Is holding the footbrake while revving the engine to a certain point - the best way to do it ? What revs are you releasing at ? What is the best time for 0-62 mph which you have recorded ?

 

i guess we 'newbs' must help each other out...i found an interesting article that examines both automatic and standard launch techniques...

p.s: Automatics aren't supposed to be used as racecars!..

 

Thanks, thats a good read.

 

Full brakes, then full gas, release the brakes and let it go. It doesn't work with the manual transmission. This is the reason why the Tip is faster than the manual in 0-60mph.

For rolling start drag races (60mph-100mph, 50mph-100mph, 50mph-150mph, etc), the best take off technique is to lightly hit the brakes, then lightly hit the gas (it fools e-gas), hit the brakes harder compesating with gas not to lose speed, until you're at full gas, release the brakes and bang...

 

Yea the tip allows the boost to rise before launch, can't do it with 6speed

I think that would affect the car a lot

 

Excuse me guys...if you step both on the gas and brake, and you release the brake quickly...wouldn't the car start to slip hardly??
I know it's AWD but...seems to much...

 

Nope, I tried it a few times ... the traction is amazing!

 

WOW incredible indeed!
I never thought it could have been possible even from a Porsche...thank you very much for your answer Rami

Probably the car with Tip. can distribute the Newton/meters in a different way from the 6speed one...

The key is putting the car in Neutral, it really does allow you to apply more brake pressure and build boost before take off.

 

You mean put the car in Drive, right? Putting it in neutral would not require any braking, it would seem.

 

Take the PSM off. Start with the car in Neutral and foot on the brake pedal as hard as you can, give the car a quick rev. (in neutral) and then put the car in (man. mode) 1 st gear, you will actually feel the brake pedal go further down applying more brake pressure. This allows you to stall the car up with the throttle. Stall it up until you feel it wanting to creep then let the foot brake go and smash the gas. Boom your off. Now I have a 02 TT with over 530 AWHP and it works for me. I am "assuming" it will work on the 997's. Good luck. I found without puting it in neutal and giving it a quick rev. I didn't have enough break pressure to apply the gas to stall the car up.

 

I still don't see what effect, if any, putting the car first in neutral has to the braking ability of the car. I would think just putting enough brake pressure and giving it gas(in Drive) to a certain desired RPM and then simultaneously releasing the brake, and applying full gas would have the same effect.

 

if a car has power brakes, i believe that putting it in neutral and then stepping on the brake tricks the torque converter and thus locks the brakes significantly 'tighter' then by simply pressing the brake in drive...i may be wrong but this is what i was told and it seems somewhat plausible...
