I contacted full race about there IC and they said moving it makes it a better design. I live in ohio and dont plan on towing that much, I didnt put this truck to tow stuff with.
I trust full race, they make great products. The manifolds they make are best in the industry
It is a better design, for the intercooler. When Ford spec’d the entire cooling system, including engine and transmission oil, they made some assumptions with total cross section, weight, grade, ambient temperature, speed etc. If they said it can tow 8,000 pounds then they surely took the truck out to the desert and hauled such loads up and down grades during the searing summer heat and carefully monitored all those temperatures. If during those tests the ambient temp was 116° that day then THAT is what each heat exchanger had entering before it was expected to cool its associated component. Turbo discharge temps can soar up to nearly 200 degrees under continuous load, more boost increases exhaust which spins the turbo faster which increases the inlet temperature. This increases would continue until detonation took over and the entire engine let go. The intercooler is of such size to maintain the air intake charge at a stable value vs increasing. That being said, even in a stable system, the discharge air from the intercooler will be hot, maybe even average out to 140-150° across the unit. NOW your cooling systems are working with 140-150° cooling air vs the 116° we spoke of earlier. It is possible with enough frontal cross section (horsepower offsetting drag) that enough boost is required to exceed the cooling capacity of the engine oil, transmission or the cooling system in general.
Unless Full Race installed their kit and tested the cooling capacity under the conditions Ford did then it is simply not an entirely accurate statement on their part. Improved in the sense of more cooling area, lower intake temperatures and good enough for 95% of us that don’t “work” these things up grades in searing Summer heat? Yes. For those of us working these things we just won’t know until you try, you have an untested platform at that point.
I have towed my 9,500# boat up 6% grades in 100F at 74 mph with A LOT of boost for durations that lasting nearly five minutes and NOTHING changed on any of the gauges. But I had 100° cooling air entering the engine compartment, not 140-150° air.
Caveat: I don’t have an oil temperature gauge.
