    Too much fun

    Joe, sounds like the wife has given a repreive of sorts.... you've got couple more months then to decide for sure if you can live without. I've no doubt the C4S is a great car, and I've enjoyed a few drives in them. Hope you end up finding the right balance.
  2. the wider rear end is the best single giveaway... badging would be 2nd
  3. Kevin, I'm no expert and you may be... I wasn't assuming some unlimited boundaries on ECU mapping, but I and several others I've run with can attest to higher octane fuel making a noticeable difference on days at Thunderhill with ambient temps over 85 degrees. Question?.... if the ECU capabilities are limited (effectively not cognizant of the difference between 87 and 93 octane), that would mean our ECU has no way of countering differences in fuel quality? Seems odd.
  4. It's worth noting that in many circumstances higher octane fuel does indeed provide greater performance by allowing our engines to avert retarding the ignition. Porsche uses knock sensors to tell the engine when to reign things in. On hot days at the track for instance, you might be surprised how often engine ignition is being retarded to save itself. In any of these scenarios, there is a measurable and felt difference by running 100+ octane fuel, so while many of you are correct in saying that higher octane fuel does not provide greater horsepower in and of itself, there are indeed many c
  5. I bought a set of Pagid RS-19 pads to swap in for track days. They howl like a frickin wolf but work quite well and don't dust at all. I have one more track day in November and will enjoy putting my OEM pads back in, as the little bit of squealing that comes from them never bothered me in the slighttest. The OEM pads are not quiet, but there really isn't any such thing as truly quiet, effective brakes that last a reasonable amount of time. I think Porsche/Pagid have found a very good balance in the OEM yellow compound on my GT3. i.e. Flash, don't expect to find pads that improve your curr
  6. I know there's a lot of info out there re. all exhaust enhancement options. I'm curious what the breakdown of owners who go, with performance mufflers only, full system or the PSE style mod to OEM mufflers? I'd read the reams of info. and opinions on what sounds best, more interested in which method wins. BTW, if you have a set of OEM 996 mufflers you're willing to part with, please email or PM me.
  7. Ward, Don't expect a harder ride out of 5mm wheelspacers... Nick, can you provide more detail on your observed ride changes after adding spacers? While it would increase the leverage your wheel/hub assembly has on the suspension geometry and damper, it's odd that the ride would get noticeably sharper or harder. Such a change almost sounds like your dampers are worn out and blowing through their stroke on compression.
  8. The more performance oriented the brake pads, the more likely they are to make noise. There are exceptions, but this is more the rule than exception. You guys should try getting GT3 or cupcar brakes to be quiet at low speeds and just near stop. You simply learn to live with it. Use your brakes in good health and enjoy their capabillities. Porsche has done a good job at walking the line between sportscar/racebred power, feel, and bite and civilized passenger car quiet brakes.
  9. dumb question here.... anyone know the differences between GT3 mufflers and std. 996?
  10. Carlos, Please, please, please don't run your Boxster without an air filter!! :P I know you long for those glory days with the old Mustang, but while your Boxster would continue running 10 years from now, it would also be measurably down on horsepower.... just as I'm sure your Mustang was. Peer, It seems as though K&Ns and their competitiors have all been coming oiled in recent years, though there may be exceptions. With K&N it's very easy to tell... If the cotton gauze is pink/red, then it's oiled and ready to go.
  11. John's advice is sound. The question is not whether your engine will grind to a halt a year or more from now. The question is... is there substantial evidence that this filter will enhance the performance of my stock Boxster?, I think the answer is, no. I believe that a K&N style filter is only going to make a reasonable difference in the Boxster when it's used in a well designed replacement intake, not the OEM unit. And frankly, even under that scenario, we're not talking about enough horsepower to notice the difference or justify the cost. Don't risk your $10K engine on a filter
