It sounds like heat did the damage.The advantage is a couple horsepower and lb ft torque under load at high rpm. The disadvantage,as stated is the time and money needed to put the turbo on will likely never be returned in work performed. I did this last winter and found I could push through a sidewalk plowing, that I couldn't without the turbo. What did that save me, about 30 seconds a run. I pulled the turbo this spring ,as it was getting a bit loose and was putting a bit of oil into the intake tube. (chinese turbo)
No, I figured you knew that much.I should cear up my "deisels love air" statement before it bites me in the butt. Deisels love COOL air. As you add boost and compress the air it gets hotter. I imagine this is what you were talking about as far as air causing dammage in a diesel engine. That point is well taken, but again, 2-3 lbs boost doesn't build much heat in the winter.
No, boost is not based on fuel.Skwirl, I still don't get your point. Isn't the amount of boost a product of the amount of fuel introduced into a turbocharged engine? If you have no fuel,you have no boost. You cannot compare the failure in one cylinder to a complete engine assembly.
