Hey Cerven,
I have about 60K on my 616 running a Garrett t-3 (.36 A/R turbine) with no problems whatsoever. 9-10 pounds of boost (it will go to about 14), 135bar injectors, 3.07 gears, and the IP is cranked up too. I do have an oil cooler off of a 300 which probably helps the pistons a bit and I don't run it at 100 mph for hours on end, but short high power blasts to get on the freeway happen daily.
Mileage runs between 32-34 at 70 mph with the automatic tranny or about 36 with the standard. Yes, I really have run the car with both transmissions, and it is definitly faster with the auto. I do not have accurate 0-60 times to report, but when I get my G- Tech I'll post them.

You really can turbo the 616 into a pretty good, reliable, fuel effiecent runner.

Just reporting my experience, yours may differ!
Cheers, Chris

Can you send me pics of your set up? What manifold did you run? I was thinking about modifying a 115 manifold. I want that center exhaust exit. Any info would be great.
Thanks

hint...hint...i have one for yah, check the link

Parting out 1981 300SD, good engine bad trans

its just more efficient to have an aneroid to control the inital overboost.

You probably mean initial lack of boost.

I don't use an aneroid and my MPG is no different without it.

ah i meant overfuel

Gotcha.

Anything i can do to up the performance mechanically? different rings? pistons? valves? head surfacing? porting? i mean nothing TOO deep but i mean something you can do or buy differently. but i want the same reliability of the original Mercedes part.

The OM616 when properly turbo charged by the factory like the one I have on my Gurkha is a percet balance, it develops 91bhp, good enough to push it even on a heavy vehicle like mine and returns and excellent 36mpg on hwy.

OH, I almost forgot.... Have your machine shop knurl your valve guides slightly if they will and go with a 3 angle valve job! These things I mentioned here will not only boost your preformance, but will also increase your fuel economy! REMEMBER! You DO NOT have to sacrifice fuel economy for performance in ANY engine if your build is done right! Pick up a book called "Smokey Yunick's power building secrets". Many of the mechanical recommendations pertain to both gas and DIESEL engines! You will learn a lot! Good Luck and show us the finished product!

The same guy that built a turbocharged Fiero and claimed it was not a down-draft carburated turbo gasser but a "hot-air-engine".

lol. fuel being dumped directly into the turbo. sounds healthy.

What this page doesn NOT tell you is this engine was designed for racing around a track at constant high RPM's! This design is very efficient for that, but would be lousy in the realities of day to day stop and go driving! This was for LeMan's or Monte Carlo style driving where output and power remain high at 3200 to 6000 RPM for hours! These engines don't idle very well and the fuel being dumped into the turbo once the engine is hot is NOT liquid, but vapor only! Know what you read! There are also a lot of engine designs by Smokey Yunick that deal with what you can do to your engine making it fit well into daily driving while maintaining good fuel economy! One of the things recommended is a 3 angle valve job. This will not only make your valves last longer but will increase compression as well over the long run, but know that REGULAR valve adjustments are Critical in vehicle performance and maintenance! Second, using gapless rings like Childs and Albert, Eropean parts designers for performance, will help to keep compression in your cylinders where it belongs! Note that Childs and Albert DO NOT offer Chrome piston rings, but get them your corrct bore size and they will get them to you. If you have the courage to get Smokey Yunick's power secrets and read it all the way through, you should become aware of how different engines that he built will fit different driving situations, but will NOT often cross over to other uses well. You have to use your own head and decide with the help of a GOOD machine shop how far your expectations and budget will go. His explanation of camshafts is well versed even to Chrysler engineers like me and this is where you should start. It is also the very first chapter of the book. Good Luck and keep us imformed of how it turns out and remember, my 1983 300D will do 0 to 65 MPH in under 10 seconds compared to the average 13 to 15? P.S. Gasoline engines with a carburetor will dump the fuel and air mixture directly into the turbo! Those turbos were designed for it! (You do realise your looking at a gas engine in this picture, right?

With a fast reading speedometer I'm sure you can do 0-60 in 10 seconds..........
