  1. I have seen some third party offer the Bi Xenon headlight replacement bulbs with higher temps.
  2. Let's not go there you have no clue what my backround is! You really are just throwing around what you see on the internet, and have no idea how it ties together! Just for your education, firmware is written to meet certain criteria the manufacturer is seeking. So go read some more, and get an education on Software and Digital circuitry developement! Then we can have an intelligent conversation! The sensor will hear more but does not mean it's a cure all. There is more to it then just a listening device! Your previous posts says all that is needed to know you are just arguing for the
  3. Actually the current knock sensors are broadband single wire and flat response two wire knock sensors. My response is up to date. If the sensor was responded to for all harmonic frequencies it would never allow the engine to run at it's full potential since engines harmonics are not all due to knock. They still have their specified window! Therefore a base line has to be configured. Once agan a knock snsor is not the cure all! Think this topic is worn out!
  4. rslinger - I do not have any info to say if anything above 93 will net better performance. ihave heard that 100 in higher temop condition works well, but no validation if iti s true. I know if you go too much it will go negative. Think you might want to ask the question on some porsche race sites
  5. KevinMac, I was considering the RE960AS as you said but they are not approved by Porsche. I was trying to stay with what they approved. However, since I have a wide temperature variation to deal with throughout the year I don't think it is feasible to have two sets of wheels and tires. Did you switch to the Bridgestone all around or just on the rears? Have you noticed any difference in handling? My opinion the Porsche approved which has the "N" designation just means that tires meet the design criteria of the Porsche design. This by no means that the tires without the "N" designation
  6. I had the Conti Conta 2's they don't last and get noisey. Carrera's are known for rear wear out quicker than fronts. Withthat said I have gone to a set of Bridgestone Potenza RE960AS Pole Position, which supposedly have 40 K tread wear out guarantee. I can't say at this time since they are to new, that they will make 40K. I can say they out perform the Conti Con 2's, from a handling, noise and ride perspective. So when the Contis are gone take a look at them. Tire rack has very high marks for these.
  7. Such a stubborn, condescending view begs for other opinions. Here's my 2 cents. It doesn't take a "self proclaimed expert" to know that there is fuel in the tank without using a dipstick. The expert can monitor the fuel level gauge and if there is no reason to disbelieve the gauge, he can tell the level from it. Much in the same way, a "self proclaimed expert" can monitor the "combustion profiles" (boy there's a twenty dollar phrase) by monitoring knock sensors and ignition timing "profiles". The knock sensor feedback is quite simply a monitor of "There is detonation" or "There is no detona
  8. wwest - think you just like to argue for the sake of an arguement. Your the one that posted low octane in Europe. As I posted their low octane is = to 91 in the US = within spec of the porsche spec! So what's your point! Point me to where does Porsche says regular, all my documents including the maintenance manual says Ron 98 = 93 Ron+Mon. That's what's funny you are all over the place with your comments! Low octane 87 in a twin turbo, that answers it all. Thanks for such a competant answer! Now I know where your knowledge really lies! Your true colors are really showing now! Nice
  9. I hope the mods are not the reason you can stay with a GTO, hopefully the GTO you are talking about is the 400HP version, since the published specs are pretty close with the 996 edging the goat out in 0-60. ( based on published #'s after test drives) Anyway be careful with the cold air intakes, some suck in hot air and may cause a lower output. I agree the published numbers adverised by OEM mods is over exagerated.
  10. It cost me about $120 before shipping. Use the collision catalog search boxes. Bought it here: http://www.trademotion.com/partlocator/ind...CFReQGgodj2UgCA It's not a tuff thing to do, everything snaps off just becareful when removing the storage box switch and wire. If the current storage box has the old hinge set, you will also have to buy the hinge kit, not expensive. Use the instuctions to change the shifter out to a short shift kit. It has all you need to remove the console. My only suggestion is when you remove the side cover that encloses the handbrake lever. Wrap the lower section
  11. Good luck, I searched high and low and could not find a match (graphite grey), wound up buying a new center console, which really was not that much of a wallet hit.
  12. So let me get this straight you are comparing a Mazda CX 7 a passenger crossover vehicle vs a performance car, wow! We are talking Porsche a performace vehicle!. Once again would you really put 87 octane in Carrera turbo "street engine"? Well if you don't know what a performane tune is, which there are many avialable for Porsche, how can you comment on the acceptable fuels to use? Oh btw if I remember correctly most European countries have a minimum or "regular"@ 95 RON which is = to 91 in the US. Kinda matches the octane recommendatin in the owners manual 91 to 93! Funny how that wo
  13. Okay, question for you, then. With the A/F mixture and ignition timing "mapping software" so easily malable/modified and regular fuel less expensive and such a common thing why wouldn't the parametric mapping ALWAYS allow for the use of regular fuel. What's the harm...?? Wouldn't it take a somewhat idiotic engineering team, engineering management, to overlook such capability..?? Allow an engine, "street" engine, to be damaged as the result of an owners simple oversight/mistake...?? NOT..!! No because they already specified the fuel that should be used! Porsche and other performan
  14. I bow to the self proclaimed experts who know nothing about the mapping software and insist that the scanner watching the sensors tell the combustion profiles! No longer worth the discussion! Do what you like it's your vehicle!
  15. And wouldn't it be somewhat idiotic for Porsche to design a car that didn't have enough parametric mapping range, A/F mixture and/or timing adjustment, for use in a country/region/continent where premium fuel is often not available...?? Your right and premium is not available in all areas, that's why Porsche says you can run 91. Droping 3 points is ususally not an issue, but 6 can be! Sensors are not going to tell you anything other than they are working and depending on the one you have you will see what the outputs are. Will not tell you the combustion profile! You have no clu
  16. This is all speculation, anyone without seeing the maps to say the computer will detune to 87 is just making assumptions. I believe it will to 91 but since the recommended is 93, I would not make that assumption! I know for a fact that maps that I was involved with Ford and GM, the threshold was not that robust to allow such a wide margin of error. Yes it will attempt to retard the spark, and adjust the fuel flow, but some maps are not that robust to get you that far below the recommendation. Based on the lower limit of not allowing it to detune that far it can only offset some detonati
  17. Hate to tell ya, Porsche does not recommend anything past 18's on a 2000 C2. The suspension is calibrated. Read this: http://www.europeancarweb.com/tech/0505ec_...ires/index.html
  18. No. It will not hurt the car. I disagree, if the computer does not have enough threshold to detune to 87, yes it could hurt the car by detonating. Just the mere fact you are over 11:1 compression ratio, I don't think the maps will accomadate 87. So throw in octane booster and when down to 1/2 tank fill it with 93 and octane and booster again. Do not drive it hard until you can at least get 93 and octane booster in together.
  19. It could be just a bad connector to the coil that is causing you grief!
  20. If that were the case you would have a noisey valve train, and this was not in the post. If the noise is not present, it sounds to me they are just throwing parts at it. Based on the post, I would be very skeptical about the diagnosis.
  21. If the rainfall was really part of the problem, it surely would not be the valves. Maybe the rain and the problem are coincedental, Was a compression check done and if so what were the numbers?. Where there any codes beside #5 missfire. I would get a second opinion!
  22. I checked the receipt and the dealer had put in 15x50 Mobil 1 at last oil change. Was planning to change it after the Summer, but alas, I didn't need to do that. Just needed to mop up a few gallons from the garage floor and then the street once the flatbed wrecker showed up and we pushed it to the street. I will definitely not run that viscosity in the future, as it's not THAT hot here. Sent a PM regarding price (roughly, in the $41k range). Thanks for the good wishes - I'll keep my fingers crossed for a new engine, and will post back once I hear from the dealer. Wow a Porsche deal
  23. Perry - I agree with you when you compare base number as the temp rises Mobil 1 0w- 40 compared to 5w- 50 has a higher viscosity index number at 100 deg C. The discussion was around Mobil 1. 0w - 40 cSt @ 100º C 14 5w- 50 cSt @ 100º C 17.4
  24. Yes the center console is plastic, and if you want yours painted as Loren said it needs to be preped. The actual paint the factory uses is not really a paint as we know it. It actually is a coating more like a dye type coating. http://www.bumperplugs.com/BPindex.html
