Launching. .

Can you side step the clutch on a 997 Turbo and it hook and take off, without hurting anything?

Or will it hurting something or spin or whatever?

Just wondering the best way to launch on.. I know the tips you can brake torque it untill "over boost" (read that somewhere) flashes then take off..

but how about a 6speed?

thanks

Seems like a legitimate question to me. I'm wondering the same thing. I've just decided to spec the 6 sp manual in my TT, I was originally going the tip route. Launching my Boxster S without axle tramp is tricky, but it seems to work best if I run it up to 2,500 revs and release the clutch fairly quickly, but without actually side-stepping it.

I'm interested to know what techniques TT owners find best for a quick take off without cooking the clutch or otherwise punishing the driveline excessively.

the other day i was showing my friend how awsome the traction is off the line compared to the vette and i launched at about 4k rpm and dumped it...it pulls but i really felt like an *** for doing that to the clutch and everything else after..lesson learned

BTW 335 II that is a fantastic collection of cars, and thanx for posting the excellent series of photos elsewhere. Congrats on putting it together, hope you have enough time to enjoy them all! If I had the spare cash I think I'd do a Z06 as well, but since I'm only allowed one toy, the 997 TT has gotta be the choice for me...

yeah thats what I was thinking.. but i have the same feeling.. not my car so I wanted to see how many of the owners launch thiers because I would feel like an *** launching a car of such cost that wasnt mine if I felt I was "beating" on it..

the 88 turbo supra I used to drive had a t3/t4 hybrid turbo and beffy head I had to rev it to around 4 and then come off the clutch gradually but quickky (pretty much make it slip) to keep the boost up.. i was a Pain in the *** to launch..


so what yall think would be best without REALLY REALLY beating on it yet good enough to get an impressive launch..

reving it 3-4k and DUMPING it..

or around teh same RPM and coming off it a little slower?

thanks

i've always understood the technique to be revving the car, and then quickly letting the clutch out as the rpm's climb UP. From there, it's just a matter of finding the right point between bog and wheel spin.

You can side step the clutch once then call AAA.

Ditto. Clutch smell made me feel guilty and I rubbed the leather dashboard and promised never again.....

I think the better demo is a medium 1st gear launch and and agressive, WOT run in 2nd gear to the redline (Sport mode of course). That always grabs the passenger's attention.

Australian launching technique

For what it's worth, just came across the following from the January '07 edition of Australias "Motor" magazine. They were doing comparos for their Performance Car of the Year article (in which the turbo came second to the Audi RS4, but that's another story).

"The 911 Turbo, in contrast, sounds like a jet fighter cutting through the air and, behind the wheel, it's a different animal altogether - a surreal one. Being all-wheel-drive and wearing enormous 305/30ZR19 rear tyres, it has huge traction on any surface and that means plenty of revs before wincingly dumping the clutch and hoping your lunch doesn't suddenly reappear".

"Side-stepping it on the 6600 rpm redline is a little too much, while 5500 is too little and makes the turbo bog down before going beserk. But one glorious run, launched from just under 6000 rpm, finds the Turbos sweet spot. It's a sensational launch - perfect amount of wheelspin, full boost right from the get-go, another wheel chirp when second gear slams home and a scorching 3.6 sec to 100km/h (0.3 under Porsches claim). A standing quarter in 11.6 (in 32 degree celcius heat) and the kilometre in a mind-altering 21.3 immediately sets the benchmark the others will struggle to match".

The test car was a manual, and was fastest on the day. Second was a lotus Exige S, followed by the Audi RS4 then the BMW M5.
