Question to the mechanically inclined and beyond. It's a known fact that 3.0L M52 and M54 are heavier than 3.0L N52 since the latter is a newer better design using lighter elements including Aluminum. If moving parts also comprise lighter elements than less force should be required (from SC) to generate the same boost. Doesn't weight factor in favorably to boost assuming the N52 engine components withstand the added stress
