Let's talk oil coolers...

[Ecoboost_xsport]

More specifically, getting oil to an oil cooler. I'm in the beginning stages of figuring out an engine oil cooler setup that I need and am wondering, those of you who have one, where you sourced the oil from. I really like Improved Racing's product line so I am contemplating one of their sandwich adapters with -10AN fittings for an oil cooler as well as an integrated thermostat to control it. I kind of don't like sandwich adapters as I prefer an actual oil take off plate and remote mounting a filter bracket, but it may not be feasible in our application.

Looking for opinion out there on going sandwich (insert joke here) or finding a take off plate, not sure if there is one for our engine, and going remote.

Also, what temp thermostat do you guys prefer? 180deg I'm assuming...

Interested to see what you come up with.
I’ve been contemplating a set up using improved racing’s Micro Oil Scavenge Circulation Gear Pump and a cooler for the PTU. The largest benefit, outside of some cooling would be the increased volume of fluid.

I've been wanting to do some sort of PTU cooler as well, but I'm having a tough time figuring how to ensure the oil stays at the appropriate level within the PTU case. Since the PTU is a vented, and not sealed, case, with fluid not completely filling the case like a closed loop system would, it adds a level of complexity. The oil leaves the PTU hot and viscous, cools and enters cooler a bit less viscous, this can cause it to "back up" so to speak and may present problems. Does the IR setup address this? If so, that's a viable option for sure.

Is the coolant cooled one they have now on the pp model any good in testing?

Well, it does help somewhat. That cooler is just a bolted on housing on the side where the idler gear bearing sits, which has been the weak link in the PTU. Keep in mind, its just circulating hot engine coolant into the radiator so it can only be so effective. As I said, its for sure better than nothing, but as far as PTU goes, there could be a better cooling modification out there.

Wonder if tapping into it with an external pump and reservoir to give it its own dedicated coolant and air bypass radiator is any better?

I was originally thinking that for the engine oil cooler, got all what is needed but never got around to it. My performance shop had a 427 Cobra oil cooler laying around but I just kept the oem oil cooler.

Following! I’ve been thinking an engine oil cooler should be used...don’t know why no one cares to do it

Back to the motor oil though, what’s your beef with sandwich? A thermostatic sandwich plate should definitely fit and would be about the easiest way to accomplish a oil cooler install.

Not sayin it won't fit, I've just never used one. Whenever I've done oil coolers on previous molded cars, I usually had an aftermarket filter housing that incorporated AN fittings or used oil take off plates to get rid of of the stock housing all together and go remote filter housing.

I don't really have a "beef" necessarily, it just feels like a cheap, band-aid solution. But that's why I ask, if anyone has used one before, are they a compromise with oil flow?

Improved Racing has a really trick one with integrated thermostat that Im itching to pull the trigger on to get this ball rolling, but wanted to see what other options/solutions are out there.

MoCal is cool, I've always preferred Setrab coolers. But I'm also eyeballing the shit out of those Improved Racing bar and plate dual pass heat exchangers, lol...

Another issue...where to put it...there's plenty room, at least for me, in front of front driver side wheel, behind the bumper, but would require me find some way to cut a duct into the bumper...not impossible, just making it look decent would be nice.

There isn't much room to put it in front of an existing heat exchanger in my application, believe it or not.

Need a self-sustaining pump like this Delavan 7802-111 PowerFLO Electric Diaphragm Pump for the PTU. Says pump can handle water temp up to 140 degrees so got to figure out how hot the PTU fluid will get.
Can probably do the same principle with a oil cooler have its own pump.

That Improved Racing pump I mentioned Is good to 350°.

I have no personal experience with either set up but have heard good things from the old school small block Ford guys about that basic Mocal sandwich plate. It too has a integrated 180° stat.

Probably not as efficient as other setups and certainly not the most fancy.

Which leads me to my other concern. Tstat temp.

Ideally, you want the oil around 212 or so to burn off moisture, so 180 seems kind of low, especially if the car sees regular street time. At least that's my train of thought...

Valid concern, although opening to circulate at 180° doesn’t mean it’s keeping it there.

I know this is old but did anyone ever get a oil cooler installed with a good outcome?

You can go ahead and do this, whether someone chimes in, it’s a universal application. The main thing is you’ll want to use a sandwich adapter with a thermostat bc you will not want the oil constantly running through the cooler. Constant flow will increase warm up time considerably. Too cool is a thing. Mentioned here 180 degree thermostat sounds perfect. It’ll warm up fast and then start flowing after 180.

What are your goals? An engine oil cooler is very beneficial for extended operating time under WOT, like Time Attack, Circuit Track. It’s less practical for daily driving and not necessary for drag strip days but ….it will still work just fine. If you want added peace of mind I say go for it.

You’ll just need to find a good spot to mount it, where it’ll get decent airflow. Maybe make some simple brackets yourself to secure it.

Just don’t get a sandwich plate that does not have a thermostat. Don’t compromise fast oil temp warm up.

Evil Energy sent me an oil cooler and sandwich plate but it doesn’t have a thermostat so I’m not using it. Even for my goals at this time I’m not using one.

My goal is just longevity and peace of mind, I only drive her when it is nice out. (2015 non PP with 45000 miles) Any recommendations on hose size 6 or 8 AN. Should there be a concern with pressure drops when the thermostat opens? Thank you in advance.

For longevity and peace of mind, run –10AN. –6AN is too small and –8AN is borderline; –10AN gives proper flow margin with essentially no downside. With a quality bypass-style oil thermostat, there’s no concern about pressure drop when it opens, the transition is smooth and well within design limits. Bigger lines and a decent stacked-plate cooler keep the system low-stress and boring, which is exactly what you want for engine oil

Now I’m considering it again haha

Thank you for the info Bro...FYI you still have me wanting to do the air ride
