Real-time Oil temperature Analysis - Pre/Post Coolant Loop Oil Cooler Install
 

Hi all,

We recently installed the Forged Performance Australia OEM style coolant loop oil cooler kit in to the Project BRZ. The oil cooler retains a stock engine bay look (the cooler itself is the same as is used on selected factory turbocharged Subaru engines, such as the MY14 Subaru Forester XT), and taps in to the coolant system on the car and uses it to two advantages...

Brings the oil up to operating temperature faster.
Reduces maximum oil temperatures and transient spikes in oil temperature.
I've recorded a real time analysis with visual overlay under cold start, and spirited driving conditions for both pre and post install, so you can see exactly what the difference is between the stock engine with and without the cooler fitted.

Quick Summary....

Without forced induction and under normal everyday driving conditions at moderate ambient temperatures, an oil cooler isn't really required, however this cooler does still offer the benefit of bringing the engine oil up to operating temperature twice as quickly as without.

Under spirited driving or track conditions, this cooler has the added advantage of significantly reducing the maximum oil temperatures, and transient spikes in temperature.

Looking forward to install video. Seems a lot less complicated compared to this: http://www.ft86club.com/forums/showthread.php?t=50427

Took 20 mins to install including an oil flush and change.

There doesn't seem to be any info on the cooler on their site. Would you mind posting some photos of it OP?

i went to their facebook store. second from the top, listed at $450.

20 minute install? Where is this tapping to be that quick, throttle body?

I looked at their picture, but you can't see where the lines are running to. I'd also like to know, I like easier installs when possible :D

I originally wanted to use the tb hoses. Was shot down by the peanut gallery saying id was way to small to be useful.

Not sure where else could be that fast though, theres a handful of ways to pipe it in, but not minutes simple. Im using t-fittings on my radiator hoses.

Interior heating hoses ?

Great work with the videos mate....but too much talk and not a single picture of the installed part :paddle:

I have one installed. The coolant lines are to and from the throttle body.

I am using the throttle body coolant lines for my turbo.

How would the coolant lines be run in this situation?

Very interested in this since all of the other options looked pretty involved.
@Model Citizen, was the concern that using the throttle body hoses wouldn't provide sufficient cooling in a turbo application or NA?

Strictly speaking any cooling is better than none, so if you know you aren't pushing it too hard this might be a good option.

any application was what i was told.

still wanted to try it out of sheer ease of access.

but then i fount my t fittings, got some spare radiator hoses and tapped in that way, which did allow for a larger diameter hose.
