Does anyone know the true function of LSD(not the drug) in a fwd vehicle in laymens terms and would a 5AT benefit from it??

 

For example, one wheel is off the ground and the wheel in contact with the ground is stationary due to lack of power, while the other wheel spins freely. A limited slip dif. transfers the available power to the stationary wheel to aid in forward movement.

 

This helps powerful cars by limiting wheel spin in a high torque situation.

 

would it help in limiting torque steer?

 

Yea, think about it, when one wheel is spinning out it transfers power to the other wheel to balance it out, helping keep the car in a strait line

 

thanks for the info. I'm curious as to why this wouldn't be a good mod in a high powered FWD car. It seems like the FI guys wold benefit from LSD tremendously.

 

Surely not while they're driving!

 

Well just the work involved in converting a car that dosnt have it, and swaping it out for a LSD is an amazing amount of work on modern cars. Not just a simple mod

 

Which is why the 6MT is the way to go!

 

+1 yessssirrrrrr

 

That's why I got the 6spd. I knew that it had things that the 5at didn't. Including a LSD. A FWD car with this much power without a LSD is silly IMO.

It would be cheaper to do a auto to manual swap if you really want the LSD.

 

Even with limited slip, the 6MT (TL-S especially) still has crazy torque steer.

 

I have a base 06 6MT and its my first mid powered vehicle and it has crazy torque steer.
when taking a right at a light, it can get pretty squirrelly pretty quick when getting on it.
I wonder what it looks like from behind.....

 

Ask one of the 5AT guys

 

lol, taking a stab at the slower 5AT guys?

It must look pretty crazy, everyones thinking "that guy can't drive!!!"
The only advice I have received is to grip the steering wheel and hold on!

 

for grins n giggles im gona shove an LSD into my 06 auto and see what happens

 

That is true for a clutch type diff but with a torsen type(which is what the 6mt has) if one side has one wheel in the air it will act like an open differential and not transmit any power to the stationary wheel. The "freewheeling" side must encounter some resistance(traction) in order to transmit power to the stationary wheel. I really had a hard time "wrapping" my mind around the mechanical aspect of operation but this article made it happen for me.

It amazes me how many comment that our cars have "crazy" torque steer. My last two cars that had 100hp less were much worse than my TL. The only time my TL has been "crazy" was when my alignment was way off from hitting a pot hole.

 

I came from a 2002 Dodge Ram 1500. 6 cylinder. 5MT
the TL is a decent mid-powered FWD vehicle that I'm not used to yet.
coming from a rwd low powered vehicle, the torque steer is pretty scary.

 

My thoughts exactly.

 

I am guessing you are referring to gassin' it around a corner? I concede that the torsen diff does make it feel squirrely but as far as straight line acceleration, my TL doesn't jerk the steering from one side to the other(which is what I think of as torque steer) like a vehicle with an open diff.

 

Thanks for the clarification.
Straight line acceleration, I don't feel the pull to either the left or right unless I'm merging into another lane and feel the lane reflectors (is that the correct term for those).

Taking a right at a light is where it gets pretty scary. I've only done it a couple of times, and its just the fact that the vehicle is new and I need to learn how much gas to give it in the turn.

 

What amazes you? What your other cars did is irrelevant. The TL does have torque steer issues, even with the LSD. It's a fact.

Try hitting the throttle coming out of a sharp corner in 2nd gear, and you'll discover how bad the torque steer is.

 

Any time a corner is involved(one wheel turning faster than the other) and the accelerator is used it is going to be scary. It's the torsen...a blessing...and a curse. I don't track my car so corners are no biggie. If I WAS to take my car to a track, it would be a dragstrip

 

You don't need to track the car to discover the torque steer. Ever go for a spirited drive in the twisities on a weekend? I do all the time...and when the car is pushed...that's when the TS rears it's ugly head. Hell, even when driving in a straight line on pavement that has slight ruts...hammer the throttle, the car will pull violently to one side or the other. The LSD lessens it somewhat, but it is definitely a handling liability. The facts is it's one of the shortfalls of sending a lot of power through the front wheels....can't be helped...

 

Mine doesn't do this. Maybe it's because the type-S has more power and it is more noticeable.

Right after I bought the car. On the way home from the dealership actually. I was behind a slow car on the highway. I accelerated to pass and to get in the other lane at the same time and the torque steer caught me soooo off guard. I damn near rear ended that person because even though my wheel was turned, as soon as I dropped the hammer the car straightened itself out. That was scary and cool at the same time cause I realized this car had more power than I was used to and that made me happy.

 

I never said the TS wasn't there....I just commented on how some say how bad it is. It isn't really that bad when you compare it to other FWD vehicles. Now for those coming from RWD, yeah it is a rude awaking having the wheel jerk to one side. I have had FWD for many years, so I have gotten quite used to it.

 

Oh, but I am used to it now. Just have to beast the steering wheel in the direction you want to go.

At Mjakaz06TL, is it even possible to put our diff into a 5at? I didn't think it was.

 

I really prefer the FWD. Never use the brakes on a turn and you're gold. Drop a gear and WOT all the way through the turn and you will get really good traction. Do this in a RWD and your ass will do a 180 off the road. I know because that happened to me.

 

I have a base TL and when merging and hit the bumbs (lane reflectors) she pulls hard to one side.
I just have to learn and adapt to the road and know when to grab the wheel.

 

For sure. Around corners it's made worse because of the torsen(the curse part) but to me it's a small sacrifice for the straight line reduced torque steer and traction increase(the blessing).
I certainly agree that there will be problems associated in making decent power in a fwd chassis. The TL(6mt) "rearing it's ugly head" around corners, however, owes a lot to the diff. I have a Pilot(240hp) and an Odyssey(255hp) that do not exhibit the the same problem when turning. They simply "roast down" the inside tire. Take off from a stoplight at WOT(don't even ask!) and you had better have a grip on that wheel

 

Me too!

 

Thanks Jpoole for all of your insight.

Helps me to understand my car a little more.

 

Houston huh? I bet you do a lot of that merging with all that construction always goin' on there

 

Velcome

 

haha you're right about that!
with all the construction and the current rain makes one dirty TL.
