    LSD for manual from May 2009

    ...according to the latest German Cayman price list.

    It is even not yet on Porsche Germany web site. Thanks for tip Bernd!


    Re: LSD for manual from May 2009

    UK OPCs have confirmed the same


    Re: LSD for manual from May 2009

    What did Clarkson say when he was reviewing on TopGear?!

    ...something like "Porsche didn't fit a LSD to the Cayman as otherwise it would be faster than a 911"

    Should be interesting to see how true that is.

    Re: LSD for manual from May 2009

    Very, very TRUE.

    Fact No.1

    Sport Auto tested FL Cayman S equiped with PDK, PASM, SC Plus, 19" and LSD and it achieved 1.13,9min on Hocknheim with Bridgestone RE050 N1 tires...

    ...previously tested 997.2 Carrera 4S equiped with PDK, SPAMS, SC Plus achieved the SAME 1.13,9min on Hockenheim on same Bridgestone RE050 N1...

    ...and 997.2 Carrera S equiped with PDK, SPASM, PCCB and SC Plus achieved on the Hockenheim 1.13,4min with same Bridgestones(1.13,4min is the also the same time that R8 achieved equiped with Magnetic Ride,standard brakes and standard Pirelli P Zeros).

            thanks! Is there a section on ams website where I can see and save as .pdf other cars pricelist?

    LSD also shows up on the US Cayman Order Guide.Smiley

    Re: LSD for manual from May 2009

    LSD w/ the manual tranny is good news. Too bad there appears to be no Sport PASM option for the Cayman.

    Re: LSD for manual from May 2009

    Thanks Kreso! Smiley  Currently with the 3.6 997.2  adding LSD requires 19" wheels, my German is not good, but from this Cayman price list it looks like it will be possible to spec LSD on the Cayman S with 18s,  hope I'm right. Smiley


    Re: LSD for manual from May 2009

    OPC said LSD, Manual and 18" was possible

    Re: LSD for manual from May 2009

    Thanks GR, good to know! Smiley I really like the ride on 18s, even though I'll be the first to say 19s look a lot better and I sometimes take a little heat for it.

    Is Model Year 2009 for the Boxster/Cayman going to be a short production year with 2010 builds back to the regular schedule starting this summer?

    Is LSD of any benefit to people who don't track their cars and only drive on the street and highways?

            IMHO yes. Just one other question-why is someone buying Cayman(or any sportscar) for street and highway driving only? IF you do not plan to drive it at least on mountain road(or windy road) there are much, much better choices for this usage then sportscar...

    "

    The main advantage of a limited slip differential is shown by considering the case of a standard (or "open") differential where one wheel has no contact with the ground at all. In such a case, the contacting wheel will remain stationary, and the non-contacting wheel will rotate freely—the torque transmitted will be equal at both wheels, but will not exceed the threshold of torque needed to move the vehicle, and thus the vehicle will remain stationary. In everyday use on typical roads, such a situation is very unlikely, and so a normal differential suffices. For more demanding use, such as driving in mud, off-road, or for high performance vehicles, such a state of affairs is undesirable, and the LSD can be employed to deal with it. By limiting the angular velocity difference between a pair of driven wheels, useful torque can be transmitted as long as there is some traction available on at least one of the wheels.  "

     


    Re: LSD for manual from May 2009

    I fully agree with Kreso Smiley Even if you don't track the car you will sense the advantage of the LSD (= better traction) on twisties (especially hairpins).

    Why do people buy a sports car for street or highway driving only? To have more fun of course! I think you'll agree it's more fun to drive a Boxster than a Honda Accord  on the street or highway. Smiley I'm going to take a guess, probably 80% of buyers of sports cars (Porsche, Ferrari, etc...) never track their car.

     


            


    Re: LSD for manual from May 2009

    In every day driving the LSD will also help you pull out of side roads onto a fast main road. 

    Also, I wouldn't be surprised if its 90% of owners never track their car


    Re: LSD for manual from May 2009

    Anyone here have details on performance of the 997 LSD versus the 996?  I seem to recall that the 997 (turbo) now uses an LSD that is electromagnetic based rather than viscous...right?  I assume the Cayman would use the newer technology...?

    I expect this to be tremendously superior to viscous coupling (in response time and tunability) but don't know if this has really improved performance or was mostly hype (like the VTG turbos).  Anyone have feedback on how well the new version has worked out?

    I post this here within the context of the Cayman, but of course applies to turbo as well...

    Thanks!!


    Re: LSD for manual from May 2009

    I must correct you little bit-997 Turbo AWD system called PTM use front electromagnetic differe ntial BUT, rear optional LSD is same as before.

    997 Turbo AWD PTM system was discussed on 997 Turbo board pretty much in-depth and relative end conclusion is that it do not offer any serious advantage over more agricultural AWD systems on midengine sportscar a la R8 or Gallardo. In fact 997 Turbo traction on wet road if for example inferior to those on R8. I will stop here since this is Cayman board after all.

     

    How good is Cayman S with LSD? Just look at track time on Hockenheim 1:13,9min which is the same as 997.2 Carrera 4S. Both cars testes by German Sport Auto.

     

    Cayman S 1:13,9min (PDK, LSD, PASM, 19" and SC Plus)

    997.2 Carrera 4S 1:13,9min(PDK, SPASM, PCCB and SC Plus)

    997.2 Carrera S 1:13,4min(PDK, SPASM, PCCB and SC Plus)

    Debate about what car is faster on the track like Hockenheim ends here...

    Thanks Kreso!


    Re: LSD for manual from May 2009

    Does anyone know whether LSD will be available with a 6-speed manual transmission on the Boxster S starting May, 2009?

    Yes.
