If you were stuck with swizzle sticks, you could tape a bunch of them together to get the same effect.

That 50 PSI is our pressure budget to work with. It will always end up at zero past the journals but they are not the only things that resist flow (drop pressure). They could be if there was a short fat pipe between pump and journals but that's only for imagination. Now start adding stuff like corners and narrow galleries to resist flow. If we feed the journals through a swizzle stick, the swizzle stick would take up most of that pressure budget because the cross sectional area of the swizzle stick hole is similar to the journal clearance. Let's say that the journals see only half of that total pressure - 25 psi. How could we get back to that fat pipe? We can add a bunch of swizzle sticks together. Now oil flows more easily through that part of the circuit. Less pressure drop because more cross-sectional area.

I chose to uninstall the sandwich plate. Plan going forward yearly is to uninstall in October and re-install in May when temps get above freezing consistently. The oil cooler itself and lines remain installed but tucked away, much easier this way

I have the same issue, it is even worse if you have a splitter and ducted hood. I left my house once in July for a track day at 4am and drove nearly 3 hours. It was a little over 50F and even my coolant temp Couldn't hit 160F

Even on my 13 row Perrin kit (Setrab 613), my highway oil temps were below 170 F when it was cold out. I've mounted my front license plate as a block-off plate and it works fairly decently. I just pull the front plate off at the track or in the canyons.
At the track, the 13 row is what I'd call barely sufficient for NA. I would hit occasional peaks of 240-245 F. My suggestion would be to get the 19 row and create a block-off plate for the highway.

Have you considered that you might not need an oil cooler?

I also used the oem forester water to oil heat exchanger, both of these combined let the oil warm up to 170s fairly quickly regardless of weather. Also unless relocated the sensor is post oil cooler, and the oil could be a solid 30F hotter in other parts of the engine / pre oil cooler. |
