Launch control with manual trans???

I have a 08 997 TT this is my first Porsche ever so please forgive me if this is a stupid question.. I do have the crono package, as I've been researching only found out its only for the tiptronic ,so that made me confused as to if you can use launch control on a manual..

The only computer controlled launch, that I am aware, of a manual transmission is with a GT2.

Correct only the GT2 or GT2RS (and then the new gen TT's)

thanks for clearing that up .. So... well I guess would be the next question is in a race from a stop how would you optimize takeoff without launch control??? Im in alaska so I have not yet had time to properly learn my car,as the roads arent up to par yet..Do I drop the clutch on a rev or do I take off hard on the throttle after the clutch has been engaged??.. I dont want to ruin my clutch like all these guys around here in their wrx dropping the clutch on damn near full boost..

I am also wondering how they get thier 3.7 0-60 time on a turbo w/out launch control as Im sure most of you know on the porsches I found out 1st gear is really short..Then I thought (and this is me pulling an Idea out of my *** lol) are they doing a 2nd gear launch while dropping the clutch on boost.. Idk..Im sorry if this is a stupid ?

You can't build any real boost without putting load on the engine, or having a computerized launch program. Even with Launch Assist, the GT2/GT2RS do not launch with full boost.

Every time you drop the clutch, drop $10 in a coffee can for a new clutch. If you drop the clutch, you put wear on it. If you slip the clutch, you put wear on it.

This is a great post and would love to hear other 6speeders on how they launch their cars properly and without excessive damage. It would be nice to see a POV video with someone doing a nice launch. I try to launch around 3-4k RPM by slipping the clutch (vs dumping) and I often experience a bit of hesistation / bog right after the launch.

Anyone knows if this feature could be added to 997.1's? Would be very nice if we could launch with boost like the tip guys ..

9/10 times you will be quicker than your opponent (assuming theyre driving a manual as well), if you do a fairly SOFT launch.

Ive noticed my car almost slingshots off the line if i launch at 2300-2500.
The car gets off the line with MINIMAL slippage, and because of the exhaust and LWFW, it is able to get on boost within 10 feet.

If you can figure out the best RPM to launch, you can ask a tuner to program in a 2 step rev limiter. You won't launch with boost, but it takes much of the human error away.

the RPM when you launch isnt as important as the amount of clutch slip you apply.
if you dump the clutch the car will either bog or spin. slipping is the trick.

^modified/non modified really wont make that much of a difference.
our cars (stock or tuned) run STOCK boost in first gear.

so weather you have a stock 997tt or a 700hp vtg monster, 1st gear will see the same boost.
