That is false information. Please look up the C111-IId and III and you will see why. I trust MB's engineers know far more than somebody in their garage with a saw and welder.

Recognize that manifold? MB felt it was good enough to make a continuous 230hp.


You are vastly over-thinking the intake and you'll see no measurable benefits from all your work that an additional 1psi of boost, an intercooler or water injection wouldn't outdo.
