I have a Koyo rad and stock oil pan with a stage 2 protune. I have seen up to ~270 oil temps in the block in 90* ambient temps, so things can get too hot even with stock turbo. In 50-70 ambient temps I usually don't see above 255* oil temps.
I agree. I didn't mean to stuff it in the sand when it hits red

My car is at the track once a month for the past 3 years, circuit, autox, rallyx. Stock oil pan & pickup, koyo OEM replacement radiator, no oil cooler and a stock STi size turbo running 20psi. I did have a GS AOS but it was useless at the track so I now have a dual catch can setup.

I would suggest a very conservative tune for the track unless you are running race gas.
Plan to dial tune back for the track (richer, and less boost)

running a richer tune will cool things a bit better, and you can run straight water with water wetter to make your radiator cool things better too. so yes, if you lowered the boost a tad that will give you a safety buffer.

a killer bee pickup, oil cooler, good brake fluid and good brake pads are the 4 bare minimums for track work (assuming your car is totally stock) IMO. also assuming you're running quality oils/fluids everywhere else at their maximum levels.

heat wrapping the headers and dump will do wonders for underbonnet temps.
will look into wrapping headers/dp

c. buy oil temp and oil pressure gauges and pull off if things get too hot
d. install good brake pads and let her eat

Other notes: I'm trying to keep this apples to apples with Stage 1 and 2 GRs, as GDs have different radiators, airflow, etc.

AX and RR are WAY different!

Experience-wise I've got about 90 track days and was last running in instructor group before I sold my other track car.

Brakes---separate topic (understand I need to do fluids/pads and possibly LGT upgrade)

I just want to focus on the oil temps/cooling/etc for now.

My goal is to not use an oil cooler (rather get by with Koyo and KillerB pan), but if that is not going to do enough, maybe I would do just the KillerB pickup/baffle and oil cooler and skip the pan, and possibly the Koyo.

If for ultra-reliability I have to, I'll do Koyo/KillerB/oil cooler and not worry about it. Was just trying to avoid the plumbing of an oil cooler on a mostly street car.

I'd say go out on your first track day of the year with just a fresh oil change and a gauge and log your temps. Don't take it to 10/10 right away, work your way up thru the sessions and go from there. My 2cents.

Hey Tony,

I saw 260+ deg F with OEM turbo, really depends on how you drive. My guess is that if you are new to track driving, and you have the Oil pan, then my suggestion would be put a temp guage in, and see what happens. Anything more than 250 deg F and you probably want to be ordering the bit you will need fotr a cooler...

Yep. How you drive and ambient temps will have a big effect.

This is what I did:

I would recommend an Oil cooler;

My car is a 2010 Wrx with Cobb OTS stage 2+AEM, Crawford AOS, stock intercooler and radiator.

I was getting up to 275-280 on the track with 20 min sessions. Granted I'm in Texas but I was avoiding Summer events for this reason. Luckily I was using Motul 10 W40.

I believe our cars cool differently than STIs and even other WRX and are more susceptible from the factory. Something about not using the radiator to cool the oil.

This is what my set up looks like. I've only run it while it was cold out but it stayed at ~235.



Only other issue I had was with overboosting going about 125 down the back straight of COTA when it was cold out. Oh and brakes, you do need better brakes.

^ What size is your core...? And do you use a thermostatic sandwich plate...?

I forget exactly what size, but its a Mocal unit, ~$400. Yeah I have the thermostat sandwich adapter, so the oil gets up to temp before running through the cooler. The entire shebang instaled was about $900.

Nice job! Any before/after temp results? Also do you have any more pictures of your radiator shrouding? Any idea how much that improved your coolant temps on track?

That looks like its probably a 19 or 25 row mocal. It looks like about 50% of it is blocked by the bumper. I'm shocked that it only got you down to ~235 in COLD weather (what is considered cold in Tx)? What is the oil temp with cooler in hot weather (80-100F)?

Haven't done a track day with it in the hot, I think it was around 55 deg F when it was geting to 235, but considering normal operating temp before the cooler was around 220 I'm happy enough with it.

Will definitely be interested to see how it handles the summer though.

I'll eventually mount it somewhere else when intercooler shenanigans happen. Though I was warned against setting it up as a top mount like I wanted since oil spraying onto the turbo/downpipe = no bueno.

+1 for nice setup, very cool... Dig the brake ducts as well, which ones did you go with?

I would recommend guages and some track time before going in any direction. Nothing worse than spending money on parts that aren't needed when you could be buying things to make you go faster

If temps are good, then great, buy other stuff!

If they are borderline, a high capacity pan will drop them enough to not be.

If they are HOT, there is no substitute for a cooler and thermostat setup. This is most often than not needed when the car/driver is beyond the enthusiast level of track events.

After reading all of this, I'm likely going to get the guage, the killerbee setup and do my own oil cooler. I figure I'd be doing the pickup and baffle anyway, then the temp sensor can be in the pan. I'll monitor temps with the pan only on the street, then likely add the cooler before hitting the track. I also plan to do some radiator shrouding like Josh did in the pictures above.
