  1. Hi, That fluid is absolutely not recommended for the Tiptronic S! I contacted ZF-Getrieb directly with this question and their reply was that only ESSO ATF LT 71141 was the proper Fluid to use. Also, that use of other Fluids can accelerate wear to the Clutches. Hope this helps... Happy Motoring!... Jim'99
  2. Hi, I think your Evidence is purely anecdotal and your Cause and Effect totally circumstantial. There is waay too much mysticism surrounding this totally innocuous length of tubing. The snorkel is a Noise Abatement Device to comply with Noise Abatement Laws prevelant through Europe. Porsche leaves it on ROW models to prevent the cost of redesigning the intake. I de-snorkled my Boxster 3 mos. ago and haven't seen even a 0.1% drop in my MPG. In fact, we took a Sunday Drive through the Wisc. Backroads last weekend to see the Color and I got 30.1MPG on the Expressway get
  3. HI, Take some double-sided Foam tape and cut it down into thin strips then attach it to the Roll Bar and insert the Windstop. The Tape will do two things; it will adhere to the Roll Bar and Windstop and it will act as a wedge to make the windstop tight. It works great. Hope this helps... Happy Motoring!...Jim'99
  4. Hi, Once a Tire has been punctured, even though it can be repaired (if a Tread Puncture only), the Tire has been compromised and should NEVER be driven at excessive speeds. Once a Tire is repaired, it's ability to shed heat is also impaired, especially in the area of the repair. Driving at excessive speeds can heat up that part of the Tire to where it can delaminate or a Blowout can occur and is simply Foolhardy and irresponsible. You don't want either of these things happening at high speed. There is only 1 proper method of repairing a Tire. The Tire must be plugged, but al
  5. Hi, If you had any sort of air leak, you'd be exhibiting a Lean condition if the leak occurred downstream of the MAF (since it would have allocated Fuel for a lesser mass of air going to the intake). If it occurred upstream (and the MAF was functioning properly), it would account for the additional Air Mass and allocate more Fuel. If you had a clogged or partially clogged Fuel Filter, again less Fuel (or a Lean condition) is more likely. This makes a faulty MAF and/or Faulty O² sensors the most likely culprits. Since it's unlikely that the O² sensors from dif
  6. Hi, One caveat, if you push the wheels too far out, you run the risk of scarrring the side panel with all the gravel and peastone you'll toss at it. Happy Motoring!...Jim'99
  7. Hi, I knew one of them was backwards, I took a shot and said the engine. Now that I think of it, it should be more likely to be the tranny. Thanks!... Happy Motoring!...Jim'99
  8. Hi, Uh... not to state the obvious, but on the 996, the tranny is on the other end. This means that the engine turns the opposite direction. So it's also necessary to transplant the tranny. If not, you'll get 1 Forward Gear and 5 Reverse gears...;) Happy Motoring!...Jim'99
  9. @jnc, To clarify, you stated that "AFAIK... Diodes, should have no ripple. They take AC and turn it into DC. I would think if they have a ripple, then they are bad." This isn't exactly correct. True a Diode should not have a ripple. But, as in my description of how the Alternator works explains, essentially, you have three (3) separate pulses (for lack of a better term) of current being produced. There is a slight delay between these pulses and this is the ripple which is being detected. So, there should be a ripple detected, if not, then one or more of the 6 Diodes (because t
  10. Hi, There are a lot of smart guys on this forum (much smarter than me), so I thought someone would have jumped in to explain what was really happening and how to simply test your Alternator. Since no one has, I thought I'd give it a go. To begin, an Alternator is not a very efficient way to produce electricity for a car. First, it produces Alternating Current (AC), which the car cannot use, so Alternators must rely on diodes to rectify their AC output and convert it to Direct Current (DC) which the Car can use. Second, an Alternator requires two watts of energy to spin it for
  11. Hi, I know I read somewhere about Porsche adding 6-8 HP to the TipS cars over the Manual to compensate for Parasitic Loss due to the Torque Converter. I was especially struck by both how innovative and forward-thinking this was, and that no other car that I know of does this. Because of the small increase, I assumed it was accomplished by the DME. It may take me a couple days to re-locate the source, but as soon as I do, I will post it here. Happy Motoring!...Jim'99
  12. Hi, For NA cars, going Cat-Free will have minimal gains, if any. The reason is that some Backpressure is desirable to maximize the scavenge effect of the exhaust. Reducing the scavenge effect (because the exhaust pulses are elongated) will rob some HP and these effects are most seen on the Low-End. Add to that, the Cats today are much more Free-Flowing than even a few years ago, meaning that removing them simply doesn't yield that much of a Net gain. Then, as you mention, the ECU (DME in Porsche parlence) will go into a default MAP if it sees things which are too screw
  13. Hi, I did a similar Hack, but put the opener in the Center Concole, kept the 9 volt and used Velcro patches too. I used a MO switch and a small LED Indicator light (easy wiring scheme) installed into the Blanking Plug for the Heated Seat Switch (don't have 'em). This way, the switch is within easy reach and I have an indicator light showing the opener is working. It came out looking very good, looks stock, no one notices it (and that's the point). Happy Motoring!... Jim'99
  14. Hi, Sound will deepen, performance gains are moderate to non-existent with a potential drop in low-end performance. You will have operating issues if the 0² sensors aren't dealt with. The DME compares the voltage readings of the pair of 0² sensors dedicated to each bank both pre and post-Cat and between each pair (OBDII). I know that for the Boxster, the distance between the two is also significant and there s/b a voltage difference as well. If the DME does not read this, it will run/start poorly. I know that for the Lotus Esprits (I own one too), the fix is to add a
  15. Hi, My understanding is that there is a difference between the engines for a TipS and a Manual. Porsche slightly upped the HP for the TipS engines to accomodate Parasitic Loss from the Torque Converter. Of course, this may merely be a function of the DME Maps, that I don't know. Happy Motoring!... Jim'99
