Limited Slip Differential

Limited Slip Differential
I googled for this, but I may be handicapped. I cannot find anything about HLSD. How do I find out if I have LSD? I'm sure this has been discssed before, but yahoo searh of forums does not turn anything up, and browsing through 20 pages of posts does not show anything for this either.

1. Open your hood, look on the top right side of the engine bay and you'll see a plate with various numbers, with the VIN one of the numbers... look down to find the numbers to find the transaxle code.
2. If its RS6F51A ya have open differential. If its RS6F51H then ya have HLSD.

Here is something I found about Lance EVO, but I'm sure it applies to all of us with VLSD or HLSD.
The front differential's helical design provides it with smooth operation and superior responsiveness. Small in both size and weight, the helical unit does not require special oil or additional maintenance.
Helical-type limited-slip differentials offer several advantages over the clutch-type or viscous LSDs. Viscous limited-slip units tend to wear out after extended use, as their oil is heated and reheated until it degrades, rendering the unit ineffective. Clutch-type differentials provide good off-the-line traction, but the 50/50 stability that's beneficial in a straight line is not so desirable when a vehicle is turning. The helical-type limited slip provides better durability and performance when it's needed most: while turning. Unlike an open differential, which shifts power to the wheel with less grip, the helical LSD constantly shifts the bias toward the wheel that has more traction.
Under straight-line acceleration, power remains evenly split between the front wheels. While cornering (e.g. accelerating out of a turn), the helical LSD directs power away from the inside wheel and toward the outside wheel, allowing the driver to begin accelerating earlier and exit the turn at a higher speed, without losing traction in the process.
P.S. Thanks for the above reply Puppetmaster.

Yeah, I bought the car used, and it has AE door sill, and drilled pedals with rubber padding glued/inserted to the bottom of them. My chassis number on the inside of the engine compartment says RS6F51H, think this means its got helical LSD. However, when I am in 2nd gear, really hitting the gas, past 4k RPM the car starts pulling to one side or the other a little bit. I was under the impression that HLSD or any LSD was supposed to prevent this from happening. Also, does HLSD or any LSD help in wet weather on a car w/o traction control?

And yeah, it does help a lot then accelerating through corners in slippery conditions... you do notice it.
