With that being said, I think that it's incredible that guys are throwing up the kind of times that they are in these cars.

It seems that our friends in Stuttgart have done everything possible to keep us from ripping low ETs in these cars:super short 1st gear, AWD that's next to impossible to launch, six speed transmission that requires you to fully disengage the throttle at least 3 times on your way to the finish line, turbos that can't be spooled on the pre-launch, super tight suspension that gives almost no weight transfer for launches, big brakes that require big wheels and tires, I could go on...feel free to add to the list.

With that being said, how cool is it to have a car that runs like a bat out of hell in the 1/4, eats everything up on a roadcourse and then drives like a mild mannered every day car around town.

With some of the trap speeds I've seen on these cars, if you fitted a modded 996TT with a Detroit locker rear end and torque converter, a 3-speed power-glide transmission, 16" wheels with ET Drag tires, a 2-step turbo system to deliver max boost on take off, line-lock, a trans-brake and a super soft suspension for max weight transfer I think we would see 8 second passes on a routine basis. But then again, It wouldn't be a Porsche that has all of the traits that we have come to know and love

 

This has always been my point of these super modded super high HP TT's whats the point if you want to drag race get a viper or a Z06 and save your $$$. The 996 finest point is when it is rolling already like any other TC car.!

 

Hard to launch because too much throttle=severe wheel hop and too little throttle=bogging.

AWD is not good for drag racing in any car. That's why all the really fast cars are RWD. You want weight transfer in a RWD car so all the weight can squat down over the rear wheels and launch you like you were shot out of a gun, here's an example:

You're not going to make an AWD 996 lift the front wheels off of the ground like that.

 

It's another reason you wont see AWD cars getting 1.3 - 1.5 60' times

 

Hmm, sounds like a new project for you!

 

and here is what in in-car 7second ride looks like from inside.....my poor camera...

Hey Joe,
Would'nt it be nice to launch our turbos with 32psi on the transbrake?
BTW...You did mean to write '2-speed power glide' and not '3speed power glide' ??

 

I think a lot of other 996TT drivers will agree that there's a fine line between the perfect launch and wheel hop or a bogged launch. I have talked to a buddy with a modded EVO 9. He launches at 6500 rpms off of the 2-step, that enables him to be at max boost on launch. If I launch my 996 at anything above 3300, it starts to wheel hop.

 

Yes, it creates a very hard to get rid of wheel hop.

 

Your S4 didn't have the vast variable RWD bias that the 911 turbo has, though. Keep in mind that our viscous unit can transfer anywhere from 5% front to 95% rear all the way to 40% front to 60% rear (or anywhere in between). Thus, when you launch, the rears break loose while the power begins to transfer to the front. Having a static 50/50% or 40/60% split would be a lot more easier to deal with. My previous 3000GT VR-4 had a near static 40/60 split and I could pull 1.69 60ft times on the stock tires. Launching the 911 turbo is NOTHING like launching that car based on the AWD setup alone...

 

Another thing that makes it difficult is the fact that our PSM is never really off. When it detects wheelspin, it takes power away (or applies the brakes) to the spinning wheel(s).

 

You can pull the MAF, but you lose your ABS also. Maybe some of the tuners can speak to this.

 

I am curious if the GT2 can have better trap time with the same mods, weight and driver.

 

Excuse me. I believe your information is not correct.

 

Read Motor Trend's latest issue titled 911 "something" does a great job of answering your question.

 

Why pull the MAF, there is a larger MAF available and it works rather well.
