Anyone know what setup the new 997.2 GT2RS has?

-saying that the GT2RS only runs 700Nm torque dispite it having 620PS power.

Alex

I believe it is still called 997.1 GT2RS, since it still uses the dry sump engine.

It comes with Porsche LWFW as standard, the one that has been used since the 964 days.

Thanks for your thoughts guys. That kit I linked to in my OP looks like a Sachs kit to me with a 890Nm pressure plate.

Single mass flywheel is what I am debating. Apart from the rattling on idle, does it make for a better driving experience?

I just bought the Stage II.5 Sachs kit and was wondering which set of bolts I need from the picture above (i.e. the black ones or the silver ones). I presume it's the black ones to join the pp to the flywheel, right? I'm sticking with stock flywheel.

As far as the clutch slip, 60 mph in 6th gear is about 2300 rpm? I am no expert but I think the clutch would be more likely to slip at a much higher rpm. Why? Because you are looking for the point where there is maximum torque on the clutch, causing it to slip. In our Turbo this would be above 3000 rpm, where the "power explosion" occurs. More specifically the torque plateau of our Turbo's is around 3300 rpm to 4300 rpm range (depending on which dyno but this is the general range).

In my car, I vaguely remember it was 4th gear around 3800 rpm. The needle just slips from 3800 to 4800 rpm without any speed change in the car. Anyone has anything to add to this please?

Yes that is exactly what happens with my car, at that precise rpm in 4th gear when I get on it hard. It started doing this after I upgraded the stock exhaust to the Akrapovic Evolution system and had Ian at EVOMS flash the ECU. I had to ask my friend yllwturbo what was going on and he said the clutch was slipping even though I couldn't smell any burning clutch odor. It is a very dangerous situation as there is a sudden loss in power during acceleration and it doesn't happen consistently. I am considering ordering a Sachs Performance Pro kit, part # 999764-000073.

Yes and it only get worse with time...eventually can't accelerate at all with out
constantly approaching red line at modest speeds.

Since New York has become a "1984" police state I have found any speed above 50MPH to be dangerous any way...but

I won't have a choice but to get at least a pressure plate soon.

Serpentene 07-16-2011 04:09 PM

Oh yeah one other thing you burn a lot more fuel too....

Finally got a new clutch after slippage became a frequence occurance.

Went with the Cargraphic reinfored clutch with single mass flywheel

The single mass flywheel certainly revs quicker, but I REALLY don't like the car sounding like a bag of nails in the engine when you accelerate from under 2000 rpm
