Dave -- You're describing the standard "brake torque" or "brake boost" technique. It definitely puts more stress on the torque converter (and that is the technique the car magazines use to test the automatics). For the 996tt, the 0-60mph times were always a few tenths slower than for the 6-sp manual, but for the 997tt they are a few tenths faster.

slant911 is infamous around these parts
i was wondering if tip and tip s is the same thing
I believe they are one in the same. From what I have gathered Tiptronic S is the "official" factory name while as common practice people just say TIP.

If you just mash the accelerator on the tip S the lack of turbo boost will give you a shocking acceleration time. Do not expect much better than a 0-60mph time of around 5.8sec (per GPS Performance Box) on a bog standard tip TT... that is SSSLLLLOOOOWWWW.

Ask me how I know.

You need to put some stress on the old torque converter to get anything better or near the factory quoted figures.

what ??

0-60mph = 5.8 sorry but no way, that means that de 0-100km/h is around 6sec and that is impossible !

Unfortunately that is the case. Did 4 runs on a 996tt tip with no left foot braking, and runs were between 6.1 seconds and 5.8 seconds for the 0-60mph, all taken off a Performance Box.

Definitely a result of turbo lag. I am trying to convince a friend to lend me his TT tip for another test just to confirm if the test car was stuffed. My standard 993 Carrera 2 manual did the 0-60mph in 5.7 seconds (needed to dump the clutch to get that figure). Go figure. Pretty sad huh. Anyway, 0-60mph times are pretty redundant in the real world.

Just wondering if this is safe and okay to do, and if so, does this provide better acceleration times, to that of a manual gearbox launch? Thanks
I refer this technique as Power Launch; I believe some magazines also call it the same. I don't do it often but that 2-3k rpm really spooled up the turbo boost and my PS2 (almost new) spun quite crazy. For myself, the different between stardard launch and power launch was about .5 second. I have heard that people with big brakes could spool up close to the redline, and the car really jumps when launch.
