No negative energy, if anything I like drag racing the 996tt as much as anyone. Which clutch is in the car determines the first part of the track as much as anything . With a stock clutch you can launch the car VERY hard, however you will be looking at replacing it very soon.
Turn the PSM off for drag racing. Check your tire pressure, make sure they're consistent across the board and drop the rears to around 30-32psi hot (you will likely need to play with this depending on the tire you have on the car). Skip the water box completely and do a quick pre-launch to shake any debris off the tires before heading up to the line. Again with AWD you want absolutely no water on the tire when you enter the tree. I would suggest starting around 4500rpm and slipping the clutch quite a ton to prevent wheel hop, if you feel the slightest hint of wheel hop ease off the gas and be ready to short shift. Depending on your powerband you will want to shift a bit before red line, when you fee the car starting to accelerate slower towards the top, make a shift into the next gear as quickly as possible, and stay in 4th through the traps.
Clutch slipping is the key to getting a good 60foot, on street tires I'd say if you can hit a 1.7-1.8 your first time our you should be very happy. On the stock clutch and tires we where able to get a 1.61 60ft launching at around 6500rpms, however if a new clutch isn't in your future I wouldn't suggest this.

I know this sounds silly but dont let off accelerator until you know you passed the end of 1/4 mile

Pull fuse B9 to completely disable PSM. Drop your tire pressures to 24psi all around to minimize hop and maximize traction. Avoid the water at all costs, and do a quick burnout to get rid of any you may have tracked into. Dump the clutch at 4k rpm and progressively get into the throttle in 1st. Then concentrate on hitting every shift - I had the most success short-shifting at 6k rpm with K16s.
With the stock clutch and ~575hp, you'll likely burn it out...

You just have to learn how to punch the hell out of them

If you really hit it perfectly I think an 11.9-12.2s are possible with good conditions in a stock car.

Don't be to concerned with your time. The trap speed tells all.
I do want to add that the place where you will gain or loose is in the shifting. When there is no load on the engine (During shifting), boost drops and has to build up again, the quicker you shift, the less boost you loose between shifts and the faster you will go. If you have a stock clutch, I would not recommend hammering off the line. Roll out like everyone says. you will loose about half a second because of it, but you will drive home at the end of the night.
Hence the reason why auto trannies are usually faster in acceleration than stickshifts in the same car.

Trap time does tell most of the story, however at the same time will very quite a few MPH from a proper traction pass, and an "easy" pass.

that is excellent on street tires. But bone stock you probably don't spin them much. I cannot get traction in the first 3 gears in cold weather and in hotter weather I can't traction in the first 2. I have PS2's.
Believe it or not, trap speed won't change much regardless of your 60ft time. Only your ET will change. I have had times that varied by a full second and my trap speed varied by half a mph.

That's an insane 60' time. If he can get down into the 1.7's he should just crack 12's stock. Not easy on street tires for sure. Practice practice practice! Find an empty lot one weekend and just launch.
What are the exact mods on this kit (OP)?
