Newbie here. Question about increasing torque output. From all I have read about the 617 for it being a 3.0 liter turbo diesel it is weak on the torque side. I have a few questions. One is let's say on an intercooled setup what is the max boost pressure? Is 20-25 psi out of line? Should I drop the compression of 21:1 ? Or is the lack of torque a camshaft issue? I ask this because I have recently purchased a 404 unimog which came in the bed so either I build this or swap another engine . Is 350 lb-feet of torque possible?
