Ford OEM vs IPR high flow oil cooler

[Invasivore]

Has anyone compared the 2 different coolers? Anyone using the high flow IPR one?

The IPR high flow oil cooler is a poorly done product IMO. It uses larger coolant passages to avoid the cooler clogging issues but the consequence is that the coolant goes through the cooler too quickly for effective heat transference and it lets the oil run too hot. I highly recommend you stay away from this product.

I don't follow the thought that more coolant flow would make for hotter oil.

I think what Mitch is saying is in order for the larger coolant passages to work optimally, the coolant flow would have to be slowed down in order to have an effective heat transfer. But you don't want to slow coolant flow either. The larger passages decrease the overall surface area of the coolant which decreases the effectiveness of the oil cooler. I don't know if the oil passages have been modified, but if their size has also been increased then the issue is two-fold.

I also share his opinion of their high flow oil cooler and chose another route for my repairs.

You need the coolant to spend enough time in the oil cooler in order to absorb the heat from the oil. If it's flowing too quickly, it doesn't spend enough time absorbing the heat, therefore you have higher oil temps. (In heat exchanger terms, it's called dwell time or contact time.)

Did you use the high flow cooler?

Plus, if the coolant passages are larger then there must be fewer of them in the oil cooler (unless the overall size of the oil cooler was increased), so there would be less surface area to transfer heat.

Any info about Pure Diesel's Trusted Performance DFuser fuel/oil filter housing delete kit? Looks like an external oil cooler could be added to the filter set up.

I wouldn't use ANY external oil cooler EXCEPT the one from BulletProof Diesel... Oh wait! I AM running the external oil cooler from BPD! If you are going to go to all that effort, you may as well do it correctly.

Is there a factual comparison between the two or just hearsay?
