Ok guys, I went to 100 mph for the "team" today (a big deal in Los Angeles, I've been told a cop on a bad donut could put you in jail for this).

Starting in 5th or 6th gear at around low/mid 2000 rpm in Sport mode, I went pedal to the metal (and held on for dear life). I saw 17 psi (1.17 bar) several times, each lasting no more than 1 second. Current temp is 4 degrees Celsius.
