Oil Cooler Woes? An FYI

@brillo and I have known about this for a while. The Mocal Thermostatic Sandwich plate used in many oil cooler kits, including my homebrew one, can sit very close to this metal line. I'm pretty sure its a fuel line for the port injectors.

It really depends on how you install it, but the OEM airbox as well as the Vortech airbox can make this sandwich plate make contact with the line.
[This is an example of how it hits, I took this picture after I modified the plate]

@brillo took action immediately but I decided to wait. Three months, 4800 mi, and two track weekends later I get this

@brillo contacted Racer Parts WHolesale and Mocal and they say its fine to file down the edge of the thermostat. He did and didn't have problem s yet, so its my turn. I basically filed it down so its close to even with the plate itself

After it is all said and done, there is a little bit more wiggle room. If i keep turning it CCW, the plate will still hit the line, but in a different place. Thankfully the oil cap keeps me from turning it more. I think a true solution is to reroute the oil cooler lines (I have something in mind) or to create a larger spacer to raise the sandwich plate higher. I'm not sure if kits like the Perrin have a larger sandwich plate.

Any ideas?

Here is 45 degree barbs on my Vortech kit. I think I can make the 90 degree barb clear.

Here is the same thing on the stock Airbox. I don't think there is room for 90 degree barbs to go straight out and down.

I'm open to ideas!

I have clearance over the fuel line with the mocal plate filed down. I'm going to take it off soon to double check there is no contact or rubbing but I check the clearance every so often with a piece of paper to see if it will slide between the two components without issue. If you have a CAI you won't have any issues (I am using the stock airbox) as you can rotate the plate and the lines away from the lines.

So I finally got the FR-S out on a track to get a sense of the cars oil temps under moderate stress. The temps outside were mid 70s with humidity and the track was relatively short (1.3 miles) so not alot of long straights.

I was 6 to 7/10ths most of the time with occational spurts to 8/10ths as I was shaking off alot of rust. Most of my sessions were 6-8 laps depending on how my tires were feeling (I was being a bit conservative being my first time out in a while).

That all said, my oil (0W-20) got up temps of ~225 degrees towards the end of each run. Never saw it go above 230. As my driving skills improve and I run the car harder I could see getting close to 250 degrees in hotter but if thats my worse case I'm pretty happy all things considered. I'd say the cooler has me covered for the type of driving I'm likely to do.

Another novice driver with our club who was running the car pretty hard in NA form without an oil cooler was seeing ~250 degrees when he backed off after 6-8 laps to be safe. He is also running e85 so his engine was likely generating more heat than mine.

@F1point4 was this track data done with stock radiator?

Yes, and with stock coolant. Still running the stock radiator.

Very nice set up. I like the piece it together route you took.

Out of curiosity, has anyone considered running their oil cooler behind the bumper to the driver side. I was thinking of placing it there and cutting out the fake plastic mesh grill below the turn signals and cutting slits in the fender liner for air to pass through.

Wondering if the space there would provide enough air passage to be an effective mounting solution in case someone has a larger front mount intercooler.

Well I was going to build my own, but @Maximal did the work for me and cheaper than I could source the parts.

Tj, I considered trying to mount one their, but I have a BRZ with fogs so decided to just go with the conventional spot up front until I go FI in the far future.

Just trying to gauge if my stock radiator is going to behave like yours where it dances with 220 F temps or like swift's where it stays at 200 F even with 260-280F oil temps.
