I doubt they lowered compression. Lowering the compression would drop power and efficiency. I know someone with an 82 300SD that has run 26PSI of boost for 30+ seconds up a hill (intercooler and a modified stock turbo). The OM617 can take the increased boost.
Another reason I'm sure they didn't lower the compression is they were going for a near stock production engine record. I'm sure playing with the compression ratio would have made them ineligible for this record.
From the picture we can see they have done the following.
1. Used a 76' W115 300D intake manifold (tuned runners = good ).
2. Put a big ass turbo on it.
3. Put a big ass intercooler on it.
4. No EGR....
I'm sure they turned up the fuel and tweeked the injector pump too.
