I'm about to get an alignment done along with new rubber. I'd like to be armed with target specs for the Tech. Does anyone have a good set of factory specs for a 997.1 C2 (not S) with 19" lobster fork wheels, and stock suspension? Street driving only. Looking for maximum tire life without sacrificing too much performance. No track use. Thanks in advance.
terpsred replied to Black Stig's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)I have a new to me 06 C2 and it is exactly the same way. The car always starts, but the starter motor turns over at a slow revolution rate compared to a honda for example. I've talked to many 997 owners on the subject and it seems to just be the normal sound for this engine. Mine takes about 5-6 revolutions to fire up as well.
terpsred replied to terpsred's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)No, I don't leave the car in gear at lights I put it in neutral and let out the clutch. I don't think it is the bearing as it makes no sound when sitting still, or in/out of every gear. The sound only occurs when the car is warm, and when the clutch is right at the point of full pressure, and almost matched with the driveshaft speed. Anything is possible, but I would think that if it were the throwout bearing, or clutch fork that it would happen when sitting still just pushing the clutch in and out, or at least in other gears. - Any thoughts?
I've just noticed a clutch squeal/moan right as the clutch pedal releases all the way out. Only happens if I'm above about 1500RPM as the clutch lets out. I've read on past threads that it is "normal" and that it could be a glazed pressure plate/friction plate. The car only has 18k miles and is still under CPO for another year. Is it OK to let it ride for a bit (Just annoyance) until I put the car in for the 20k service? Or should I make a special trip to address it? It only happens in first when starting from a dead stop, and only happens right as the clutch lets all they way out (Full hydrolic pressure release). When slipping the clutch up a driveway, there is no groan, and the clutch grabs fine during normal operation, no slipping when rolling. I have a 2006 C2. No racing, no light to light drag runs, no track days, etc. I did notice that the squeal is only there if I'm letting the clutch out between 1000and 1300 RPMS. If it is faster than that (RPMS) and slipping more, there is no squeal. If it is a very gentle launch, there is no squeal. AC on or off, no difference PSM on or off, no difference It is almost like there is some perfect harmonic point where the clutch/transmission friction causes a squeal when there is barely a difference in the rotation speeds. I've never personally dismantled a clutch but I can envision the friction and pressure plates barely turning at different rates causing some noise, where a greater difference skids without noise. any ideas. Since I'm under CPO should I push for a replacement? Thanks in advance
