I'm not suggesting the W2O cooler is made for serious track duty.

Unquestionably better than not having it at all. Just another case of using race parts, because racecar, but that doesn't stop the aftermarket from selling them. Done.

As CSG Mike said, there is just not enough surface area. It would be like wearing a plastic track suit on a 95 degree day when running and holding an ice cold water bottle in your hands and expecting to feel cooled down enough to continue your run.

Ive already installed the factory oil cooler, and I believe it does help to get my oil up to temp and in control for my aggressive NA driving, but I will be getting this setup when I install the Harrop SC. I like that it upgrades the radiator and adds water to air oil cooling in a simple package.

My desire to leave the factory oil cooler in place is to have that extra oil warming and so there is one less thing to remove and sell at a loss. If they both can fit then I would like to keep them both.

Something like this would be nice. I did see that someone on here retrofitted a WRX A2O cooler with the Forester cooler, but it wasn't thermostatic. Which kind of defeats the purpose. But this cooler would be nicely pair with the Forester.

The purpose of the of the heat exchanger is to cool the oil. Hence, the term "oil cooler".

Like I said, if you want to heat your oil get a pre-heater. That's 100% more effective. Nothing wrong with installing a pre-heater in a sports car either if it's daily driven during the winter (nice comfort item too).

1) Otherwise, it's totally unnecessary. As I started out writing we are using modern multi grade oil that is perfectly capable of lubricating at lower temp.

2) With regards to oil and water... oil doesn't break down because of condensation. And it will evaporate next time the engine is running anyway. Oil degrades due to too high temp.

3) Next, if people want to heat the oil faster so it takes less time before they can beat on the engine, then that is a false logic too. The oil temp doesn't matter for wheter you can beat on the engine or not as the oil is perfectly capable at lubricating at lower temps (see 1.).

The whole engine needs to be up to temp. Block, pistons, rings etc. so that is has expanded to the designed tollerances. Having 4 or even 20 deg higher oil temp is not going to aid (much at all) in that.

When you say preheater do you mean a block heater, right, not a heat exchanger rig? Something that screws into the block and has an electrical heating element that warms the block used primarily in areas with snow/cold weather?

I commute 3.5 miles to work so extra heating of the oil is nice to get it to operating temp faster. If I was to get on it when it is cold to redline my oil pressure gauge looks like the pressure is going to go off the max value, and the few times I’ve done it I backed off. I can’t imagine that is good. There has to be a range of good presures.

I agree. For cool-weather, light-duty tracking and spirted driving in moderate climate conditions, or for those using ethanol maybe, the factory XT cooler would probably be sufficient. Add FI to that same mix or serious tracking and something beyond the XT cooler is needed for sure.

There's no such thing as "occasional" or "light duty" tracking unless you mean parade laps. A noob can put more heat into the oil than a pro in the same 20 minute session.

Sorry, when I said tracking, I meant racing, in the very general sense including autox, quarter mile, rolling mile races, etc. and I suppose there is spirited driving at the track too, but that isn’t racing, yet would be on the list of light-duty track activities.

I was actually thinking more of something like this:
https://www.webasto-group.com/en/ori...l-fuel-heaters

I have one of those in my 4x4 and is really nice on a snowy morning. Starts by using a timer or remote control. 20 mins later the whole car is nice and warm. It heats the coolant and circulates it through the block and HVAC. So not just the engine is warm, cabin too and windows defrosted. These are available in sizes that fits the FT86 (available from dealers here).

If you only commute 3.5 miles it's a bad solution though as the engine should be run same amount of time the pre-heater was running (battery). Something electrical you plug in would probably be better. I think Webasto makes something like that too. Did investigate how they work.

Yea, sweet product but like you said, overkill for me and for where I live.

Just noticed you're also in Santa Rosa Irace86.2.0! Yeah the handful of days a year when it barely touches freezing definitely doesn't warrant a heater. I got the DROC without concern of overcooling and in preparation for tracking and a supercharger in the future. I think your plan is fine as far as using the OEM one for now and adding the DROC once you boost. You don't do full 20-minute track sessions do you? I would probably recommend upgrading sooner rather than later if you do, I saw some pretty high oil temps with my last BRZ when I took it to Thunderhill even in winter.

I agree, plus my car is in a garage. I wouldn’t need a block heater for the traditional use of warming the coolant, so the coolant doesn’t freeze or so the oil doesn’t get so thick startup is dangerous.

I haven’t done really any track days just autox a few times. The plan is to get more into it when I get my kit, not because I’m trying to win, or anything, but just because I want a complete setup when I finally go.

So my car was garaged when I left this morning so it wasn’t as cold as the cars outside, but it was in the low 50’s this morning around 7am. My car idles for 30 seconds before I usually take off from the garage. I have the recommended 0-10 oil in there with about 3500 miles on the oil. In first and second gear the oil pressure was around 135 at 5500 rpms. My Defi gauge only goes to 140 psi. One to two minutes into the drive and the same rpms got only 100-110 psi. Three to five minutes in, and it dropped significantly more. I could imagine the psi going right off the gauge if my car was outside in the middle of winter or had thicker viscosity oil... and I’m in warm California. I never tested when I didn’t have the Forester XT cooler because I didn’t have my gauge, but I feel like warming the oil quickly would be important for some.

just went for a track day last weekend in Michigan (grattan raceway), my car has jackson racing dual oil cooler and supercharger, jr factory tune.
outside temp was about 65 degree, 20 mins session. oil temp max out 248F, most of the time stay at around 235F, water temp stay at 212F for the whole seesion. oil and water temp was read via OBD II.

That oil pressure seems excessively high. Is the guage reading correctly
