Revving the B***S out of it.; Engine revs

Hi everyone, i drive a 1991 190D and was wondering if it is OK to rev upto 4k when changing gear. There are a lot of hills where i live and to keep up with traffic it seems to work well. I only rev this high when the engine reaches it's normal temp, but is it OK for this engine. It is the 2.0 litre version. We all know how slow they can be! On the motorway at 70 it revs around 3k anyway so i assume they were built well enough to deal with it. Any diesel owners out there who can put my mind at rest. Thanks.

ALL Mercedes engines , provided they have been properly serviced and oiled , will rev clean up to the red line on your rev counter .

4K should be a walk in the park ...... :P

Thanks Jeremy, maybe it just sounds like it is revving high as my rev counter only goes up to 6k and there is no redline. Still getting used to the car but i enjoy owning it.

red line on a old diesel is 4.5k and yes its ok to rev it to that.............i bounce mine off the limiter all the time :rolleyes: .....................and it you want to make more drivable do what i did,and make your own exhaust..............doubt if it increased BHP but boy it is ever nippier :) . i have a 2.0D and people who have seen it will tell you it aint slow !! :)

Yes , I forgot to add , you cannot over-rev them coz they have a rev-limiter which is always set consevervatively .

I have a 2.5-16V , very well maintained , and I rev it to its 7200 rev limiter often .......... :P

Rev-up & enjoy .......!!!!!

(& watch your fuel consumtion rocket :S )

Thanks for the replies! I have never taken it to it's max as it seems to cope quite well so i will just enjoy it. I am interested in the exhaust mods! Would making your own exhaust cause problems at the MOT? How much more umph does it give you? Cheers.

nope,not as long as you are within the noise limits.......................i have a standard down pipe,but from the first joint its a 2 1/2 inch straight through pipe,and the only silencer is a magnum back box,and mine is well within the noise limit, and it has a real nice burble,and sound nothing like a diesel ;) .............BTW you have to modify the air in take as well ,as this is very restrictive...............remove the trumpet section from the air in take a put a straight pipe in,i used from a citroen xantia ;)
as far as uumph goes,as i said i dont think it actually increases horse power but what it does do,is make the throttle much more responsive and free revving,making the acceleration comparible to a 1.8/2.0 petrol 190 ;) :)

Sean no disrespect but I have a 2.5 Manual with a 3.5inch straight through pipe and the air filter restriction bit is removed and although the speed is adequate and I think its a great car no way does it compare to my 2.0 Auto speed wise! What are you giving your 2.0d to drink? lmao

I have a 2.5 Manual
thats you're problem.......................people think because they have 1 cylinder more that it should be faster...................nope :P you might have 1 cylinder, 500cc and 20 hp more but the truth of the matter is the extra weight you have as a result of having a extra cylinder far out weighs the gains.
heavier springs,bigger heavier brakes,the weight of the extra cylinder......................plus you have ABS ,i dont...and so on............i wouldnt be surprised if your car was 80-100kg heavier than mine.................i dont even have a rev counter FFS !! lmao

plus i fitted a diff from a 2.0 petrol car,so that might have something to do with it as well ;)

Mate after this thread 'The Gorilla' :lol: started a few weeks back I reckon that 2.0 petrol diff is the one which has given your car a proper edge.

i wont deny it probably added to it...................but it isnt solely responsible for it ,as i had felt a considerable difference before i swapped the diffs out :)

Would you notice much difference just modifying the air intake. Would it burn less fuel by breathing better? It looks like it would be the least expensive and easiest thing to start with. As soon as i say easy it becomes a nightmare!

not without doing the exhaust as well,its to restictive-wont allow the gases out fast enough ;)

I'm sure i have read that adding LPG to the system gives a healthy power boost to diesels. Is that correct?

A quick search came up with this.

Rather expensive to fit i'm sure but interesting all the same.

A fantastic new system called Gasmatronic developed by our suppliers (for small vehicles to 40t trucks) and can be added to most diesel engines. Besides the system adjustments, the driver can turn the system on or off at anytime, from inside the cab or it turns off automatically with the ignition key. The reason that LPG/Propane works so well with the diesel engine is because LPG/Propane acts as a catalyst with diesel fuel. By adding LPG/Propane to the diesel fuel you will burn almost 100% of diesel fuel, instead of 75% to 80% of fuel you now burn. That's why there is such a dramatic increase in Horsepower, torque and fuel economy. With the gasmatronic systerm, because LPG/Propane burns cooler and cleaner, your engine in turn will run cooler, cleaner and last longer. Engine response is much smoother and quicker when you add LPG/Propane to your diesel engine.

Benefits

Reduced NOX and particulate emissions are the most outstanding benefit. There are other technical non-pollution related gains, reduced crankcase solids, reduced injection service and longer acceptable oil drains. Diesel exhaust odour is also reduced.

The system is easily transferred from vehicle to vehicle
The system can be adapted on any turbocharged diesel
Horsepower increases 25 to 60%
Fuel economy up to 20 to 50%
Torque increased 30 to 60%
Maintenance cut by up to 50%
Helps prevent turbo lag
Cleaner oil
Engines can last up to 4 times longer
Horsepower and torque gains from 25 to 60%
Smoother and quieter engine
Less maintenence costs
Fuel cost cut by up to 50%
Cleaner engine
Best of all power
LPG the performance fuel
Good fuel costs less, don't settle for less






some pretty outrageous claims there stu :rolleyes: lmao

A friend of a friend had an Astra G running DervGas and it was bonkers, completely night and day conversion.
