better talk to Intense about that. I recall hearing problems with their earlier LSDs, but I thought that they fixed it. It'* not their fault, though, it'* GMs initial design (or so I've heard)

That doesn't sound good. Hope everything is fine with your diff. Maybe i was just a fluke, try it again.

I would take it easy for a day or two till you talk to Intense about the issue. The only person I've heard have any trouble with the gen3 LSD was Boosty & car trouble follows him like the police follow Haro.

Ed..ya cut me deep buddy... right in the ignition key...

Bob.. give the guys a call. Find out what it should and shouldn't do.

An LSD for our FWD cars like a stock Differential is an open design. One wheel must be able to spin freely of the other or you wouldn't be able to take turns (where one tire spins faster/slower than the other).

Because it is an open design there is always the potential for one wheel to spin in a traction loss scenario. Whether this is due to a tire having more or less air in it than the other or less tread or one wheel is more in a burnout box than the other or one tire has a little slick liquid on it or whatever. Our LSD uses clutches to make it less likely that this will happen as the clutches help balance the power 50/50 to the wheels and also makes it less harmful to produce a 1 wheel burnout by having roller bearings around the pinion shaft so that it doesnt seize on you.

Bottom line, should I be worried about this? Should I try to "repeat" it and see if it still happens?

My interruption… Even with the Intense LSD it is still possible and not unheard to spin one tire on occasion. But in the case of spinning one tire it is much safer if it does happen with the LSD over the stock diff.

I still say give Intense a call and ask your question flat out.

Sorry Bill I wasn't trying to stab down to the VATS chip just merly poke fun

There'* a technique I use at the dragstrip to make sure I get both going in the burnout box. I shared this with sonoma_zr2 and 2000Silverbullet at WCBF, and it worked wonders for both of them.

When you start your burnout (at the track or elsewhere), work the steery-wheel back and forth 5-10 degrees a few times just as the tires break loose. This allows the diff to evenly engage each side.

Wtih this technique, I've NEVER had a one-wheel wonder on either car. If you watch my WCBF in-car track vids, you can clearly see how I do it, and how much I steer it back and forth.

I wouldn't worry about it.
It'* happened to me also when one wheel is on a slippery surface and the other is not. Once that one wheel gets spinning, it'* near impossible for the clutches to grab.
I know you would think that this is why you get an lsd but I suppose, by design they can't be locked that tight that they don't allow limited slip for turns or you would get a ratcheting vibration in turns. My other three rwd vehicles have limited slip diffs and this has also happened on occasion with then too but not as much because they have solid axles. It must be an anomoly with fwd because as Bill has said you can avoid it by turning the steering wheel left and right slightly while burning out to ensure both will spin equally.
Notice on non lsd cars that if you don't keep the wheels perfectly straight, that is, turned left or right, without see-sawing, you will promote one wheel burnouts.

I guess it is possible that since the road had a bit of a crown to it (nothnig nuts, but maybe a few inches over the width of the car) that more weight was on the passenger wheel and it didn't spin as easily, and once all that torque was delivered so quickly the left one went nuts and the right couldn't keep up. The car was in D with TCS off, WSS still connected, NO preload.
