do you have a thread on it, or could you go into what modifications you did to the injection pump?

Im at that stage now, I have a turbo installed and operating, and I need to turn up the pump a bit

See if this link works for pump tuning

Does anyone know the weight difference between an OM617 vs. OM616 engine ?

In the gasser world, there are cliches that 10 pounds = 1 HP, et cet.

Some other folks say you take the weight and divide by HP. OM616 in a 3,200 pound car, et cet.

The OM617.952 factory max was around 125HP, so that's 1 HP for every 256 pounds of weight. Folks can check my ciphering ... ran out of fingers and toes.

OM616 factory max was around 72HP, so the weight to HP is a lot more, around 42%.

So, reducing the weight by engine types but boosting the OM616's HP to equal or exceed the OM617 seems in theory to produce some pretty impressive performance gains. Obviously, I left out a bunch of factors such as torque, gearing, parasitic drag, et cet.

Very very interesting work and R&D.

I just bumped my thread regarding different types of 616, I hope to get the w115 turbo-ed this year and hopefully bump the hp from the factory 60 up to about 80 or so, which should help increase drivability tremendously (still better to drive than my dad's w123 240D though )

Just an update for those looking at this post. I now have about 50,000 miles on the engine and it is still running great. Best thing for the car. I have not changed injection pumps to one with larger elements, so just stock pump nicely tuned. I know I am leaving some hp on the table but have not had the time to mess with another pump. It out performs my old( 85 turbo) 300 so that makes me happy.

Any idea about how much hp/torque it makes? I'm hoping when u finish my w115 it should be pretty spritely since it's about 500lbs lighter than a w123

I have not dyno'd it so really do not know. If I throw numbers out then you can bet there will be plenty of folks jumping on my back.... So can only say what I have tested and that is the 240 is a little faster to the top of long hill then my 300( 1985 turbo). This is from a standing start. Lighter wieght, differant gearing, manuel trans all make a differance. Still the bottom line is it accelerates faster then the 300
