Forrester Oil cooler

[OrangeGuitar]

Bone stock is fine for DD in terms of heat dissipation. Not sure what laughable means - the Forester plate does help with stabilization and does lower temps significantly on track and when running over 4K extended vs bone stock. That has been my experience and that of others but maybe you had different experience with it installed. The stock radiator is quite effective for NA. A full oil cooler will of course do more especially with FI. It will have more oil to heat on cold mornings in DD too.

I run one, street and lots of track. I have mine on a separate coolant loop with its own dedicated "radiator" and water pump. Works fantastic.

Could you share some pics of your setup, that sounds like a solution that cuts no corners.

I thought about doing something like this a while back. So many questions Pics of your setup would be appreciated. Temp. data too.

I've had it for years. I had everything from excel spreadsheets to line graphs on the improvement I logged but that laptop got stolen. I'll give you a rough outline from memory. I'll get pics when I have the chance.

It has a heater core out of a mid 80s crown vic mounted in the front passenger fog light grill (I cut it out and installed black wire mesh) I also cut a hole in the fender liner to give the airflow somewhere to go.

It uses a Bosch electric coolant pump out a 2004 ford mustang cobra (supercharged).

I used a power steering reservoir to hold the coolant / give a fill point. I just used heater hose to connect everything.

On a 30 degree (c) day i went from 270(f)+ oil temps at our local track to mid 230s running it very hard behind another car with the cooler on. My oil pressure still wasnt where i wanted it though so i ended up switching to 5w30. Sorry for switching units. Our track is pretty low speed so airflow is minimal. Highest speed I see is 160k/h on the back straight. On a higher speed course or with a front splitter I can see the added airflow making a larger improvement but I see 230 degree oil temps as more than acceptable for a good quality oil. I decided the problem was solved and shifted my focus elsewhere.

Oh, and I'm NA.

Sorry to bump an old thread but do you have any pics of this setup? It sounds like an awesome idea.

I'll second this. Pics and part numbers for that pump please.

There's like 1000

Thanks. It isn't just the coolant pump that I am interested in but rather the entire setup. This is an awesome idea because:

- You don't run the risk of oil leak or worst, blowing an oil line leading to catastrophic failure. Worse can happen is you have coolant leaks and run out of coolant, effectively no oil cooler. But factory oiling is retained with no chance of failure.
- You can wire an switch to the pump effectively turning the cooler on/off pending condition. Therefore, you can bypass over cooling for daily applications.

I suspect the power steering reservoir must be the highest point in the system in order to run an air free system? Essentially, you are building a liquid cooler that is found in gaming PCs these days.

Yes, so much yes. I would much prefer this as well, but how feasible would a system like this be, especially in a track application. You'd think we'd have seen something like this already.

I agree hence I wanted more info about the setup. The poster of the idea claims that his oil temp went from 270f -> 230f after this install. I think it's believable because the coolant that is going through the factory coolant/oil exchanger will be ambient (95f on a hot day). I think one of the limiting factor to the using engine coolant is that it starts off already @ 194f hence there is only so much heat it can extract. But if you are talking about ambient, I can see the effects being far greater.
