Hi all, prospective turbo Porsche owner here for next spring. Doing my research now.

Have to admit, I'm pretty infatuated with the sub 3 second 0-60 times laid down by the 997.2 PDK turbos using launch control. I'm also intrigued by the history of the Mezger motor on the 997.1 but generally speaking its seems like the lack of PDK and launch control holds it back a measurable amount on the acceleration from a standing start.

I'm not interested in a tiptronic transmission if I went with a 997.1 What would need to be done to a 997.1 manual trans to click off those sub 3 second 0-60 times? Is it possible?

Still looking at turbo cars also.
You can look at some ET time at DRAGTIMES.COM
Looks like 2011 Turbo S with launch control turned off is running low 11's instead of the 10.6 or 10.7
it runs with launch control on.

Still looks like heavily modded 997.1 run some geat times.

That seems to reinforce how important the launch control is. I'm sure at a drag strip with good tires and hook up a stock 997.1 is hitting 60 at close to 3 seconds. But on the street doing it consistently would be a whole different ball game, while a 997.2 with launch control would really shine.

Here's the deal,
997.1 Turbo: 480 HP; 0-60 6-speed manual: ~3.7 sec per car and driver
997.2 Turbo: 500 HP: 0-60 PDK with launch control: 2.9 sec

(people don't hang me if I'm off 5 HP or .1 sec above)

Bottom line, you're talking about roughly a 20 HP increase in the 997.2 TT. The 0-60 time difference is obviously not driven by the power difference, this is all about the PDK + launch control which results in your ability to get a 0.8 sec reduction in 0-60 times.

There is NO easy way you can match that with a 6-speed manual. This is all about launch traction and the ability to maintain boost when shifting from 1st to 2nd with the PDK and making that shift in a millisecond vs laying off the throttle, losing boost, manually shifting into 2nd and smashing the gas and rebuilding boost in the 997.1 6-speed manual.

Hope that helps

On the 2007 Car and Driver did a test at strip.Factory numbers of the 3.7 on the manual don't include rollout like at a real drag strip which are usually lower.The manual at the strip did 3.4 0-60 even thou factory claims 3.7 and like Art just said: driver,launch etc.
Nice write up on the earlier 997.1 TT by Car and Driver if you want to go thru its at:
http://www.caranddriver.com/reviews/...take-road-test
Launch control is a nice setup.When at the drags if the other driver is staged first those lights are going to come down fast if you stage 2nd you might not even get launch control set unless you stage first.

Thanks for the responses. Kind of what I figured on the newer technology being difficult to overcome for a 997.1 manual. I've drag raced manuals (domestic muscle cars) for years... fun but less consistent and at a disadvantage to the newer sequential manual gearboxes.

Here's the thing though, while the newer technology in terms of the dual clutch systems, PDK etc are fantastic when it comes to the track, drag racing and even stop and go traffic, for many of us there is nothing like the pleasure of rowing through the gears and rev matching a down shift that you get with a 6-speed manual. I personally will choose the three pedal configuration every time as long as it continues to be offered .

I guess that's my long winded way of saying that while progress will continue to happen, not every purchase decision is driven by 0-60 times and having the latest and greatest tech in the car. plus these things are blistering fast in the mid 3s regardless of which gear box you choose

you can't go wrong and good luck with you purchase decision!

The .2 turbo with launch/PDK is insane off the line!!! I had an 08 turbo and was shocked how much faster and smoother the .2 turbo was.

General Jack

I've always said the same thing. This is the first time I've seriously considered not having a true manual trans car in the garage!

General Jack

I haven't had the chance to experience it yet... but definitely looking forward to it. My last hot rod (non Porsche) ran high 10s / low 11s in the quarter mile but couldn't hook on the street. Love the fact that a 997.2 turbo would be able to do both.

My comment - once you've hit the turbos in a straight line a couple of times, it becomes a 'been there done that' type of scene. Who cares about less than a second difference? Where these cars really shine are on the twisties, not straight line drag racing. What I'd really be looking at is the long term living with a PDK vs a MT. There are suspension differences between the .1 and the .2. They both need an exhaust upgrade fro the OEM so that's out of the decision. My 2 cents...

A manual 997 TT will never get in the sub 3 second range. Even the tuner cars with 800+ hp still have very similar 0-60 times at a stock TT.. It's 60 to 140 where the power comes in. If you want to be in the sub 3 second club you have to go with the PDK..

General Jack

Yeah, I'm hearing that about the exhaust, will need to remedy that for sure.

I've had several fun cars including great handling cars such as a BMW M3 and melt your face in a straight line 700 hp 427 Camaro. I've road raced, drag raced, etc.

You make good points... But right now where I am... is wanting bragging rights of 2.xx 0-60 and 10.9xx quarter mile in a refined, sophisticated and reliable package. That brought me to the 911 Turbo! And sounds like I need to plan on a 2010+ PDK.

I believe there is an aftermarket launch control you can add. I'm not 100% but I'll take a look.

Funny how these discussions turn 180. Back a few years ago, I had a 993 carrera s tiptronic. I got so much negative criticism that I got rid of the car. Sweared I never would buy an automatic again. In my book it's a six speed, keep your PDK quick slinging shifter. I ain't dragging no one in my car anyway. It's all about style baby, old fashioned driving going thru the gears.
