Is limited by the turbo, map sensor, just read 1.4xx bar if more, goes into protection, and high pressure pump is limited to a 1400bar + -, then injectors. Also hobbled by failures in the vacuum line and solenoid, and the light turns yellow chek engine. Then as you are also canceling the FAP, with a suppressor and fap override the heater.
Another thing we try to do, and I tried, is mounting the 6-speed gearbox of the 20MB04 c5 2.2 hdi 136 of the first. Much better with that box, the 5 speed is a bit shorter than the standard, but I do remember 6v 2000-2100 rpm at 120kmh. Very comfortable for highway and with the pair having the engine, well liked.
My mapper has had up to 190bhp out of the standard engine thanks. The limiting factor of the engine is the turbo at that sort of power.
I've fixed my vacuum problems slightly differently to how you show but its sorted. IMO the fuel pump will flow close to 1800bar although that is above its safe limits it just requires changing of the rail pressure sensor. Hope I can get a set of refurbished injectors at some point.
Id love to get an ML6 gearbox on, i need to dig out my old research on which has the longest ratios as it isnt the C5. i think i could probably drop the motorway cruising RPM a little bit.
