Jermmy, Thanks for the info. Very much appreciated. ali

My understanding is that factory placed the RMS backward by design in order to create more negative pressure (vaccum) for the purpose of attaing a few extra ponies. The downside is the possibility of oil leak if the car is not driven frequently. I suspect that with placement of turbo seal in the conventional ("normal") way, you are likely to lose a few HP (which may not be noticeable). If I rercall correctly, this info was provided by Bruce Anderson in Excellence a few years ago.

Jermmy Thanks for the elaborate description and the tidbits to restore the battery function. It was most hepful. I installed an Optima battery in my 05 GT3 last year. My only concern is whether the lithium battery will still have enough rerserve in 25-35 F degree-temperatures. Thanks again. ali

Jermmy" Thanks for the very info. It certainly was very usesful. A couple of furhter questions: When you say cold what temperature are you referring to? You mention turning the "light on" would facilitate to start the car. I presume the headlights; correct? Thanks again for the helpful info Ali

Carmon: It is almost 12 months since you installed the lithium battery in your GT3. Any update on the status of the battery?

You may consider to contact Suncoast Porsche parts in Sarasota, Florida, or Wheel Enhancement. They might be able to help you. Do you have a specific designated option code for black-painted wheel? If so, it should be included on your option list

Thanks for the info. al

"Don't forget these guys. I have heard great things about them from Audi guys and 911 Turbo guys. I guess they will also customize a tune if your close by with your vehicle on a Dyno, that would be optimum. Eurocharged also sells the MyGenuius loading tool so you can do it yourself." I just reviewed their website. Very impressive with good reviewes. Can they actually dyno 4-wheel drive cayenne? Anyway, prices are reasonable, if gains are not exaggerated, or drivability is not adversely affected. I am even tempted to try it on my C55 AMG in addition to the CT. I presume you do not have it on your cayenne turbo s. I wonder if any one here has used their sofware on their cayenne

Interesting. I presume that you do not have dynamic drivetrain mount.

I not sure that the issue is alterations in complinace/stiffness characteristics. I had 993 RS motor mounts professionally installed on my car, and now the OEM exhaust tips are lower. Unless I am mistaken, RS motor mounts are not supposed to be more compliant (less stiff) than the OEM ones. I have no experience with Wevo mounts, but there must be some other underlying variables.

Loren: The viscosity issue is clear. But what is the GL desigation? Is this a new (revised) API SERVICE classification? (I know G signifies gas engines). I can not find this (GL) in the retail stores here. The widely available Mobil 1 is API SM,SL/CF. This is the one I have used and the service adviser at my dealer did not raise any concern. I would apperiate your response. :renntech: Porsche dropped that requirement in the April 2007 list - so I have edited the list. THANKS. :renntech:

I certainly agree with your conclusion. As others have indicated, the most viable alternative is to sell the car and acquire a 996 turbo (which its prices are attracive these days). It has a true dry-sump lubrication system and, like GT 2 and 3, is based on the evolution of 964-993 engine. However, I find it difficult to accept the premise that Ford and Porsche engines are similar. In my view (even though I am not an expert), they are not comparable. Yes, both are internal-combustion engines and both are, in essence, air-pumps. But that's where the similarity ends. The following should elucidate my point: The Ford modular engine in Mustang is 4.6 liter (3 valve configuration, if I remember correctly) with a CR of 9.8 producing 300 HP which gives a specific output of only 65 HP/L. In contrast, the 996 engine is 3.6 L in capacity (4-valve /cylinder). With a CR of 11.3, it yields a greater power, i.e., 320 HP with a specific output of 89 HP/L even though it is smaller by 22%. Now you may argue that Ford engine's torque is higher; that's really immaterial because 996's acceleration times, based on published data, are quicker. The implication is that Porsche engine is a high-tech powerplant, and as a consequence, it would be difficult to obtain a substastial additional HP from this engine because the factory has already extracted, within certain parametres, the near maximal power. Can we get more HP from this engine ? Of couse we can. The prime example is the expensive factory Power Kit raising the peak HP to 345. But I don't believe that you could get an extra USABLE 50 HP without an extensive internal modification. This constraint is not applicable to the Ford engine which is relatively low-tech.

Thanks, Craig for clarification. I was little concerned about these. That's why I have been hesitant to install them.

Interesting. Thanks for the input. Are these somewhat undesirable from esthetic perspective or do they actaully restrict air flow to the radiators? Please advise.

Sorry about the accident. I do hope that you would get a satisfactory compensation. I really think that there should be a yearly mandatory DRIVING test for the elderly (people older than 75 yrs old) to identify the incompetent drivers. I do realize that age limit is debatale. However, it is a fact that there is a progressive age-related decline in visual-motor coordination which can adversely affect driving ability. So, frequent assessment, IMO, is not without merit. This should not be construed as an insult to or discrimination against the elderly. After all, driving is NOT a right but a privilege. Of course, I also realize that there are other conditions that are equally or more hazardous and impair driving profoundly that we are all too familiar with: ethanol, drugs, extended phone conversation and eating; once I saw a woman holding a bowl of cereal? (it was in the morning) with one hand and a spoon in the other hand putting that stuff in her oral cavity while driving (true story)!

You can also check with Austin at TRG. I know they have the protective screens for 996 GT3 (factory cup cars, LT grill #996.505.323.91, RT grill #996.505.324.91, center grill # 996.505.321.92 ). Total cost: ~ $392

Check with Austin from TRG. He may be able to help you. He is very knowledgable and supportive.

Do you happen to know the highest milage 996 GT3 in the States (or North America)? Anyone else? Loren? There's a thread on this over at Rennlist. I haven't followed it closely, but seem to recall that 41K is the high mark. THANKS.

As others indicated, 996 (MK2) GT3 is, without a doubt, a wonderful car and an absolute joy to drive. Whether you can use it as a daily driver, the answer is yes. However, it depends on your level of tolerance and threshold for discomfort, the road conditions (smooth vs. potholes) and possible orthopedic problems . It is certainly not prohibitively uncomfortable, but I must admit that I don't use it as a means of daily transportation. Of course, you can not drive this car in the snow with the conventional tires. As for noise level, it is a little loud but I don't think too loud; you can carry on a conversation conveniently without the need to raise a decible . Having said that, I know that a few of my neighbours told my wife at the a neighbourhood party (which I did not attend) that they know when I am driving the car on Saturday and Sunday AM's. Like others, I do not use the radio. If you are a classical music fan, forget about it, because the musical dynamic range is destroyed (although I have not bothered to try it). May I suggest that you test drive the car for youself because these issues are subjective and you are the only one to be able to determine the positive attributes (which are numerous) and the deficiencies. Is the 997GT3 a better car? I think the answer is yes. It is more refined and comfortable, and also faster.

Loren has addressed this issue very eloquently in his blog. You may wish to review this. BTW, the claim "up to 30 hp" is really meaningless, as the purpoted gain encompasses the range from 0 to 30 hp. Having said that, I am aware that there are reputable tuners (RUF, Manthy and others) whose products can give a decent but modest gain in peak hp, i.e., 20-25 (perhaps even more) for the NA engines. In fact, the factory Porsche power kits for 996 increase the maximal hp by 20 and 25 for the 3.4 liter (which was not available in the US) and 3.6 liter engines (which was available in the US), respectively. Please consider that: 1) these kits include multiple components that should work in harmony to acheive the targeted gain, and 2) they are expensive. It is unlikely that a single product can produce a consistent 20-25 hp gain in peak power, particularly WITHOUT a decrease in power in the low-mid RPM

Congratulations on your new aquisition. Enjoy it. It is wonderful car. I don't believe that there is a "motorsound" option for the 996 Porsche. That option was available for the 993 series. But I may be wrong. Perhaps you mean PSE (Porsche Sport Exhaust). One of the places you can look for the factory installed options is your warranty booklet.

I also remove the dipstick to add oil. Otherwise it's a pain. BTW, the first time I tried to check the oil level using the dipstick, I panicked, as there was no visible oil on the stick (I followed all the instructions and procedures in the manual), and yet the electronic gauge on the onboard computer displayed half full. I had just changed the oil and filter at my dealer. So I called my service adviser, and also the adviser at the Brumo in Florida. They both told me that I did not need to bother with the dipstick because the e-gauge on the OBC is highly accurate. Nevertheless I added 250 ml of 0W40 oil (one measuring cup) which raised the level by one segment (1 segment= 0.25 liter per manual). The oil quanity with filter is 9 liter (9.6 Quarts) for GT 3, according to the owner's manual. Does this number represent the total amount (capacity) so that the quantity to be repalced is less than that? Thanks for the info and advice Regards, Ali
