Ptunning Oil Cooler or just get the Jackson Racing

IMO there's no reason not to run 5w30 if you're going to be tracking it.

From reading your posts it looks like you have a lot of track time. Any thoughts on the oil to water setups?

From this data it looks like with 5w30 and no oil cooler, oil temps get up to ~275F and pressure is ~7.5 psi/1000rpm.

WITH an oil cooler and 5w30 oil, temps are down around 250F, but pressure is still ~7.5psi/1000rpm.

Theory: increase in pressure from cooler oil is exactly negated by the pressure drop from the cooler itself, maybe?

Anyway, I haven't seen any evidence that I *need* an oil cooler for my track usage, so for me, IMO it's not worth the cost/effort/risk of having one installed.

A forum post backed up with hard data, you sir are outstanding.

Good info.

Jackson Racing or Greddy.

I don't know why you wouldn't run a cooler for track. I installed mine this pat winter.

Because apparently a couple of hundreds and an hour or two to install a sandwich plate and a couple of lines is too much work and risks involved and people would rather throw a new engine in for a couple thousands every couple of years. Why else would it be, right?

If I blow up my engine maybe I don't have to go in for the valve spring recall...

Looking at 2nd plot, if my oil temp steadily climbed to 280F during a track session without stabilizing, I would definitely consider an oil cooler. My oil temp consistently goes up to just over 270F and then holds, every event, every session. In my case the oil temperature is under control and not trying to "run away", and in my judgement 275F is not unreasonable for 5w30 synthetic in this car for my usage (~12 track days per year, ~4 15-min. sessions per day).

I don't think not running an oil cooler for limited track usage equates to needing a new engine every couple of years...
I don't think an oil cooler is a bad idea for casual track usage, I just don't think it's necessarily a requirement.

Casual track days? Probably not worth the risk considering it's another point of failure.

Also if your engine fails with an oil cooler, Subaru won't warranty it. Maybe you're able to carefully remove the oil cooler, so it looks like it was never there in the first place.

If your engine is STOCK and doesn't have an oil cooler, you have a better chance of Subaru covering it under warranty.

I could get 7 laps in on a short track and my oil would start climbing past 250F. That was enough for me to pit and cool down. I was toast anyways but that's besides the point lol

I would not want my oil at 275F but to each his own.

From another oil cooler thread in which I go on a bit...
http://www.ft86club.com/forums/showt...+cooler&page=2
FWIW here's how Ford characterizes oil temperatures in '18 Mustang Factory Service Manual:
38-60° C (100-140° F) (low)
61-137° C (142-279° F) (normal)
138-146° C (279-295° F) (warm)
147-160° C (297-320° F) (hot)

[new2subaru]

I'll keep that in mind if I ever buy a Mustang


JK, like I said to each his own. I'd rather have my oil temps on the lower side.

People who do autocross in street class (like me), can't install an oil cooler because of the rules. It's a stupid rule, but it is what it is.
