As promised! Sorry for the delay, but as stated before I was on the road.


According to pg 69 of the Road & TrackMarch '05 issue,the Boxster S they testedin the 'Best All Around Sports Car'shootout posted a slalom record speed of 73.9 mph, ousting the Ferrari Enzo. On page 73, under price as tested, they listed that Boxster's options, which included: PCM, full leather, PASM, 19' wheels, Bose, multi function wheel, bi-xenon, Sport Chrono plus, and a few other minor things. BTW, the list did not include PCCB.

Anyway, I see Bose and steel rotors are used. Anybody know how much you add weight if you get the Bose and how much these rotors weigh?

Here are some additional facts:


Cayman S had PCCB, Boxster S did not


Cayman S tested in Germany with a pre-release car, Boxster S tested at Buttonwillow in CA with a normal production car.


Cayman S gearing is TALLER than Boxster S gearing in 1st and 2nd.
Cayman S 1st Gear - 3.31:1 overall ratio 12.84:1 MPH at 7200 -44
Cayman S 2nd Gear - 1.95:1 overall ratio 7.57:1 MPH at 7200 - 75

Boxster S 1st Gear - 3.67:1 overall ratio 14.20:1 MPH at 7200 - 40
Boxster S 2nd Gear - 2.55:1 overall ratio 7.93:1 MPH at 7200 - 71


So depending upon the circumstances of the slalom, it is interesting that the 73.9 mph figure of the Boxster S is over the limit for 2nd gear, however, the 71.7 mph for the Cayman S is under its max for 2nd gear and 'could' mean the Boxster S was either bumping the rev limiter or it was shifted into the next gear. The sport chrono would raise the limit to 7300 but make a sharper cut-off. Were the cars accelerated beyond this speed and then coasting through the slalom feathering the throttle or accelerated up to speed in the slalom? The test doesn't say.


Succinctly, these are magazine numbers done at different times with different drivers and different cars and as expected returned different numbers for each car. The 71.7 returned for the Cayman S is identical to what the 997 C2S performed at Buttonwillow at the same test the Boxster S was tested. I would wager that head to head the Cayman S 'should' be faster in a slalom test vs. the 997 C2S given simply the physics involved (meaning all else being equal).


So, in a nutshell, I wouldn't make too much of the Boxster S vs. Cayman S numbers in the slalom without some actual head to head testing on the same day, same driver, multiple runs, same equipment, etc. etc.


Otherwise it is 'interesting' but not necessarily 'meaningful' to any of us. [img]/fckeditor/editor/images/smiley/MWPX/tounge_smile.gif[/img]

Confused here. You numbers support the opposite of your text. If the Cayman top speed in second is 75, it is within its rpm range, and vice versa for the Boxster. I assume you have the top speed for each gear switched between the cars?

Sorry, Iwent back and corrected that, I was on the phone while typing, merely pointing out that the Cayman hadn't reached its max yet so maybe it wasn't shifted to where it could gain more speed vs. the Boxster which might have been, but again, the slalom testing procedures aren't well described to know.
