Porsche 956

Did it employ that PDK system - I think it stands for Porsche Dopple Kubblung, or something like that - where it pre-selects the next gear?

That would be Porsche Doppel Kupplung then. Has never been used in the 24 du Mans, was only used in so called 'Flugplatzrennen'. Porsche is adapting the Aud/VW DSG gearbox, and will call that the DPK again. Will be available on the 911/998

Going back to the synchro 956, I thought the reason was that you could change gear faster, as it helps the dogs engage, and puts less stress on them making it more reliable.  Plus they were planning to sell them to privateers, who would like it if they were used to less exotic machinery.

They did use it at other races, i seem to remember Derek Bell having to use it in i think the Malaysian race when they had torrential rain. On the fasted part it started changing down on it's own! Only the rev limiter saved the pistons from going into low orbit.
