Default Engine OIL COOLERS

Okay, Looks like this may be an item I will need very soon. Water temps are very good at a max of 201 so far this year bur I have seen oil temps in the 242ish area and stay stable at 230-235. What system works well for the FI bunch................tell me what you know...Please

Oh and if you have pictures of where it mounts that would be great...............I have alot of STUFF on the car

Gary,
Ron Davis radiator with intregraded oil cooler.
DRM distribution block off the block, all braided lines.
Electirc Accusump and an electric water pump as well for me.
You are already have a vented hood.

I originally had a Ron Davis w/internal oil cooler but swapped it for a Dewitt without an internal oil cooler and a Setrab external oil cooler. The Setrab is mounted on the drivers side and vents into the wheel well. Water and oil temps are much lower.

Very Nice, what model did you use? Do you have any pictures of the mounting location? Damn turbos have a way of taking up a little room Thanks

Gary it was 85+ here the other day and my oil temps were in the 225-235 area along with the coolant in the 195-210 range. It's normal in our cars with the twins and should come down when your crusing on the hwy. I thought about an oc but like you found out there's very little room for one. I was going to run the type they use on F bodies next to the rad but elected not to.

Just don't run your car on a road course as you'll melt it. I'll leave you with this thought.

This is exactly what mine is seeing... I was curious. I still think an oil cooler is a good idea and certainly on my "to do" list. I went with a DeWitts radiator and did not want the integral cooler either.

Well it has only been 72 degrees here and I can get the oil temp to 225 on the hwy. so I think a OC is needed.

Just switch to a supercharger and your oil temperature issues will be solved.

Hmmmmmmmmmmmm..............what is your AFR like? I had the same issues when I was running 9.2 when we 1st started tunning.

225 is fine on the hwy even in 72 degree oat. I would hold off on pulling the trigger till it warms up some more and see what it's like then.

If I remember correctly it's about 12"-13" by 7 1/2" . It's mounted on a standoff enclosure about 1" away from the wheel well liner. The well has a cutout the size of the cooler and is covered with a mesh to protect the cooler from rocks. I don't have a pic, but I will take one and post it. Taking the oil cooler out of the radiator makes a difference in engine cooling....you just have to fab up mounting brackets and extend the lines.

Thanks for the info. That just might work in that location. If you get a chance to get me some pictures that would be great.

Now who knows about cut-offs (way to keep the oil from being to cold) is there a stat or something like that????

Hi RPM,
Are you saying that a separate oil cooler functions better (or the radiator) than the integrated radiator/oil cooler? Are there other pros and cons to these two different approaches?

What he is saying is that if you do not have the oil cooler running in the radiator you are not adding the heat of the oil into the cooling system. Also.. I don't like the way the coolers block the engine coolant flow through the radiator, certainly both of these would make a difference.

From an oil cooling perspective, the integrated one probably cools the oil better than a separate air to air would, I don't have any data to support it either way, but the heat transfer between the coolant would be much better than an air to air.

I am going to run a separate one as well... where to mount it.. that is the question.

Call Campbell Automotive , they built a great one for me . Wish I had a pic I could take for you , but they took the car to the Powerrama car show this weekend . It's mounted between the intercooler and rad , pretty stealth , looks good.

The water temp in the radiator isn't that much lower than the oil temps...good heat removal requires a substantial differential in temperatures. The external cooler pulls cool outside air from the opening directly in front of it and has a good temp differential....and as you said the oil isn't dumping heat into the radiator and compromising the engine cooling. For applications over 800rwhp the heat buildup is a problem. Seperating the oil and water cooling processes makes it more efficient with less localized heat buildup. I didn't notice a drop in oil pressure
