Some interesting tech data on the 981 I came across that I didn't know
1) The usual coolant temperature when the engine of the Boxster (S) is at operating
temperature is 221° F (105° C); it is reduced to 185° F (85° C) during sporty driving
and in Sport/Sport Plus mode by opening (energizing) the thermostat.
2)The manual transmission can be optionally equipped with a differential lock (with PTV). The
locking value is 22% (traction) and 27% (deceleration).
[b]Can anyone elaborate on what these figures mean?[/b]
3)The transmission oil can be heated up quickly via an oil-water heat exchanger. This
reduces the viscosity and consequently the friction in the transmission, which has a
positive effect on fuel consumption. At higher transmission oil temperatures, the oil can also be cooled via the heat
exchanger. ([b]this may be old news but I had not idea the tranny had a heat exchanger on it)[/b]
4)The coolant temperature gauge in the
instrument cluster shows 194° F (90° C)
at normal operating temperatures
(185° F - 221° F/85° C - 105° C).[b]On our car it's really 200deg F.[/b]
5)The axle kinematics have been optimized to improve driving dynamics and for an
optimum camber rate and toe-in rigidity. The camber values vary for the different
variants (e.g. camber for Boxster and Boxster S – 1° 20´, PASM chassis – 1° 30´).
The kinematic toe-in adjustment is approx. 2’ per 10 mm of compression travel,
while the kinematic camber adjustment is – 15’ per 10 mm of compression travel.
[b]If I understand this correctly then, you can get -1.3 camber (F) with stock suspension and -1.5 camber with PASM.[/b]1) The coolant temperature when the engine of the Boxster (S) is at operating
temperature is 221° F; if you activate the sport or sport + mode, the temperature will drop to 185 F.
2) The PTV proves a locking differential with the manual. The
locking value is 22% (traction) and 27% (deceleration).

3) Probably old news but, at higher transmission oil temperatures, the oil can also be cooled via the heat exchanger. Had no idea that the car was equipped with a transmission cooler.
4) The coolant temp. gauge shows 194 F. when the car is operating within normal temperatures
at normal operating temperatures (185--221F)
On our car it's really 200deg F.
5) If I understand this correctly then, you can get -1.3 camber (F) with stock suspension and -1.5 camber with PASM--a significant increase over the 987.
