Ordered the smaller setrab unit with fan to replace the oil cooler that was installed when I bought the car (pictures). The new setrab unit is way smaller than I thought it would be. In fact, it's about half the size of what's installed now. I'm pretty sure the bigger setrab unit with the double fans is too big for this space. Anyone see issues if I run two of these smaller units in series? That way I can install them staggered and will fit in that space quite nicely.

Oil cooling works best when there is a large differential between the oil temp and the air temp. So the first cooler, with the hottest oil, will drop more temp, and the second cooler will be underperforming. Coolers in parallel will keep the differential high and will slow down the oil so it will Cool down more.
Plus, that path of least resistance thing is a little too idealistic. Yes, one will probably have more flow than the other, but I expect its negligible since the resistance to flow is fairly equal. It's like taking a garden hose, hooking up a y-adapter, and expecting that the flow between the two nozzles will be drastically different. |
