Default LSD . how do you know ?

How can you tell if a Honda/Acura is LSD equipped. Is there a way to tell by looking somewhere in/on/under (etc) the car?

I'm wondering how you can tell , other then just through word of mouth.

-thank you for input.

Well, you can look at the diff if the axles are out of it. But just looking at the car, no. The only thing close I can think of is try doing a small burn out and see if you leave two patches instead of one.

Burnout? Blah! bad on the tranny and tires.

Take it to an intersection and make a turn, be part throttle while proceeding threw the intersection and hold it at around 4-5k, when you hit the turn STOMP on it when you enter the turn.

You will DEFINETLY KNOW YO HAVE AN LSD THEN!!

hahahahhahah

Can you tell ,other than the driveability of it?

axles seems to be only visible check?

i'm talking about if you were to check out a car at , ummm , a car show and the owner was not present and the cars hood was popped and you were wondering if the vehicle was LSD. (sorry, best ex. i could come up with..)

Ok, sure... That's if you've driven both and no what they both feel like. If you don't, then how is he to tell? Burnout, small one will not hurt anything. Other than that, get the car up in the air, turn the wheel one way, the other wheel should go in the opposite direction.

Just looking at it, no... Well, sorta no. But not 100%. The trans for example could have JH4 LSD stamped on it, but be an open diff.

ok, input is great.

the reason for asking question is a friend is looking to purchase a eg with b18c1 swap and sup. it has lsd also. friend making purchase is not sure if the seller is telling the truth due to not having much knowledge on the car and the seller bought the car as is from somone who swapped it all.

so , thats why i am asking if there was any other way to telll.....

what about the axles? and if u put the car on a lift and spun the right wheel clockwise the left wheel should spin counterclockwise?

Dave,

I guess your right. But of course, if you are in the powerrange, and slam the gas all the way and hit peak torque and HP, you'd definetly feel and know. a car that isn't equipped with LSd would have one wheel spinng hardcore.

It should, your right but it's not always the case. Easiest way for him to tell is a small spin of the tires on a launch. That would be the quickest easiest way for his friend to find out.

put the car on jackstands, place it in first gear, then spin one front wheel, if it's lsd equipped the other wheel should spin in the opposite direction

Disagree with that.
A few tests to support my disagreement.

1) A mates JDM SiR DC2, jacked up in the middle (both wheels off the ground) OUT of gear, both wheels spin foward, also the same in gear, just slighty more difficlut.
The rear windscreen had DOHC VTEC LSD printed in the origional print, very faded and worn, so obviously there since factory. Also stamped on box.
At the same time we also had a SIR DC2 that we knew wasnt LSD (because of drifeshaft removal etc) and in the air, they spin opposite directions in gear.

And of course, my ITR was there. In gear mine go opposites too. And we all know ITR's have LSD

I think there are just too many different styles of OEM LSD's for Hondas to have a definate simple test.

Its weird, my 96 B18CR like that too..geared or not it spins foward on both wheels. I was thinking if the seller BSed me on the day of purchase until i see track and test it out. not much feeling but definately there is a LSD.

It sounds lame but if someone never 'feels' a LSD, there aint much can do on 'typing', do a burn out might did the job but i will say some visual/mechanical inspection is more pratical.

This is the easiest way to do it.

Hey j00 and Dave_B too, that's incorrect info.

With an Open Diff and Torsen/ITR LSD, put the car in gear, they'll both act the same. One wheel will turn opposite the other. The Torsen (torque-sensing) diff will only work when torqe is being applied to the wheels (typically by the motor, and with the ground giving some resistance). Without that, it'll act the same as an open diff.

With a clutch-type LSD, (Kaaz, OPM) they'll be locked together and not turn much if the car is in gear.

p.s. I tried the burnout trick, and laid down two even strips of rubber without an LSD. That's not foolproof.

Take it to an autocross
