911 and Porsche world did a test once. Turns out that most of the time they (testers) were faster with a tip. A tip acceleration is alwasy the same. With a manual there was up to 0.7 seconds between the fastest and the slowest time. They did not get to the Porsche claimed time.
But still happy driving a manual

yah....your impression may be true as far as many people cant launch as well as a tip..but the fact remains that Porsche claims a 4.8sec 0-100km in a manual vs tip- 5.3 that tells you that you could take advantage of the phenomenal grip available due to having the engine at the rear...by launching a bit more harder.However tips shift gears faster than most people can esp in sport mode...

ok i get da picture...but what if i fix a torque converter that will make the tip start from 2500 rpm will that make it fast as da manual ? and would that effect my 997s warranty? If it wont thats the first thing ill be doing to my 997s!

I would suggest, you hold the pedal to the floor in Neutral, (you'll get a max of 4K rpm or so), then pull the stick into Drive and see how well you launch. I imagine Porsche have tested and designed tip to take this sort of traetment, hence they wouldn't have put a RPM limiter which only acts when the car is in Neutral. JZ

I would recommend doing that right near the dealership so you'll be able to push the car to the service department right after that.

Fair enough, but thats what the BMW lauch control basically does. Hold the revs at the maximum permitted RPM for a start, then opens the clutch.
I don't imagine Porsche have ignored the possibility of Customers doing this. Otherwise, why would they set an RPM limit on the throttle when the car is in Neutral??????
You'll only know if you try (preferably with someone elses car)

Ha...ha..ha I doubt anyone would take a chance on a transmission replacement...a clutch is a lot easier and cheaper to replace!

I guess they have a rev limiter to keep you from overrevving the engine. There are a lot of things that you can do to destroy a car that the manufacturers haven't mechanically tried to prevent. Just because you can do something to your car, doesn't mean it's okay to do it. Ask the local Porsche service manager his opinion. Do it in person so you can see the look on his face.

In fairness, I think thats completely wrong. If it was true, howcome the manual has no such restriction.JZ

I've never pondered why manufactures today limit the free-rev of the motor whilst in neutral, but it's likely an attempt to at least LIMIT the amount of potential abuse aforementioned mush-twixt-the-ears teenagers can unleash dropping their dad's Porsche into drive with their foot flooring the gas pedal. I would guess that at redline, such a move would be catastrophic. At 4,000 rpm, Porsche probably determined that the tranny might "survive". BUT, I assure you, not for long, not repeatedly.

In any event, the natural reaction would be to panic and cram the car back into drive, without thinking to lift-off the gas pedal. That 4,000 rpm neutral limit is simply a safety-net for all sorts of potential disasters relating to the fragility inherant in automatic trannies.
