[W126 Coupe] Turbo/supercharger

[Jonathan]

I realize this, so should someone want to go through the process there's 
nothing I can do..but @ the same time I'm not just going to give them away.

I've got a fellow doing these who's been in the business for over 30 
years, he knows Mercedes cams and what kind of pressures they see etc, 
etc.. 

Dyno numbers will of course be forth coming!
