just a general question, but when i had my itr tranny/lsd installed in my dc2,
the installer told me to be cautious when roadracing etc.
that if one wheel lifter (say from hitting that bumpy inner part of the turn, u know what i mean?) that it could do damage to the diff?


how is that,
doesnt the itr lsd (is it 1 way, 2 way?), like all lsds in general, put power down to the wheel with more traction?

therefore----wouldnt the wheel on the ground get all the power, as the wheel in the air receives no power?


hope u guys understood all that, thanks

 

I've seen videos of R's nailing the lip at like 100km/h all around the track

 

yeah ditto! awesome pics etc, bumpin n jumpin...

or is the whole lifting the power'd/lsd'd wheel thing for lsd's in general (different type of lsd)

 

It really shouldn't hurt anything, however if one wheel was to come off the ground for whatever reason, you would not be able to put any power to the ground because the LSD in the Type R is a Torsen type. Basically Torsen differentials can only put move power from the slipping wheel in proportion to how much grip the slipping wheel actually has. If the slipping wheel has no traction, then no power can be put to the other wheel, as anything muliplied by 0 is still 0. A nice trick to getting your R unstuck in the snow is to go ahead and let the wheels slip and while hitting the gas, start pressing the brake. Suddenly both wheels will start turning instead of just one and you should be able to pull through whatever your stuck in, within reason of course.

...comes from a few reported instances of shattered diff's when a wheel lifts/spins/slams back down under full throttle, shocking the diff gears breaking them... rare event that I only remember seeing a few posts of... think one was here in the racing forum a long, long time ago...

 

Ok, now jack up one side of the ITR in the front and take off the wheel. Keep it on the jack. The other wheel still on, and touching the ground.

Now start the car and proceed to move. So is the power totally lost? If this is true, you will not go anywhere.

You REALLY think there will be no power going to the wheel with no traction? If that's the case, what's the difference between an LSD and an open differential?

Would you like to try this test and verify it?

0 Traction on one wheel shouldn't make a difference. Atleast when I think about it....

 

hes right. if one wheel has no traction then the other wheel wont move.
watch me do a burnout, usually only one wheel spins until the slick heats up
and stops it and then the other spins and once both heat up they both spin.
