I have spoken with a few companies, seems that the double vanos system is the problem in terms of adding a supercharger. I dont think the block material would hold back the engine from any serious mods. Rpms kill rotating assemblys, its the crank ,rod and pistons and fastners that are much more important in terms of holding up against higher hp. I have heard the M division hasent even gotten their hands on the N52 block to see what they can do with it. Im sure the mods will come in time, they usually do. I have contacted a few companies someover seas which the aftermarket is a bit better for these cars and a few have said a remap tune can yeild between 15-20 hp alone. Seems the Us and eur versions their is a 10hp difference. Some might be in the tuning.
