Anyone want to comment on the best way to launch the TTQ for fastest times?
What rpm? Dump the clutch? I'm a little reluctant to abuse the drive train not knowing the effect on the Haldex system, so I have fallen into the habit of babying it off the line and then punching it as soon as it's rolling. I know I'm losing at least a second right there. Any Comments from you racers?<p><a href="mailto:emorawski@email.com"><img src="http://pictureposter.audiworld.com/AudiWorldPics/2000/EdTT1.jpg" border="0" alt="180Q APR Chip"></a>

Getting more air into the TT. Some observations...
Read an article on the Viper ACR and the reviewer commented that Dodge picked up 10 HP by installing a K&N filter and SMOOTH air intake hoses! So I got down and looked carefully at the TT's intake system. You guys ever notice that the headlight washer motor blocks the left grille air intake? I would guess that this alone blocks 50% of the air intake area. I also noticed on mine that the fit around the internal pieces forming the intake was very poor and left wide gaps allowing air to pass through the rear instead of into the intake itself.
I'm sure it doesn't make much difference on the street but it looks to me that one could pick up some power right there but cleaning up the whole instake area.
The whole idea of bigger intercoolers begins to make sense but some modifications are going to be necessary to funnel the air correctly.<p><a href="mailto:emorawski@email.com"><img src="http://pictureposter.audiworld.com/AudiWorldPics/2000/EdTT1.jpg" border="0" alt="180Q APR Chip"></a>

Drive it like you stole it, or are a magazine test driver...
Probably 6500 and side stepping the clutch would give (one) maximum launch. Marius is right that the clutch is the weakest link. I'd suggest that that is done on purpose to protect the remainder of the driveline (quattro). With FWD, tire traction limits driveline abuse, as it does on most 2 wheel drive production cars. Obviously 4 225 size tires can put down lots of torque.
It's sometimes difficult to duplicate magazine test times due to abusive launch techniques they use. Remember it's not their car, and the manufacturer wants the very best times to be published. The mag guys try many techniques that we might not want to subject our TT to. Rarely have I read where the mag admitted they got the great "0 to" times with a redline sidestep of the clutch.
If I recall, when the early 90's Mitsubishi 3000 GT (300 hp, allwheel drive, etc.) was tested it was very fast, but clutch life was 1-2 bonzai starts, at least without letting the clutch cool an hour or so between runs. Magazines wrote about this, which isn't usual. If you ever meet one at a stoplight, you probably won't get him to do a max start. Same for AWD Porsche. I suspect the Porsche clutch, etc. would take the loads, but most of the owners wouldn't be willing to test the system.
Notice Car & Driver's "street start" 5-60 times along with 0-60, etc. times. Often high-perf automatic trans vehicles have almost identical 0-60 and 5-60 times, while higher powered manuals vary considerably. Starting technique? Probably.
It would be interesting to know what type of abuse the factory used to test the TTQ driveline.
I'm sure they know how many redline/sidestep starts a TTQ will survive. Would they tell us?
I wouldn't if I were Audi.

A 3k drop seems to do the trick for me for spirited around town 225C driving
Feels fine, easy as pie, doesn't give a noticeable front wheel slip / power shift to the rear at take off, & starts you off in the torque plateau. I find it very helpful for making the left turn across traffic as the light turns green - when the wait for the turbo to spool up can otherwise seem endless. No need to baby your baby all the time - give it a whirl!<p><img src="http://utenti.tripod.it/~the_simpsons_family/bart/bart55.gif" border="0">

Yes, but watch for the pedal trying to catch your ankle bone...
FWIW is "dropping" the clutch a Brit-ism?
Maybe it comes from what may happen if one "un-foots" enough times at redline.
"un-foot" is a great term! Made my day. Thanks.
