So, "a friend of mine" did a little speeding today. Turns out, the d@mn thing won't do more than 250km/h. At 250, it's as if all the juice is out. It pulls strongly up to 240, 245 and then it sort dies... You feel the car going powerless. I mean, it's not the same feeling as when you've reached maximum speed, you know, like it stops accelerating gently and then stays put on a certain speed. With, let's say, my Jetta, the feeling when you start to reach top speed, is more like "it wants to rev more but won't" - this was "apparently" more like "it revs, it revs, it's not revving but staying put, a sudden change in acceleration". This is more of a sudden event, as if a speed limiter went in. The change in acceleration is so noticable, it's as if the turbo won't deliver any more flow/pressure. The car has a 295hp MTM chip. There were some fault codes a few weeks ago that haven't been investigated though, but should they effect this? Throttle sensor (intermediate), both home- and rpm-sensor (intermidiate). It is a bit jerky, you know, it twitches on the way up there, my guess, however, is that the jerking and twitching is due to home- and/or rev-sensor.
I realize that 250 is fast, but the way it sort of "dies" up there feels wierd. I don't know, could this be a sign that the turbo is starting to reach it's end? It does seem to use up some oil too. Oh, and 250, that is according to the speedometer, I know it's not true speed, but it's used here too describe the symptoms.
Maybe you guys could help my "friend".
