker there for VLSD. Ifyou have the back end up and spin one wheel by hand, the other should spin in the same direction(car should be in neutral of course). Then with the car in gear, it should be harder to spin the back wheel, and the other one should spin in the opposite direction. Another way is to have someone hold one wheel and it should be very hard to turn the other wheel, but can be done with enough force(car can be in neutral or in gear).

As much as I say this over and over, you must put the car in gear with the rear end off the ground to test for it. Just like you are able to lay 2 strips down with an open diff, both wheels can turn the same direction with the car in neutral. Last time I checked both rear wheels move the same direction when you move the car so it wouldn't be so abnormal to see bnoth wheels turn the same direction no matter what kind of diff you use. By locking the driveshaft in place you will isolate movement to only the spider gears and the output shafts. Since the ring and pinion can not move, the only movement that can be made is that the other wheel will turn the opposite direction (Open diff and VLSD). The difference will be that the VLSD will have a moderate amount of resistance. An open diff will be much easier to spin the wheel when the driveshaft is locked. The resistance the VLSD puts on the diff is only in the spider gears. so isolating the movement to only the spider gears will rule out the possibility that there is enough friction in the gears to bind both wheels together when testing in neutral.

or you could just check the model number...

From: http://www.nissaninfiniticlub....umberS14: Checking for LSD using Car's Model number

Find the car's identification plate on the firewall, passenger side.

Check digit 18 in the model # (not the VIN!).

For Feb '94 - July '95: A, C, or E, = LSD

F, or "-" = NO LSD

For July '95 - July '96: A, C, or F = LSD

B, D, or "-" = NO LSD

PS, I have 1337 posts. Spells out leet

Searches do wonders!

^ Is there a code thingy like that for S13s?

edit: ahaha, wtf was i thinkin, they only had LSD's on the HICAS ones

[DriFt3r]

Thanks guys, I just went and check and I dont have Lsd because of the "-"...........btw why do I still make two black lines when I do a burnout?

[marcusx]

Thats cool... I just checked mine and I have a C.. :ylsuper

[Rockenreno]

btw why do I still make two black lines when I do a burnout?

I too have a "-" You may just be getting good traction for some reason... unless you have an aftermarket LSD (highly unlikely if you didn't put it on yourself). I don't really know much about that though.

You are most likly doing a burnout on flat even ground so both wheels have the same amount of traction so they both spin, but when you go around a corner the inside wheel spins and no power is sent to the one with more grip and the inside one just keeps spinning untill you straighten out or let off the throttle. I bet if you got halfway off the road and had one tire in dirt or gravel and one on pavement only the one in gravel would spin.
