Turbo Question

Hi all how can i tell if my turbo is broken or on its way out ? The thing only moves the neddle on the dash half way up some times a few mm into the red but nothing great Its a B200FT 940 se '92

Thats about normal for a standard car. It should be about 6psi. If you are interested you could hook up a proper gauge to check it. I watched a video on Youtube of a 940 turbo that had been tuned. It showed the boost gauge going right round off the scale (by quite a bit) and corrisponding movement of the rev counter and speedo ! My car is set to 15psi with a gauge and the standard one goes right to the end of the marking.

arh good so its not me then lol i thought some thing might be worng first time ive had a tubo with a gauge (Had a BX turbo) I just dont realy feel the thing kick in but if i press the pedal a bit hard it moves and a bit harder still she can fly quite quick (if its already rolling and its flat)

Here's the video, just for reference.

The fuel gauge probably moves at the same speed in the opposite direction. The smoke might indicate that something is slightly wrong, you will get a bit if the weather is a bit cold though. Keep an eye on the oil and water levels to be on the safe side.

oil and water should now be fine Had to replace one water pipe by the oil filter and the oil feed pipe to the turbo had at some point in cars live poped off sprayed oil every where and was never fitted on right so always driped out oil and lost about 3 lts a month thou this its only when i realy put my foot down thou it smokes for a few secs

White smoke is caused by oil passing the seals in the turbo and vapourizing in the exhaust. It could be a sign of excess back pressure due to a blocked breather system.

White smoke at idle is sometimes an indication of turbo wear. I might have the same problem.
