Hi all, planning an OM606 compound build, with the aim of daily driveability while keeping top end power. I see many people have built compound setups, usually using an HX35 as the small turbo and HX40/50/55 as the larger turbo. I am considering a smaller turbo, perhaps an HX30 or HX27 for a much lower boost threshold. 
Can anybody give me an idea of what RPM I can expect to see usable boost with an HX30 or HX27 compared to an HX35? Also, would the HX30/27 compressor housing be too restrictive up high? 

The alternative is to supercharge and single turbo. Has anybody had good results with the like of a big Eaton? Or would you expect this to increase fuel consumption on the highway greatly?


Thanks, Jack.
