Recently I have been thinking of an exhaust system upgrade for my 2005 997 C2S which I have been driving for quite some time. Can any of you guy help by suggestion on this issue? My 997 is basically standard apart from a set of BBS forged wheels. I am hunting for something that product nicer sound plus hopefully better flow and performance. Any experience and suggestions on where to shop, please reply. -
Hi Everyone, I have a boxster 01, 5 speed manual, 70k milage. I got it from a person who sold it around 64K. I did a 60K service on it. This is my first car so didnt knew much when I brough it. After I brought the car I noticed that around 3000 RMP it shakes. So after some research changed front engine mount. Also did wheel balancing too. Still small amount of vibration can be felt under my seat when the RPM is around 3000. Have the same problem when enging idles. Recently I have been facing performance loss. I dont rev upto higher RPM's. The best I do is until 4000RPM. But I like quick accelaration from 1500-3200 so I drive just between that mark. When the engine is cold it performs good enough. But once the engine gets warmed up(when the temp. gauge stays around 200 degrees), after a while of driving it looses its performance. I dont get those quick accelearations. Also I have to step on my accelaration pedal a little more(on my top gear). I spoke with my mechanic (JONES AUTOWERKS, San antonio,TX), he rev's upto 6000 and says it works fine. 6-7 mechanics tested that but everyone say its fine. Deep down I feel there is something wrong and would like to know. Previously I used to accelarate between signal lights which I stopped now. Things I felt which may be Culprits: 1)MAF sensor 2)Coolant Tank 3)Any wheel bearings which puts more effort on the engine to turn the wheels 4)Idiling the car. 5)AOS 6)Vacume leaks Recently changed the alternator and read some where that I should not take the car for short trips. Since then I dont stop the car for short trips, so I have to idel it if there are lot of stops. Thats the only car I have so I use it for day to day purpose. But I am not able to judge properly coz the thing happens after engine get warmed up. Also need some recommendations how to drive a manual transmission. How much people generally rev the car before changing to higher gear. And I have this habit of pressing gas pedal a little before letting of the clutch go coz when I change gears it gives a jerk and hence wanted a smoother gear change. But the funny thing is, if I do like that then the performace is not good when compared to not giving accelaration until the remove my foot from the clutch totally. Its like the car is asking for sometime to breath....... I took it to another mechanic and he said that its because its a v6 and so its not that responsive. Banging my head as I want the feel of a perfect drive which is not happening at all.
