Anyone Supercharged the OM617.9XX Engine
Anyone Supercharged the OM617.9XX Engine
Anyone out there supercharged the OM617.9XX N/A Engine (The non-turbo version) ?
Any info would be super appreciated -- EG Heat generated by supercharger, et cet. The NA version had the "M" pump (I think).
Post your thoughts please.
Thanks !

Project 2018: Really get the car finished -- Turbo OM617 greater than 175 MPH goal.
RED W123 - left Germany as 240D in 1982. Full AMG body kit less rear apron, 2:65LSD, five speed Getrag 717.400, manual steering, read leather interior, manual brake conversion, electric water pump (EWP), and a bunch of other goodies ...

If I were to do another one, I would definitely intercool it and put a bypass valve in it to regulate boost to throttle demand.
I am not a turbo fan at all, but that is based on my experience with them on gas engines, where I like the blower for better. Having the VNT turbo on the 616 now, I must say that IMOP, a properly sized turbo is best pared with the diesel engine.
I put a M90 on my 616 a couple of years ago. Took if off after about 1 week lol. Too much noise.

Did you notice anything negative or adverse ? (excluding noise)
Any perfomance to speak of ?
Do you think it would produce too much heat for the NA engine ?

I agree with OM616, turbos are best. They have a huge thermodynamic advantage over superchargers in that they harness waste heat that would normally go straight out of the exhaust. The only exception would be cases where the platform has serious gearing issues, like a wide ratio 3 speed manual trans.

OM617.9X N/A engine which I know is more of a pain in the butt to convert to a diesel engine than what its worth vs. just getting a turbo engine. I have a mod'd M pump so I got plenty of fuel. Just looking to see if getting a Vortech SC would be worth it, in that
1. Will it work ,eg., not destroy the engine
2. Will it provide some performance or just be a waste
Please weigh in because I might be stumbling into a NA engine shortly and my real project might be delayed. Thanks.

Let me give some more information.

So yeah, just watch your egts and you're fine assuming you have more fuel.
Personally I'd rob the manifolds & m-pump and build up a turbo motor

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
Simpler=Better
