Good stuff. Thanks!

I just finished a track day at the Ridge. This was my first time with this car at this track, and I need to get used to it, but it was overall not bad at all. The car performed great even though the oil temps sky-rocketed (more on that later):


If you can read, the oil temp gauge is on the left in front of the shifter. It starts at around 292 degrees F by the start of this lap, and ends at 297 degrees F (by the end of 10th lap). In short, the car is overheating.I am honestly not sure what's going on at this point. The oil cooler is simply not adequate. Does it not have enough air flow? I am also wondering if a different style of core would help more?

Anyhow, perhaps I should indeed seriously consider my idea of installing the OEM cooler back, and converting the auxiliary oil cooler to get it from a sandwich plate adapter. This way, I can also get the help of the radiator to cool down the oil, which is under-taxed at this point. The temps were around 75 degrees max. I am disappointed in this.

I added more water to the coolant, so it should be about 30/70 right now. I am wondering if the lower coolant temps can help reign in the oil temps. I honestly don't think so, but it is very easy to try : )

What cooler are you running? Is this it?

If the dimensions are accurate then I think it's too small.
After reading this I'm worried I may need a cooler that is as wide as my radiator. I suppose if I space it up slightly I could manage that but I don't know anyone who makes a single cooler that wide.

Stock cooler is a step back. Cooling 290 degree oil with 220 degree fluid versus 290 degree oil with 80 degree air, it's just a matter of surface area now.

I'm using this one:

I'm thinking about replacing it with this one:

I'm also wondering if the 90-degree rotated orientation is causing me issues. As you can see, the ports are at the side, not at the top:


This 48-row series 9 cooler I referenced above has a much higher cooling capacity, and would fit where I installed, but some part of it might be blocked by the crash beam, and I wonder if it would impede its performance.

HP range Part Number Width (in) Height (in) ∆P (psi) btu/hr range
600+ 50-172-7612 8.27 22.13 0.8/1.0 40,000-60,000
600+ 50-948-7612 15.94 14.70 1.8/3.1 69,000-96,000

Looks like it has 50% more capacity. What do you think? I am really speechless about the amount of cooling I need.

When I mentioned the OEM cooler, I meant to use it in tandem with my aftermarket cooler. I did that on my supercharged Miata, and it finally kept the oil temps around 270 (which creeps to low 280s by the end of a 45 minute session; acceptable).

The core I referenced (Setrab series 9, 48 row) is actually almost exactly double the capacity of those oil cooler cores, so it might actually work. However, the location he's used might be better.

With that inlet arrangement I have to wonder if it's short circuiting the cooler and you're only getting maybe 25% of the cooler being used.

Ignoring gravity, the oil will go through every available direction with the same speed and pressure. This message it will short circuit a bit, but not too much.

The other core's ports are up top, and far away from each other, which should help.

[Synner]

Everything I've learned and designed says the opposite in air and fluid systems. Especially in one that long. The existing fluid (or air) will be at the same pressure but act as a road block for the new fluid coming into the system.

Following that logic, this oil cooler core should short-circuit even if it was put vertical, Setrab's intended orientation, right?

I'll talk to Improved Racing and see if I can convert my system to that 48 row series 9 unit. I don't even want to touch anything but the unit, so I'll just extend the existing hoses with a lock fitting or AN, and install that new core. My main question at this point is the location. If I install in the current location, a part of the cooler core might be blocked. It would be best if I closely stack it in front of the A/C condenser, but I'm still not sure how.

[Synner]

Yes orientation won't matter. Unless it has internal baffles that force it to use the whole core, like a 2 or 3 pass radiator, you get at most 50% efficiency.

I'm hoping Setrab thought about it and made it work.

Wow. Too bad about the tire issue and that the oil temp issues are still there. Car looks great though and really great upgrade choices. I couldn't tell in the video, did you get a chance to run the Schroth belts?

Yep, and they work! I even used my HANS device with them, and I think Recaros + Schroth belts is an acceptable solution

At this point, my focus is at the oil temps. I want to get this thing fixed one way or another!
