Nikolai Loskov: Just give it a little more time and the car will go over 180KMH without any problems.
Nice machine, take care of it and will run forever.
Paulo Pinho: Mine:
85 mph: about 3200 rpm
65 mph: 2200 rpm
But I will confirm; I am not sure...
Justus H: what's your RPM level at 25 / 45 / 65 / 85 mph?
Paulo Pinho: I can afford it if it is a diesel:P
Autogas is a good option, too. I agree.
But I think that buying an S500 or S600 and converting it to gpl (autogas) is not the best option.... Those engines are better original. Probably a S320 would be better to convert.
But I still prefer the diesels (of course that if the consumption wasn't a problem I would prefer much more a powerful S500 or 600)
Paulo Pinho: I agree.
I have one with 350000 km, original engine and it is still perfect.
Some of this cars had problems but mostly in US due to the low quality diesel used there (that can lead to bent rods)..
Paulo Pinho: And the consumptions??
The advantage of the diesel engine aren't the performances but the consumption that is almost half of an S600 V12
Justus H: no dude i think you cannot chip it, at least it wont do anything to the top speed.
Pretty high rpm, is that normal?
Justus H: if you treat that car right and booze up the engine cooling, this engine will be as reliable as any other mercedes engine
guitigefilmpjes: Don't forget that this is an old diesel engine, and when it was new it has been registered with a topspeed of 180km/h (so 200km/h it will never reach for sure;) )
But it seems that after years of hard work it does not even reach that speed anymore.
cfmatias: I love that car, but the same does not apply to the engine... It's not even reliable...
