  1. Uwon,


    "I'm not sure that I agree with you. PS2 pricing is outrageous! N spec is overrated IMHO. Super Sports or R-11's would be my likely choice for the next set. I have heard enough from fellow PCA members all who stay away from PS2's unless they track.


    You are certainly entitled to your opinion, and yes they are expensive. It is natural that PCA members have different preferences and opinions. However, as member of PCA for 23 years, I beg to differ. I have N-designated PS2 on my 997.1 turbo, and I am very satisfied. The grip and turning are excellent; the tires are quiet, and somewhat comfortable, and they are OK in the rain. They are certainly better that  Bridgestone Pole Position that I had on my 2003 996 with ROW M030 sport suspention. This is my personal view.

  2. These are over-revs. There has been over-rev hysteria, alerting potential  serious engine damage due to high over-revs caused by missed shifts. Sure engine damage can definitely occur as a consequence of missed shifts. However, not all over-revs even in high ranges are the results of missed shifts. Therefore the question here is the significance of 1 ignition over-rev each in ranges 4, 5, and 6. In the context of 3 ignitions per each RPM, One ignition would amount to only a small fraction of one second, considering the high RPMs extant in the above ranges. There is NO way to attribute these to missed shifts (manual transmission!). It is humanly impossible. It is more likely due to the computer/software flukes/aberrations or other unknown (at least to me)  mechanisms.


    It is well known that Porsche does not CPOs the cars with pathological over-revs. When I bought my 2003 996 several years ago, it was certified by Porsche even though it had 1 ignition over-rev in the range 2 (please note that in 996 there were only 2 ranges: one and two); I drove the car for 6 years with NO engine problems. Even the original IMS bearing was in excellent shape before I replaced it for prophylactic reasons.

  3. I must clarify the following:

    The 4100-4200 RPM limit is always the rule when the engine is cold and is not within the normal operating condition. This rule applies to all Porsches, all the time, and  regardless of how many miles the car is driven. I think most of the Porsche owners are aware of this rule.

  4. Root,


    "After 500 miles I went to 7500 routinely. After 750 miles hit 9K a few times. Since 1000 miles I go as high as conditions, traffic etc. allow.. Master techs and others in the know say I have been too cautious."


    Thanks; that's very helpful.

    "A beauty, enjoy.

    Mine is a month old now; 1400 miles and several trips to 9K. The sound and whiplash in PDK-S manual between 7.5K-9K

    is a whole new world"

    Thanks; looking forward to experiencing 7-9K RPM. At what miles did you start to exceed 4200 limit? Currently I have

    5600 miles, and have begun to go up to 4600 occasionally. I recall the late Bruce Anderson, a real Porsche guru,

    suggested that after 300-500 miles, drive the car aggressively, "drive it like you stole it"

    As you know it is very difficult to adhere to 4200 limit if you are shifting manually because, in lower gears, the RPM rise is incredibly quick.

  6. White987S

    "How Does Voodoo Blue compare to Riviera Blue or Mexico Blue in real life?"

    Among the 3, Riviera blue is the lightest, Mexico blue is medium, and Voodoo is the darkest with varying hue.

  7. So, what you are saying is that there was no problem with your PSE, correct? I have used PSE on my GT3 many times. It is slightly louder at idle, but noticeable in a quiet environment. While driving, the only difference in sound is detectable during rapid acceleration (up to 4200 RPM, of course; it may become louder at higher RPMs), compared with baseline.

  8. I posted earlier to inquire whether anyone has purchased and driven 991 GT3 to share his/her experience.


    I ordered, and picked up my 991 GT3 about 3 weeks ago (PTS, red dials, stitchings, and belts, LED headlights, front axel lift, sports chrono, leather interior, sports adaptive seats, extended fuel tank, clear side markers with LED lamps, and a few other options).


    All I can say is, for far, it is an amazing car, Notwithstanding that it would be difficult to make a true objective assessment of the car performance due to mandated 2000-mile brake-in limitations (4200 RPM max), it is an absolute joy to drive this car. I have driven the car for more than 500 miles now, and I would like to share a few attributes of the car:


    1. Throttle response is lightning quick.


    2. PDK sport is great; gear changes are almost instantaneous (even in normal mode); I usually use the manual mode. Frankly, I could care less about pseudo-experts demonizing the car because of absence of manual transmission or the buyers who choose PDK; just to clarify, I have been doing heel-and-toe (or more appropriately phrased toe-and-heel) gear changes for the past 30 years (sometimes I use the double clutch technique to revisit the old habit); it is second nature to me, and I don't even think about it when I am doing this. Nevertheless, for me, PDK sport in GT3 is light years ahead of manual transmission, and I would have ordered the car with PDK even if it were a costly option.


    3. Steering is wonderful, even though it is electric. To the chagrin of traditionalists, it is certainly  better than my 2007 997 turbo (with a manual transmission), or even better than my previous 2005 911 GT3 which I drove it for 8 years.


    4. Brakes  are second to none. I have standard cast iron disks.

  9. It may be too late to respond . Nevertheless, there is, at least for me, only one choice, and that is 996 GT3. 996 turbo is a great car, and undervalued (still a Mezger engine) but it is not as entertaining, fun to drive and challenging as GT3. I have owned mine (2005) for almost 8 years now.  Regrettably, I have to sell it because I am getting a 991 GT3 this month and don't have space to keep it. 

  10. Thanks everyone for responses and helpful suggestions. The rationale for my initial post was based on the premise well articulated in the Porsche manuals, as Porsche advises us not to exceed 4200 RPM until the engine has reached the optimal operating temperature. In 996 cars (M96 and GT1-based engines), the only available indication for normal operating range is coolant temperature gauge. In 997 and Cayenne (and perhaps other newer models), there are two temp gauges: coolant and oil. I have observed consistent temporal differences between coolant and oil temp gauges in both of my cars (997 turbo and Cayenne TT), with the oil temp rise always follows the coolant temp regardless of ambient temperture (in colder weather the difference is larger).

    So the question is which one is more reliable reflection of engine operating temperature in early stages of driving, or does it really matter?

  11. I am not certain that this has been discussed in the past. Nevertheless I would like the revisit this issue:

    Is there anyway to gain any info on oil temperature while driving with the use of the onbaord computer on the instrument panel in 996 Porsche? The reason I ask this, is that coolant temperature does not always reflect oil temperature, particularly when the engine has not sufficiently warmed up. Under these circumstances, the oil temperture lags far behind the coolant temperature.
