In modern performance tuned automatic transmissions (like the AMG tuned Mercedes transmissions), there is torque converter "lockup", meaning the power loss typically associated with automatic transmissions is a thing of the past. Very fast shift speeds in these newer "slush boxes" also help a lot.

 

heh ok ........... totally not trying to discredit the 997TT lol ...... just giving credit where it's due: if you want to go round a racing circuit VERY quickly, the Z06 is a fine car indeed.

haha is that REALLY true?!?!?! wait a sec ... i thought the Z06 was a hardtop... or is it targa?

 

[quote=crosvs]Wow. That is a tremendously overweight car. Whatever happened to Porsches being light, nimble little sports cars?!

Note that the 997 TT has 15% more hp, 21% more torque (Sport Chrono) and is LIGHTER than the 996 TT. The new GT3 has 9% more hp, 5% more torque and WEIGHS MORE than its predecessor......

[quote=Bill in Atlanta] Actually the 997TT weighs a little more than the 996TT.... unfortunetly... About 150k heavier

 

the 997TT advocates should love the fact that the C06 is faster..it will simply force porsche and other manufacturers to up the ante. It's good for everyone.

 

[QUOTE=BD 997]

RHD Owners pay atleast $175k w/o options, can you imagine the following optional parts aren't standard for them ?

- Homelink
- Cruise Control
- Electronic logbook ?
- Porsche Vehicle Tracking System ?
- Rear Wiper (No Charge)

 

[quote=Bill in Atlanta]BUT, the 997 GT3 is only going to weigh a mere 30 lbs more as I remember hearing than the 996 GT3. You really cannot complain about 30 lbs which will not inhibit performance on an already light 3175 lbs (996GT3) car. With that said. The GT3 is going to be extremely fast and quite nimble. While the TT offer you all the luxuries you can get in a car, plus the blistering speed and the capabilities of AWD, if the weight is something you dont like, get a 997 GT3, or wait for the 997 GT2 to come out. Now, lets speculate. If the 997TT has 477 hp and 457 lb/ft and weighs at least 3500+ for manual and more for the tip, the new GT2 is supposed to have upwards of 520 hp (i hope more like 550 hp) and weight about only 3300 lbs like the old one. Now imagine that. Probably high 10's, at worst very low 11's running side by side with the CGT and enzo. All speculation, but it appears that we may have a 997 GT2, so well see. I hope the car does come out.

 

the ET and 0-60 are amazing, but I think we can all agree that some of that is due to the awd system. Trap speeds of 121 don't even match the SRT-10, never mind a C6 Z06.

I would like to see more tests done for this car. But, if the car traps 120-122 consistently, it will not be a match for a C6 Z06 given that both cars get full traction, in other words, from a roll.

It happened a few weeks ago. The roof panel above what seems to be the sunroof ripped away when driving down the highway. It made the car look like a targa.

 

Bingo. That's all that I was trying to say. A 1/4 mile E/T is really more about traction (actually, that first 60ft is very important).

You can, but you can't really compare the Z06 vs the 997TT in the 1/4 E/T mark. The trap speeds, yes, but the E/Ts will be affected because of traction. The AWD allows for the 997TT to cut a lower 60ft time (typically) while the Z06 really can't. Now, put some drag radials on the Z06 and watch a few run high 10s. It has the trap speed for it. Has this been done yet? I know that we have a few low 11s runs with DRs.

People keep saying "Enzo" and "Carrera GT" territory. Not exactly. Just because they run around the same E/T in the 1/4 mile, that doesn't mean that they are in the same category. 11.4 @ 121mph vs 11.4 @ 133mph is a HUGE world of difference. Both the Enzo and Carrera GT cannot come out of the hole like the 997TT. If they could hook up, they are easily 10 second cars. RWD with that much horsepower on street tires can cause massive wheel spin. Trap speed really shows the horsepower (for the most part) while your E/T is more of a function in relation to traction on the launch.

 

Right on!! Line up a 121 mph trap car (997 TT) with a 127 mph trap car (C6 Z06) from a 50-160 and watch what happens, nevermind lining it up with a CGT or an Enzo which both trap over 130.

btw, Ruiner, "Ranger" has driven his C6 Z06 to a 11.3@127 in bone stock trim on the stock runflats, and there is another guy that just posted a 10.9@130 with headers, cai, thermostat and a tune on stock tires.

 

Gotcha. I figured that the "average" is around 124-125mph traps for the new Z06... Do those figures fall into what you have seen as well? Even 121 vs 125 will show a rather large difference from a roll. Now, if MT only tested a 997TT w/o sport chrono, it will be a little bit closer, but I don't think that it will top the new Z. I'm a Porsche boy through and through, but it's hard to overlook the sheer bang for the buck that the new Z06 offers in terms of performance.

 

bottom line... ITS AMERICAN...

 

Guys this Z06 envy is getting olde....the 997TT is it's own monster.
Just chip the damn things if they are slower than the Chevy.

 

3rd gear in the z06 is supposed to be insane. Thats where the high mph trap speeds are coming from.

If we go by stats so far, it looks like the z06 nudges the 997tt in straight line, and by nurgburgring times the 997tt nudges the z06 around a track.

Cars are VERY CLOSE performance wise.

Bottom line

997TT > Z06
