OM617 Performance
OM617 Performance
If you want a 617a tuning baseline look at the threads titled "C111", I think they are stickies. Essentially, what they had was a long-runner intake manifold, a big turbo with intercooler, large free-flowing exhaust, and a custom IP. Granted, that car was designed for one thing only: a specific power output at a specific rpm in order to set long-distance speed records. However, just by looking at it you can see how crude and easily replicable the induction tract was...
Here's your recipe for something marginally better than the C111:
(1) custom tubular exhaust manifold
(2) W115 300D long runner intake manifold with integrated A/W IC
(3) modified injection pump
(4) 3" exhaust
All of these things must be manufactured by you, because there is no one else to do it. Do you see yet why there is no "baseline" as you describe?
Just follow "first principles" of fluid dynamics with respect to the airflow and provided you have read your turbo map correctly you will be all set. Its the turbo map which dictates all the performance characteristics.
The limitation is still the fact that the OM617 simply cannot flow enough air efficiently to make lots of power.
There was apparently one that made 340hp or so but apparently it grenaded under (lots of) boost. Others have been claimed around 300hp. The C111 was something like 230hp.
