Default intercooler relocation

has anyone ever moved their intercooler or would see it as a bad idea to? on my chevy with the ac condenser intercooler and radiator all there, it gets HORRIBLE air flow through there (keep in mind it wasnt designed for this appliation. ive been thinking alot lately about plumbing the intercooler underneath the bed so that i can run a much larger radiator and electric fan setup (in california 110 degree weather pullin a trailer it just doesnt cut it)

can anyone see any reasons as to why this wouldnt work?

Wouldn't that create more time from the turbo comp to in intake manifold? I suppose a badass enough turbo may not make a diff though. What about cutting some holes in the bumper? Or maybe running some ducts to the aftercooler?

im not worried about a little more turbo lag ill worry about that later. and im ot needing duct or anything for the intercooler its not that im worried about. im trying to get more air to my radiator it gets horrible flow. the intercooler and ac condensor stop any air from actually gettin to the radiator

for the air to air I think the shorter you can keep the piping the better

I'm wondering why you don't get good airflow to the radiator. I mean, they are designed to be flow-through parts. The net cooling effect is reduced only when the turbo is boosting and the A/C is on, so the air is a bit warmer by the time it gets to the rad, thus a little less heat transfer potential. But that should not make a big enough difference to really be even noticeable, except possibly under extreme conditions like towing in the summer.

Is the truck running warm or overheating?

Don't the Chevy Diesels have holes in the bumper for cooling like the Powerstrokes ? If so that would probably be helpful

in the mornings when its only 80 degrees outside or so it runs right at 180 on the money all morning long. but when i get off work and its 100-110* outside with the ac on it runs at like 220 without any load on it. going up a grade even without a load it will climb from there and i definitely need to be able to tow a trailer in summer time. my electric fan is millimeters away from my belts i have no room for anything under there and i would like to go back to the chevy radiator (its like 43" wide by 19" tall and cools much more efficiently IMO) and with the wider radiator and more fan clearance with the intercooler gone, i could go back to a killer dual electric fan that would work much better than the one fan but i dont have room right now with the skinny little dodge radiator to fit a 2nd fan

I would confirm condition of the thermostat, water pump, fan clutch and the rad itself before assuming airflow was the problem.
