Page 28, in the news section of the April 2007 issue (fugly Audi R8 thing on the cover), there's a little yellow panel entitled Porsche Power and graced by a detailed inner-workings illustration of a flat-6.

"The next-gereration Porsche 911... blah blah blah... more power etc.... said one Porsche insider. ...dual-clutch system... blah blah blah...

...but don't expect an RS or GT3 version of the new Cayman - or even a differential lock, said our source. "If the Cayman had a diff lock, it would lap the Nurburgring faster than a 911, and we must keep the performance gap between the two cars."

Ian Adcock wrote this tidbit, and of course kept his source anonymous - but the tone and phrasing sounds fairly engineer-speakish to me.

So the gap is that close!

Differential lock -- does he mean a limited-slip diff? If so, I expect a really nice unit to be available in two months (not the F-L/Stasis LSD or a Quaife).

Yes. What is limited is the freedom of the left and right wheels to spin at very different rates like they can in an ordinary open dif when one wheel is sitting on ice and the other sitting on tarmac. The dif "locks" them together to spin at or near the same rate so they both transmit torque.

OK, I better check that...

OK so the wiki authors agree with me. But I have heard that most university professors will not allow students to cite wiki as a credible source in their research papers...

Lee,

Would love to know more about the limited-slip diff. you are talking about. All in good time of course.

Thanks for sharing in advance.

if you want a REAL and GOOD LSD, paul guard makes them.
both Torsen and plate type.
why wait for PAG.
