Open diff to LSD
Discussion
Even with considerate running-in on the new engine I am finding the rears now spin up with great ease. Squirting the gas in second provokes some lurid moments
Some of the wheel spin is probably due to the old Pilot Sports at the back.
Anybody got real experience of going from an open diff to an LSD? (yes I know the factory says you don't need one.......)
I'm tempted by a Quaiffe ATB

I went from a standard LSD in a G96 Getrag. This gave some serious sideways action before it pulled straight. I now have a custom built G96-50(996TT)from CMS. It has an upgraded 9 plate LSD and works a treat. 85% lockup on acceleration. It pulls straight of the line. I can get off the line in 2nd with little wheelspin if I modulate the throttle.

Thanks Dave,Regards Dave
Does that LSD make the understeer worse?
Our own LuckyP runs a Quoff torque biasing diff and really rates it 
I think this is more than likely the only car currently on the scene that gets used in the way that you intend to use yours Rusti and so P's input may be of particular advantage to you, he will be along shortly no doubt

Yip, have driven open diff and then Quaife ATB back to back.
I was getting 'spinage' of the inside wheel on early throttle applications - normally on dirty airfields.
With the ATB, there is nothing but traction, and then when you do overstep the mark, it powers up the outside wheel and puts you into oversteer drift.
Another benefit is the rear axle doesn't wanna lock up so easily on badly h&t down shifts.
Thoroughly recommended

Ditto what lucky says.
I still remember the panicked cries of my passenger when staring at a hedge going sideways whilst thinking I really should get a LSD fitted... I was 'lucky' that day!
Went and had a Quaife LSD fitted asap, worked well, able to get the power down just as lucky says...
Best idea, rip out the box, and take it to Quaife (or other diff manu') yourself, but do try and refill the box before reinstalling it as it's a right pain usually with where the chassis bars run...
