cardboard was destroyed quickly with no apparent fan slowing. I'm starting to think that the turbo installed may just be too small and that's why it's heating up at higher output.
This thought is frustrating especially in my situation, but in spite of what research I have done, I really have no one to blame but myself. I know some of you must be shaking your heads at my seat of pants approach to things like this. Even though I have a warranty for everything that was done, backtracking several days to try and convince "experts" of what I think (which is going to cost them money) sounds unlikely.
I'm considering the idea of trying to find a larger used turbo... I don't know. Using the skinny pedal in fifth sees raising coolant temps most times of the day here, and that's no fun. I'm already running 4.11s with an H55F so cruising speed is already low (fortunately it's usually about the speed of the traffic. Maybe insulating the intake pipe or attempting to find and add an intercooler will help?
Maybe I should just blow up my truck... (don't worry it wouldn't be a scam, I don't even have insurance!
