ajh Posted May 29, 2010 Share Posted May 29, 2010 What speed should a healthy 200TDI 90 be able to maintain on the highway with BFG A/T 265/70-16s on? I just drove the new 90 back from Halifax and I don't remember the 110 having trouble with maintaining speed on the hills, etc but the 90 seemed to struggle somewhat. I am suspecting the turbo, but would appreciate knowing what to look for to figure this one out since the 110 is still currently in the workshop and not-quite finished.

Marks 110 Posted May 29, 2010 Share Posted May 29, 2010 My 110 when running well will maintain 70mph-80mph on the flat. Speed may drop to about 60 on long motorway inclines. I would say if it can't maintain 70 on falt roads then something is wrong. I would check elsewhere (cheaper componants) before changing the turbo. I've just fitted a second hand engine which seemed to cure smoke problems which I had associated with the turbo. Mark Quote Link to comment Share on other sites More sharing options...
jbs Posted May 29, 2010 Share Posted May 29, 2010 Servicing Lift pump Valve clearances Lower ratio than standard transfer box ie: 1:668 instead of 1:410 ala defender? Clagged up intercooler(internally) Intercooler pipework collapsing inwards Knackered injectors Fuel injection pump and lastly the turbo itself Quote Link to comment Share on other sites More sharing options...
