Well, I've just pulled my LSD to bits. It's the first LSD I've ever looked at. Everything looks good and measures up nicely and it appears easy enough to tighten it up a little. But what's got me beat is how to change the power/overrun split.
Standard Porsche has much more locking on overrun than it does with power on, in order to help combat oversteer during turn in, which is induced by the motor hanging way out the back. I believe the standard lock up is 80% on overrun and as low as 20% under power. Although this can be changed to as much as 80/80.
What I want to know is how to change the split. Paul Bearman and Pete T have been good enough to send me copies of various factory manuals but the manuals don't seem to address this issue. I believe the LSD units are the same from 915 through to G50. I have tried searching various Porsche forums but haven't come up with anything.
I would like to start off with the total opposite of the Porsche split i.e. power 80% overrun 20%. (80/80 might be OK but my geriatric pitcrew are likely to revolt at having to push it around in the pits!
)
If I could figure what the mechanism is that achieves the split, I'm sure I could work out how to alter it. But I've looked at the bloody thing endlessly, tried assembling it different ways to see what happens but nothing has yet clicked in the old grey matter.
I'm sure it's dead simple, I'm just too thick to see it!
Any info much appreciated. Thanks.
