OM 612 270cdi G-Wagon Torque Monster build
OM 612 270cdi G-Wagon Torque Monster build
I have rebuilt a G Wagon with a 270cdi engine and 722.6 gearbox. Frame and body are now finished. The vehicle should become a daily driver with whom I can also pull trailers. Can smoke black but should not produce a solar eclipse!
Start is an Om612 with original 150 hp with 1.2 bar boost pressure GT2256v turbo and original air water intercooler.
My goal is to get over 200 horsepower (that would have to be about 260 HP on the engine) and a torque of about 500NM that starts in very low engine speeds.
I've already thought a few things about:
1. A Turbocharger with milled compressor wheel. but what?
them original GT2256V or GT2359v I have both but what should I do that gives me a good torque band and still promotes enough air at high engine speeds.
2. Intercooling on air-air with a largest possible cooler I get in the front. (Measurements at 10 degrees outside temperature have shown that
Charge air temperature after 10 seconds full load increases to about 60 degrees and even further - I think that is not optimal).
3rd EGR is closed and the swirl flaps I want to disassemble and close.
4. Change the charge pressure sensor to a 4 bar sensor to avoid any problems with pressure peaks.
5. The topic with the cp3 pump and the injectors does not want to tackle, because I want to test first how much I get out with sofwaremod turbo and intercooler --- or will it not be enough with the modifications.
I hope there are more that have something about the head broke and maybe already built something
I am open to suggestions that have already been tested and grateful
