(no-ac) i have a hy turbo,stock air box. pushing 28-30 psi,will this overheat the eng up that much?will adding a pdr hx35 turbo with a cold air intake ,take care of this?how much boost can this eng handle without stressing the head gasket? see signature for truck info

thanks ken

What are your EGT's doing? That's what I would be concerned about. Your coolant temps seem about right for that grade. As long as temps stay stable, and you don't exceed 1200 pre-turbo, I wouldn't be concerned. You are giving your engine a good workout, but I see that as a good thing... how much load are you pulling? Oo. Guess I should have looked deeper into your sig... I just picked up a SandPiper Sport F37SP, picking it up at the Oregon boarder Wednesday... can hardly wait!

the banks kit limits the ex temp to 1200-1250 max. it tends to run 1100-1150. i push as hard as it will handle while keeping an eye on the temps. my load is approx. 11,000 lbs. ken

Sounds OK to me, maybe think of it as aerobics for your Cummins, just getting a good workout. Guess I can expect to see about the same with my SandPiper F37SP, find out next weekend.

Where is the thermocouple located?Is it pre or post turbo?If it is post turbo your egt's are way to high & driving up your water temp. What kind of boost are you getting with that baby turbo?

pre turbo, 28-30 psi

Those temps sound kind of high.



Check your radiator for oily residue in front of the fan blades (the circular area).



Alot of people have had plugged radiator fins due to dirt packing up w/ the oil residue greatly reducing airflow and cooling ability.



The residue coming from the stinking oil breather bottle of course.



This is becoming a common occurrence in our trucks, and its almost a must to relocate the bottle, or at least do something about it, before you have a oil/dirt caked motor.

already cleaned radiator and relocated bottle down just in front of the left frt tire.
